An agility trainer apparatus that provides a robotic system that applies forces laterally to a harness worn by a person during walking so as to provide highly controllable interventions targeting locomotor stability.

Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

A method to treat a dry eye condition of an individual, includes: receiving a switch signal generated based on a manipulation of a control switch at a handheld device; and activating a motor in response to the switch signal to oscillate a member at an oscillation frequency, the member having an elongated configuration, and having a portion for placement outside the individual; wherein the oscillation frequency is sufficient to induce tear production when the portion of the member is applied towards a surface of a body portion of the individual.

A hands-free wearable cardiopulmonary resuscitation (CPR) device, comprising a wearable belt, an electrical motor mounted on the wearable belt, a piston housing coupled to the wearable belt, and a heartbeat sensor electrically coupled to the electrical motor is provided. The piston housing encloses a piston that is moveably coupled to the electrical motor. The heartbeat sensor is configured to detect an absence of a heartbeat on a user and to responsively activate the electrical motor. The electrical motor is configured to drive the piston to move between upward and downward directions along the piston housing to produce chest compressions on the user in response to the electrical motor being activated by the heartbeat sensor.

Disclosed is a massage chair with improved stretching performance. The massage chair includes a seating unit (20); a backrest unit (10) with a pair of massage rollers (40) installed to left and right sides thereof; a footrest unit (30) or an ankle holder (33) provided to a front lower portion of the backrest unit (10) to hold both feet; and an upper body stretching unit (50) installed to a rear portion of the backrest unit (10) to lift a hand lever (51) by a driving force, in which when the hand lever (51) is lifted in a state in which a user holds the hand lever (51) by both hands, the whole body is stretched. The lower portion of the backrest unit (10) is optionally provided with a lumbar stretching unit (70) for stretching a waist of the user, and an air conditioner (460) for supplying air to the backrest unit (10), so that the user can get over feeling tired.

A massage roller assembly that includes an outer roller surface and a plurality of vibration motors positioned adjacent to the outer roller surface that are configured to transmit vibrations to the outer roller surface. The vibration motors are individually controllable such that at least first and second sets of vibration motors can be switched on and off individually.

A joint exoskeleton auxiliary driving mechanism has a first driving module. The first driving module has a first gear member, a first connecting member, a first rotating driver, a first linear driver, and a first motion element. The first connecting member is disposed on a side of the first gear member. The first rotating driver is disposed on the first connecting member and engages with the first gear member. The first linear driver is disposed on the first connecting member. The first motion assembly is connected to a first power output element of the first linear driver. The joint exoskeleton auxiliary driving mechanism has two degrees of freedom motion function such as forward rotation, reverse rotation, and dorsiflexion or extension, and has the advantages of structural simplification, precise strength controlling, lightweight, and miniaturization.

A lower limb training rehabilitation apparatus, comprising a weight reducing device, a pelvis supporting device, an exoskeleton device, a control system for controlling mechanical movements of the rehabilitation apparatus, and a treadmill used for walking of a patient. The rehabilitation apparatus hoists the upper body of the patient by means of the weight reducing device, then fixes the crotch of the patient to the pelvis supporting device, and fixes two legs of the patient to two mechanical legs of the exoskeleton device. A power source drives the pelvis supporting device to move up and down, so that the patient can move in the vertical direction; in addition, a sliding base of the pelvis supporting device can assist the patient in moving left and right, swinging left and right, and twisting. The mechanical legs and the treadmill together implement arbitrary movements in six degrees of freedom of the patient.

Mobility rehabilitation device comprising a table, hinged to a support structure and respective actuator, configured to rotate said table between a horizontal and a vertical position, said table being provided with a harness configured to fasten a patient positioned thereon, said rehabilitation device comprising a lower limbs movement mechanism to make the patient's femur rotate with respect to the hip and a couple of feet movement platforms, said device comprising also a plurality of infrared light sources, positioned so that each light source lights up the muscles of a respective area of the patient's lower limbs, a control unit configured to control said lower limbs movement mechanism and said light sources and to manage an adjusting cycle of the intensity of said light sources in a differentiated manner for each of said sources, as a function of the movement cycle imposed by said lower limbs movement mechanism.

A programmable range of motion system has a frame, a range of motion device, a controller, a computer and sensors. The frame has a seat to support a rehab patient. The range of motion device is attached to the frame. The actuator, servo or alternate mechanism selectively rotates the range of motion device through a range of motion for a rehab patient's limb. The controller controls the actuator, servo or alternate mechanism. The computer is connected electronically to the controller. The computer has a software, program or application including a plurality of programmable range of motion movements for exercising the limb. The sensor detects movements of the actuator, servo or alternate mechanism and records data back to the computer. The term actuator as used hereafter includes servo or alternate articulating mechanism.
