A knee rehabilitation machine with multi-position synchronous force application includes a bottom box, a vertical box, and a suspension box. The vertical box is vertically arranged at an end of the bottom box, and an upper end of the vertical box is horizontally fixed with the suspension box. A pressing unit swing lever mechanism is arranged in the bottom box, and a vibration unit, a pulling unit, and a transmission mechanism of a pressing unit are arranged in the vertical box.

An air-suction, heating and vibration physiotherapeutic bar, comprises a surface cover, a bottom cover, a DC plug and at least one key. An air pump, a battery, an electronic valve, a PCBA, a motor and a massage device are installed in a space encircled by the bottom cover and the surface cover; the DC plug is electrically connected with the PCBA by a lead; one end of the bottom cover is provided with an air-suction hole; a silica gel suction nozzle of a through hole is sleeved at the air-suction hole; the electronic valve is connected with the air pump by a three-way air tube; the other end of the three-way air tube is connected with the air-suction hole. The air-suction, heating and vibration physiotherapeutic bar of the present invention has simple structure, has physiotherapeutic functions of vacuum air-suction flapping, heating and vibration massage.

A mechanical transmission, tethered actuation system, an autonomous ankle exoskeleton design and method of their use employing a cable, pulleys and associated pulley housings to change angular transmission of linear force on the cable. The pulleys are linked by a ground link and the cable is threaded across and between the pulleys, whereby rotation of either of the pulleys in one direction causes rotation of the other pulley in the opposite direction. Independently of the pulleys, the pulley housings can freely rotate about associated pulleys, and a link between the pulley housings is provided, whereby rotation of one of the pulley housings in one direction causes rotation of the other pulley housing at an equivalent angle in the opposite direction, thereby enabling a change in transmission angle of linear force on the cable threaded across and between the pulleys and the associated pulley housing essentially without resistance. When pulleys have the same angular velocity ratio as that of the associated pulley housings, there is no cable slack since the net changes in length of the cable wrapping around two pulleys is zero.

A knee joint mechanism without a power source is provided. The knee joint mechanism includes a thigh support assembly, a connecting base, a shank support assembly and a locking mechanism. The thigh support assembly is fixed at a thigh of an exoskeleton robot, a first angle sensor is disposed on a hip, and power is provided from the hip. The connecting base is mounted with a second angle sensor; the locking mechanism includes a motor, a worm gear, a locking member, an unlocking member, and a first limiting member. The unlocking member and the first limiting member firmly fix the locking member to maintain the thigh support assembly, the connecting base and the shank support assembly at an ergonomic angle; the motor drives the unlocking member to rotate through the worm gear to realize unlocking, and the second angle sensor controls the unlocking member to lock the locking block.

Bed base and bed provided with the bed base, wherein the bed base is provided with massaging apparatuses having slats which are placed one after the other and which define a support plane for a mattress, wherein the massaging apparatuses include a first drive which activates a first series of slats for a massaging action and a second drive which activates a second series of slats for a massaging action.

A device and method are provided for treating a patient with vibration and/or tactile and/or thermal stimuli. The device includes first and second stimulating units for generating first and second stimuli respectively. The stimuli are vibration and/or tactile and/or thermal stimuli, and each of the stimuli is repeated on average at a frequency of 1 to 60 Hz. The stimuli are generated partly at different times.

A body lightening system for at least partially supporting the weight of a user, the system including a structure having a frame and a motion system, the motion system driving the structure to follow the movements of the user, a holding system, the holding system including a holding mechanism, a hanger and a plurality of hanging cables, the plurality of hanging cables connecting the hanger to a harness to be worn by the user, a power system including a power source for powering the body lightening system, and a human machine interface, the human machine interface providing control over the motion of the motion system and the percentage of the user's weight supported by the holding system.

An adjustable stroke percussion massage device includes a stroke arm having a first end connected to a percussion massage head. A pin extends outward at a second end of the stroke arm. A cam has a cam slot formed into the cam such that the pin fits into the cam slot. The cam slot has a length, where the pin is movable from a first end of the cam slot to a second end of the cam slot, where the pin is a first distance from a rotation axis of the cam when positioned at the first end of the cam slot, and the pin is a second distance from the rotation axis of the cam when positioned at the second end of the cam slot. A motor is operable to rotate the cam about the rotation axis, moving the stroke arm along a vibration axis.

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.

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.
