A traction apparatus develops a pull force through some or all the compressed joints of the ankles, the knees, the hips and the vertebrae of an individual, after the individual attaches to the ankles, or the waist, or the shoulders, a harness connected to suspended weights, and then positions self to rest supine over an inclinable, full length frictionless surface of full-width idler rollers, and inserts self's head's occipital portion into a crescent shaped hollow head restrainer which arrests the body's pull by the weights.

An apparatus for self-administering therapeutic pressure to provide chiropractic treatment to a user comprising a first and second side rails; wherein the first and the second side rails are parallel to each other, further the side rails comprises a fixable telescopic arrangement to fixedly adjust length of the side rails; a font cross rail, wherein the font cross rail acts as a thrust vector to provide desired pressure by the user; a back cross rail comprising at least one acupressure tip aligned substantially parallel to the side rails, wherein first and second side rails, the font cross rail and the back cross rail form a closed frame, whereby the adjustable side rails provide fixable adjustment of the frame depending on the user's needs. An upper cross rail, wherein the upper cross rail further comprises first padded upper rest points to act as a fulcrum between the font cross rail and the acupressure tip during the chiropractic treatment to a user's lower spinal area, whereby desired therapeutic pressure is self-administered by the user to provide chiropractic treatment to various body areas through the acupressure tip. In the preferred embodiment, this is through the use of the hoop formed by the rails that extends around the body and is held in front of the self-treating person, with the angles of the side rails extending down the side presenting a ready measure of the angle of the treating instrument on the spine.

A passive range of motion device is disclosed. The passive range of motion device is configured to deliver passive rotational motion to a joint, such as a hip joint. Although the use of passive range of motion devices to deliver postoperative physical therapy to hip or shoulder joints is widespread, these devices deliver motion therapy in only one plane. The hip and shoulder joints, however, allowing motion of the leg or arm in multiple planes. A device for delivering passive range of motion therapy in multiple planes to a joint, such as a hip joint or a shoulder joint, is described. The device may have a processing unit for storing user information and device status information. The device may be controlled by a controller attached to the device, or remotely, such as by a remote desktop computer or a mobile computing device.

A hip component for a legged mobility device has a hip body, and a hip insert assembly for adjusting a size of the hip component. The hip insert assembly includes a carrier assembly mounted to the hip body, and a main insert assembly spaced apart from the carrier assembly. Adjustment screws are connected to the carrier assembly and the main insert assembly. The carrier assembly includes an adjustment mechanism including a drive shaft and an adjustment chain to effect translational movement of the adjustment screws to move the main insert assembly to adjust both width and depth of the hip component simultaneously. The hip component includes an abduction/adduction control mechanism that includes elastomeric bushings that are selective as to resistance level and shape to control a degree of abduction and adduction, and to preset an initial angle. A leg component includes a central carrier, and first and second housings that are located on opposite sides of the central carrier. An adjustment mechanism including a drive shaft that drives driven shafts, such as by a worm/worm gear interaction, effects movement of the first housing to relative to the second housing to adjust a length of the leg component.

A joint actuator assembly incudes a motor, a rotating driving member driven by the motor for driving a driven component, and a transmission assembly located between the motor and the rotating driving member that provides speed reduction from the motor to the rotating driving member. The rotating driving member includes a magnetic/electrical coupling comprising a magnetic coupling component configured to magnetically couple with an opposing magnetic coupling of the driven component, and an electrical element configured to provide an electrical connection to an opposing electrical element of the driven component. The actuator and driven component may be combined into a mobility device including a magnetic/electrical coupling system comprising a first magnetic/electrical coupling on the actuator assembly that magnetically and electrically couples to a second magnetic/electrical coupling on the driven component. The magnetic coupling system includes a plurality of magnetic elements located on the first and/or second magnetic/electrical couplings and opposing electrical elements for electrical connection when the actuator assembly and the driven component are joined together.

A joint actuator assembly for a legged mobility device includes a motor that drives a joint connector for driving a joint of the mobility device, and a three-stage transmission of speed reduction to result in a high torque, low speed output. The first stage may include a small sprocket mechanically connected to the output shaft of the motor, and a large sprocket driven by a cable chain to provide the first speed reduction. The second stage may include a small central helical gear mechanically connected to the first stage output, and two opposing larger first and second outer helical gears that mesh with the central gear to provide the second speed reduction. The third stage may include a cable reel assembly including an output reel and a cable element that interconnects the output of the second stage and the output reel to provide the third speed reduction.

A rolling walking device for a person with a disability may comprise: a plurality of rollers, at least one support apparatus for the person, wherein the at least one support apparatus is configured so that the person while using the rolling walking device can sit on the at least one support apparatus and simultaneously rest with a front side of their upper body at least partially on the at least one support apparatus with their hip joint flexed.

The device and methods disclosed herein allow an individual to create and sustain a differential stretch to the anterior muscles and ligaments of the torso, hips, and legs. The device includes a base frame, a vertical member secured to the base frame, a rotational lift lever secured to the vertical member at a vertical pivot member, a lower extremity elevation member secured to the rotational lift lever, and at least one lower extremity attachment device secured to the lower extremity elevation member. In methods of use, the device lifts an individual's legs off the ground, while the person is lying face down, to create a stretch in the anterior muscles, fascia, or ligaments. The device has various planes of rotation, which allows for differential stretching in the various quadrants of the person's torso. The device is height adjustable and displaceable along a track to accommodate different body types.
