A lift chair includes a lift mechanism that maintains a continuous seating position during forward and elevated movement by supporting the occupant's seat, arms and back. The mobile section of the chair will also lower the occupant to the normal seating height. The gel cushion seating surface is attached at least to the moveable section of the lift chair. The gel cushion seating surface of the chair has a plurality of gel cushion cylinders arranged in a grid that provide a rhythmically changing support area at multiple points on the occupant's buttocks and thighs. This provides a comforting massage which reduces stress on the body associated with prolonged seating.

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.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the heart of an individual to a first height relative to a lower body of the individual. The lower body may be in a substantially horizontal plane. The method may also include elevating the head of the individual to a second height relative to the lower body of the individual. The second height may be greater than the first height. The method may further include performing one or more of a type of CPR or a type of intrathoracic pressure regulation while elevating the heart and the head. The first height and the second height may be determined based on one or both of the type of CPR or the type of intrathoracic pressure regulation.

A massage device includes a base, a drive unit, and a transmission unit. The drive unit is coupled to the base. The transmission unit is disposed at one side of the base. The drive unit includes a drive member to drive a rotary shaft for driving massage members. One end of the rotary shaft is provided with a unidirectional bearing and a first bevel gear. The unidirectional bearing is able to control the rotation of the first bevel gear. The transmission unit includes two positioning blocks and a worm shaft connected between the two positioning blocks. The worm shaft is provided with a second bevel gear and a movable member thereon. The first bevel gear meshes with the second bevel gear. When the first bevel gear is rotated, the second bevel gear is driven to link other parts so that the drive unit can slide on the base.

The present invention is generally directed to corrective spinal traction systems and methods. It is further directed to use of such spinal traction systems to treat various medical problems associated with abnormal spinal curvature. In one aspect, the present invention is directed to a spine corrective traction system. The system comprises an overhead system allowing a patient's spine to be pulled in every and any vector the human spine moves in three dimensional space, and in two to three planes simultaneously. It further includes a seat assembly that allows for a patient to be seated upright, supine and every angle and vector between 90 degrees upright and 0 degrees horizontal.

A primary object of the present invention is to provide an air bag and a massage machine which can allow a person to select one of an appropriate pressure massage and an appropriate massage with an air bag. An arm air bag portion 600 includes base bodies 610, 620 each containing a frame and a resin molding product, one or more protruding portions 630 for pressure provided on the base bodies 610, 620 and one or more expansion and contraction bags 640, 650, 660, 670, 690 provided on the base bodies 610, 620 and provided around the one or more protruding portions 630 for pressure. An expansion height of each of the one or more expansion and contraction bags 640, 650, 660, 670, 690 is higher than a protruding height H of each of the one or more protruding portions.

A seat having a backrest and a seat cushion includes rows of adjusting elements, respectively, which adjusting elements are arranged above one another, on both sides of the longitudinal center plane of the seat. By alternately applying the adjusting elements mutually arranged in a vertically staggered manner in the two halves of the seat, a rotational movement can be actively applied to a seat user's back and possibly pelvis, which rotational movement corresponds to the rotational movement of the back, and possibly of the pelvis, when walking.

There is provided a walker apparatus having a pair of spaced-apart, upright frame members. The walker apparatus includes a seat operatively connected to the upright frame members. The walker apparatus has a backrest cantilevered from the frame members. The backrest has at least one opening extending therethrough for permitting a user's vision past the backrest when the user grips the upright frame members.

Disclosed are devices and methods for mitigating insulin resistance in a human subject by contacting one or more regions of the neck, the supraclavicular, and the interscapular regions of the human subject with a part of a cooling device, wherein the part of the cooling device has a temperature at about 15 or less Celsius degrees; cooling the one or more regions of the neck, the supraclavicular, and the interscapular regions of the human subject for a cooling period of at least 15 minutes; and performing previous two steps daily for about 14 or more days. The devices and methods may also be used to preventing, delaying or treating type 2 diabetes in a human subject or activating brown fat without incurring a sympathetic nerve-mediated cold feeling in a human subject.

The present invention is an apparatus and method for use in a treatment for prevention of arthrofibrosis that includes a first and a second substantially L-shaped frames, each L-shaped frame having a first member and a second member extending from the first member in a substantially perpendicular direction and terminating in a first end, a fixed plate extending between the first members of the L-shaped frames, the fixed plate being parallel with the first members of the L-shaped frames, a movable plate pivotally coupled to the first ends of the first members of the L-shaped frames with, a pneumatic piston coupled to the movable plate and the fixed plate, a hand operated valve operatively coupled to the pneumatic piston and a goniometer coupled to the movable plate and one of the L-shaped frames, the goniometer adapted and configured to indicate the angle between the movable plate and the fixed plate.
