A vibrating back massager with guide slot and vibrating heads is described. The guide slot is designed to restrict lateral movement of the massage device when the guide slot is engaged with a supporting member. The supporting member may be the edge of an open door, a corner, a vertical pole, or other generally available structure. The device includes a strap handle which may be draped over the user's shoulder and used to control the vertical position of the device. The described vibrating massage device allows a single user to create and maintain a significant amount of massage pressure without fatiguing his arms or relying on a second person. In a preferred embodiment, the controls for the vibrating massage device are incorporated into the strap handle so that the speed, intensity, and/or temperature may be controlled by the user without repositioning the device.

Provided are a support rehabilitation training robot and an operation method thereof. The support rehabilitation training robot includes a crawler-type walking machine, a pedestal, a lifting lead screw mechanism, a manipulator and a counterweight mechanism. The manipulator includes a shoulder joint, a revolute joint, an elbow joint and a wrist joint. Each of the joints includes a motor, a harmonic reducer and an output terminal.

A leg support exoskeleton is strapped on as a wearable device to support its user during squatting and/or lunging. The exoskeleton includes a knee joint connected to a first link and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatable connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.

A human motion assistance device has an upper torso harness and a preloaded leg strap arrangement affixed to the upper torso harness. The preloaded leg strap arrangement has an X-bracket connected to the upper torso harness. The preloaded leg strap arrangement further uses a plurality of blocks and a preloaded strap routed through the blocks and connected to the X-bracket. The preloaded leg strap arrangement further uses a knee pad with a split seam. The preloaded strap is under tension, even when the human motion assistance device is in a relaxed state. The preloading provides an immediate force which increases under a loaded state. The potential energy stored during the loaded state is released when transitioning from a standing position to a crouched, squatting, or seated position. The configuration allows for maximizing the energy storage without putting excess shoulder pressure on the user when standing.

Wearable systems to partially support the weight of a human user engaged in task performance in a crouched position at or near ground level are presented herein. In one aspect, the wearable systems employ passive mechanisms and the configuration of the support mechanisms is changed by movements of the body of the human user while transitioning from a standing position to a crouched position, and vice-versa. In a further aspect, each passive lower body support assembly includes an auxiliary body support structure to enhance the support of the human user in a crouched position. In another further aspect, each auxiliary body support structure is deployed in coordination with the movement of the seat support structure that supports the human user. In some embodiments, one or more body support structures are constructed from an elastic material that conforms to the ground surface when loaded by the weight of the human user.

An apparatus that includes a composite fuselage and motion control system designed to protect the human leg from knee pain and muscular fatigue created by repetitive vertical movement or extended periods of squatting. Fuselage panels and frame encapsulate the leg and functionally integrate with hard shell boots to create a rigid exoskeleton structure that resists radial displacement of the knee or ankle. The fuselage open clamshell leg harness utilizes wide composite body panels that disperse pressure across a large surface area, allowing the harness to provide body mass support and device securement without restriction of the body's circulatory system.

A wearable intelligent exoskeleton seat apparatus includes a thigh mechanism, a knee joint mechanism and a shank mechanism, the knee joint mechanism is fixedly coupled to the shank mechanism and the thigh mechanism respectively; the knee joint mechanism includes a knee joint support rod, a motor frame, a motor, a movable base, a flexible spring piece, ratchet teeth, a ratchet tooth shaft, a ratchet wheel, a ratchet wheel shaft and a shank connecting base; the knee joint support rod is fixedly connected with the thigh mechanism; the motor is mounted on the upper end of the knee joint support rod through the motor frame; the ratchet teeth is rotatably mounted to the knee joint support rod via the ratchet tooth shaft; the ratchet wheel is rotabaly mounted to the knee joint support rod via the ratchet wheel shaft; the ratchet teeth and the ratchet wheel are mounted directly opposite to each other.
