Abstract
A method of treating a body lesion associated with inadequate blood perfusion, partial denervation, tissue loss, pain, edema, and/or infection, comprising applying to a subject afflicted with a lesion, externally and non-invasively at a site removed from the lesion, analgesic, angiogenic, vasculogenic, nerve growth, osteogenic, anti-edema, anti-inflammation and/or wound repair effective electromagnetic fields (EMFs) comprising frequencies of a few Hertz to less than about 300 Hz and static magnetic field components from a few microTesla to a maximum intensity of about 0.3 to about 0.8 mT used alone or in combination with a homogeneous static magnetic field of about 40 to about 80 mT or about 400 to about 800 gauss.
Description
ELECTROMAGNETIC METHOD OF TREATMENT OF
LESIONS ASSOCIATED WITH INADEQUATE BLOOD
PERFUSION, PARTIAL DENERVATION, TISSUE LOSS, PAIN, EDEMA, INFLAMMATION & INFECTION
$ BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates generally to a method for treatment of skin lesions and internal wounds such as viable but underperfused myocardium. More specifically, this invention is related to a method for treatment of a subject afflicted with inadequate blood perfusion, tissue loss, partial denervation, wounds, bone fractures, burns and/or ulcers, by administration of time varying electromagnetic fields alone or simultaneously with static magnetic fields to the subject of specific characteristics.
Description of the Background Locally applied electromagnetic fields (EMFs) have been shown to increase skin and nerve regeneration, collagen maturation and tensile strength during healing of skin wounds in the rat. In vitro, EMFs have been shown also to induce the proliferation and collagen-mediated production of fibroblasts and foster angiogenesis. In addition, locally applied EMFs have long been known to promote soft tissue repair. Chronic venous leg ulcers and pressure ulcers have been treated by application of various therapies, including the local application of growth factors, hyperbaric oxygen, local infrared irradiation, EMFs, ultra violet and low energy lasers as well as ultrasound, directly to the ulcerated site. The Agency for Health Care Policy and Research of the U.
S. Department of Health and Human Services, however, recommended locally applied EMFs as the sole adjunctive therapy with sufficient supporting evidence for the treatment of pressure ulcers. Although the local application of EMFs has been used to treat chronic venous leg ulcers, nerve regeneration, bone nonunionis and to protect animal models from the sequela of provoked ischemia, all attempts to attain healing by administration of EMFs at a point distant from the afflicted site have failed up to the present time.
The ability of treating wounds and other ailments without administering the EMFs at the wound site while attaining an improvement, and even full healing of the wound, would be of great help, particularly in cases where the wound site is somewhat inaccessible or simply to avoid inconveniencing the patient. Such treatment could be administered on an out-patient basis, would not require highly skilled personnel and would reduce the cost of treatment while freeing medically trained personnel for the diagnosis and prescription of therapies and for following up the results attained in any particular round of applications.
Accordingly, there is a clear need for an improved method for accelerating and fostering of healing of a subject's wounds, particularly those wounds that prove to be resistant to other more conventional treatments, which is simple, does not inconvenience the subject, may be performed on an out-patient's basis by non-highly skilled personnel, and that does not inconvenience the patient.
Such treatment would be highly therapeutic and cost effective.

This invention relates to a method of treating lesions, burns, skin ulcers, and viable but underperfused myocardium, which comprises applying externally and non-invasive extremely iow frequency electromagnetic fields (EMFs) of specific characteristics to a subject afflicted with a ;.esion burn and ulcer, at a site removed from the site of the lesion under conditions effective to accelerate

SUMMARY OF THE INVENTION
This invention relates to a method of treating lesions, burns, skin ulcers, and viable but underperfused myocardium, which comprises applying externally and non-invasive extremely iow frequency electromagnetic fields (EMFs) of specific characteristics to a subject afflicted with a ;.esion burn and ulcer, at a site removed from the site of the lesion under conditions effective to accelerate
2 lesion, bum, bone or ulcer healing, to enhance angiogenesis and vasculogenesis and to improve the effect of other subsequently applied therapies. Suitable EMFs comprise a time-varying electromagnetic field component generated at frequencies of a few Hertz (more than one) to less than about 300 Hz and static magnetic field components having an intensity of about few micro Tesla, e.g., about 2-5 wT, about 20 wT to about 100 ~T, about 0.3 mT, about 0.8 mT.
These EMFs may be used alone or in combination with a homogeneous static magnetic field of about 40, about 50 to about 70, about 80 mT (or about 400, about 500 to about 700, about 800 Gauss).
Although in some cases, the measured frequencies inside the coils are about 0.3 to about 0.8 p,T, in those areas of the skin close but not inside the coils, the intensities of the EMF are progressively reduced down to the environmental magnetic fields.
The method of this invention is particularly suited for the therapeutic treatment of subjects afflicted with skin lesions such as burns, internal wounds such as bone fractures, partial denervation, and ulcers, particularly chronic wounds, such as venous and arterial leg ulcers, pressure ulcers, unhealing wounds, infected wounds, painful inflamed tissue, areas of inadequate blood perfusion, such as viable but underperfused myocardium and the like, which are present either by themselves or in association with other causes, e.g. atherosclerosis, varicose veins, diabetes, hypertension, rheumatoid arthritis, trauma, and the like. Some lesions are resistant or non-responsive to treatment with surgical or conservative conventional methods, but the administration of the present therapy makes them highly responsive to previously ineffective treatments. The present method may be administered for a short period of time as well as through periodically exposing an already treated subject to repeated treatments over a period of time effective for reducing the intensity of pain, edema, inflammation and infection, increasing angiogenesis, vasculogenesis, nerve regeneration, bone union and reestablishing the subject's own immune-mediated anti-inflammatory response and wound healing processes.
The present therapeutic method greatly reduces the healing time in subjects who had proved previously highly resistant to other conventional medical treatments.
The present invention will be further illustrated by reference to the various drawings and the several examples hereinafter described.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
This invention arose from a desire by the inventor to improve on prior art technology and various somewhat ineffective therapeutic treatments which, in addition, require direct administration to the site of the lesion. This makes them cumbersome, difficult to carry out, and definitely inconvenient to the patient.
The present inventor surprisingly discovered that when a subject with chronic skin lesions) and or internal wounds such as bone fracture, partial denervation or viable but underperfused myocardium, is treated by applying an electromagnetic field (EMFs) to a portion of the subject's body in accordance with this invention, the lesions show activated inflammatory reaction and wound repair, and as a result the lesions are drastically and readily reduced, and in many cases readily healed and/or completely eliminated. This is the case even for lesions that are resistant to other generally effective therapies. In viable but underperfused myocardium, the application of EMFs to a portion of the subject's body in accordance with this invention, produce increased collateral circulation and myocardial contraction which are expressed as better clinical improvement. The beneficial results obtained by the inventor are realized by subjecting a site of the subject's body such
5 as a limb, e.g. arm, hand, leg or foot, or even the whole body to the action of specific electromagnetic fields (EMFs) having specific constant and variable components. It is a matter of clinical experience that some subjects with internal and/or external lesions develop resistance to the action of the generally effective wound healing drngs and other therapies upon their administration over a period of time. In addition, other lesions, internal wounds, underperfused tissue, burns and ulcers remain unresponsive to these treatments throughout.
The present inventor has surprisingly found that when such subjects are exposed to external, non-invasive electromagnetic fields (EMFs) in accordance with this invention, they become responsive to previously ineffective treatments, e.g., with known wound healing drugs and other therapies. Many subjects that may benefit from the present treatment have histories of acute myocardial infarction, venous or arterial leg ulcers, bums, pressure ulcers, surgically infected wounds, bone fractures, tissue loss, partial denervation, inadequate blood perfusion and painful inflamed soft tissue, among others, which are resistant or non-responsive to treatment with surgical, pharmacological, or more conventional methods available.
This invention utilizes especially configured electromagnetic fields (EMFs) which may be advantageously applied at a site removed from the wound. The present EMFs stimulate a subject's immune system, including and preferably the subject's activated and memory peripheral blood mononuclear cells (PBMCs); although EMF's action on other EMF's exposed body tissues is not excluded. An activation of the subject's immune system elicits a natural response providing the lesion site and other areas of immune neuroendocrine regulation with the necessary cells, cytokines, angiogenic, osteogenic and neural growth factors, hormones and other immunomodulators which bring about the therapeutic healing of lesions such as burns, venous and arterial leg ulcers, pressure ulcers, chronic infected wounds internal or external areas with inadequate blood perfusion such as viable but underperfused myocardium and the like, muscle loss, bone fractures, partial denervation, painful inflamed soft tissue, and other skin lesions. The electromagnetic fields (EMFs) of this invention comprise time-varying magnetic fields, i.e. alternating currents that oscillate at specified frequencies. In one embodiment of the present invention, the alternating currents are generated in a solenoid with frequencies that range from a few Hertz (more than about 1 cycle per second), about 10 Hertz, about 50 Hertz to about 100 Hertz, about 200 Hertz, about 300 Hertz, with maximum intensities around 120 Hertz and its harmonics. See Figure 5 of this patent.
These time varying magnetic fields have small static magnetic fields associated to them from a few microTeslas, e.g.
about 2-5 ~T, about 10 ~T, to about 100 ~T, about 0.3, about 0.8 mT. Strong static magnetic fields with an intensity of about 40, about 50 to about 60 ~T, about 70 ~T, about 80 mT (400 to 800 gauss), are generated by the motion of electrons around atoms and of electrons in crystal lattices within the permanent magnets of this invention placed around the solenoid.
The present method attains healing of a wounded tissue either directly or through immune cells or other exposed tissues or through cell's products, and affords a reduction of pain, edema and infection while restoring or stimulating the subject's immune- mediated signaling network which is necessary to increase angiogenesis, vasculogenesis and wound repair. When a body part such as the arm or the whole body is exposed to the ENTs of this invention, PBMCs as well as other tissues such as the skin, muscle, blood and lymphatic vessels, erythrocytes, bone, nerve and extra cellular matrix, are under the EMFs effects of this invention. Under these conditions the tissues simultaneously exposed, could be stimulated to secrete products that act at a distance in the wound, in she underperfused tissue, in the partially denervated area, in bone fracture healing or in the imr.:une neuroendocrine centers contributing to the regulation of wound repair.
The present inventor has surprisingly found that when such subjects are exposed to external, non-invasive electromagnetic fields (EMFs) in accordance with this invention, they become responsive to previously ineffective treatments, e.g., with known wound healing drugs and other therapies. Many subjects that may benefit from the present treatment have histories of acute myocardial infarction, venous or arterial leg ulcers, bums, pressure ulcers, surgically infected wounds, bone fractures, tissue loss, partial denervation, inadequate blood perfusion and painful inflamed soft tissue, among others, which are resistant or non-responsive to treatment with surgical, pharmacological, or more conventional methods available.
This invention utilizes especially configured electromagnetic fields (EMFs) which may be advantageously applied at a site removed from the wound. The present EMFs stimulate a subject's immune system, including and preferably the subject's activated and memory peripheral blood mononuclear cells (PBMCs); although EMF's action on other EMF's exposed body tissues is not excluded. An activation of the subject's immune system elicits a natural response providing the lesion site and other areas of immune neuroendocrine regulation with the necessary cells, cytokines, angiogenic, osteogenic and neural growth factors, hormones and other immunomodulators which bring about the therapeutic healing of lesions such as burns, venous and arterial leg ulcers, pressure ulcers, chronic infected wounds internal or external areas with inadequate blood perfusion such as viable but underperfused myocardium and the like, muscle loss, bone fractures, partial denervation, painful inflamed soft tissue, and other skin lesions. The electromagnetic fields (EMFs) of this invention comprise time-varying magnetic fields, i.e. alternating currents that oscillate at specified frequencies. In one embodiment of the present invention, the alternating currents are generated in a solenoid with frequencies that range from a few Hertz (more than about 1 cycle per second), about 10 Hertz, about 50 Hertz to about 100 Hertz, about 200 Hertz, about 300 Hertz, with maximum intensities around 120 Hertz and its harmonics. See Figure 5 of this patent.
These time varying magnetic fields have small static magnetic fields associated to them from a few microTeslas, e.g.
about 2-5 ~T, about 10 ~T, to about 100 ~T, about 0.3, about 0.8 mT. Strong static magnetic fields with an intensity of about 40, about 50 to about 60 ~T, about 70 ~T, about 80 mT (400 to 800 gauss), are generated by the motion of electrons around atoms and of electrons in crystal lattices within the permanent magnets of this invention placed around the solenoid.
The present method attains healing of a wounded tissue either directly or through immune cells or other exposed tissues or through cell's products, and affords a reduction of pain, edema and infection while restoring or stimulating the subject's immune- mediated signaling network which is necessary to increase angiogenesis, vasculogenesis and wound repair. When a body part such as the arm or the whole body is exposed to the ENTs of this invention, PBMCs as well as other tissues such as the skin, muscle, blood and lymphatic vessels, erythrocytes, bone, nerve and extra cellular matrix, are under the EMFs effects of this invention. Under these conditions the tissues simultaneously exposed, could be stimulated to secrete products that act at a distance in the wound, in she underperfused tissue, in the partially denervated area, in bone fracture healing or in the imr.:une neuroendocrine centers contributing to the regulation of wound repair.
6 The present invention, thus, relates to a method of treating a body lesion associated with pain, edema, inflammation, bone fractures, partial denervation and/or infection, impaired wound repair and/or underperfused tissue such as viable but underperfused myocardium and the like, inadequate blood perfusion at the site of the lesion, and/or who exhibit an impaired immune-mediated inflammatory response and wound repair process which comprises applying to a subject afflicted with a lesion, externally and non-invasively and at a site removed from the lesion, analgesic, angiogenic, vasculogenic, nerve growth, anti-edema and wound repair effective electromagnetic fields (EMFs) comprising frequencies of a few Hertz, preferably about 0.1 Hz, about 1 Hz, about 5 Hz, about 10 Hz, about 20 Hz, about 60 Hz, about 80 Hz, about 100 Hz, about 120 Hz to less than about 180 Hz, about 240 Hz, about 300 Hz, and static magnetic field components having a minimum intensity of a few microTesla, e.g. about 2-4 ~,T, about 10 ~.T , about 50 ~T, about 100 ~,T
to about 0.3, about 0.4, about 0.5, about 0.6, about 0.7, about 0.8 mT. These EMFs may be used alone or in combination with a static magnetic field of about 40, about 50 to about 70, about 80 mT (or about 400, about 450, about 500, about 550 Gauss to about 600, about 650, about 700, about 800 Gauss).
1 S In the method of invention, the EMFs may be applied to a limb of the subject, that is to an arm or a leg, and in some instances to a hand or a foot, to other parts of the subject's body, or to the whole body. The present method may be conducted for various periods of time, including about 5 minutes to about 7 hours per administration. In one preferred embodiment, the electromagnetic fields (EMFs) administration is conducted over a period of time effective to expose the subject's entire blood volume at least once to the EMFs. This procedure ensures that the entire blood volume is exposed to the EMFs and the inductive effect imparted to all cells present in the blood stream, particularly activated and memory peripheral blood mononuclear cells, and their progenitor cells.
Although in many cases, one application of the electromagnetic fields (EMFs) may suffice, the application may be repeated as many times as necessary. Preferably once a week, twice a week, 3, 4, 5, 6, and 7 times a week and up to about 1, 2, 3, 4, 5, 6, 7 and 8 weeks, and even several months and years. In addition, the method also includes the periodic reapplication of EMFs.
The method of this invention may be applied to the treatment of diseases and conditions associated with and/or caused by, and/or resulting in, a body lesion(s). In all cases, a sufficient number of applications of the electromagnetic fields (EMFs) maybe delivered until the lesion is alleviated and/or fully healed. Among the lesions that may be treated with the present technology are chronic wounds, partial denervation, loss of muscular tissue, bone fractures, bums, lesions caused by inadequate blood perfusion, such as viable but underperfused myocardium and the like, consequences of unsuccessful surgery, and different types of venous, arterial and vascular problems, including arterial and venous ulcers. Examples of various lesions and their descriptions are provided below as well as the various other treatments presently available and their degree or lack of success in overcoming the diseases and conditions.
~ARONIC VENOUS AND ARTERIAL LEG ULCERS
I. chronic Venous Leg Ulcers Initially, chronic venous leg ulcers are generally caused by venous insufficiency and valve incompetence that lead to increased ambulatory pressure. This effect extends, in most cases to small veins, venules and capillaries. The pressure results in augmented interendothelial spaces, which, in turn, enhance extravasion of small solutes, macromolecules and blood cells.
This is seen as a leakage of small and large molecules as well as blood cells out of the endothelial tissues and into the interstitial space. Concurrent with this, lymphoangiopathy and reduced lymphatic drainage are seen, which result in fall clinical edema. Slow blood flow develops and increased adherence of white blood cells and platelets to endothelium leads to the formation of microthrombi which reduce the
to about 0.3, about 0.4, about 0.5, about 0.6, about 0.7, about 0.8 mT. These EMFs may be used alone or in combination with a static magnetic field of about 40, about 50 to about 70, about 80 mT (or about 400, about 450, about 500, about 550 Gauss to about 600, about 650, about 700, about 800 Gauss).

The present method may be conducted for various periods of time, including about 5 minutes to about 7 hours per administration. In one preferred embodiment, the electromagnetic fields (EMFs) administration is conducted over a period of time effective to expose the subject's entire blood volume at least once to the EMFs.

The method of this invention may be applied to the treatment of diseases and conditions associated with and/or caused by, and/or resulting in, a body lesion(s). In all cases, a sufficient number of applications of the electromagnetic fields (EMFs) maybe delivered until the lesion is alleviated and/or fully healed. Among the lesions that may be treated with the present technology are chronic wounds, partial denervation, loss of muscular tissue, bone fractures, bums, lesions caused by inadequate blood perfusion, such as viable but underperfused myocardium and the like, consequences of unsuccessful surgery, and different types of venous, arterial and vascular problems, including arterial and venous ulcers. Examples of various lesions and their descriptions are provided below as well as the various other treatments presently available and their degree or lack of success in overcoming the diseases and conditions.
~ARONIC VENOUS AND ARTERIAL LEG ULCERS
I. chronic Venous Leg Ulcers Initially, chronic venous leg ulcers are generally caused by venous insufficiency and valve incompetence that lead to increased ambulatory pressure. This effect extends, in most cases to small veins, venules and capillaries. The pressure results in augmented interendothelial spaces, which, in turn, enhance extravasion of small solutes, macromolecules and blood cells.
This is seen as a leakage of small and large molecules as well as blood cells out of the endothelial tissues and into the interstitial space. Concurrent with this, lymphoangiopathy and reduced lymphatic drainage are seen, which result in fall clinical edema. Slow blood flow develops and increased adherence of white blood cells and platelets to endothelium leads to the formation of microthrombi which reduce the
7 number of capillaries present. These changes ultimately lead to necrosis, which is substituted by fibrous tissue, which predispose the skin of the gaiter area to ulceration.
L1 Venous Leg Ulcers Treatment Most macrovascular alterations may be conservatively treated by leg-elevation, external S graduated compression and/or surgical procedures. Microvascular changes are targeted by means of systemic pharmacological treatment with, for example, venotonic drugs, platelet aggregation inhibitors, white blood cells activation inhibitors and fibrinolytic and thrombolytic agents, which are among the most commonly prescribed medicines. However at present no convincing evidence exists to recommend these agents in venous leg ulcer treatment.
II. Chronic Arterial Leg Ulcers In most cases, atherosclerosis of the lower limbs is the first cause of arterial leg ulcers and it leads to a progressive narrowing of the arterial lumen and a gradual reduction of blood flow to the distal circulation. As the disease progresses, the atherosclerotic lesions generally extend. When the blood flow becomes sufficiently reduced and the perfusion pressure of nutritional capillaries uneven, insufficient nutritional support of peripheral microcirculation ensues. In addition, an increase in leukocyte adhesion, platelet aggregation, rheological alterations and arteriolar microthrori~bi are observed. These contribute to further reducing the number of perused capillaries. The described arterial alterations are expressed clinically as rest pain, throphic skin changes and ulceration. In addition, these lesions often get infected.
IL1 Chronic Arterial Leg Ulcer Treatment Present invasive treatments include angioplasty, vascular reconstruction and amputation.
Most pharmacological treatments are focused to reduce pain, and to reduce infection. At present the European Consensus for Critical Leg Ischemia does not recommend any additional pharmacological treatment for arterial leg ulcers.
III. pressure Ulcers lDecubitus Ulcersl Most pressure ulcers are commonly produced as a consequence and a complication of immobility. In many instances, they are resistant to medical treatment. This resistance is greatly increased by malnutrition, infections and old age. These ulcers generally increase the risk of death of patients that remain for extended periods in acute care hospitals and nursing homes. In spinal cord injured patients, for example, this problem accounts for 7-8% of deaths.
Although pressure, friction, shearing forces and moisture have been implicated in the pathogenesis of skin breakdown, the process may be also aggravated by secondary infection.
IIL1 Pressure Ulcer (Decubitus Ulcers) Treatment A most common treatment starts with the repositioning of the patient to avoid prolonged pressure in any specific area of the body. In addition to this, the basic treatment procedures commonly applied to these patients are general wound care and treatments aimed to control the basic disease. The patients are also advised on adequate nutritional habits and recommended to take supplements of ascorbic acid, zinc, and selenium.
IV. Chronic Wounds In most cases of chronic wounds, inadequate nutritious blood supply, edema, tissue anoxia, cell death and infection, reinforced by aging and sustained stress, reduce peptide signaling among cells involving growth factors, hormones and the like as well as their effects in the immune-neuroendocrine communication network. Healing is impaired due to the absence of a normal immune-mediated inflammatory response and/or repair process. The presently available treatments are only partially effective and the long-term prognosis is poor for these patients. The present status

The presently available treatments are only partially effective and the long-term prognosis is poor for these patients. The present status
8 emphasizes the need of new methods to treat chronic wounds such as activating the cell's and cytokine's signaling language necessary for wound repair, nerve growth, vasculogenesis and angiogenesis.
V. MyocardialInfarction Atherosclerosis is a generalized disease responsible for occlusive arterial disease such as lower-limb arterial disease (chronic arterial leg ulcers), myocardial infarction and stroke. The etiologic factors (arterial hypertension, high serum cholesterol, smoking, stress, diabetes mellitus) are similar in these diseases. Most deaths in patients with myocardial infarction are caused by arrythmias, infarct expansion and post-infarction remodeling.
V.1 Myocardial Infarction Treatment Preventive measurements are focused to eliminate or control the etiological factors.
Reduction of early mortality of myocardial infarction can be achieved by the use of B-blockers, thrombolytic therapy followed by catheter based revascularization, angioplasty with or without stenting, by-pass surgery, angiotensin converting enzyme inhibitors and aspirin. To those patients 1 S with viable but underperfused myocardium who are not candidates for coronary revascularization, angiogenic growth factors are a novel approach still under clinical investigation.
VI. Bone Fractures In bone fractures, three overlapping phases of fracture healing have been described: a) the inflammatory phase which is similar to the inflammatory stage of an skin wound. b) the reparative phase in which osteoblast proliferation and endosteal tissues are central for callus _formation. a~.d c) the remodeling phase, where the fracture callus and bone are remodeled to restore normal shape and strength. In the three phases of fracture healing PBMCs and cytokines play a central role. Current treatment includes surgery, fixation and locally applied electromagnetic fields to induce osteogenesis.
VII. Spinal Muscular Athro~hies The spinal muscular athrophies of infancy and childhood are diseases in which there is a progressive degeneration of the motor neurons of the spinal cord, with early age of onset and genetic determination. Although clinically resembling muscular dystrophies, in these patients the muscular atrophy is secondary to nerve degeneration. Some infants develop normally for several months before weakness become apparent. The trunk, pelvic and shoulder girdle muscle groups are disproportionally affected. The disease runs a steadily downhill course, and most patients have a short period of life. A few may survive for several years, and even are able to work with support.
At the present time there is no cure for these diseases. Treatment is restricted to rehabilitation therapy and orthopaedic support. New approaches to nerve regeneration are neurothophic factors, Schwann cells manipulation, and locally applied electric currents or electromagnetic fields to induce electric currents, although these treatments are not used to treat spinal muscular atrophies.
Types of diseases and conditions which are normally associated with body lesions are, for example, partial denervation, tissue loss, bums, bone fractures, ischemic and traumatic lesions, chronic wounds and ulcers. By means of more specific examples, the following diseases and conditions have been observed to fall in the above described categories:
diseases and conditions accompanied by inadequate blood perfusion such as viable but underperfused myocardium and the like, tissue necrosis, pain, edema and infection, such as internal and external chronic wounds, produced by atherosclerosis, arterial hypertension, diabetes, vasculitis, venous insufficiency, varicose veins, deep vein thrombosis, rheumatoid arthritis, prolonged immobility obesity, vascular necrosis, chronic wounds and aggravated bums, lesions produced by trauma, burns and surgery. The present treatment is particularly suitable for application to conditions where nutritious blood supply and tissue regeneration is needed such as skin, muscle, nerve and connective tissue including, but not lii-nited to

Types of diseases and conditions which are normally associated with body lesions are, for example, partial denervation, tissue loss, bums, bone fractures, ischemic and traumatic lesions, chronic wounds and ulcers. By means of more specific examples, the following diseases and conditions have been observed to fall in the above described categories:
diseases and conditions accompanied by inadequate blood perfusion such as viable but underperfused myocardium and the like, tissue necrosis, pain, edema and infection, such as internal and external chronic wounds, produced by atherosclerosis, arterial hypertension, diabetes, vasculitis, venous insufficiency, varicose veins, deep vein thrombosis, rheumatoid arthritis, prolonged immobility obesity, vascular necrosis, chronic wounds and aggravated bums, lesions produced by trauma, burns and surgery. The present treatment is particularly suitable for application to conditions where nutritious blood supply and tissue regeneration is needed such as skin, muscle, nerve and connective tissue including, but not lii-nited to
9 viable but underperfused myocardium, ulcers such as venous ulcers, arterial ulcers, decubitus ulcers, deep pressure ulcers, medial malleolus ulcers, factitial ulcers, ulcers produced by trauma and surgery and lower limb ulcers, spinal muscle atrophy, among others. The lower limb ulcers are individually or collectively located on different areas of the subject's leg or foot.
Wounds that are treatable with $ the present method are of surgical or non-surgical origin. Common non-surgical wounds are viable but underperfused myocardium, chronic venous and arterial leg ulcers, pressure ulcers and the like and common surgical wounds are wounds associated with or caused by surgery, silicon implants or by a surgical drainage. Typical diseases and conditions associated with or causing inadequate blood perfusion, are for example: atherosclerosis, venous insufficiency, deep vein thrombosis venous and arterial hypertension, vasculitis, diabetes, rheumatoid arthritis, obesity, and diseases associated with long periods of inactivity, such as those occurring when a subject sits or lies down for an extended period of time.
The present method is also suitable for increasing the effect of a treatment applied to a body lesion associated with pain, edema and/or inflammation. In many cases, a patient on whom a treatment was previously ineffective is made to respond to the same treatment upon a series of electromagnetic fields (EMFs) applications. The present method does, in this manner, increase the subject responsiveness to the treatment, which, in turn, results in alleviation of the body lesion and the pain, edema and/or inflammation accompanying it.
The present method is of particular value where a subject had become resistant to the agent for treating the disorder or condition, and the application of the electromagnetic fields (EMFs) restores the ability of pharmaceutical or surgical treatments to improve the subject's health and mobility. Examples of such treatments are angioplasty, surgery, saphenectomy, skin grafts, wound closure, stitching, bandaging, anti-hypertensive therapy, pharmaceutical composition administration, nursing care and body lesion clean up, among others. Examples of pharmaceutical compositions which are typically administered to patients afflicted with the sort of lesions described above are pain killers, anti-inflammatory agents, antibiotics, flavinoids, tissue plasminogen activator, aspirin, prostacyclin analogs, prostanoids, venotonic drugs, fibrinolytic and thrombolytic agents, diets and the like. These agents may also be administered in conjunction with or subsequent to the administration of EMFs in accordance with this invention.
The preferred embodiments of the invention will now be described with reference to the drawings in so far as this may facilitate the understanding of this invention.
The present treatment may be applied with the apparatus of the invention exemplarily illustrated in Figures 1-2, 8-9, 10-11, 14-15, 17-18, 19-20, 22-23 and 25-26. The designs of the various embodiments of the present apparatus are derived from observations made in patients with similar problems that were exposed to time-varying magnetic fields of this invention, either alone, or in combination, with static magnetic fields. Figures 1-9 illustrate the use of time-varying magnetic fields in combination with static magnetic fields. Figures 8 and 9 illustrate an enlarged embodiment of this invention which has a large enough internal chamber to expose a large part of part of a human body such as the torso.
In particularly preferred embodiments of the apparatus used many times with success, the permanent magnets are eliminated but the time-varying electromagnetic fields are maintained. See, Figures 10 to 16. Another embodiment provides an apparatus similar to the one previously described but equipped with a large enough internal chamber to expose a part of the human body, e.g. from the upper limit of the aorta to the lower limit of the liver and spleen, inside the chamber to the magnetic field. See, Figures 17 and 18. In this manner time-varying magnetic fields of the same characteristics can be applied to the patient's large blood and lymph vessels:
aorta, vana cava and thoracic duct, as well as to the large blood and lymph reservoirs: heart, lung, liver, spleen, and paravertebral ganglia. This treatment simultaneously exposes large numbers of peripheral blood mononuclear cells to the electromagnetic fields, and reduces treatment time.
These embodiments of the apparatus were designed to provide a comfortable position for the patient during exposure to the magnetic fields.
In still another embodiment of the apparatus of the invention, the characteristics of the time varying magnetic fields are the same as in the above-described apparatus but are generated by, for 5 example, two parallel coils, i.e. Hemholtz coils. The coils produce homogeneous electromagnetic fields in the center between them. This embodiment can be used to expose part of the human body lying on a bed to the time varying magnetic fields. See, Figures 19-22.
Yet another embodiment provides a slight variation of the apparatus described above, but where similar equipment is placed upside down and fixed-to the sides of a narrow bed made of non
Wounds that are treatable with $ the present method are of surgical or non-surgical origin. Common non-surgical wounds are viable but underperfused myocardium, chronic venous and arterial leg ulcers, pressure ulcers and the like and common surgical wounds are wounds associated with or caused by surgery, silicon implants or by a surgical drainage. Typical diseases and conditions associated with or causing inadequate blood perfusion, are for example: atherosclerosis, venous insufficiency, deep vein thrombosis venous and arterial hypertension, vasculitis, diabetes, rheumatoid arthritis, obesity, and diseases associated with long periods of inactivity, such as those occurring when a subject sits or lies down for an extended period of time.
The present method is also suitable for increasing the effect of a treatment applied to a body lesion associated with pain, edema and/or inflammation. In many cases, a patient on whom a treatment was previously ineffective is made to respond to the same treatment upon a series of electromagnetic fields (EMFs) applications. The present method does, in this manner, increase the subject responsiveness to the treatment, which, in turn, results in alleviation of the body lesion and the pain, edema and/or inflammation accompanying it.
The present method is of particular value where a subject had become resistant to the agent for treating the disorder or condition, and the application of the electromagnetic fields (EMFs) restores the ability of pharmaceutical or surgical treatments to improve the subject's health and mobility. Examples of such treatments are angioplasty, surgery, saphenectomy, skin grafts, wound closure, stitching, bandaging, anti-hypertensive therapy, pharmaceutical composition administration, nursing care and body lesion clean up, among others. Examples of pharmaceutical compositions which are typically administered to patients afflicted with the sort of lesions described above are pain killers, anti-inflammatory agents, antibiotics, flavinoids, tissue plasminogen activator, aspirin, prostacyclin analogs, prostanoids, venotonic drugs, fibrinolytic and thrombolytic agents, diets and the like. These agents may also be administered in conjunction with or subsequent to the administration of EMFs in accordance with this invention.
The preferred embodiments of the invention will now be described with reference to the drawings in so far as this may facilitate the understanding of this invention.
The present treatment may be applied with the apparatus of the invention exemplarily illustrated in Figures 1-2, 8-9, 10-11, 14-15, 17-18, 19-20, 22-23 and 25-26. The designs of the various embodiments of the present apparatus are derived from observations made in patients with similar problems that were exposed to time-varying magnetic fields of this invention, either alone, or in combination, with static magnetic fields. Figures 1-9 illustrate the use of time-varying magnetic fields in combination with static magnetic fields. Figures 8 and 9 illustrate an enlarged embodiment of this invention which has a large enough internal chamber to expose a large part of part of a human body such as the torso.
In particularly preferred embodiments of the apparatus used many times with success, the permanent magnets are eliminated but the time-varying electromagnetic fields are maintained. See, Figures 10 to 16. Another embodiment provides an apparatus similar to the one previously described but equipped with a large enough internal chamber to expose a part of the human body, e.g. from the upper limit of the aorta to the lower limit of the liver and spleen, inside the chamber to the magnetic field. See, Figures 17 and 18. In this manner time-varying magnetic fields of the same characteristics can be applied to the patient's large blood and lymph vessels:
aorta, vana cava and thoracic duct, as well as to the large blood and lymph reservoirs: heart, lung, liver, spleen, and paravertebral ganglia. This treatment simultaneously exposes large numbers of peripheral blood mononuclear cells to the electromagnetic fields, and reduces treatment time.
These embodiments of the apparatus were designed to provide a comfortable position for the patient during exposure to the magnetic fields.
In still another embodiment of the apparatus of the invention, the characteristics of the time varying magnetic fields are the same as in the above-described apparatus but are generated by, for 5 example, two parallel coils, i.e. Hemholtz coils. The coils produce homogeneous electromagnetic fields in the center between them. This embodiment can be used to expose part of the human body lying on a bed to the time varying magnetic fields. See, Figures 19-22.
Yet another embodiment provides a slight variation of the apparatus described above, but where similar equipment is placed upside down and fixed-to the sides of a narrow bed made of non
10 magnetic material. The magnetic flux produced by the coils now runs perpendicular to the body axis.
The controls may be easily located at bedside, as shown. See, Figure 23.
Another embodiment of the present apparatus is provided with coils arranged in a saddle disposition so the magnetic fields run perpendicular to the limb. This equipment was built for veterinary applications and has been successfully used to cure an inflamed joint and skin wound of a horse. However, it may also be used in humans. See, Figures 25 to 28.
In still two further embodiments of the invention, the electromagnetic fields of this invention may be generated in two different manners. One manner is where the electromagnetic fields are generated by modulating continuous about 27.12 Mhz waves that transport electrical and magnetic energy through space (transporting wave) at the same or similar frequencies of the present invention (i.e.: an antenna to focus the electromagnetic fields of the present invention in any direction). The other way is by modulating electromagnetic fields of high intensity and frequency (transporting waves) such as those electromagnetic fields produced by a Tesla coil, to the same or similar frequencies as employed in the present invention. In the latter case, the electromagnetic fields traveling through space may reach a patient lying in bed or seated without being attached to the apparatus.
With reference to Figures 1 and 2, an embodiment of the apparatus of the present invention may be in the general form of a rectangular or square box 101, which may be fabricated from wood, plastic or other non-magnetic material to prevent interference with the application of an electromagnetic field to a patient's body part. The front or face panel 103 of the apparatus may have generally a circular opening 104 which extends as a elongated annular passageway 105 in the box 101. The passageway 105 generally extends horizontally inside the box 101, and when not in use, it may be closed and has an end 109 at the rear wall or panel 111. Preferably installed on the face panel 103 are a timer 113 and a control mechanism 115, both of which are connected to an electronic panel 117, for varying and controlling the intensity and duration of the magnetic field(s).
As shown in Figure 6, disposed on each interior longitudinal side of the passageway 105 is a solenoid coil 119 for supplying a time-varying magnetic field. In addition, Figure 6 shows the permanent magnets 121 for supplying the static magnetic field. Referring to Figure 7, an electric current is supplied from an AC power source (not shown) through power lines 123, 125, and into a transformer 127 and a rectifier bridge 129 to the magnetic coil 119. The manner and details for supplying electric current to the solenoid are well known in the art, and are not per se critical in this invention.
With reference to Figures 8 and 9, another embodiment provides an apparatus similar to the one described in the previous paragraph. This embodiment is an enlarged version of the embodiment shown in Figures 1 to 7. This second embodiment allows exposure to a part or the whole body to the EMFs as shown in Figures 8 and 9. In this design, the major blood vessels (aorta, cava veins) thoracic duct, paravertebral lymph nodes and major blood reservoirs (liver, spleen, lung and heart)
The controls may be easily located at bedside, as shown. See, Figure 23.
Another embodiment of the present apparatus is provided with coils arranged in a saddle disposition so the magnetic fields run perpendicular to the limb. This equipment was built for veterinary applications and has been successfully used to cure an inflamed joint and skin wound of a horse. However, it may also be used in humans. See, Figures 25 to 28.

Referring to Figure 7, an electric current is supplied from an AC power source (not shown) through power lines 123, 125, and into a transformer 127 and a rectifier bridge 129 to the magnetic coil 119. The manner and details for supplying electric current to the solenoid are well known in the art, and are not per se critical in this invention.
With reference to Figures 8 and 9, another embodiment provides an apparatus similar to the one described in the previous paragraph. This embodiment is an enlarged version of the embodiment shown in Figures 1 to 7. This second embodiment allows exposure to a part or the whole body to the EMFs as shown in Figures 8 and 9. In this design, the major blood vessels (aorta, cava veins) thoracic duct, paravertebral lymph nodes and major blood reservoirs (liver, spleen, lung and heart)
11 can be exposed simultaneously to the combination of time-varying magnetic fields and static magnetic fields (not shown), reducing the patient exposure time.
This apparatus has a circular shaped housing 130 containing the coil 119 and strong permanent magnets 121. The circular shaped housing 130 has an internal chamber 132 large enough to expose part of the body of a patient 134 to the magnetic field. The housing 130 may be fixed to a narrow bed 136 made of non-magnetic material. The timer 113 and control mechanism 115 connected to an electronic panel, as in the previous embodiment, may be located at the side of the bed. Preferably, the housing is made from a non-magnetic material such as wood or plastic.
In another embodiment shown in Figures 10 and 11, the identical apparatus of the embodiment of Figures 1 and 2 is used without the permanent magnets 121. As shown in Figure 13, this embodiment also includes a coil support 250 for supporting the coil 119 and a tube wall 252.
In another embodiment, shown in Figures 14 to 16, which is a simplified version of the previous embodiment shown in Figures 10 to 13, a solenoid, such as a magnetic coil 157, is mounted within a cylindrically shaped housing 158. The cylindrically shaped housing 158 includes an elongated annular passage 159 formed therethrough. The magnetic coil 157 is disposed within the cylindrically shaped housing 158 and around the annular passage 159. The housing and the annular passage are sized to comfortably accommodate the limb of a patient, such as the forearm 160 or upper arm 162 of a patient, allowing more mobility to the patient while being exposed to the EMFs.
Therefore, this design permits comfortable and mobile limb exposure to the ENVs of the invention. Preferably, the cylindrically shaped housing is made of a light non-magnetic material.
Such non-magnetic materials include plastic or wood. Also, the transformer 127 and rectifier bridge 129 (shown in Figure 7), along with a pair of contacts 152 which are connectable to a power source, are contained within a small adapter box 150, to readily obtain electric current from an AC power source (not shown). The adapter box 150 with the contacts, the transformer, and the rectifier bridge contained therein, is connected to the coil 157 by two long cables 154 which provide current to the coil 157.
With reference to Figures 17 and 18, another embodiment provides an apparatus similar to the embodiment shown in Figures 10 to 13. This embodiment is an enlarged version of the embodiment shown in Figures 10 to 13. This embodiment allows a part or the whole body to be exposed to the EMFs as shown in Figures 17 and 18. In this design the major blood vessels (aorta and cava veins) thoracic duct, paravertebral lymph nodes and major blood reservoirs (liver, spleen, lung and heart) can be exposed simultaneously to EMFs (not shown), reducing the patient exposure time. This apparatus has a circular shaped housing 260 containing the coil 119 and includes an internal chamber 262 large enough to expose part of the body of a patient 204 to the magnetic field.
The housing 260 may be fixed to a narrow bed 245 made of non-magnetic material. The timer 113 and the control mechanism 115 connected to an electronic panel, may be located at the side of the bed. Preferably, the housing is made from a non-magnetic material such as wood or plastic.
A magnetic field may also be applied with another embodiment illustrated in Figures 19 and 20. This apparatus may be in the general form of a U- shaped housing 200.
Referring to Figure 22, part of the body of a patient 204 may be exposed to a homogeneous electromagnetic field in accordance with this invention between the lateral walls 208 of the housing 200 of the apparatus.
The apparatus may be fabricated from wood, plastic, or other non-magnetic material, to prevent interference with the application of an electromagnetic field to a patient's body part. With reference again to Figure 19, installed on the face panel 212 are a timer 214 and a control mechanism 216, both of which are connected to an electronic panel 218 shown in Figure 20, for varying and controlling the intensity and duration of the electromagnetic field(s).
This apparatus has a circular shaped housing 130 containing the coil 119 and strong permanent magnets 121. The circular shaped housing 130 has an internal chamber 132 large enough to expose part of the body of a patient 134 to the magnetic field.

Preferably, the housing is made from a non-magnetic material such as wood or plastic.
In another embodiment shown in Figures 10 and 11, the identical apparatus of the embodiment of Figures 1 and 2 is used without the permanent magnets 121. As shown in Figure 13, this embodiment also includes a coil support 250 for supporting the coil 119 and a tube wall 252.
In another embodiment, shown in Figures 14 to 16, which is a simplified version of the previous embodiment shown in Figures 10 to 13, a solenoid, such as a magnetic coil 157, is mounted within a cylindrically shaped housing 158. The cylindrically shaped housing 158 includes an elongated annular passage 159 formed therethrough.

A magnetic field may also be applied with another embodiment illustrated in Figures 19 and 20. This apparatus may be in the general form of a U- shaped housing 200.
Referring to Figure 22, part of the body of a patient 204 may be exposed to a homogeneous electromagnetic field in accordance with this invention between the lateral walls 208 of the housing 200 of the apparatus.
The apparatus may be fabricated from wood, plastic, or other non-magnetic material, to prevent interference with the application of an electromagnetic field to a patient's body part. With reference again to Figure 19, installed on the face panel 212 are a timer 214 and a control mechanism 216, both of which are connected to an electronic panel 218 shown in Figure 20, for varying and controlling the intensity and duration of the electromagnetic field(s).
12 As shown in Figure 20 disposed on each interior of the lateral walls 208 is a coil, 224 for supplying time-varying magnetic fields. The lateral walls serve as supports to maintain the coils in a Helmholtz disposition. Figure 21 shows a schematic representation of the electromagnetic flux generated by the opposed Hemholtz coils 224. Referring to Figure 24, an electric current is supplied S from an AC power source (not shown) through power lines 230, 232 and into a transformer 234 and a rectifier bridge 236. To reduce heating of the coils by the current, a capacitor 238, and resistors 240 are used to reduce the effective current to the magnetic coils 224. A fan is used to cool the resistors. The manner and details for supplying electric current to the coils are well known in the art, and are not per se critical in this invention.
A slight variation of this embodiment is shown in Figure 23. In this embodiment, similar equipment is used, but the housing 200 is turned upside down and fixed to the sides of a narrow bed 245 made of non-magnetic material. The magnetic flux produced by the coils now runs perpendicular to the axis of the body 204. The timer and control mechanism 214 and 216 may be easily located at the side of the bed.
Another embodiment of the apparatus of this invention is illusuated in Figures 25 and 26.
The apparatus may be in the general form of a saddle 280. Referring to Figure 28, the saddle may be placed on a limb or a body part 282 to expose a patient to the homogeneous electromagnetic field in accordance with this invention. The apparatus may be fabricated from wood, plastic or other non-magnetic material to prevent interference with the application of an electromagnetic field to a patient's body part. As shown in Figures 25 and 26, the saddle is connected through electric cables 288 to the control unit 290 which contains a timer 292 and a control mechanism 294, both of which are connected to an electronic panel (not shown) for varying and controlling the intensity and duration of the electromagnetic field(s).
As shown in Figure 26 disposed on the. interior of the saddle walls are the coils 298 for supplying the time-varying magnetic field. Referring to Figure 24, the same circuit as used in the previous embodiment, Figures 19 to 23, can be used to deliver current to the coils 298 of the current embodiment illustrated in Figures 25 to 28. An electric current is supplied from an AC power source (not shown) through power lines 230, 232 and into the transformer 234 and the rectifier bridge 236.
To prevent heating of the coils by the current, a capacitor 238, and resistors 240 are used to reduce the effective current to the magnetic coils 298 and a fan is used to cool the resistors. The manner and details for supplying electric current to the coils are well known in the art, and are not per se critical in this invention.
There are two additional ways in which the electromagnetic fields of this invention may be generated. One is by modulating a continuous 27.12 MHz waves that transport electrical and magnetic energy through space (transporting waves) at the same frequencies of the present invention (i.e. an antenna to focus the electromagnetic fields of the present invention in any direction), and the other by modulating to the same frequencies of the present invention the electromagnetic fields of high intensity and frequency produced by a Tesla coil, (transporting waves).
The electromagnetic fields of this last design travel through space so a patient lying in bed or seated to a nearby source may be treated without seeing the apparatus.
In order to treat a patient afflicted with skin lesions or internal wounds in accordance with the method of this invention, the patient's limb (e.g. a hand or part of an arm) may be simply inserted through the opening 104, and partly extended through the passageway 105. The power source is then turned on to supply an electric current to the solenoid coil 119. The lines of flux produced by the magnetic fields generated within the space 107 are shown in Figure 3, and are seen to comprise variable as well as static magnetic flux lines. It has been found that the treatment is most effective when the electromagnetic field is applied at extremely low frequencies of more thin nne Hertz to less than about 300 Hz. The frequencies spectral content of the time-varying magnetic field
A slight variation of this embodiment is shown in Figure 23.

Another embodiment of the apparatus of this invention is illusuated in Figures 25 and 26.
The apparatus may be in the general form of a saddle 280. Referring to Figure 28, the saddle may be placed on a limb or a body part 282 to expose a patient to the homogeneous electromagnetic field in accordance with this invention. The apparatus may be fabricated from wood, plastic or other non-magnetic material to prevent interference with the application of an electromagnetic field to a patient's body part.

As shown in Figure 26 disposed on the. interior of the saddle walls are the coils 298 for supplying the time-varying magnetic field. Referring to Figure 24, the same circuit as used in the previous embodiment, Figures 19 to 23, can be used to deliver current to the coils 298 of the current embodiment illustrated in Figures 25 to 28.

It has been found that the treatment is most effective when the electromagnetic field is applied at extremely low frequencies of more thin nne Hertz to less than about 300 Hz. The frequencies spectral content of the time-varying magnetic field
13 are higher around approximately 120 Hz and its harmonics. See, for example Figure 5. These frequencies have a static magnetic field component with an intensity of about 0.3 to about 0.8 mT
root mean square (rms) and these EMFs can be used alone or in combination with a homogeneous static magnetic field of about 40 to about 80 mT (about 400 to about 800 Gauss). Thus, there are S two static magnetic fields: one is generated jointly with the time-varying magnetic field and preferably has a low magnetic flux density of a few microteslas to a maximum of about 0.3 to about 0.8 mT (rms) and the second has a higher density and is provided by the permanent magnets with a magnetic flux density of about 40 to about 80 mT, which is equivalent to about 400 to about 800 Gauss. The relationship between the instantaneous current supplied by the electric circuit to the magnetic coils as a function of time are shown as a series of waves in the forms shown in Figure 4.
As previously indicated, the application of time-varying magnetic fields with frequencies of a few Hertz (more than one) to less than about 300 Hz and static magnetic field components having an intensity of about 0.3 to about 0.8 mT used alone or with the simultaneous application of an homogeneous static magnetic field of about 40 to 80 mT or about 400 to about 800 Gauss, constitutes 1 S an essential (critical) feature of the method of this invention.
The wound healing effects of the present method and apparatus which were observed in patients are obtained by applying the time-varying electromagnetic fields described in this patent, either alone or in combination with static electromagnetic fields. Generally, however, each component separately and their combination evidence different degrees of effect on the proliferation of peripheral blood mononuclear cells (PBMCs). This may be seen clearly in Figure 29 accompanying this patent, showing the different degree of effects on cell proliferation evidenced by different types of magnetic fields when applied to PBMCs obtained from normal subjects (the 100%
cell proliferation control are PBMCs stimulated to proliferate with phytohaemaglutinin without the presence of any of the magnetic fields (EMFs) of this invention). The application of a combination of static and time-varying fields produced 11.1 % increase of PBMCs proliferation (P < 0.001 Student "T" test), the application of a time-varying magnetic field alone produced 67 % reduction of PBMCs proliferation (P < 0.001 Student "T" test), and the application of a static magnetic field alone had not significant effect on PBMCs proliferation.
For maximum benefit from the treatment, the magnetic fields are preferably applied to the patient's limb for about several minutes to about eight hours. The preferred exposure time was calculated so that a blood volume equivalent to the patient's entire blood volume is exposed to the magnetic field at least once. The exposure frequency may be varied from a maximum of about 30 minutes to about seven hours a day, to a minimum of about 30 minutes a week, depending on the observed lesion repair and wound healing observed.
The effect of EMFs in accordance with the present invention applied on isolated peripheral blood mononuclear cells (PBMCs) to modulate their proliferation patterns, their systemic effects in vivo and the application of external time-varying magnetic fields alone or in combination with static variable magnetic field for treatment of patients with chronic skin ulcers, chronic wounds, viable but underperfused myocardium, bone fractures and partial denervation is illustrated in the following examples.
The following examples illustrate the effectiveness of the method of this invention. These examples, however, are merely illustrative of the invention and are not to be construed so as to limit the scope thereof.

EXAMPLES
IN VITRO EFFECT
14 The following experiments show the effect of electromagnetic fields (EMFs), applied in accordance with the present invention, on the peripheral blood mononuclear cells (PBMCs).
Example 1: In Vitro Effects of Different Electromagnetic Fields on PBMC Proliferation Peripheral blood mononuclear cells (PBMCs) were obtained by venous puncture and fractionated on a ficoll gradient. The fraction containing PBMCs was washed 3 times and resuspended in phosphate buffered saline to a final concentration of 5 x 106 cells/ml. PBMCs aliquots 0.2 ml aliquots of 5 x 106 cells/ml, plus 1~ m/ml of phytohemaglutinin were placed in Eppendorf tubes. Four subsets were formed (three tubes per subset). The first subset was shielded from the magnetic fields. Subset 2 was exposed to the combination of time-varying electromagnetic fields and static magnetic fields in accordance with this invention Subset 3 was exposed only to the time-varying electromagnetic fields in accordance with this invention, and Subset 4 was exposed only to the static magnetic field in accordance with this invention. Four subsets were prepared without phytohemaglutinin (controls) and placed under the same experimental conditions.
All tubes were incubated at 37 °C in a COZ humidifier incubator (Forma Scientific Mod 3325 Dual -Chamber C02-water jacketed incubator). After an incubation period of 58 hours 1 ~.Ci of3H-thymidine (5-6 ~.Ci/mM final concentration) was added to all tubes and incubated for an additional 14 hours. All tubes were harvested at 72 hours and washed through glass fiber filter paper with a cell harvester, (Skraton, Tranby, Norway). 'H-thymidine incorporation was determined using a liquid scintillator counter (Beckmann Mod LS 6000 SE). The mean number of counts per minute was obtained by triplicate in each sample. Cell viability was always greater than 90% determined on the basis of trypan blue exclusion. Figure 27 accompanying this patent shows the magnetic fields effects on PBMCs obtained from normal subjects.
The combined static and time-varying electromagnetic fields produced an 11 %
increase in PBMCs proliferation (P < 0.001 Student "T" test). Time-varying electromagnetic fields alone produced about 67% reduction in cell proliferation (P < 0.001 Student "T"
test). Static magnetic fields have no effect on PBMCs proliferation. Therefore, the in vitro experiments demonstrate an effect of the magnetic fields on isolated PBMCs, which is different for each type of magnetic field or its combination.
IN VIVO EFFECT & SAFETY STUDY
Example 2: Effect of EMFs on Body Wounds (Safety and Tolerance Study) Since electromagnetic fields cross biological tissues, they also produce in vivo effects on circulating PBMCs. The in vivo effects of the time varying electromagnetic fields of this invention, 3 S alone or combined with the static magnetic fields, are observed in chronic skin wounds even after only about thirty minutes to one hour of exposing a body part situated far from the lesion site to the EMFs of this invention. In this period of time, it is common to observe the drying of a lesion and a reduction of its diameter.
The magnetic fields generated by the apparatus described in this patent are below the exposure limits recommended as safe by the World Health Organization (WHO).
However, due the fact that this is a pioneering procedure, the following study was performed to illustrate the safety of the external application of magnetic fields of this invention to humans. After submitting a letter of voluntary consent to participate in the magnetic field protocol, each patient was subjected to a complete clinical history, physical examination, blood chemistry, cell blood count, and urine analysis before magnetic field exposure was applied. Before, during and after exposure to an electromagnetic field, an electrocardiogram was performed and the blood pressure measured.
Three groups of volunteers were formed. The first group was exposed to the electromagnetic forces (EMFs) for 30 minutes a day, the second group for 30 minutes twice a week, and the third group for 30 minutes once a week. These three cohorts were followed for one year without presenting negative side effects.
In the last 5 years, more than 100 patients have been exposed one to seven hours a day one 5 to seven times a week to external magnetic fields in accordance with the method of this invention.
During the course of these treatments, no adverse or negative side effects were observed in any of these patients during or after the period of exposure to EMFs. The application of EMFs by the method and apparatus of this invention showed no effects on their electrocardiograms even in patients who had heart disease. Nor did such treatment have any adverse effects on the patient's motor and 10 sensory nerve function or conduction.
CLINICAL TRIALS
The following are clinical trials evidencing the efficacy of the treatment of the invention as applied to the limb of patients with histories of chronic wounds, which were previously unresponsive to other therapeutic treatments.

Food and Drug Administration (Phase I Study) was presented to the Juarez Hospital Instir.~tional Review Board/Ethics Committee and was approved September 24, 1995. Standard operating procedures were followed for monitoring the clinical trial. A total of 42 patients were studied.
The following clinical trials demonstrate the efficacy of the treatment of the invention as applied to the limb of patients with histories of chronic wounds, which were previously unresponsive to other therapeutic treatments and to patients with bone fractures.
Electromagnetic stimulation as defined below was applied in the arm two to three hours a day, several times a week, or a period of two to eight months. All exposed tissues of the arm were considered under the combined effect of the static andlor time variable magnetic fields. The intensity of the induced variable electric fields in each segment of the arm varied with the radius according to Faraday's law.
Twenty five patients were admitted for treatment of chronic leg ulcers. The complete case record for each patient contains a signed voluntary consent form. Their clinical histories include definition of venous and arterial diseases, presence of other underlying diseases, ulcer history and treatments used. Only lesions that remained unhealed at the time of examination were followed up.
Each ulcer was described and documented by photographs, its size and approximate area calculated (length x width). When more than one ulcer existed, an approximate total ulcer area was determined.
Laboratory tests include blood chemistry, hematological examinations, electrocardiogram and other diagnostic tests. The peripheral circulation was evaluated by doppler-color ultrasonography, arteriography, venography and pletismography. The follow-up records include a periodic photographic registration of chronic leg ulcer history, a weekly clinical commentary and a report of physical examination.

Before electromagnetic therapy was given to the patient, she required local anesthesia while her ulcer was cleaned. The electromagnetic stimulation was applied to her arm 1 hour/day, 5 days/week for a period of over 2 months, during which time her ulcer was cleaned daily. No other treatment was administered at this time.
After 4 weeks of treatment the pain and edema disappeared, anesthesia was no longer needed to clean the ulcer, and the patient became fully mobile. Abundant granulation tissue appeared in the ulcer bottom and the ulcer was completely healed after 2 months of the treatment.
Example 21: Middle Aged Male with Uncontrolled Arterial Hypertension & Deep Vein Thrombosis Patient No. 22 is a 54 year old man, afflicted with uncontrolled arterial hypertension and deep vein thrombosis which had chronic leg ulcers totaling 20 cmz for over 7 years. The ulcerated area was accompanied by pain, edema, and limited mobility. During this time, he received medical treatment, including anti-hypertensive therapy, but it was ineffective in improving his condition.
After 3 months of electromagnetic treatment, the medial malleolus ulcer healed and the ulcer in the front part of her leg healed in seven months. During this time her depressive mood improved.
Example 20: Middle Aged Female with Vascular Necrosis Patient No. 21 is a 45 year old woman afflicted with vascular necrosis of the right leg resulting from receiving a silicon implant. Reconstructive surgery saved her leg from amputation.
Two years after, the use of a tight prosthesis lead to arterial occlusion in the posterior-medial area other leg, resulting in a very painful 23 cm2 ulcer that lasted for over 5 months. Pain and edema accompanied the ulcer, and she had limited mobility. During that time she received medical treatment, but it was ineffective in relieving her condition.

Electromagnetic stimulation in accordance with the present method was then applied on one of her arms for 3 hours/day, 3 days/week for a period of over 4 1/2 months, during which time she received a continuation of her anti-hypertensive treatment. During the course of electromagnetic therapy the patient developed a third lesion which was produced by trauma.
After one week of treatment, the pain, edema, and the three-month-old leg ulcer disappeared. The lesion induced by subsequent trauma healed after 6 weeks of electromagnetic treatment. The patient was followed for an additional year and the ulcers remained healed.
Example 23: Old Female with Generalized Atherosclerosis Patient No. 24 is an 85 year old woman afflicted with generalized atherosclerosis and a chronic leg ulcer 1.2 cm2 for over one year. During that time she received the recommended medical treatment but it was ineffective in relieving her condition.
Electromagnetic stimulation in accordance with the present method was applied to one of her arms 2 hours/day, 5 days/week for a period of over 2 months. After two weeks of treatment the pain and edema disappeared. These changes were followed by a reactivation of the inflammatory reaction around the ulcer with an exuberant increase of granulation tissue that cover the ulcer bottom reflecting enhanced angiogenesis. In three months the ulcerated area was reduced by more than 70 % .

Diabetes Mellitus & Hypercholesterolemia Patient No. 25 is a 24 year old man afflicted with uncontrolled Type I
diabetes mellitus and hypercholesterolemia, afflicted with a three month old plantar ulcer on his left foot. The patient received local surgical and medical treatments that were ineffective in relieving his condition. The electromagnetic stimulation was applied to one of his arms 2 hours/day, 5 days/week for a period of over 2 months. After three weeks of treatment the deep ulcer base was at the level of the dermis.
The ulcer healed completely in four weeks. The patient was followed for an additional four months remaining asymptomatic.
IH. PRESSURE ULCERS (DECUBITUS ULCERS) This group includes patients whose underlying afflictions were, in addition to the pressure ulcers, paraplegia, deep vein thrombosis and obesity, among others. Pain, edema and infection accompanied the pressure ulcers.
Example 25: Middle Aged Incontinent, Paraplegic Female with Leg Wounds Patient No. 26 is a 64 year old, paraplegic and incontinent woman who had 2 wounds. The 24 cmz wound located on her left thigh had been caused by an attempt to surgically repair an electric blanket burn and was 6 months old. The second wound was a 4-month-old, stage 5 Yarkony-Kirk
22 classification decubitus sacrum ulcer. During that time, she received systemic antibiotic treatment and three attempts were made to surgically repair her wounds. Those treatments were ineffective in improving her condition. Electromagnetic stimulation was then applied on one of her arms for 6 hours/day, 7 days/weeks for a period of over 8 1/2 months. The patient received nurse care for 24 hours/day and continued to receive systemic antibiotic treatment. No other additional wound treatment was administered at this time.
After 6 weeks of electromagnetic treatment the thigh wound healed, the decubitus ulcer infection was controlled, and wound retraction and epithelialization continued to heal the wound.
After 13 weeks of electromagnetic treatment the abundant granulation and epithelial tissues were removed and the wound was surgically closed after leaving a surgical drainage.
After 3 further weeks of electromagnetic treatment, the surgical wound was healed and an ulcerated area was formed at the surgical drainage. An autologous skin graft placed on the ulcer site was eventually lost. The decubitus ulcer healed completely after three additional months of electromagnetic therapy.
Example 26: Old Female with Pressure Ulcer & Deep Vein Thrombosis Patient No. 27 is an obese 90 year old woman who had an 18 month old, 60 cm2 painful, edematous, bleeding, friable, purple, deep pressure ulcer on her left ischial tuberosity caused by her sitting in the same position for 8 to 12 hours/day while being afflicted with deep vein thrombosis.
Pain and edema accompanied the ulcer. During that time, the patient received medical treatment including local wound cleaning, but the treatment was ineffective in improving her condition.
Electromagnetic stimulation was then applied to one of her arms for 2 hours/day, 7 days/week for a period of over 5 months. She continued to receive local wound cleaning, but no additional treatment was given to her at this time.
After 2 weeks of electromagnetic treatment the pain and edema disappeared, except for a 1 x 10 mm open skin area which did not heal because of the constant pressure from sitting. During the course of treatment, her skin resistance increased. The color of the skin was pink in the morning and bright red after 8 to 12 hours of sitting. After 4 months of treatment, the ulcer was completely healed and the skin returned to normal.
IV. CHRONIC WOUNDS
This group included patients whose underlying afflictions were, in addition to the chronic wounds, peripheral arterial disease, intense stress and peritonitis, among others. Pain, edema and infection accompanied the chronic wounds.
Example 27: Old Male with Infected Surgical Wound Patient No. 28 is a 78 year old man who had a 126 cm2 infected surgical wound after a long 3 S and complicated abdominal surgery.
Electromagnetic stimulation was applied to one of his arms 1 hours/day for 3 weeks. After 2 weeks of treatment the infection disappeared, and the wound was surgically closed because of granulation tissue and wound healing were under optimal conditions for this procedure.
Example 28: Old Man with Unhealed Surgical Wounds Patient No. 29 is a 73 year old man with lower limb arterial disease associated with smoking, diabetes and generalized atherosclerosis. Chronic lower-limb ischemia had been present for years. Critical leg ischemia was evident in the last year and the patient was subjected to surgical re-vascularization. However, 3-1/2 months after the operation, the surgical wounds located in his left thigh and leg were not healed and the knee surgical wound remained an open 30 cm2 wour.4.
After 6 weeks of electromagnetic treatment the thigh wound healed, the decubitus ulcer infection was controlled, and wound retraction and epithelialization continued to heal the wound.
After 13 weeks of electromagnetic treatment the abundant granulation and epithelial tissues were removed and the wound was surgically closed after leaving a surgical drainage.
After 3 further weeks of electromagnetic treatment, the surgical wound was healed and an ulcerated area was formed at the surgical drainage.

Chronic lower-limb ischemia had been present for years. Critical leg ischemia was evident in the last year and the patient was subjected to surgical re-vascularization. However, 3-1/2 months after the operation, the surgical wounds located in his left thigh and leg were not healed and the knee surgical wound remained an open 30 cm2 wour.4.
23 Electromagnetic stimulation in accordance with this invention was then applied to one of his arms 2 hours/day 3 days/week for a period of five months. No additional treatment was administered to him.
After 4 weeks of electromagnetic treatment the thigh and leg wounds healed and wound retraction and epithelialization continued to heal the knee wound, reducing the wound area to about 97% in 5 months. The wound was completely healed in one additional month.
Example 29: Middle Aged Female with an Unhealed Ulcer Patient No. 30 is a 65 year old woman with lower limb arterial disease associated with smoking. As a consequence of a trauma, a small bruise developed into a 2.6 cmz infected, very painful ulcer, in two weeks causing reduced mobility. This wound was resistant to antibiotic treatment.
Electromagnetic stimulation in accordance with this invention was then applied to one of her arms 2 hours/day, 5 days/week in addition to a new antibiotic treatment. After two weeks the infection was controlled, edema and pain were drastically reduced and mobility became almost normal. The previously unhealed wound displayed abundant granulation tissue on the ulcer bottom.
A week later the patient was asymptomatic and ulcer healed in less than one month since the beginning of EMFs treatment.
Example 30: Middle Age Male with an Infected Shoulder Wound Patient No. 31 is a 57 year old man under intense stress who by scratching an old scar developed a 3 cm3 very painful abscess in his left shoulder in two weeks. The lesion was controlled with antibiotics but two weeks later pain, edema, immobility and a 3 cmz open wound were still present.
Electromagnetic stimulation in accordance with this invention was then applied to one of his arms 2 hours/day, 5 days/week. Three weeks later, pain, edema and immobility disappeared and the wound was reduced by more than 70% . The ulcer healed completely two weeks later.
V. DILATED ISCHEMIC CARDIOMYOPATHY
This group includes patients with viable but underperfused myocardium, who were not candidates for coronary revascularization.
Atherosclerosis is a generalized disease responsible for occlusive arterial disease such as lower-limb arterial disease (chronic arterial leg ulcers), myocardial infarction and stroke. The etiological factors (arterial hypertension, high serum cholesterol, smoking, stress, diabetes mellitus) are similar, as are preventive measurements (eliminate or control the etiological factors), and some treatments (angioplasty or by-pass when indicated). The enhancement of the body's natural process of collateral blood vessel growth is a novel approach. Therapeutic angiogenesis has been attempted using angiogenic growth factors. Acid and basic fibroblast growth factors have been successfully tested in animal models but positive clinical results have not been reported in clinical trials. Vascular endothelial growth factor (VEGF) recombinant protein has been successfully tested in patients with heart infarction that were not ideal candidates for coronary revascularization and intramuscular injection of naked plasmid DNA encoding the 165 isoform of VEGF has been successfully tested in patients with critical limb ischemia.
Example 31: Young Male with Sequels of Anteroseptal Acute Myocardial Infarction Patient No. 32 is a 40 year old man with sequels of anteroseptal acute myocardial infarction.
The patient was evaluated by clinical examination, blood tests, chest X-Ray, electrocardiogram, stress test, echocardiogram, coronary angiography, and cardiac ventriculography. The observed lesions include anteroseptal myocardial infarction with extensive anterior and lateral sub-epicardic
After 4 weeks of electromagnetic treatment the thigh and leg wounds healed and wound retraction and epithelialization continued to heal the knee wound, reducing the wound area to about 97% in 5 months. The wound was completely healed in one additional month.

Example 31: Young Male with Sequels of Anteroseptal Acute Myocardial Infarction Patient No. 32 is a 40 year old man with sequels of anteroseptal acute myocardial infarction.
The patient was evaluated by clinical examination, blood tests, chest X-Ray, electrocardiogram, stress test, echocardiogram, coronary angiography, and cardiac ventriculography. The observed lesions include anteroseptal myocardial infarction with extensive anterior and lateral sub-epicardic
24 ischemia and left bundle anterior hemi- branch block. 90% stenosis in middle third of left anterior descending coronary artery with a severe stenosis of first diagonal artery at its origin, slow TIMI 2 flow, anterior, apical, inferior and septal akinesis. Ejection fraction 20 % .
Patient was classified as Functional Class III of the New York Heart Association (NYHA) being not candidate for coronary revascularization. Patient remained on isorbide 10 mg 3/day, aspirin 150 mg/day and rest during four additional months without showing any improvement. Electromagnetic force (EMFs) was then applied to one of his arms 2 hours/day, 3 days/week for a period of one month while continuing with the same medical treatment as before.
After one month of EMFs treatment, patient improvement was very fast even in the presence of bad evolution of the left descending coronary artery lesion that changed from 90%
stenosis to occlusion. Clinical evaluation and stress test classified the patient in Functional Class I of the New York Heart Association (NYHA), instead of the Class III he had before.
Anterior, apical, inferior and septal akinesis diagnosed by ventriculograin and echocardiogram improved to hypokinesis. Collateral circulation and contractility of hybernating myocardium improved.
1 S These changes may not be explained by the medical treatment he received during four months after AMI and previously to be exposed to EMFs. During all this period the patient remained in Functional Class III (NYHA). The most plausible explanation for the patient's better clinical condition in only one month after EMFs exposure, Functional Class I (NYHA), is enhanced angiogenesis and vasculogenesis in viable but underperfused myocardium induced by the EMFs activated peripheral blood mononuclear cells.
example 32: Obese Woman with Arterial Hypertension & Sequels of Three Month Old Acute Myocardial Infarction Patient 33 is a 54 year old obese woman afflicted with arterial hypertension and sequels of a three month old Acute Myocardial Infarction (AMI). Patient evaluation included clinical examination, blood tests, chest X-Ray, electrocardiogram, stress test, echocardiogram, coronary angiography, and cardiac ventriculography. Lesions included Arterial Hypertension, elevated blood values of Glucose, Uric Acid, Triglycerides and Cholesterol. Anteroseptal and lateral subendocardic necrosis. Extensive anterior sub-epicardic ischemia. Right atrium enlargement.
Coronary angiogram. reported occlusion of left descending coronary artery at its origin and 80% stenosis of circumflex. Patient was treated with Metoprolol 50 mg./12 Hs., Isorbide 10 mg./12 Hs., Pravacol 20 mg./24 Hs. Norvas 2.5 mg./24 Hs. and ASA 100 mg./24 Hs. Three months later arterial hypertension and blood tests were within normal limits but the cardiovascular symptomatology deteriorated, from Functional Class II New York Heart Association (NYHA) to Functional Class III
(NYHA). An stress test was attempted but had to be suspended at the beginning of the test by fatigue, hypertension and pain. Functional Class III (NYHA).
Electromagnetic stimulation was then applied to one of her arms 2 hours/day, 4 days/week for a period of five months while continuing with her previous treatment.
After one month of EMFs treatment, patient evaluation changed from Functional Class III
(NYHA) to Functional Class I (NYHA) and collateral circulation and contractility of hibernating myocardium improved. These changes occur in the presence of more severe lesions than the ones observed in her previous coronary angiogram including additional occlusion of the right coronary artery at its middle third, 90% stenosis of the first diagonal artery and left ventricle diastolic final pressure of 15 mm Hg.
These changes in only one month after EMFs may not be explained by the medical treatment she received during nine months after AMI and previously to be exposed to EMFs. During all this period the patient evolved from Functional Class II (NYHA) to functional class III (NYHA~. The most plausible explanation for the patient's better clinical condition, Functional Class I (N YHA), are enhanced angiogenesis and vasculogenesis in viable but underperfused myocardium induced by the EMFs activated peripheral blood mononuclear cells.
VI. ANKLE FRACTURES
This group included patients with no other underlying affliction. This orthopaedic problem S was selected to evaluate the benefits of the EMFs of this invention in reducing pain and edema in an acute problem as well as to observe if it could accelerate the healing process of a different type of internal wound, i.e. a bone fracture.
Example 33: Eight Patients with Ankle Fractures Type Weber A or B
This example presents information on a group of eight patients (patients 34 to 41). The 10 patients are two women and six men 19 to 65 years old, afflicted with uni or bi-malleolar ankle fractures type Weber A or B. All fractures were accompanied with intense pain, and edema. All fractures were treated with internal fixation. Compression of fracture surfaces was obtained with lag screws with or without semitubular compression plates. Surgical repair of the deltoid ligament was done when indicated. Sterile dressings were applied to the wounds and then a plaster splint to hold 15 the foot in neutral position.
Electromagnetic stimulation was then applied to each patient on either arm 2 hours/day, 2-3 days/week for 10 sessions beginning the next day after surgery. Leg was maintained elevated and pain was controlled with Dipirone 500 mg 3/day.
In all patients, pain was reduced from 10 to 3-4 days. Edema from 10 to 5-6 days and bone 20 -union-was observed in-four weeks instead of six, at that point patients were allowed full-weight bearing.

VII. SPINAL MUSCULAR ATROPIES
This patient was selected as an example of nerve regeneration in a disease with no present treatment. In partial denervation, the axon and the nerve terminal innervating a muscle fiber
25 degenerates. Healthy denervated tissue responds by releasing cytokines that induce the terminal Schwann cells on the denervated muscle fiber to grow processes that reach the nerve terminal of a neighboring innervated muscle fiber. Then the Schwann cell process induce a nerve sprout in the normal nerve terminal that grows along the Schwann cell process towards the denervated endplate until reinnervation of the denervated endplate is completed. At early stages of certain types of spinal muscular atrophies when a motor neuron of the spinal cord dies, cytokine signaling language stimulated by EMF's activated PBMCs could trigger these events in neighboring healthy axons not affected by the disease producing reinervation of the denervated muscle fibers.
Exam In a 34: Young Boy with Spinal Muscular Atrophy Patient 42 is a 4 year old boy with Spinal Muscular Atrophy. Being the second boy of a normal twin pregnancy and delivery, their parents had the benefit to compare one twin to the other.
Their recollection suggests that early development was delayed. He started walking at 15 months but his gait appeared abnormal and since age 2 he has been unable to run or hop, has difficulty walking up one or two steps, tends to fall frequently and needs help getting back on his feet. At physical examination weakness of all muscle groups was noticeable but more so in the shoulder and pelvic girdles. These findings together with the subtle fasciculations of the tongue, electromyography, magnetic resonance imaging and left quadriceps biopsy support the diagnosis of Spinal Muscular Atrophy. During the last year, diets, rehabilitation therapy and the use of stabilizing artroses have been ineffective in improving his condition.

These findings together with the subtle fasciculations of the tongue, electromyography, magnetic resonance imaging and left quadriceps biopsy support the diagnosis of Spinal Muscular Atrophy. During the last year, diets, rehabilitation therapy and the use of stabilizing artroses have been ineffective in improving his condition.
After signing a voluntary consent form, electromagnetic stimulation was then applied to nne of his arms, 2 hours/day, 2 days/week for one month, however this was difficult to achieve because
26 of his age. Therefore a new design with Helmholtz coils was used to expose part of the body while the child was sleeping. This modality of electromagnetic stimulation was applied 2 hours/day, 5 days/week for a period of two years.
Periodic examinations by the inventor, the pediatrician, the neurologist, the rehabilitation specialist, notes of the mother and teacher, and videotapes, were used to follow his evolution. After the first month his equilibrium was better, more confident to play with his brother, sister and peers at school. He started gaining weight, and at 4 months he was able to walk without falling and began to run and hop. At six months, an increase in muscular strength and mass of the shoulder and pelvic girdles was noticeable. One year after the initiation of treatment the child was able to rise from the floor without help. Two years after, his movements and development were almost normal.
CONCLUSIONS
The above examples show that the application of external, non-invasive electromagnetic fields (EMFs) in accordance with the method of this invention, either alone or combined with other medical and surgical treatments healed body lesions in patients who were previously unresponsive to conventional medical and surgical treatments alone, or improve the effects of these treatments.
Thus, from the foregoing detailed description of the invention, and the illustrative examples provided herein, it may be appreciated that the treatment offers a remarkably effective clinical means for improving a patient's health and well being without producing adverse or negative side effects.
This has been exemplified on patients with various diseases and conditions, such as a history of partial denervation, internal or external lesions such as wounds, areas with inadequate blood perfusion such as viable but underperfused myocardium and the like, burns and ulcers alone or where the patient is suffering from other disorders as well.
