A method of operating an exoskeleton device includes: receiving sensor information; connecting a clutch system to a pulley system in; determining whether to engage a drive train gear to the clutch system based on the sensor information; engaging the drive train gear through the clutch system when determined to engage the drive train gear; and powering a first motor to drive the drive train gear for controlling a joint or segment of exoskeleton device.

Systems and methods for exerting forces on a body, including a support structure defining a space and a plurality of surface contacting units that are configured to exert force upon the body, such that the weight is distributed away from the primary weight bearing regions to non-weight bearing regions of the body, or vice versa, without exerting significant shear or frictional forces on surfaces of the body. The systems and methods may be used to exert forces to cause fluid shift in different compartments of the body. Applications include treatment of various disease conditions including pressure ulcers, heart failure, high blood pressure, preeclampsia, osteoporosis, injuries of spine and to slow microgravity-induced bone and muscle loss. The systems and methods may be used to simulate gravity, weightlessness or buoyancy, in rehabilitation medicine. The system may include a chair, bed, a wearable suit or an exoskeleton.

A robot system for active and passive upper limb rehabilitation training based on a force feedback technology includes a robot body and an active and passive training host computer system. Active and passive rehabilitation training may be performed at degrees of freedom such as adduction/abduction and flexion/extension of left and right shoulder joints, and flexion/extension of left and right elbow joints according to a condition of a patient. In a passive rehabilitation training mode, the robot body drives the upper limb of the patient to move according to a track specified by the host computer, to gradually restore a basic motion function of the upper limb. In an active rehabilitation training mode, the patient holds the tail ends of the robot body with both hands to interact with a rehabilitation training scene, and can feel real and accurate force feedback.

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.

A dynamic exercise device having a base, a handle rotatably mounted in the base, and a stand which supports the base, the base being mounted in the stand via a sliding joint. In a first mode of use, the stand is detached and the base is placed against a surface on which the exercise device is used, and in a second mode of use, the stand is attached to the base such that in the second mode of use the stand is placed against the surface on which the exercise device is used.

A body weight support system includes a tether configured to be coupled to an attachment device worn by a user to couple the user to the body weight support system. A method of providing gait training includes defining a reference length of the tether when the attachment device is in an initial position and defining a threshold length of the tether. A first amount of body weight support is provided during the gait training as the user moves relative to a surface and the length of the tether is less than the threshold length. A second amount of body weight support is provided during the gait training as the user moves relative to the surface and the length of the tether is greater than the threshold length. The method further includes displaying data associated with the gait training on a display of an electronic device.

A exercise device includes: a u-shaped frame; first and second arms pivotally coupled to ends of the frame; a first pair of bands that resist pivotal movement between the u-shaped frame and each of the first and second arms; and an arm bar. The arm bar is releasably coupled proximate to the free end of each of the first and second arms. As configured the device is usable for a first set of exercises. A first end of each of a second pair of resistance bands is respectively secured in proximity to first and second ends of the arm bar. The second ends of the second pair of resistance bands have loops fixedly secured thereto. When the arm bar is not releasably secured to the first and second arms, it is usable in combination with those bands and loops for a second set of exercises, providing a full body workout.

Assisted unracking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining a readiness of the user to accept resistance based at least in part on the detected state of the cable. It further includes selectively applying resistance by the motor to the cable according to the determined readiness of the user to accept the resistance.

A physical exercise assembly includes a table that is substantially elongated to accommodate a user lying on the table. A cable support is spaced below the table and a bracket is coupled to the cable support. A plurality of pulleys is rotatably coupled to the cable support. A pair of first bands is coupled to the bracket and extends around respective ones of the pulleys. A pair of handles is each coupled to a respective one of the first bands for gripping and exercising arms. A pair of second bands is each coupled to the bracket and extends around respective ones of the pulleys. A pair of ankle straps is each coupled to a respective one of the second bands for exercising legs.

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.
