[0002] In the human body, the lower back is the site most prone to musculoskeletal pain.
By some estimates, more than half of all people in industrialized countries will suffer from lower back pain LBP at some time during their active lives. Lumbar disc herniation (LDH) is a frequent cause of LBP, but not the only cause. Conservative treatment often involves resting, drug therapy exercise, manipulation, epidural injections, and/or bracing. Traction of the upper body may also be applied to decrease disc protrusion, reduce compression of joint surfaces, stretch soft tissues, and stimulate renewed growth of joint tissues. Types of traction include continuous, static and intermittent traction, which may be applied by gravity, or by manual, aquatic, mechanical, and motorized means. Similar means of traction have also been applied to joints of the body, such as elbows and knees. id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3"
id="p-3"
[0003] U.S. Patent 4995378 to Dyer et al., "Therapeutic table," describes a therapeutic table for applying traction to a patient's back. The table has upper and lower-body sections on which a patient lies. The table includes a pneumatic cylinder and piston for moving the lower-body section with respect to an upper-body section to increase or decrease the distance between an upper-body restraint and a pelvic belt anchor, to apply traction through the patient's arms to the lumbar region of the spine. id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4"
id="p-4"
[0004] U.S. Patent 2865387 to Sorenson, "Traction table," describes a traction table having a lower body section and an upper body section. The lower body section is moved by a vacuum piston with respect to the upper body section. Treatment is accomplished through intermittent or periodical application of traction or tension to the spinal or other sections of the body, by controlled reciprocal movements of the lower body section. id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5"

[0005] U.S. Patent 2773499 to Zur, "Hydraulically actuated intermittent drive in physical therapy apparatus," describes a hydraulically actuated intermittent drive for physical therapy having reciprocating means adapted to be connected to a patient for producing pulling and releasing movements. Zur describes stretching of the neck by placing a harness under the wearer's chin and about the back of his head as indicated in Figs. 1 and 2, or a stretching of the legs and back by reversing the position of the patient.

[0006] Embodiments of the present invention provide a system and methods for implementing a device for musculoskeletal decompression therapy for the spine and limbs of patients. Embodiments include a system (20) for musculoskeletal decompression that includes a frame (32) for supporting a patient in a supine position, having a moving top section (40) and a stationary top section (42), the moving top section (40) supported by four moving support rods (202), each rod at one end connected pivotally to the moving top section (40) and at the other end connected pivotally to a bottom bracket (206) of the frame (32). An electric motor (210) of the system includes a cam (212). A guide rod (214) is connected pivotally, at one end, to the cam (212), and at the other end connected pivotally to the moving top section (40). such that rotation of the cam (212) drives the guide rod (214) in a reciprocating motion thereby moving the moving top section (40) in a reciprocating motion that increases and decreases a gap (60A, 60B) between the moving top section (40) and the stationary top section (42). id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7"
id="p-7"
[0007] The frame (32) may further include a strap mount (28A, 28B) connected to a strap (26) that is connectable to a body section of the patient. The strap holds the body part against the strap mount (28A, 28B) with a tension that is linearly proportional to the gap (60A, 60B). The strap mount (28A, 28B) may be affixed to a linear actuator (230) and the linear actuator (230) may be configured to move the strap mount (28A, 28B) to adjust a maximum tension of the strap holding the body part. A processor (36) and control panel (38) may be included, and the processor may be configured to receive input settings entered at the control panel for moving the linear actuator and responsively to signal the linear actuator to move. id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8"
id="p-8"
[0008] A processor (36) and control panel (38) may be provided, wherein the processor is configured to receive input settings entered at the control panel determining a rate of the reciprocating motion and a length of time of treatment. The processor may be further configured to signal the electric motor to operate a the received rate of reciprocating motion and for the received length of time. id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9"
id="p-9"
[0009] The processor may also be configured to receive input indicating default settings for motion rate and session duration. The processor may be further configured to signal the electric motor to operate at the default motion rate and for the set length of time when subsequent input settings are not received. The default rate may be set to 24 cycles/minute and the default session duration may be set to 15 minutes.

[0019] Figs. 1A and 1B are schematic illustrations of a multifunctional decompression system (MDS) 20 , according to some embodiments of the invention. The MDS is designed to provide decompression therapy, also referred to as "traction" therapy for treatment of musculoskeletal impairments such as knee and spinal injuries. The main unit of the MDS is shown in the figures; an auxiliary device for arm decompression is not shown but may also be used in conjunction with the MDS main unit to provide traction therapy for a patient's elbow. id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20"
id="p-20"
[0020] Patients, such as a patient 22 , may be positioned on the MDS 20 in the supine position, as indicated in Figs. 1A and 1B . The figures show a patient's foot in a brace 24 , which is connected by straps 26 (typically one strap for each foot) to strap mount 28A. Strap mounts 28A and 28B are collectively indicated as strap mounts 28 . Typically, for knee decompression therapy, the strap 26 is connected to strap mount 28A , which is lower than strap mount 28B . For spinal decompression therapy, the position of the patient may be reversed, such that the patient's head is secured in the brace 24 , that is, the patient's head is positioned towards the strap mounts 28 , as described below with respect to Figs. 3A and 3B .
For spinal decompression therapy, the patient's head is typically secured with the strap connected to the higher strap mount 28B . The strap 26 may be of any flexible material, such as a cord or a cable. id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21" id="p-21"
id="p-21"
[0021] A frame 32of the MDS 20 includes cover panels 34 , which cover internal moving parts that are described hereinbelow. Also, mounted to the frame is a processor 36 having a control panel 38 , by which an operator may enter settings, such as motion rate and duration of operation of the MDS 20 . The processor is typically a microcontroller or other computing device, having memory storing instructions configured to receive input from the control panel. Input may include, for example, a rate of reciprocation of a moving top section 40 and a length of a treatment session. The microcontroller is programmed to signal the electric motor to operate at a cycle rate corresponding to the rate that is input, and to continue operation for the corresponding length of time setting. id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22" id="p-22"
id="p-22"
[0022] At the top of the MDS are two platform sections that form a bed on which a patient lies, the two platform sections being the moving top section 40 and a stationary (or "fixed") top section 42 . id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23" id="p-23"
id="p-23"
[0023] Affixed on each top section is a respective mattress pad, a moving mattress pad 44 mounted on the moving top section 40 , and a stationary mattress pad 46 mounted on the stationary top section 42 . Mattress pads typically have a solid base, such as a 10 mm thick plywood base. The mattress pads are typically filled with a soft foam material, such as a 100 mm thick polyurethane foam filler. The lining of the mattress pads is typically a hypo- allergenic, durable medical upholstery material such as an artificial leather material.
Additional pads, or cushions, such as a thigh brace 50 for holding a patient's thigh to the moving mattress pad 44 , may also be lined with the same upholstery material and filled with the same foam filler. The thigh brace 50 typically includes an upper brace 50A and a lower custion 50B . id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24" id="p-24"
id="p-24"
[0024] A spring scale 72typically connects the strap 24 to the strap mounts 28A or 28B .
The spring scale 72is typically configured with a visual scale to indicate tension applied to the patient. id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25" id="p-25"
id="p-25"
[0025] During decompression treatment, the moving top section moves towards and away from the stationary top section, in a reciprocating, periodic motion of typically 10- times per minute (e.g., 24 cycles/minute), and with a range of motion that may be, for example, 6 cm. To configure the system for a given patient, the patient lies on the MDS with the moving top section set at its maximum point of separation from the stationary top section, indicated in Fig. 1A as a maximum gap 60A . Strap 24 is then affixed to the patient's foot (or head, as described below) and a strap mount adjustment rod 74 is extended away from the MDS until a reading on the spring scale indicates the desired maximum tension, for example, kg. Given that this is the tension at the maximum separation of the top sections, the tension will drop as the top sections are brought together, until reaching the minimum gap of separation, indicated as minimum gap 60B in Fig. 1B . That is, during each cycle of separation and closure of the top sections, the maximum tension reached is the tension set initially. The tension at the minimum separation is typically zero. id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26" id="p-26"

[0026] The typical maximum tension set by an operator ranges from 2 to 7 kg., depending on the level of pain and discomfort. id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27" id="p-27"

[0027] Figs. 2A and 2B are schematic illustrations of the MDS 20 for knee decompression, with the cover panels 34 removed, according to some embodiments of the invention. Fig. 2A shows the moving top section 40 at its maximum point of separation, showing a maximum gap 60A , as in Fig. 1A . Similarly, Fig. 2B shows the moving top section 40 at its minimum point of separation, showing a minimum gap 60B , as in Fig. 1B . id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28" id="p-28"

[0028] The moving top section 40 rests on moving support rods 202 , which typically comprise two or more pairs of support rods, each support rod 202 having a bottom end connecting by a pivot 204 to a bottom bracket 206 of the MDS frame 32 , and a top end connecting to the moving top section 40 at a pivot 208 (as shown in the blow-up section of Fig. 2B ). Because the moving top section is supported by moving support rods, rather than being supported on a rail, there is less mechanical degradation over time, as a rail can accumulate dirt that is difficult to access and therefore difficult to clean. id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29"

[0029] An electric motor 210has a cam 212that drives a guide rod 214 . One end of the guide rod 214 is connected to the moving top section 40 at a pivot point 216 . The other end of the guide rod 214 is connected to the cam 212 off center, such that as the cam rotates, the guide rod 214moves the moving top section 40 back and forth. id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30" id="p-30"
id="p-30"
[0030] The moving and stationary parts of the MDS are typically made of durable materials, such as welded, carbon steel profiles, coated with powdered enamel. id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31" id="p-31"
id="p-31"
[0031] The electric motor 210 is typically mounted on the MDS with rubber-metal shock absorbers, reducing vibration transmitted from the engine and providing dielectric insulation of the stationary frame. The MDS may also be equipped with an emergency shut-down button, connected to the control panel by a cable. id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32" id="p-32"
id="p-32"
[0032] In some embodiments, the MDS 20 may include a linear actuator 230 , which may also be controlled by the operator from the control panel 38 and which, when operated, moves the strap mount adjustment rod 74 to an extension distance that achieves the desired maximum tension (e.g., 5 kg.). As described above, the maximum tension is set by an operator when the separation gap is at its maximum. As the separation gap closes during reciprocating motion of the moving section, the tension declines, typically to zero. id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33" id="p-33"

[0033] Figs. 3A and 3B are schematic illustrations of mechanical elements of the MDS for spine decompression, according to some embodiments of the invention. As shown in Figs. 1A and 1B , while the MDS is operating to provide knee decompression, the upper torso of the patient, including the patient's thighs, are resting on the moving top section, with the thighs secured by the thigh brace 50 . As shown in Figs. 3A and 3B , while the MDS is operating to provide spine decompression, the patient is reversed, such that the patient's lower body and thighs are resting on the moving top section, with the thighs also secured by the thigh brace 50 . That is, for knee decompression, the thigh and upper body move, with tension applied by the strap 26 to the patient's leg. For spine decompression, the patient's thighs and legs move, with tension applied by the strap 26 to the patient's head (which in turn applies tension to the patient’s upper body). In addition, for spine decompression, the patient’s chest is typically bound to the stationary top section 42 by a thoracic brace or by thoracic straps (not shown), which are connected to a thoracic mount 300 . The patient is initially positioned on the top sections when the top sections are closed, that is, when there is a minimal gap between the moving and stationary top sections. The patient is then bound to the thigh brace 50 and to the thoracic mount 300 (which typically binds the patient’s chest and arms). An initial, small tension is then applied to the spine by opening the top sections to the maximum gap, the tension being relatively small because of the flexibility of the thigh brace cushions and of the thoracic brace or straps. Subsequently, additional tension is applied by adjusting the tension on strap 26 , as described above, and the reciprocating operation of the MDS is then initiated. id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34" id="p-34"

[0034] Fig. 4 is a schematic, isometric illustration of mechanical elements of the MDS frame 32 , according to some embodiments of the invention. The illustration shows the moving top section 40 is supported by support rods 202 having a bottom end connecting to a bottom bracket 206 of the MDS frame 32 . The cam 212 of the electric motor is shown connected by the guide rod 214 to the moving top section 40 . The connection is typically set at the pivot 216 , as described above. id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35" id="p-35"
