A buoyancy-based cervical traction system has a floatation and a head rest supported by the flotation system. The head rest is adapted to support a person's head above the neck and apply traction to the neck when the person is in a body of liquid. The system has a position adjustment system adapted to allow selective adjustment of the position at which the person's head rest will be relative to an upper surface of the liquid when the person and the cervical traction system are in the liquid, the person's head is supported by the head rest, and the cervical traction system and person are floating in the liquid at equilibrium.

A hip traction device and associated methods is disclosed. Such a device may include a base having a proximal end and a distal end, a guide coupled to the base, a carrier configured to move along the guide, a tensioner coupled to the base and configured to provide a force to the carrier to move the carrier toward the distal end of the base, causing a leg to be put in tension, and a single body coupling mechanism being removably attached to the carrier and being configured to securely attach to a lower portion of a leg when the body coupling mechanism is detached from the carrier.

A cervical traction device is provided. A frame presents an anterior support under the maxilla of a user, while a posterior support is applied to the lower portion of the occiput of the user. Thus, pressure is avoided on the potentially unstable mandible, and the lower and upper teeth are not compressed against one another. A series of suspension points on the frame allows the angle at which traction may be applied to the cervical vertebrae to be varied.

Provided are a method for providing a massage to stimulate a growth plate for promoting growth and a massage apparatus. The massage apparatus includes: a body data calculation unit for calculating length related information of at least a portion of a body part of a user; a growth plate stimulation massage pattern determination unit for determining a growth plate stimulation massage pattern on the basis of the calculated body length related information; and a growth plate stimulation massage providing unit for providing a massage on the basis of the growth plate stimulation massage pattern.

A three-dimensional spine correction robot includes: a pillar, a seat, human body fixing belts, a head fixing apparatus, a bracket, pillar casing pipes, a spine lateral push-and-pull apparatus and a seat locking mechanism. The head fixing apparatus is fixed on the top of the bracket. The pillar casing pipes are movably sleeved over the pillar, and each pillar casing pipe is connected to a human body fixing belt. The lower end of the pillar casing pipe is connected to the seat, and the upper end is connected to the pillar. A first elastic connection object is connected between the pillar casing pipes. The spine lateral push-and-pull apparatus may move up and down along the pillar and swing. The seat is connected to the pillar through a bearing, and may move up and down along the pillar. The seat locking mechanism is fixed between the bracket and the seat.

A chair may include a base defining a vertical axis of the chair, a seat configured to support a user thereon, and a seat support assembly disposed between the base and the seat in the direction of the vertical axis. The seat support assembly may include a height adjustment assembly configured to allow the seat to translate along the vertical axis, and a wobble assembly configured to allow the seat to tilt relative to the vertical axis in a side-to-side direction. The wobble assembly may include a wobble lock having a locked configuration, in which the wobble lock inhibits tilting of the seat relative to the vertical axis in the side-to-side direction, and an unlocked configuration, in which the wobble lock allows tilting of the seat relative to the vertical axis in the side-to-side direction.

Apparatus (60) for supporting a subject (2) in an inverted state comprises a ground engaging plinth (8) and a support platform (12) pivotally coupled to the plinth (8) about a first pivot axis (15) so that the support platform (12) is pivotal between a first state with a subject (2) in a supine state on the support platform (12) and a second state with the subject (2) inverted on the support platform (12). The subject is supported in the inverted state on the support platform (12) by shoulder engaging elements (24), and is secured to the support platform (12) by a torso strap (35). A foot engageable element (77) connected to a weight carrying bar (84) through connecting members (79,82) extending through an elongated slot (80) in the support platform (12) allows leg and abdominal muscles to be exercised by urging the foot engageable element (77) in the direction of the arrow A against weights (85) carried on the weight carrying bar (84). A carrier element (81) slideable on a guide bar (83) guides the foot engageable element (77). Handgrips (86) are connected by steel cables (87) around pulleys (88,89,90,91) to the weight carrying bar (84) for facilitating exercising of arm, shoulder, chest and back muscles.

A tilting inversion exerciser includes a supporting stand having a primary frame and an auxiliary frame, one or two carriers pivotally attached to the supporting stand with apex members, a supporting table attached to the carriers and movable relative to the carriers, the carrier includes a guiding device for guiding the supporting table to move relative to the carrier and the apex member, and a spring biasing member is engaged between the carrier and the supporting table for adjusting a center of gravity of the carrier relative to the supporting table when users of different weight is engaged onto the supporting table and for giving some security to the user while conducting the inversion exercises.

Portable devices and methods for preventing deep vein thrombosis (DVT) by assuring that the ankle is flexed and extended sufficiently to promote blood flow in the lower leg are disclosed. The device includes an actuator with a free movement mode that allows a patient to move freely between activations or to initiate movement to delay a next automatic activation.

A hip traction device, system, and associated methods are disclosed. Such a device may include a base having a proximal end and a distal end, a guide coupled to the base, a carrier configured to move along the guide upon receiving a force from a tensioner to move the carrier toward the distal end of the base, causing a leg to be put in tension, and a single body coupling mechanism either removably attachable or permanently attached to the carrier and configured to securely attach to a lower portion of a leg, such that the portion of the leg moves with the carrier during operation of the tensioner.
