BACKGROUND OF THE INVENTION

The present invention relates to a new and improved strap or treatment apparatus and a method of using the strap or treatment apparatus to treat a patient.
A known strap for use in treating a patient includes a layer of foam which is connected with a layer of fabric. When the strap is to be utilized to treat a patient, the layer of foam is placed in engagement with the skin of the patient and the strap is wrapped around a portion of the patient. Known straps which may be utilized for treating a patient are disclosed in U.S. Pat. Nos. 2,811,154 and 5,036,838.

SUMMARY OF THE INVENTION

The present invention relates to a new and improved strap and method of using the strap for treatment of a patient. Base and second end portions of the strap may be interconnected by a main portion of the strap. The base end portion of the strap may have opposite sides with surfaces which are formed of foam. The main portion of the strap may have a first side with a surface which is formed of foam and a second side with a surface which is formed of fabric. If desired, the surfaces formed of foam could be formed of a different material. A retainer may be connected with the second end portion of the strap to connect the second end portion of the strap with the main portion of the strap.
When the strap is to be utilized to treat a patient, a layer formed of foam disposed on the first side of the strap may be placed in engagement with skin on the body of the patient. The base end portion of the strap is retained against movement relative to the body of the patient by wrapping the strap around a portion of the body of the patient and positioning a portion of the layer formed of foam on the first side of the strap in engagement with foam disposed on the second side of the base end portion of the strap. The second end portion of the strap may be connected with a fabric layer which forms the second side of the strap.
If desired, a plurality of straps may be utilized in the treatment of the patient. At least some of these straps may have a layer of foam disposed on a first side of the strap and a layer of fabric disposed on a second side of the strap. The layers of foam on the first sides of the straps may be positioned in engagement with the skin of the patient and the straps may be interconnected. Interconnecting of the straps may be performed by engaging foam on the second side, that is the fabric side, of a strap with the layer of foam on the first side of a strap. A retainer which, for example, may be a hook and loop type fastener, may be provided to connect an end portion of one strap with a layer of fabric on another strap or with a layer of fabric on the one strap.
It is contemplated that a strap constructed in accordance with the present invention may be utilized during the treatment of many different portions of a patient's body. For example, the strap may be utilized in conjunction with treatment of an arm, hand, leg, foot, shoulder, or other portion of a patient's body. A single strap may be wrapped around one or more portions of a patient's body. Alternatively, a first strap may be wrapped around one portion of a patient's body and a second strap may be connected with the first strap and wrapped around another portion of a patient's body.
The strap may be utilized to apply force to deep fascia, such as myofascial tissue. Of course, the strap may also be used to apply force to superficial fascia. It is contemplated that one or more of the straps may be used to increase a patient's proprioception. The straps may also be utilized to effect shifting of a bone, such as a patella, in the body of a patient. The straps may be used to connect one or more treatment devices with a patient.

DESCRIPTION OF SPECIFIC PREFERRED EMBODIMENTS OF THE INVENTION

Strap Construction

A strap 10 for use in treating a patient is illustrated in FIGS. 1 and 2. The strap 10 includes a base end portion 12, a second or retainer end portion 14, and a main portion 16. The main portion 16 extends between the base end portion 12 and retainer end portion 14. The strap 10 has an outer side 20 (FIG. 1) and an inner side 22 (FIG. 2). The inner and outer sides 20 and 22 extend between opposite ends of the strap 10.
The main portion 16 of the strap 10 has an outer side surface 26 (FIG. 1) formed by a layer 28 of fabric (FIG. 3). An opposite or inner side surface 32 (FIG. 2) of the strap 10 is formed by a layer 34 of foam. In the embodiment of the invention illustrated in FIG. 3, the layer 34 of foam is bonded directly to the layer 28 of fabric. It is contemplated that the layer 28 of fabric and layer 34 of foam may be interconnected in a manner similar to that disclosed in U.S. Pat. No. 5,036,838. In the illustrated embodiment of the invention, the layer 28 of fabric and the layer 34 of foam are coextensive with each other. Thus, the layer of fabric and the layer of foam both extend through the base end portion 12, main portion 16, and retainer end portion 14 of the strap 10.
The layer 28 of fabric (FIG. 3) is an elasticized polymeric material. The layer 28 of fabric has a loop-type weave similar to the material which forms the loop portion of a hook and loop fastener and is commercially available under the trademark “Velcro”. The layer 28 of fabric has an outer side surface 26 which is relatively slippery. The surface 26 of the fabric layer 34 and the skin of a patient have a relatively low coefficient of static friction.
The loop weave of the elasticized fabric layer 28 enables it to be engaged by hook-type fasteners of the “Velcro” (trademark) type. Thus, the layer 28 of fabric has a loop pile which forms the outer side 20 of the strap 10. It is preferred to form the layer 28 of fabric with an elasticized construction so that the fabric can be stretched by pulling on the strap 10. However, if desired, the layer 28 of fabric could have a nonelasticized construction and could have a weave other than a loop weave.
The layer 34 (FIG. 3) of foam is connected directly to the layer 28 of fabric. The layer 34 of foam is formed with an open celled, elastomeric construction. The open celled elastomeric construction of the layer 34 of foam enables the layer to breath so that fluid can pass through the layer. The open celled construction of the layer of foam promotes patient comfort when the strap 10 is worn for a relatively long period of time.
The layer 34 of foam has a side surface 32 which has a relatively high adherence or grippiness compared to the surface 26 on the layer 28 of fabric. The surface 32 of the layer 34 of foam and the skin of a patient have a relatively large coefficient of static friction. The coefficient of static friction between the surface 32 and the layer 34 of foam and the skin of a patient is greater than the coefficient of static friction between the surface 26 of the layer of fabric 28 and the skin of a patient.
The layer 34 of foam is stretchable so that it can be stretched with the layer 28 of fabric. The elasticity of the layer 34 of foam is greater than the elasticity of the layer 28 of fabric. Thus, the modulus of elasticity of the layer 34 of foam is greater than the modulus of elasticity of the layer 28 of fabric.
The layer 34 of foam is an open celled foam of the urethane family and is stretchable in both the longitudinal and transverse directions to a greater extent than the layer 28 of fabric. This results in the layer 34 of open celled foam being supported by the layer 28 of fabric when the layer of fabric is in a stretched or non-stretched condition. It should be understood that the layer 34 of foam could be formed of any desired open celled or closed cell polymeric foam material. It is contemplated that the layer 34 could be formed of a polymeric material which is not a foam. The layer 34 could be formed of any material having a high coefficient of friction with skin.
One commercial source of material to form the strap 10 is Fabrifoam Products of Exton, Pa. Of course, other commercial sources of material for forming the strap 10 could be utilized if desired.
The layer 28 of fabric and the layer 34 of foam extend through the retainer end portion 14 of the strap 10 (FIGS. 2 and 4). A retainer 38 is provided at the retainer end portion 14 of the strap 10. The retainer 38 has a rectangular configuration (FIG. 2) and is fixedly connected with the layer 34 of foam and layer 28 of fabric by heat staking. Of course, the retainer 38 could be connected with the layer 34 of foam and the layer 28 of fabric by other methods if desired. For example, the retainer 38 could be bonded to the layer 34 of foam.
The retainer 38 has the same construction as the hook portion of a hook and loop fastener of the “Velcro” (trademark) type. Thus, the retainer 38 has an array of hooks 42 which are engagable with the loop-type fabric which forms the layer 28 of fabric. Although it is preferred to utilize a retainer 38 which is engagable with a layer 28 of fabric with a “Velcro” (trademark) hook and loop type fastening action, a different type of retainer could be utilized if desired. By forming the retainer 38 with the “Velcro” (trademark) hook type construction, the retainer 38 can be connected with the layer 28 of fabric at any location along the length of the layer of fabric. However, other types of retainers could be utilized if desired.
The base end portion 12 (FIG. 1) of the strap 10 is formed by doubling the layer 28 of fabric and the layer 34 of foam back on itself. This results in the base end portion 12 of the strap 10 having a double-layered construction illustrated in FIG. 5. Thus, the base end portion 12 has an upper (as viewed in FIG. 5) layer 48 and a lower layer 50 which are interconnected by a bend 52. The upper layer 48 is heat staked to the lower layer 50 to interconnect the upper and lower layers 48 and 50.
The overlapped construction of the base end portion 12 results in the layer 28 of fabric and the layer 34 of foam extending in a continuous manner from the main portion 16 of the strap 10 through the lower layer 50 of the base end portion 12, around the bend 52, and through the upper layer 48 of the base end portion 12. The layer 28 of fabric is integrally formed as one piece and extends throughout the entire extent of the strap 10. Similarly, the layer 34 of foam is integrally formed as one piece and extends throughout the entire extent of the strap 10.
It should be understood that the base end portion 12 could have a different construction. For example, the upper layer 48 could be formed by a separate rectangular segment formed of the same material of the main portion 16 of the strap 12. This separate rectangular segment of material may be heat staked to the lower layer 50 of the base end portion 12. Alternatively, the base end portion 12 could be formed with a single layer 28 of fabric with two separate layers of foam adhered to opposite sides of the single layer of fabric. Thus, a layer of foam could be adhered to the outer side surface 26 of the layer 28 of fabric throughout the extent of the base end portion 12 to provide a layer of foam which is separate from and on the opposite side of the strap from the layer 34 of foam.
Although a preferred construction for the strap 10 has been illustrated in FIGS. 1 through 5, it is contemplated that the strap 10 may have a different construction if desired. For example, rather than being formed by separate layers of foam and fabric, the strap 10 may be formed from a single layer of material. If desired, with such a construction, a separate base end portion 12 and retainer end portion 14 may be connected to the single layer of material. Alternatively, the strap 10 could be formed of multiple layers of fabric and/or multiple layers of foam. Although it is preferred to form the strap 10 with the layer 34 being an open celled urethane foam, the layer 34 could be formed of a substantially different material if desired.
The illustrated strap 10 has an outer side surface 26 which is slipperier than the inner side surface 32. This is because the outer side surface 26 is formed of a woven polymeric material while the inner side surface 32 is formed of a polymeric foam. It is contemplated that both the outer side surface 26 and the inner side surface 32 could be formed of one or more materials having substantially the same degree of roughness or gripping action.
In the illustrated embodiment of the strap 10, the only foam which is exposed on the outer side 20 of the strap 10 is on the base end portion 12 of the strap. It is contemplated that foam could be exposed at other locations on the outer side 20 of the strap 10. For example, a rectangular section of foam could be disposed on the outer side 20 of the strap 10 at a location midway between the base end portion 12 and the retainer end portion 14. This additional section of foam could be secured to the outer side 20 of the strap 10 by heat staking or by bonding directly to the outer side surface 26 of the layer 28 of fabric.
Use of Strap
The strap 10 of FIGS. 1-5 may be used in many different ways in association with many different portions of a patient's body. The strap 10 may be utilized to apply only compressive forces to tissue in the patient's body. Alternatively, the strap 10 may be used to provide a combination of compressive and tension forces in tissue in the patient's body. The combination of compressive and tension forces is particularly advantageous when it is desired to effect movement of superficial and/or deep fascia relative to other tissue in a patient's body. The combination of compressive and tension forces applied by a strap 10 can be utilized to effect shifting movement of one bone in a patient's body relative to another bone.
It is contemplated that the strap 10 may be utilized in many different types of patient treatments. It is believed that the strap 10 may be used during active, causal, expectant, palliative, preventive, supportive, and/or symptomatic treatments of a patient. For example, the strap 10 may be used to apply force to body tissue to alter the action of muscles and/or to change the relationship between adjacent body tissues at many different locations in a patient's body.
When the strap 10 is wound in a circular loop around a portion of a patient's body, the strap 10 may be utilized to provide a pure compressive force against tissue of the patient's body. However, when the strap 10 is wound in a spiral around a portion of the patient's body, the strap 10 exerts both compressive and tension forces against tissue of the patient's body. The magnitude of the compressive and tension forces may be varied by varying the tension in the strap 10. Thus, one turn of a spiral wrapping of the strap 10 around a portion of a patient's body may be formed with a first tension in the strap and a second turn of the spiral wrapping may be formed with a tension which is greater than the first tension to increase shear forces applied to body tissue.
When the strap 10 (FIG. 6) is to be wrapped around a patient's body in such a manner as to provide both tension and compressive forces on tissue of the patient's body, the strap 10 is oriented with the layer 34 of foam facing toward skin 60 on a portion 62 (FIG. 6) of the patient's body. The layer 28 of fabric faces outward away from the skin 60.
When the strap 10 is to be wrapped around the portion 62 of the patient's body, the base end portion 12 is positioned in engagement with the skin 60 of the patient. The upper layer 48 of the base end portion 12 faces away from the skin 60 (FIG. 6) on the portion 62 of the patient's body. Similarly, the lower layer 50 (FIG. 5) of the base end portion 12 is positioned in engagement with the skin 60 (FIG. 6) on the portion 62 of the patient's body. The inner surface 32 on the layer 34 of foam grips the skin 60 on the patient's body to retain the base end portion 12 against undesired movement relative to the patient's body. The base end portion 12 may be positioned in engagement with the patient's body by the patient or by medical personnel.
Regardless of whether the strap 10 is being positioned by the patient or another person, the base end portion 12 of the strap is manually pressed against the skin 60 to position the base end portion 12 of the strap relative to the portion 62 of the patient's body. The main portion 16 of the strap 10 is then wrapped in a loop around the patient's body, in the manner illustrated schematically in FIG. 6. As the main portion 16 of the strap 10 is wrapped in a loop around the patient's body, the layer 28 of fabric faces outward while the layer 34 of foam faces inward. This results in the layer 34 of foam being moved into engagement with the foam on the upper layer 48 of the base end section 12 (FIG. 7).
As the main portion 16 of the strap 10 moves into engagement with the base end portion 12 of the strap, the main portion 16 is tensioned and the base end portion 12 is pressed against the skin 60 of the patient. As the lower layer (FIG. 5) of the base end portion 12 is pressed against the skin 60 of the patient, the layer 34 of foam grips the skin 60 of the patient. As the layer 34 of foam on the main portion 16 of the strap 10 is pressed against the upper layer 48 of the base end portion, the layer 34 of foam on the main portion 16 of the strap 10 engages and firmly grips the layer 34 of foam on the upper layer 48 of the base end portion 12.
There is a relatively large coefficient of static friction between the inner side surface 32 (FIG. 3) of the layer 34 of foam on the main portion 16 of the strap 10 and the surface of the foam on the upper layer 48 (FIG. 5) of the base end portion 12 of the strap. This relatively large coefficient of static friction results in the main portion 16 of the strap 10 and the base end portion 12 of the strap being securely interconnected by a friction connection.
As the main portion 16 of the strap 10 is wrapped in loops around the portion 62 of the patient's body, the base end portion 12 of the strap 10 is pressed firmly against the skin of the patient. There is a relatively large coefficient of static friction between the inner side surface 32 on the layer 50 (FIG. 5) of the base end portion 12 and the skin 60 of the patient. This results in the base end portion 12 of the strap 10 being securely gripped between the portion 62 (FIG. 7) of the body of the patient and the main portion 16 of the strap 10. This results in the base end portion 12 being anchored against movement relative to the skin 60.
The friction connection established between the foam on the inside of the main portion 16 of the strap 10 and the foam on the outside of the base end portion 12 of the strap forms the first turn of the strap into a loop around the portion 62 of the patient. By tensioning the main portion 16 of the strap 10, the loop can be pulled toward the right, as viewed in FIG. 7. Pulling the loop around the portion 62 of the patient's body applies tension forces to the skin 62 of the patient. These tension forces are transmitted to body tissue beneath the skin of the patient. The rightward (as viewed in FIG. 7) tension forces apply shear stress to superficial fascia and to deep fascia in the body of the patient. The tension forces may be transmitted to fascia associated with muscles of the patient, that is myofascia.
As the main portion 16 of the strap 10 is wrapped across the base end portion 12 of the strap, the main portion of the strap is pulled toward the right (as viewed in FIG. 7). This results in the application of a combination of shear and compressive forces to the skin 60 and superficial fascia immediately beneath the skin 60. The application of shear forces to fatty tissue beneath the skin 60 can result in rupturing of fat globules and subsequent dissipation of the fat.
During a second turn or winding of the main portion 16 of the strap 10 around the portion 62 of the patient's body in a second loop, the strap continues to be pulled toward the right (as viewed in FIG. 7) with an increased force. Increased tension forces in the second loop have shear components extending along the axis about which the strap 10 is wound, that is, about the longitudinal central axis of the portion 62 of the patient's body. This results in the application of sidewise shear forces to deep fascia in the patient's body, such as myofascia. The sidewise shear forces applied to the deep fascia in the patient's body are effective to pull the deep fascia toward the right (as viewed in FIG. 7). As each successive turn of the strap 10 is wrapped around the portion 62 of the patient's body to form another loop, the force with which the strap is tensioned may be increased.
Increasing the tension forces in the strap 10 as the strap is wound around the portion 62 of the patient's body increases both the compressive force applied against the portion 62 of the patient's body and the shear forces applied to tissue beneath the skin 60 of the patient's body by the loops in the strap. The tension forces resulting from pulling the strap 10 have axial components. These axial components cause a shifting of the skin 60 of the patient toward the right (as viewed in FIGS. 7 and 8) and a shifting of both superficial fascia and deep fascia toward the right.
As the strap 10 is wrapped around the portion 62 of the patient's body, tension force, indicated by an arrow in FIG. 7, is transmitted from a loop being formed in the strap to previously formed loops in the strap. Thus, each of the loops formed in the strap 10, after the first loop, is effective to transmit force to an adjacent loop in the strap. The transmission of force between the loops of the strap has a compounding effect to increase the force transmitted to superficial fascia and deep fascia in the portion 62 of the patient as the strap 10 is wrapped around the portion 62 of the patient.
The extent of shifting movement of the deep fascia and/or other body tissue can be controlled by controlling the tension applied to the strap 10. Thus, the greater the shear or axially directed force which is to be applied to the deep fascia, the greater is the tension which is applied to the strap 10 as the strap is wound around the portion 62 of the patient's body. There is a relatively high coefficient of friction between the inner side surface 32 of the layer 34 of foam (FIG. 3) and the skin 60 (FIGS. 7 and 8) on the portion 62 of the patient's body. Therefore, substantial forces directed in an axial direction along the portion 60 of the patient's body can be applied by the strap 10 during winding and tensioning of the strap.
When the strap 10 has been fully wrapped in a series of loops around the portion 62 of the patient's body, the retainer end portion 14 of the strap is connected with the main portion 16 of the strap. To effect this interconnection, the retainer 38 (FIG. 4) on the retainer end portion 14 of the strap is pressed firmly against the layer 28 of fabric on the main portion 16 of the strap. As this occurs, the hooks 42 (FIG. 4) on the retainer 38 engage the loops of the layer 28 of fabric against which the retainer end portion 14 of the strap is pressed (FIG. 8). This results in the retainer end portion 14 of the strap 10 being connected to the main portion 16 of the strap to hold the strap against movement relative to the portion 62 of the patient's body.
Although only three turns of the strap 10 have been illustrated in FIG. 8 as being looped around the portion 62 of the patient's body, a greater or lesser number of could be wound around the patient's body. Of course, if additional turns of the strap 10 are to be wound around the portion 60 of the patient's body, the length of the strap 10 would be increased. Similarly, if fewer turns were to be wound around the portion 62 of the patient's body, the length of the strap would be decreased.
The strap 10 may be wrapped around a patient's forearm, in the manner illustrated in FIGS. 6-8, when the strap is being used in the treatment of tennis elbow or a similar disorder. Of course, the strap 10 may be wrapped around a patient's leg, in the manner illustrated in FIGS. 6-8, when the strap is being used in the treatment of a disorder associated with the patient's leg. Although the strap 10 is illustrated in FIGS. 6-8 as being wrapped around only one portion 62 of the patient's body, the strap could be wrapped around a plurality of portions of a patient's body if desired. This could be done in many different ways including a technique similar to the technique used in forming a buddy bandage between two portions of a patient's body.
In FIG. 8, the strap 10 is wound in a series of overlapping loops. However, it is contemplated that space could be provided between at least some of the loops. For example, after the first loop has been formed in the manner illustrated in FIG. 7, a next succeeding loop could be formed by winding the strap 10 around a portion of the patient's body which is spaced from the portion engaged by the first loop.
It is contemplated that modalities could be held in position relative to a patient's body by the strap 10. For example, magnets could be secured to the layer 28 of fabric by “Velcro™” hook type fasteners or could be positioned between the layer 34 of foam and the patient's body. The strap 10 could be utilized to position electrical stimulus or monitors relative to the patient's body. If desired, the strap 10 could be used to position ice packs relative to the patient's body.
It is contemplated that the device for use in treatment of portions of a patient's body may be held in place by the use of one or more straps having the same construction as the strap 10. These devices may be utilized for many different purposes including the straightening or correction of a deformity or disability. A device positioned by a strap having the same construction as the strap 10, may be used for the fixation, union or protection of a portion of a patient's body. The device positioned by a strap 10 may be used to correct malalignment of joints, bones, or other portions of a patient's body. Although the strap 10 may be used to position many different devices relative to a patient's body, some devices which may be positioned by the strap 10 may have a construction similar to the construction of the devices illustrated in U.S. Pat. Nos. 433,227; 3,698,389; 4,441,489; 4,848,326; 5,685,830; and 5,848,979.
It is also contemplated that one or more straps, having the same construction as the strap 10, may be utilized to position a portion of a patient's body relative to a portion of a device spaced from a patient's body. For example, a strap having a construction similar to the construction of the strap 10 could be utilized to position a portion of a patient's body relative to an imaging apparatus, such as a magnetic resonance imaging unit (MRI). The strap 10 could be utilized in association with an apparatus similar to the apparatus disclosed in U.S. Pat. No. 5,577,503.
Use of Strap—FIGS. 9-11
In the embodiment of the invention illustrated in FIGS. 6-8, the strap 10 has been wound around a generally cylindrical portion of a patient's body, such as around a patient's forearm or the lower portion of a patient's leg. In the embodiment of the invention illustrated in FIGS. 9-11, the strap is wrapped around the patient's hand and the region of the patient's body where the patient's wrist and hand are interconnected. Since the embodiment of the invention illustrated in FIGS. 9 and 10 is generally similar to the embodiment of the invention illustrated in FIGS. 1-8, similar numerals will be utilized to identify similar components, the suffix letter “a” being added to the numerals of FIGS. 9 and 10 to avoid confusion.
When a strap 10 a is to be wound around a hand 70 of a patient, a base end portion 12 a (FIG. 9) of the strap 10 a is positioned in engagement with the back 74 of the hand. The main portion 16 a of the strap 10 a is positioned between the first finger 78 (FIG. 10), that is, the thumb, and the second finger 80, that is, the forefinger. As the strap 10 a is wrapped around the hand 70, the layer 34 a of foam on the main section 16 a of the strap engages the back 74 of the hand 70 and is positioned in engagement with the palm of the hand.
As the strap 10 a is tensioned, the layer 34 a of foam on the main portion 16 a of the main portion of the strap is positioned in engagement with an exposed layer 6 f foam on the base end portion 12 a of the strap. There is a relatively large coefficient of static friction between the layer 34 a of foam on the main portion 16 a of the strap and the exposed layer of foam on the outer side of the base end portion 12 a of the strap. There is also a large coefficient of static friction between the layer 34 a of foam on the inner side of the base end portion 12 a of the strap 10 a and the skin on the hand 70 of the patient. These large coefficients of static friction result in the base end portion 12 a of the strap being secured between the back 74 of the patient's hand 70 and the main portion 16 a of the strap 10 a.
As the strap 10 a is wrapped in a loop around the patient's hand, in the manner indicated schematically by an arrow in FIG. 10, the strap is tensioned to firmly press the base end portion 12 a of the strap 10 a against the back 74 of the patient's hand 70. The strap 10 a is pulled into engagement with the patient's wrist and is wrapped in a plurality of loops around a region 84 (FIG. 11) where the patient's hand, wrist, and forearm are interconnected. This force results in bones and/or other tissue in the patient's hand 70 being held in a desired relationship. In addition, shear forces are transmitted to myofascial tissue disposed adjacent to the strap 10 a.
A retainer end portion 14 a of the strap 10 a is pressed against the layer 28 a of fabric on the main portion 16 a of the strap 10 a. The retainer section 14 a has a hook-type retainer, corresponding to the retainer 38 of FIG. 4, which securely anchors the retainer end portion 14 a of the strap 10 a against movement relative to the main portion 16 a of the strap. By tensioning the strap 10 a as it is wrapped around the region 84 where the hand, wrist, and forearm are interconnected in the wrist is held in extension.
The connection between the retainer section 14 a and the loop in the strap 10 a results in tension forces, indicated by an arrow in FIG. 11, being maintained. These tension forces are transmitted to myofascial tissue and bones in the hand, wrist and forearm of the patient.
In the embodiment of the invention illustrated in FIGS. 9-11, the base end portion 12 a of the strap 10 a has been positioned in engagement with the back 74 of the patient's hand 70. However, it is contemplated that the base end portion 12 a of the strap could be located in a different position relative to the hand 70 if desired. For example, the base end portion 12 a could be positioned in engagement with the palm of the hand 70.
Use of Strap—FIGS. 12-14
In the embodiment of the invention illustrated in FIGS. 9-11, the strap 10 a is wrapped around the hand 70 and region 84 where the hand and wrist are interconnected. In the embodiment of the invention illustrated in FIGS. 12-14, the strap is wrapped around the first finger (thumb) and then wrapped around the region where the hand and wrist are interconnected. Since the embodiment of the invention illustrated in FIGS. 12-14 is generally similar to the embodiments of the invention illustrated in FIGS. 1-11, similar numerals will be utilized to designate similar components, the suffix letter “b” being added to the numerals of FIGS. 12-14 to avoid confusion.
A strap 10 b is positioned relative to a patient's hand 70 b (FIG. 12) with a base end portion 12 b of the strap 10 b disposed in a region 84 b where the hand and wrist of the patient are interconnected. The layer 34 b of foam on the inside of the base end portion 12 b and main portion 16 b of the strap 10 b engages the skin on the hand 70 b of the patient. Once the base end portion 12 b of the strap 10 b has been positioned against the back of the patient's hand, the strap 10 b is pulled into the area between the first finger (thumb) 78 b and second finger (fore finger) 80 b on the hand of the patient (FIG. 12).
The main portion 16 b of the strap 10 b is then wrapped in a plurality of loops around the first finger (thumb) 78 b (FIG. 13). As the first finger 78 b is wrapped, the main portion 16 b of the strap is tensioned and the layer 34 b of foam is pressed firmly against the fabric layer 28 b on the main portion of the strap 10 b. Tension forces, indicated schematically by an arrow in FIG. 13, are transmitted to bones in the first finger 78 b and to tissue connected with the first finger.
The strap 10 b is then pulled downward and across the base end portion 12 b. This results in the layer 34 b of foam on the main portion 16 b of the strap 10 b being pressed against the exposed foam layer on the base end portion 12 b of the strap (FIG. 14). There is a relatively large coefficient of static friction between the foam layer 34 b on the main portion 16 b of the strap 10 b and the foam on the outside of the base end portion 12 b of the strap 10 b. There is also a relatively large coefficient of static friction between the foam layer 34 b on the inside of the base end portion 12 b and the skin on the back of the patient's hand 70 b. This results in the base end portion 12 b being securely held against movement relative to the hand 70 b of the patient by engagement of the main portion 16 b of the strap with the base end portion.
The strap 10 b is then wrapped for a plurality of turns around the region 84 b where the wrist, hand, and forearm of the patient are interconnected. A retainer end portion (not shown) having the same structure as the retainer end portion 14 of FIGS. 2 and 4 is then pressed against the fabric layer 28 b on the main portion 16 b of the strap 10 b to anchor the retainer end portion. The retainer portion maintains tension force, indicated by an arrow in FIG. 14, in the strap 10 b.
Although the strap 10 b has been illustrated in FIGS. 12-14 as being wrapped around the first finger (thumb) 78 b on the hand 70 b, it is contemplated that the strap could be wrapped around a different finger if desired. Although the base end portion 12 b of the strap 10 b has been shown disposed adjacent to the back of the hand 70 b of the patient, the base end portion 12 b of the strap 10 b could be positioned adjacent to the palm of the hand 70 b if desired.
Use of Strap—FIGS. 15-17
In the embodiment of the invention illustrated in FIGS. 9-14, the strap is utilized in association with a hand of a patient. In the embodiment of the invention illustrated in FIGS. 15-17, the strap is utilized in association with a knee of the patient. Since the embodiment of the invention illustrated in FIGS. 15-17 is generally similar to the embodiments of the invention illustrated in FIGS. 1-14, similar numerals will be utilized to designate similar components, the suffix letter “c” being added to the numerals of FIGS. 15-17 to avoid confusion.
The patella or kneecap of a patient may tend to shift toward the outside of the knee of the patient. By applying force against the patella with a strap 10 c, the patella can be moved medially inward from a laterally displaced position. It should be understood that the strap 10 c could be utilized to move a patella back into alignment with a knee from a different position if desired. Thus, the strap 10 c may be utilized to displace the patella back into a desired position. This may be accomplished by using the strap to pull the patella and deeper tissue—myofascial structures.
When the strap 10 c is to be utilized to move a patella or kneecap on a right leg 88 of a patient from a laterally displaced position, a base end portion 12 c of the strap 10 c is positioned laterally or outward of the center of the right patella or kneecap (FIG. 15). The main portion 16 c is pulled medially or inward across the top of the patella or kneecap in the manner illustrated schematically in FIG. 15.
As the strap 10 b is wrapped around the right leg 88 of the patient, the layer 34 c of foam on the main portion 16 c of the strap 10 c is positioned in engagement with skin 60 c on a right leg of the patient. The main portion 16 c of the strap 10 c extends upward across the anterior side of the patient's leg 88 at a location immediately above the patella. When the strap reaches the center of the medial side of the leg, at a location above the patella, the strap is pulled laterally downward across the posterior side of the leg (FIGS. 15 and 16).
As the main portion 16 c of the strap 10 c is pulled downward across the outside of the knee in the manner illustrated in FIG. 16, the foam layer 34 c on the strap engages the base end portion 12 c of the strap to press the base end portion firmly against the skin 60 c of the patient. The relatively large coefficient of static friction between the foam on the outside of the base end portion 12 c of the strap 10 c and the foam on the inside of the main portion 16 c of the strap results in a secure connection between the base end portion and main portion of the strap. The relatively large coefficient of static friction between the foam on the inside of the base end portion 12 c of the strap 10 c and the skin on the leg of the patient results in a secure connection between the base end portion of the strap and the leg of the patient.
The resulting loop encircles the leg 88 of the patient immediately above the kneecap. As the strap 10 c is pulled downward and leftward, as viewed in FIG. 16, force is applied to both the upper and lower portions of the kneecap (patella) by the strap. The resulting force component pushes the right kneecap inward toward the left kneecap.
The patella or kneecap is centered in a triangular space 92 formed by an intersection 94 (FIG. 16) between the main portion 16 c of the strap 10 c extending medially upward across an upper portion of the patella and a section of the main portion 16 c of the strap 10 c which extends medially downward and across a lower portion of the patella. These tension forces, indicated by an arrow in FIG. 16, are transmitted to body tissue disposed beneath the strap 10 c. As the main portion 16 c of the strap 10 c is pulled downward and medially inward across the lower portion of the patella (FIG. 16), the main portion 16 c of the strap is tensioned downward and forward relative to the knee of the patient. This results in the sections of the main portion 16 c of the strap 10 c, which form the triangular space 92, pressing against the patella to urge the patella medially inward from a laterally displaced position.
The manner in which force is applied against the patella by the strap 10 c is illustrated schematically in FIG. 17 in association with a knee of a patient. The patella or knee cap is illustrated schematically in FIG. 17 and is designated by the numeral 95. It should be understood that FIG. 17 is a schematic frontal view of the patient's knee and the patella 95 has been illustrated in solid lines even though the patella is covered by skin and other body tissue.
The upper loop of the strap 10 c has been designated by the numeral 96 in FIG. 17. The upper loop 96 of the strap 10 c applies a downward force component 97 and a right ward (as viewed in FIG. 17) force component 98 to the patella 95. Similarly, the lower loop of the strap 10 c has been designated by the numeral 99 in FIG. 17. The lower loop 99 of the strap 10 c applies an upward force component 100 and a rightward (as viewed in FIG. 17) force component 101 to the patella 95.
The downward and upward force components 97 and 100 are substantially equal and cancel each other. The rightward force components 98 and 101 applied against the patella 95 result in a relatively large force 103 which moves the patella 95 toward the right (as viewed in FIG. 17). This results in body tissues around the patella 95 being tensioned under the influence of the force components 98 and 101 transmitted from the strap 10 c.
The patella 95 is moved into alignment with the other bones in the leg 88 of the patient by the force applied against the patella by the strap 10 c. The main portion 16 c of the strap 10 c is then pulled to the center of the inner side of the leg of the patient. The main portion 16 c of the strap is then pulled upward and across the anterior portion of the leg 88 of the patient to form a pair of loops, that is, the upper loop 96 which extends around the leg and is disposed above the patella 95 and a lower loop which extends around the leg and is disposed below the patella. Force transmitted from the intersection 94 between the two loops formed by the main portion 16 c of the strap 10 c forces the patella toward the left on the leg of the patient and into alignment with the knee of the patient.
The retainer end portion 14 c of the strap 16 c is then connected with the main portion 16 c of the strap at a location below the patella (FIG. 18). Rather than being connected with the downwardly extending section of the main portion 16 c of the strap 10 c, as shown in FIG. 18, the retainer end portion 14 c could be connected with the section of the main portion 16 c of the strap 10 c which extends upward across the upper side of the patella.
Use of Strap—FIG. 19
In the embodiment of the invention illustrated in FIGS. 9-14 the strap is utilized in association with a patient's hand. In the embodiment of the invention illustrated in FIGS. 15-18 the strap is utilized in association with a patient's knee. In the embodiment of the invention illustrated in FIG. 19, the strap is utilized in association with the arms and shoulders of a patient. Since the embodiment of the invention illustrated in FIG. 19 is generally similar to the embodiment of the invention illustrated in FIGS. 1-18, similar numerals will be utilized to identify similar components, the suffix letter “d” being added to the numerals of FIG. 18 to avoid confusion.
A strap 10 d has base end portion 12 d, a main portion 16 d and a retainer end portion 14 d. The strap 10 d is wrapped around the upper portion of right and left arms 102 and 104 and the trunk 106 of a patient. The strap 10 d applies force against the upper portion of the arms 102 and 104. The strap 10 d applies pressure against muscles and other body tissue connected with the shoulders of the patient. The strap 10 d is effective to retard and increase proprioception of upward rotational movement of the arms 102 and 104.
When the strap 10 d is to be positioned relative to the patient, the base end portion 12 d of the strap is positioned against the upper portion of the left arm 104 (FIG. 19). The main portion 16 d of the strap 10 d is then tensioned across the back of the patient. The layer of foam on the main portion 16 d of the strap, that is, the layer corresponding to the layer 34 of foam in FIG. 3, engages the skin on the back of the patient. The layer of fabric, that is the fabric layer corresponding to the layer 28 of FIG. 3, faces away from the skin of the patient.
While the base end portion 12 d is held against movement, the main portion 16 d of the strap 10 d is tensioned and the strap positioned across the chest of the patient. The layer of foam on the main portion 16 d of the strap is then moved into engagement with the upper layer of the base end portion 12 d. The layer of foam on the section 16 d of the strap engages the exposed foam on the base end portion 12 d of the strap and is effective to anchor the base end portion 12 d of the strap against movement. The retainer end portion 14 d of the strap is then connected with the fabric layer on the main portion 16 d of the strap.
Engagement of the layer of foam on the main portion 16 d of the strap 10 d with skin on the back and chest of the patient increases patient awareness of use of muscles and related tissue connected with the upper portions of the arms 102 and 104 of the patient. The increased patient proprioception facilitates treatment of upper arm and shoulder disorders. In addition, the strap 10 d makes it easier for a patient to voluntarily limit the range of upper arm movement.
Use of Strap—FIG. 20
In the embodiment of the invention illustrated in FIGS. 1-19, the base end portion 12 of the strap 10 is positioned in engagement with skin on a portion of a patient's body and a layer of foam on the inside of the strap is positioned in engagement with foam on the outside of the base end portion. In the embodiment of the invention illustrated in FIG. 20, the base end portion of the strap is a preformed loop with foam on the inside. Since the embodiment of the invention illustrated in FIG. 20 is generally similar to the embodiments of the invention illustrated in FIGS. 1-19, similar numerals will be utilized to identify similar components, the suffix letter “e” being added to the numerals of FIG. 19 to avoid confusion.
A strap 10 e is utilized in association with a hand 70 e of a patient. The strap 10 e has a base end portion 12 e, a main portion 16 e, and a retainer end portion (not shown) corresponding to the retainer end portion 14 of FIGS. 2 and 4. The main portion 16 e of the strap 10 e includes a layer 28 e of fabric and a layer 34 e of foam. The main portion 16 e of the strap 10 e has the same construction as the main portion 16 of the strap 10 of FIGS. 1-5. As was previously mentioned, the retainer end portion of the strap 10 e has the same construction as the retainer end portion 14 of the strap 10 of FIGS. 1-5.
The strap 10 e differs from the strap 10 of FIGS. 1-5 in that the base end portion 12 e is a preformed loop 114 which is positioned around the first finger (thumb) 78 e on the hand 70 e of the patient. The inside of the loop 114 is completely lined by the layer 34 e of foam. The outside of the loop 114 is formed by the layer 28 e of fabric.
The loop 114 is formed by folding the end of the strap back on itself and heart staking the end of the strap to the main portion of the strap when a loop 114 of a desired diameter has been formed. This results in the inside of the loop being completely lined by the foam layer 34 e. The outside of the loop is formed by the fabric layer 28 e. The loop 114 is connected to the main portion 16 e of the strap 10 e where the loop is heat staked to the strap.
The size of the loop 114 will vary depending upon the finger on the hand 70 of the patient with which the loop is to be associated. Thus, if the loop is to be associated with the fifth finger (little finger) the loop would have a relatively small diameter. Similarly, if the strap 10 e is to be utilized with a person having a relatively small hand, the loop 114 would be relatively small. However, if the loop 114 is to be associated with a relatively large muscular hand, the loop would be relatively large. It should be understood that it is contemplated that the strap 10 e will be associated with any one of the fingers on hands of different sizes.
Once the loop 114 formed by the base end portion 12 e of the strap 10 e has been positioned around the first finger 78 e on the hand 70 e, the strap is wrapped around the first finger. As the main portion 16 e of the strap 10 e is wrapped around the first finger 78 e, the foam layer 34 e is pressed against the fabric layer 28 e on the outside of the loop 114. The main portion 16 e of the strap 10 e is then wrapped around the region where the patient's hand and wrist are interconnected.
When the strap 10 e is used, the loop 114 is placed around the first finger 78 e. The main portion 16 e of the strap 10 e is tensioned and the strap is wrapped in a clockwise direction (as viewed in FIG. 20) around the first finger 78 e. As this occurs, the layer 34 e of foam on the main portion 16 e of the strap 10 e is pressed against the layer 28 e of fabric on the outside of the loop 114.
After the strap 10 e has been wrapped for more than one complete revolution about the first finger 78 e, the strap is moved along the back of the thumb and across a portion of the back of the hand where the thumb is joined with the hand, to a region where the wrist and hand of the patient are interconnected. The strap is then wrapped for a plurality of turns in a clockwise direction about the wrist of the patient. The retainer end portion of the strap then engages the fabric layer 28 e to secure the strap in the manner previously explained in conjunction with the embodiment of the strap illustrated in FIGS. 1-5.
In the embodiment of the invention illustrated in FIG. 20, the strap 10 e is provided with a preformed loop 114 for engagement with a finger 78 e on a hand 70 e of a patient. However, it is contemplated that the loop could be preformed for engagement with another portion of a patient's body. For example, the size of the loop 114 could be increased so that the loop could be utilized to engage an upper portion of an arm of a patient. Alternatively, the loop could be sized so as to engage a portion of a leg of a patient. If desired, the loop 114 could be sized so as to engage a toe on a foot of a patient. Although only a single loop 114 has been illustrated in FIG. 20, a plurality of loops could be formed in the strap 10 e if desired.
Use of Strap—FIG. 21
In the embodiment of the invention illustrated in FIGS. 1-5, the strap 10 is provided with a base end portion 12 and a retainer end portion 14. In the embodiment of the invention illustrated in FIG. 21, a plurality of straps which have the same construction throughout their length are utilized to apply force against shoulders of a patient. Since the embodiment of the invention illustrated in FIG. 20 is generally similar to the embodiments of the invention illustrated in FIGS. 1-20, similar numerals will be utilized to designate similar components, the suffix letter “f” being added to the numerals of FIG. 21 to avoid confusion.
The straps 10 f and 120 are utilized to apply force against shoulders 122 and 124 of a patient. The straps 10 f and 120 extend across the shoulders 122 and 124 of the patient and down posterior and anterior sides of a trunk 128 of the patient. Although the portions of the straps 10 f and 120 disposed on the anterior side of the patient's trunk are illustrated in FIG. 21, it should be understood that the straps extend straight down the posterior side of the trunk 128 of the patient. Therefore, the portion of the straps which extend down the posterior side of the patient's trunk 128 extend generally parallel to and are aligned with the portions of the straps which extend down the anterior side of the patient's trunk. The straps 10 f and/or 120 may be utilized in the treatment of a fractured clavicle or other bone in the shoulder of the patient.
The strap 10 f has a uniform construction throughout its length. The strap 10 f has the same construction as the main portion 16 of the strap 10 of FIGS. 1-3. Thus, the strap 10 f includes an outer fabric layer 28 f and an inner foam layer, corresponding to the foam layer 34 of FIG. 3. The inner foam layer of the strap 10 f is disposed in engagement with skin on the trunk 128 of the patient.
Due to a gripping action between the foam layer on the inside of the strap 10 f and the skin 60 f on the trunk 128 of the patient, a tension force can be maintained in the strap 28 f. This tension force is effective to apply pressure against scapula muscles to relieve myofascial pain or other maladies. In addition, the strap is effective to increase the patient's proprioception of the shoulder 122. Increased awareness of the shoulder 122 results from pulling of the strap 10 f on the skin 60 f of the trunk 128 of the patient during movement of the arm connected with the shoulder. Opposite ends of the strap 10 f extend to the patient's waist. This enables opposite ends of the strap 10 f to be held in position on the patient's trunk 128 by clothing, such as a belt, worn by the patient.
The strap 10 f may be utilized by itself or in association with a second strap 120. The strap 120 has the same construction as the strap 10 f and is positioned in the same manner relative to the opposite shoulder 124. The strap 120 cooperates with the patient's shoulder 124 and trunk 128 in the same manner as previously discussed in association with the strap 10 f. It should be understood that either one of the two straps 10 f or 120 may be utilized by itself without the other strap if desired.
Use of Strap—FIGS. 22 and 23
In the embodiment of the invention illustrated in FIG. 21, the two straps 10 f and 120 are held in position relative to the trunk 128 of the patient by a gripping action between the layers of foam on the inside of the straps and the skin 60 f of the patient along with clothing worn by the patient. In the embodiment of the invention illustrated in FIGS. 22 and 23, the straps over the shoulders of the patient are held in position relative to the trunk of the patient by a third strap which extends around the trunk of the patient. Since the embodiment of the invention illustrated in FIGS. 22 and 23 is generally similar to the embodiments of the invention illustrated in FIGS. 1-21, similar numerals will be utilized to designate similar components, the suffix letter “g” being added to the numerals of FIGS. 22 and 23 to avoid confusion.
Straps 10 g and 120 g extend across opposite shoulders 122 g and 124 g of a patient. The straps extend down posterior and anterior sides of a trunk 128 g of the patient. The straps 10 g and 120 g apply force to scapula muscles and/or other tissue in the shoulders 122 g and 124 g of the patient. The straps 10 g and/or 120 g may be utilized in the treatment of a fractured clavicle or other bone in a shoulder of the patient.
The strap 10 g is provided with base end portions at opposite ends of the strap. Thus, the strap 10 g has a base end portion 12 g at the end of the strap 10 g disposed on the anterior side of the trunk 128 g of the patient. Similarly, the strap 10 g has a base end portion at the end of the strap on the posterior side of the trunk of the patient.
The base end portions at opposite ends of the strap 10 g have the same construction as the base end portion 12 of FIGS. 1, 2 and 5. Thus, an anterior base end portion 12 g of the strap 10 g has a layer of foam, corresponding to the lower layer 50 of FIG. 5, which engages the skin 60 g on the trunk of the patient. The end portion 12 g of the strap 10 g has an outer layer, corresponding to the upper layer 48 of FIG. 5, which faces outward away from the skin 60 g on the anterior side of trunk 128 g of the patient.
Although only the anterior side base end portion 12 g of the strap 10 g is illustrated in FIG. 22, it should be understood that there is a similar base end portion at the end of the strap 12 g disposed on the posterior side of the trunk 10 g of the patient. The two base end portions both have the same construction as the base end portion 12 of the strap 10 illustrated in FIGS. 1-5. The strap 10 g does not have an end portion with a construction which corresponds to the construction of the retainer end portion 14 of the strap 10 of FIGS. 1-5.
The portion of the strap 10 g extending between the opposite base end portions, that is, between the anterior base end portion 12 g and the corresponding posterior base end portion, has the same construction as the main portion 16 of the strap 10 of the embodiment of the invention illustrated in FIGS. 1-5. Thus, the strap 10 g has a layer of fabric 28 g which extends for the entire length of the strap 10 g. A layer of foam, corresponding to the layer 34 of foam of FIG. 3, is disposed on the side of the strap 10 g toward the skin 60 g of the patient. The layer of foam extends throughout the entire length of the strap 10 g. The layer of foam on the inside of the strap 10 g is effective to grip the skin 60 g of the patient to hold the strap against movement relative to the skin.
The strap 120 g has the same construction as the strap 10 g. Thus, the strap 120 g has a pair of base end portions with-the same construction as the base end portion 12 of the strap 10 of FIGS. 1-5. There is a base end portion, with the same construction as the base end portion 12 of FIG. 5, at the end of the strap 120 g disposed on the anterior side of the trunk 128 g of the patient. Similarly, there is a base end portion with the same construction as the base end portion 12 of FIG. 5 at the end of the strap 120 g disposed on the posterior side of the trunk of the patient. The posterior and anterior base end portions of the straps 10 g and 120 g are aligned with each other in a transverse plane extending through the trunk of the patient.
In accordance with a feature of the embodiment of the invention illustrated in FIG. 22, a retaining strap 136 extends around the trunk 128 of the patient. The retaining strap 136 holds the two straps 10 g and 120 g in desired positions relative to the trunk 128 g and shoulders 122 g and 124 g of the patient. The retaining strap 136 has the same construction as the strap 10 of FIGS. 1-5.
The retaining strap 136 has a base end portion with foam on opposite sides of the base end portion, in the same manner as illustrated in FIG. 5. The retaining strap 136 has a retainer end portion with a retainer having the same construction as the retainer 38 of FIG. 4. The retainer end portion of the strap 136 has the same construction as the retainer end portion 14 of the strap 10 of FIG. 4. A main portion extends between the base end portion and retainer end portion of the retaining strap 136 of FIG. 22. The main portion of the retaining strap 136 has the same construction as the main portion 16 of the strap 10 of FIGS. 1-5.
When the straps 10 g, 120 g and 136 are to be utilized to treat a patient, the straps 10 g and 120 g are first positioned across the shoulders 122 g and 124 g and down the posterior and anterior sides of the trunk 128 g. The retaining strap 136 is then positioned around the trunk 128 g. The layer of foam on the main portion 16 of the retaining strap 136 engages the posterior and anterior base end portions of the strap 10 g and the posterior and anterior base end portions of the strap 120 g. Engagement of the layer of foam on the inside of the retaining strap 136 with the foam on the outside of the base end portions of the straps 10 g and 120 g holds the base end portions of the straps against movement relative to the trunk 128 g of the patient.
When the retaining strap 136 is to be positioned around the trunk 128 g of the patient, the base end portion of the retaining strap 136 is positioned on either the left or right side of the trunk adjacent to either the left or right arm of the patient. The main portion of the retaining strap 136 is then wrapped around the trunk of the patient. As this is done, the layer of foam, corresponding to the layer 34 of foam on the main portion 16 of the strap 10 (FIGS. 1-3), is positioned in engagement with the anterior and posterior base end portions 12 g (FIG. 22) of the strap 10 g. The layer of foam on the main portion of the retaining strap 136 is also positioned in engagement with the base end portions of the strap 120 g disposed on the anterior and posterior sides of the trunk 128 g of the patient.
The layer of foam on the inside of the main portion of the retaining strap 136 is then positioned in engagement with the layer of foam on the outside of the base end portion of the retaining strap 136. The retainer end portion of the retaining strap 136 is connected with the layer of fabric on the outside of the main portion of the retaining strap in the same manner as previously explained in conjunction with the embodiment of the invention illustrated in FIGS. 1-5.
In the embodiment of the invention illustrated in FIG. 22, the retaining strap 136 is positioned around the waist of the patient. However, it is contemplated that the retaining strap 136 could be positioned at a different location relative to the trunk 128 g of the patient. For example, the retaining strap 136 could be positioned around the chest of the patient. If desired, a plurality of retaining straps, having the same construction as the retaining strap 136, could be positioned at a plurality of locations around the trunk 128 g of the patient. Connector straps could be connected with and extend between the straps 10 g and 120 g on the posterior and/or anterior sides of the trunk of the patient. The relatively short connector straps could be used with or without the retaining strap 136.
The manner in which the retaining strap 136 cooperates with the strap 120 g extending across the shoulder 124 g (FIG. 22) of the patient is illustrated in FIG. 23. The shoulder strap 120 g includes a main portion 16 g having a layer 34 g of foam and a layer 28 g of fabric. The layer 34 g of foam has an inner side surface 32 g which engages the skin 60 g of the patient.
The shoulder strap 120 g has an anterior base end portion 12 g (FIG. 23). The base end portion 12 g of the strap 120 g includes a lower or inner layer 50 g and an upper or outer layer 48 g. The layers 48 g and 50 g of the end portion 12 g of the shoulder strap 120 g are integrally formed as one piece with the main portion 16 g of the shoulder strap. The layers 48 g and 50 g on the base end portion 12 g of the shoulder strap 120 g are fixedly connected to each other by heat staking. Of course, the layers 48 g and 50 g could be fixedly interconnected in a different manner if desired.
The retaining strap 136 has a main portion 16 g which extends across the base end portion 12 g of the shoulder strap 120 g. The main portion 16 g of the retaining strap 136 includes a layer 28 g of fabric and a layer 34 g of foam. The layer 34 g of foam on the main portion 16 g of the retaining strap 136 is disposed in engagement with the layer of foam on the upper or outer layer 48 g of the base end portion 12 g of the shoulder strap 120 g. The gripping action between the layers of foam on the base end portion 12 g of the shoulder strap 120 g and the main portion 16 g of the retaining strap 136 is effective to interconnect the two straps and hold them against movement relative to each other.
In the embodiment of the invention illustrated in FIGS. 22 and 23, the base end portion 12 g of the shoulder strap 120 g (FIG. 22) includes an upper or outer layer 48 g and a lower or inner layer 50 g having layers of fabric and foam which are integrally formed as one piece with the layer 28 g of fabric and the layer 32 g of foam of the main portion 16 g of the strap 120 g. However, a layer of foam could be bonded directly on the outer or upper side of the layer of fabric 28 g which extends through the lower layer 50 g of the base end portion 12 g of the shoulder strap 120 g. This would result in the base end portion 12 g of the shoulder strap having only a single layer of fabric rather than the two layers formed by doubling over the layer 28 g of fabric.
In the embodiment of the strap 120 g illustrated in FIGS. 22 and 23, the shoulder strap 120 g ends at the retaining strap 136. However, if desired, the shoulder strap 120 g could extend downward past the retaining strap 136. If this was done, the shoulder strap 120 g would extend to the left (as viewed in FIG. 23) of the retaining strap 136. With such a construction, it is believed that it may be preferred to bonded a layer of foam directly on the layer 28 g of fabric of the shoulder strap 120 g for engagement by the retaining strap 136. Alternatively, a separate piece or segment of the strap material could be connected to the main portion 16 g of the shoulder strap 120 g by heat staking. This would result in a construction similar to that illustrated in FIG. 23 with the exception of elimination of the bend 52 g between the upper or outer layer 48 g and the lower or inner layer 50 g and in continuation of the main portion 16 g of the strap 120 g to the left (as viewed in FIG. 23) of the retaining strap 136.
Although two shoulder straps 10 g and 120 g have been illustrated in FIG. 22, a single shoulder strap could be utilized if desired. It should be understood that a plurality of retaining straps 136 could be used with one or more shoulder straps if desired. When two shoulder straps 10 g and 120 g are utilized, short connector straps may be extended between the shoulder straps. Although it is believed that the retaining strap 136 will be used with the connector straps, the connector straps may be used without the retaining straps.
Use of Strap Material—FIGS. 24 and 25
In the embodiments of the invention illustrated in FIGS. 1-23, the layers of foam and fabric have been used as strap material. In the embodiment of the invention illustrated in FIGS. 24 and 25, the layers of foam and fabric are utilized as a lining for an orthosis. Since components of the embodiment of the invention illustrated in FIGS. 24 and 25 are similar to components of the invention illustrated in FIGS. 1-23, similar numerals will be utilized to designate similar components, the suffix letter “h” being associated with FIGS. 24 and 25.
An orthosis 142 is illustrated in FIG. 24. The orthosis 142 is illustrated schematically in association with an arm of a patient to move an elbow joint disposed between the upper arm and forearm of the patient. However, it should be understood that the orthosis 142 could be utilized in association with other portions of a body of a patient. It is contemplated that the orthosis 142 will be utilized to effect a static progressive stretching of viscoelastic tissue associated with a joint in a body of a patient.
The orthosis 142 includes a cuff 144 which is attachable with an upper portion of an arm of a patient and a cuff 146 which is attachable with a lower portion of an arm of a patient. The cuff 144 is slidable along a cuff arm 148. Similarly, the cuff 146 is slidable along a cuff arm 150.
A tower 154 is connected with the cuff arms 148 and 150. A drive mechanism 156 is connected with the tower 154 and the cuff arms 148 and 150. The drive mechanism 156 is manually operated. However, a motor could be utilized to operate the drive mechanism 156 if desired.
During use of the orthosis 142, the drive mechanism 156 is operated to cause the cuff arms 148 and 150 to pivot about connections with the tower 154. As the cuff arms are pivoted relative to the tower 154, the cuffs 144 and 146 move along the cuff arms.
The construction and manner of use of the orthosis 142 is the same as is disclosed in U.S. Pat. No. 5,453,075. The disclosure in the aforementioned U.S. Pat. No. 5,453,075 is hereby incorporated herein in its entirety by this reference thereto. The orthosis could have a different construction than the specific construction of the orthosis 142. For example, the orthosis could have a construction similar to that disclosed in U.S. Pat. No. 5,685,830 or 5,848,979.
In accordance with a feature of the invention, the cuffs 144 and 146 of the orthosis are lined with the same material which forms the main portion 16 of the strap 10. Thus, the cuff 146 has a lining 160. The lining 160 includes a layer 28 h of fabric which is fixedly secured, for example, by adhesive and/or heat staking, to the cuff 146. A layer 34 h of foam is provided on the inside of the lining 160. The layer 34 h of foam engages the skin on the patient's body. It should be understood that the layer 28 h of fabric and the layer 34 h of foam has the same construction as the layer 28 of fabric and the layer 34 of foam of FIGS. 1-5.
Use of Straps—FIGS. 26 and 27
In the embodiment of the invention illustrated in FIGS. 25 and 26, a plurality of straps are utilized to close an opening in a patient's skin. Since the straps of the embodiment of the invention illustrated in FIGS. 26 and 27 have the same general construction as the straps of the embodiment of the invention illustrated in FIGS. 1-23, similar numerals will be utilized to designate similar components, the suffix letter “j” being associated with the numerals of FIGS. 26 and 27 to avoid confusion.
An opening 170 (FIG. 26) is formed in the body of a patient. The opening extends through an outer surface 172 of the skin 60 j of the patient into body tissue 174 disposed beneath the skin. The opening 170 may be formed by an incision, wound, or other cause.
In order to promote healing of body tissue, it is desirable to close the opening and press the body tissue 174 on opposite sides of the opening firmly together. This is accomplished by utilizing a pair of straps 180 and 182 (FIG. 27). The straps 180 and 182 are wrapped around a portion of the patient's body in which the opening 170 is disposed. The straps 180 and 182 are disposed on opposite sides of the opening 170.
The straps 180 and 182 apply tension forces to the body tissue 174 urging the body tissue on one side of the opening toward the body tissue on the other side of the opening. These tension forces are effective to close the opening 170 in the manner illustrated schematically in FIG. 27. An optional connector member 186 extends between the straps 180 and 182 and cooperates with the straps to hold the opening 170 closed. If desired, the connector member 186 could be eliminated and the opening 170 held in the closed condition of FIG. 27 by only shear or tension forces applied to the body tissue 174 by the straps 180 and 182.
The straps 180 and 182 have the same construction as the strap 10 of FIGS. 1-5. Thus, the strap 180 has a base end portion corresponding to the base end portion 12 of the strap 10, a main portion corresponding to the main portion 16 of the strap 10, and a retainer end portion corresponding to the retainer end portion 14 of the strap 10. Similarly, the strap 182 has a base end portion corresponding to the base end portion end portion 12 of the strap 10, a main portion corresponding to the main portion 16 of the strap 10 and a retainer end portion corresponding to the retainer end portion 14 of the strap 10. The two straps 180 and 182 both have the same construction as the strap 10 and are positioned around a portion of a patient's body in the same manner as previously described in conjunction with the strap 10.
A layer 34 j of foam on a main portion 16 j of the strap 180 is disposed in engagement with the skin 60 j on one side, that is the left side as viewed in FIG. 27 of the opening 120. A second turn of the main portion 16 j of the strap overlies a portion of the first turn of the strap. The layer of foam in the main portion of the second turn of the strap 34 j engages a layer 28 j of fabric in the first turn of the strap. The second loop of the strap 180 is tensioned and pulled toward the right (as viewed in FIG. 27) to apply force to the skin 60 j.
The force applied to the skin 60 j has a radially inward or compressive component and a tension component which extends parallel to the surface of the skin 60 j. The tension component of the force applied to the skin 60 j by the second turn of the strap 180 pulls the skin and underlying body tissue 174 toward the right (as viewed in FIG. 27). This rightward movement of the body tissue 174 results in a partial closing of the opening 170.
The strap 182 has the same construction as the strap 180. However, the second turn or winding of the strap 182 applies a leftward (as viewed in FIG. 27) force component to the skin 60 j and body tissue 174. This leftward force component moves the skin 60 j and body tissue on the right side of the opening 174 toward the skin and body tissue on the opposite or left side of the opening. This results in the opening being closed in the manner illustrated schematically in FIG. 27.
When the opening 170 is closed by oppositely directed shear or tension forces applied to the body tissue 174 by the straps 180 and 182, the body tissue on opposite sides of the opening is pressed together. Pressing the body tissue 174 on opposite sides of the opening 170 together promotes healing of the body tissue and permanent closing of the opening 170.
Although the straps 180 and 182 have been wrapped around the patient's body for only two complete turns, it is contemplated that the straps could be wrapped around the body tissue for additional turns if desired. If this was done, the tension or shear forces applied to the body tissue 174 tending to close the opening 170 would be increased. Of course, the wrapping of the straps 180 and 182 around the portion of the patient's body in which the opening 170 is formed would begin at a location spaced further from the opening to accommodate the additional turns of the straps.
An optional connector member 186 is illustrated in FIG. 27 as extending between the straps 180 and 182. The connector member 186 has the same construction as the retainer 38 of FIG. 4. Thus, the connector member 186 has a plurality of hooks which are engagable with the loop fabric layers 34 j on the outside of the straps 180 and 182.
The connector member 186 can be utilized to apply forces to the straps 180 and 182 urging them toward each other in order to further promote closing of the opening 170. Alternatively, the connector member 186 may merely be pressed in place against the straps 180 and 182 after the opening 170 has been closed by the shear forces applied to the body tissue 174 by the straps 180 and 182. This would result in the connector member 186 being effective to prevent separation of the straps 180 and 182 and subsequent reformation of the opening 170 after the opening has been closed.
When the opening 170 is disposed on a portion of a patient's body which is subjected to forces tending to re-establish the opening 170 during normal daily activities of the patient, it is believed that the connector member 186 will be particularly advantageous. Of course, in certain situations at least, the connector member 186 may be eliminated.
Use of Strap—FIGS. 28 and 29
In the embodiment of the invention illustrated in FIGS. 28 and 29, the strap is utilized to restrain movement of an arm of the patient. Since the embodiment of the invention illustrated in FIGS. 28 and 29 is generally similar to the embodiments of the invention illustrated in FIGS. 1-23, similar numerals will be utilized to designate similar components, the suffix letter “k” being added to the numerals of FIGS. 28 and 29 to avoid confusion.
A strap 10 k is wrapped around an arm 102 k and extends horizontally across posterior side of a trunk 128 k of a patient in the manner illustrated schematically in FIG. 29. The strap 10 k extends beneath the axilla between an arm 104 k and the trunk 128 k of the patient. The strap extends upward across the anterior side of the trunk 128 k of the patient adjacent to the arm 104 k. The strap 10 k extends across the shoulder 124 k of the patient (FIGS. 28 and 29). The strap 10 k extends downward across the posterior side of the shoulder 124 k and trunk 128 k of the patient (FIG. 29) to a connection 200 with a portion of the strap 10 k extending across the posterior side of the trunk 128 k of the patient.
Tension in the strap 10 k urges the arm 102 k of the patient toward the trunk 128 k of the patient and in a posterior direction. The strap 10 k tends to limit abduction of the right arm 102 k of the patient. Of course, if the strap 10 k was wrapped around the upper portion of the left arm 104 k of the patient and extended across the right shoulder 122 k of the patient, abduction of the left arm 104 k would be limited. The strap 10 k may be utilized in the treatment of a fractured clavicle or other bone in the shoulder of the patient.
When the strap 10 k is connected with the right arm 102 k and extends across the left shoulder 124 k of the patient, in the manner illustrated in FIGS. 28 and 29, proprioception of the patient to movement of the right arm 102 k is increased. This is because the layer of foam on the portion of the strap 10 k extending across the posterior side of the trunk 128 k and extending downward across the posterior side of the left shoulder 124 k of the patient transmits force to the skin 60 k on the posterior side of the trunk 128 k of the patient. This force increases the patient's awareness of how the right arm 102 k is being moved.
The strap 10 k has the same construction as the strap 10 of FIGS. 1-5. Thus, the strap 10 k (FIGS. 28 and 29) has a base end portion, corresponding to the base end portion 12 of the strap 10, a main portion 16 k corresponding to the main portion of the strap 10 and a retainer end portion 14 k corresponding to the retainer end portion 14 of the strap 10. The retainer end portion 14 k of the strap 10 k is connected with the main portion 16 k of the strap 10 k at the intersection 200 (FIG. 29) between the portion of the strap 10 k which extends across the posterior side of the trunk of the patient in a transverse plane and the portion of the strap 10 k which extends downward from the shoulder 124 k across the posterior side of the trunk 128 k.
When the strap 10 k is to be connected with the patient in the manner illustrated in FIGS. 28 and 29, the base end portion of the strap 10 k, corresponding to the base end portion 12 of the strap 10, is positioned in engagement with the front side of the upper arm of the patient at a location indicated by the numeral 204 in FIG. 28. The layer of foam on the inside of the main portion 16 k is positioned in engagement with the skin on the upper portion of the right arm of the patient. The strap 10 k is then wrapped across the portion of the upper arm of the patient which is furthest from the trunk of the patient. The strap 10 k is then is wrapped across the portion of the upper arm at the axilla between the right arm 102 k and the trunk 128 k of the patient.
The main portion 16 k of the strap 10 k is then pulled across the base end portion of the strap 10 k at the location designated by the numeral 204 in FIG. 28. This results in the foam layer on the inside of the strap, that is the foam layer corresponding to the foam layer 34 of FIGS. 1-5, engaging foam on the base end portion of the strap. The strap 10 k is then wrapped, for a second time, across the upper portion of the right arm 102 k which is furthest from the trunk 128 k of the patient. This results in the formation of a loop around the upper portion of the right arm 102 k of the patient.
The strap is then pulled across the posterior side of the patient's trunk. The tension in the main portion 16 k of the strap 10 k firmly presses the base end portion of the strap 10 k against the skin of the patient. The tension force and engagement of the layer of foam on the main portion 16 k of the strap 10 k with the layer of foam on the outside of the base end portion of the strap 10 k holds the main portion 16 k of the strap against movement relative to the loop which extends around the upper portion of the right arm 102 k of the patient.
The tension in the main portion 16 k of the strap results in the layer of foam on the inside of the main portion of the strap 16 k being pressed firmly against the posterior side of the trunk 128 k of the patient. The strap 16 k is then moved through the axilla formed between the upper portion of the left arm 104 k and trunk 128 k of the patient. The strap 10 k is then pulled upward across the left shoulder 124 k (FIG. 28) and then downward and rightward across the posterior side of the trunk 128 k of the patient (FIG. 29). The retainer end portion 14 k of the strap 10 k is then pressed firmly against the layer of fabric on the outside of the main portion 16 k of the strap 10 k to form a loop which extends around the left shoulder 124 k and a portion of the trunk 128 k of the patient.
When the strap 10 k is pulled downward, in the manner indicated by the arrow in FIG. 29, force is transmitted to body tissue disposed beneath the strap. This tension force may be utilized to urge one or more bones in the shoulder 124 k of the patient into a desired relationship. The tension force is also transmitted through the layer of foam on the inside of the strap 16 k to superficial fascia and deep fascia which are disposed in the patient's body near the strap.
If desired, a second strap may be connected with the strap 10 k. The second strap may be provided with two retainer end portions, corresponding to the retainer end portion 14 of FIGS. 2 and 4 and no base end portion, corresponding to the base end portion 12. One of the retainer end portions of the second strap may be connected to the anterior portion of the loop around the right arm 102 k of the patient and extend across the right shoulder 122 k of the patient to the main portion 16 k of the strap 10 k which extends across the trunk 128 k of the patient in a transverse plane. Of course, the second strap could be connected with the first strap 10 k in a different manner if desired.
In the embodiment of the invention illustrated in FIGS. 28 and 29, a single strap 10 k is utilized. However, a plurality of straps could be utilized if desired. One of the straps could be wrapped around the upper portion of the right arm 102 k of the patient and the other strap could be wrapped around the upper portion of the left arm 104 k of the patient. The two straps could be interconnected at a central portion of the trunk 128 k of the patient. The use of the straps may be particularly advantageous when treating a fractured clavicle or other bone in either or both of the shoulders of the patient.
If desired, a single, relatively long strap could be provided to form loops around both shoulders 122 k and 124 k of the patient. Each loop of the two loops would extend around one of the shoulders of the patient in the same manner as in which the strap 10 k extends around the left shoulder 124 k of the patient in FIGS. 28 and 29. The base end portion of the strap may be positioned at any desired location on the patient, for example, on top of the right shoulder 122 k. The single long strap would then be wrapped around the right shoulder 122 k for one or more turns and around the left shoulder 124 k for one or more turns. The retainer end portion may then be connected with the layer of fabric on the main portion of the strap.
The strap 10 k which extends around one shoulder 124 k, a plurality of straps which extend around both shoulders 122 k and 124 k, or a single long strap which extends around both shoulders may be utilized to position modality and/or a monitor relative to the body to the patient. The modality may include a magnet, electrical stimulator, monitor or ice pack. The use of the strap 10 k or a plurality of straps may be advantageous in holding a monitor, such as a heart monitor, relative to the body of the patient.
Use of Strap—FIGS. 30 and 31
In the embodiment of the invention illustrated in FIGS. 1-5, the only foam which is exposed on the outer side 20 (FIG. 1) of the strap is the foam on the base end portion 12 of the strap. The layer 28 of fabric extends across the outer side 20 of the main portion 16 and retainer portion 14 of the strap 10. In the embodiment of the invention illustrated in FIGS. 30 and 31, foam is exposed at two locations on the outer side of the strap, that is, at the base end portion and at a location on the main portion of the strap. Since the embodiment of the invention illustrated in FIGS. 30 and 31 is generally similar to the embodiments of the invention illustrated in FIGS. 1-23, similar numerals will be utilized to designate similar components, the suffix letter “m” being added to the numerals of FIGS. 30 and 31 to avoid confusion.
A strap 10 m is wrapped around a portion 220 of the patient's body. A second strap 224 is connected with the first strap 10 m at an intersection 200 m. The two straps may extend around any desired portion of a patient's body.
In accordance with a feature of this embodiment of the invention, a foam section 228 (FIG. 31) is provided at the intersection 220 to interconnect the straps 10 m and 224. The section 228 of foam is fixedly secured to the layer 28 m of fabric of the strap 10 m at a main portion 16 m of the strap 10 m. A layer 34 m of foam on a main section 16 m of the strap 224 engages the section 228 of foam. The relatively high coefficient of friction between the surfaces of the layer 34 m of foam on the strap 224 and the section 228 of foam on the strap 10 m results in a secure connection between the two straps.
The strap 10 m has a layer of foam 34 m which engages skin 60 m on body tissue 174 m. The layer 34 m of foam is fixedly connected to the layer 28 m of fabric. The strap 10 m is provided with a base end portion (not shown) corresponding to the base end portion 12 of the strap 20 (FIGS. 1, 2 and 5). In addition, the strap 10 m is provided with a retainer end portion corresponding to the retainer end portion of the strap 10 (FIGS. 1, 2 and 4).
Unlike the strap 10 of FIGS. 1-5, the strap 10 m (FIG. 31) is provided with a section 228 of foam which is secured to the outer side of the layer 28 m of fabric. The section 228 of foam may be secured to the layer 28 m of fabric in any desired manner. For example, by the use of adhesive and/or heat staking. The section 228 of foam may be provided with its own separate backing layer of fabric, that is, with a layer corresponding to the layer 28 m of fabric. Alternatively, the section 228 of foam may be bonded directly to the layer 28 m of fabric.
If the section 228 of foam is formed with its own backing layer of fabric, the section 228 would be connected with the strap 10 m by heat staking the section of foam and its associated backing layer of fabric to the main portion 16 m of the strap 10 m. The backing layer of fabric connected with the section 228 of foam would be disposed in abutting engagement with the layer 228 m of fabric on the main section 16 m of the strap 10 m. However, due to the relatively low coefficient of friction between the two layers of fabric, the section 228 of foam and its backing layer would be fixedly connected with the main portion 16 m of the strap 10 m by suitable fastening, such as heat staking
In the embodiment of the invention illustrated in FIGS. 30 and 31, a second strap 224 engages the section 228 of foam on the strap 10 m. However, the section 228 of foam could be disposed on the strap 10 m at a location where a portion of the strap 10 m is overlapped by another portion of the strap 10 m. Thus, the section 228 of foam could be used to provide an anchor at an intersection between sections of a single strap 10 m.

CONCLUSION

The present invention relates to a new and improved strap 10 and method of using the strap for treatment of a patient. Base and second end portions 12 and 14 of the strap 10 may be interconnected by a main portion 16 of the strap. The base end portion 12 of the strap 10 may have opposite sides 48 and 50 with surfaces which are formed of foam. The main portion 16 of the strap may have a first side 22 with a surface 31 which is formed of foam 34 and a second side 20 with a surface 26 which is formed of fabric 28. If desired, the surfaces formed of foam could be formed of a different material. A retainer 38 may be connected with the second end portion 14 of the strap 10 to connect the second end portion of the strap with the main portion 16 of the strap.
When the strap 10 is to be utilized to treat a patient, a layer 34 formed of foam disposed on the first side 22 of the strap 10 may be placed in engagement with skin 60 on the body of the patient. The base end portion 12 of the strap 10 is retained against movement relative to the body of the patient by wrapping the strap 10 around a portion of the body of the patient and positioning a portion of the layer 34 formed of foam on the first side 22 of the strap in engagement with foam disposed on the second side 20 of the base end portion 12 of the strap. The second end portion 14 of the strap 10 may be connected with a fabric layer 28 which forms the second side 20 of the strap.
If desired, a plurality of straps 10 g, 120 g and 136 may be utilized in the treatment of the patient. At least some of these straps 10 g, 120 g, and 136 may have a layer 34 of foam disposed on a first side of the strap and layer 28 of fabric disposed on the opposite side of the strap. The layers 34 of foam on the first side of the straps may be positioned in engagement with the skin of the patient and the straps may be interconnected. Interconnecting of the straps may be performed by engaging foam on the second side, that is the fabric side, of a strap with the layer of foam on the first side of a strap. A retainer 38 which, for example, may be a hook and loop type fastener, may be provided to connect an end portion of one strap with a layer 28 of fabric on another strap or with a layer of fabric on the one strap.
It is contemplated that a strap 10 constructed in accordance with the present invention may be utilized during the treatment of many different portions of a patient's body. For example, the strap may be utilized in conjunction with treatment of an arm, hand, leg, foot, shoulder, or other portion of a patient's body. A single strap 10 may be wrapped around one or more portions of a patient's body. Alternatively, a first strap 10 g may be wrapped around one portion of a patient's body and a second strap 136 connected with the first strap and wrapped around another portion of a patient's body.
The strap 10 may be utilized to apply force to deep fascia such as myofascial tissue. Of course, the strap 10 may also be used to apply force to superficial fascia. It is contemplated that one or more of the straps 10 may be used to increase a patient's proprioception. The straps 10 may also be utilized to effect shifting of a bone, such as a patella, in the body of a patient. The straps 10 may be used to connect one or more treatment devices, such as a magnet, electrical stimulator, monitor, or ice pack, with a patient.
