An intramuscular stimulation needling device for chronic pain relief. The needling device can include a stepper motor, a needle, and a control unit. The needle can poke an affected muscle tissue and driven by a stepper motor in reciprocating manner. In each cycle, the needle moves a pre-determined distance forwardly in a first half cycle and retracts to original position in a second half cycle. The control unit can accelerate of the needle one or more times in the first half cycle at spaced intervals and decrease the velocity in the reverse pattern in the second half cycle.

Among other things, in one aspect, we describe a system for assisting with cardiopulmonary resuscitation (CPR). The system includes at least one sensor; and one or more processors configured for calculating a chest compliance relationship based on data received from the at least one sensor, and determining a neutral position of chest compression based at least in part on a feature of the chest compliance relationship. The system can take the form of an active compression-decompression 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.

massage mechanism and a massage control device thereof, a massage machine and a working method of the massage mechanism are disclosed. The massage mechanism includes a transmission part that is rotatably connected to a first transmission arm, a second transmission arm connected to the first transmission arm, and a swing rod connected to the second transmission arm. Each of two ends of the swing rod is provided with a massage wheel. A swing mechanism is mounted on the second transmission arm, is in contact with the swing rod and is configured to drive the swing rod to swing. The swing rod is driven to swing back and forth through the swing mechanism; the massage wheels on the swing rod massage the person being treated in a “knocking” manner; and the speed of the speed reducer and the swing amplitude of the swing rod are adjustable.

A finger motion rail is provided for a therapy device for carrying out passive and/or actively-assisted motion of the fingers and thumb of the hand. The therapy device has an upper shell, to which a kinematic motion mechanism of the finger motion rail for each selected finger is connected, each mechanism has a motion drive that is in control engagement with a control system. The kinematic motion mechanism of the finger motion rail, which mechanism has a carriage that moves in a rail provided around the metacarpophalangeal joint and a pivoting lever, is located at the side of each finger for the passive and/or actively-assisted motion of the selected fingers. This allows an individual finger motion rail with the kinematic motion mechanism to be provided for each selected finger, the rail being located at the side of each finger, thus permitting each selected finger to bend and/or stretch without constraint.

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.

An adjustable stroke length percussion massage device includes a stroke arm connected to a piston which is connected to a massage tool for providing a massage to a user. The stroke arm is secured to a crank pin of a crank mechanism which includes a rotatably connected crank housing and crank base, the crank pin being movably secured between the crank housing and crank base such that the crank pin moves from a first end to a second end of a sliding groove located in the cam housing when a rotation direction of the single unit is reversed by a motor. When the crank pin is moved from the first end to the second end of the sliding groove, a stroke length of the piston is changed.

This body balance correcting apparatus is capable of improving blood circulation, skeletal balance and the like from the inside of the body by oscillating the body of a user, and includes an oscillation panel which supports the user in a recumbent position, a support device which supports the oscillation panel so as to enable the oscillation panel to oscillate in the in-plane direction, a drive device which oscillates the oscillation panel in the axial direction of the body of a user, and a controller which controls the acceleration and deceleration of the oscillation by the drive device. The oscillation panel can be adjusted to oscillate at an amplitude in the horizontal direction with respect to the support device in a range of about 0 to 6 cm and within 15 cm and with a cycle in a range of about 0.5 to 2.0 seconds, and by adjusting the acceleration and deceleration of the oscillation of the oscillation panel by the control order from the controller, blood circulation and skeletal balance can be improved from the inside of the body of the user.

A device performs a flexion process or an extension process with respect to a knee joint. The device includes a support frame extending in a longitudinal direction. A flexion system includes a foot support assembly configured to translate relative to the support frame in the longitudinal direction thereof and a flexion linear actuator configured to cause the translation of the foot support assembly. The extension system an extension pad assembly including a first expansion pad configured to engage an upper surface of the leg at a position above the knee joint and a second expansion pad configured to engage the upper surface of the leg at a position below the knee joint. An extension linear actuator is configured to translate the extension pad assembly with respect to the transverse direction. A power system is configured to selectively actuate each of the flexion linear actuator and the extension linear actuator.
