A knee rehabilitative device permits a user to provide resistive stretching caused when the leg or other joint is extended or straightened, facilitating exercise and strengthening of the user's muscles and improved flexibility in the area of the knee or other joint area.

A portable and kinetic motion resistance upper body invention that can be used for a variety of exercises. This invention combines dial tension adjustment clutch sheaves, a variable linear tract bearing and a one piece resistance shock-cord, together these core components achieve a unique minimal impact work-out. The multi-motion and changeable adjustments for this invention, result in a wide variety of muscular stimulation and therapeutic exercises that are non-existent in the fitness and health industry. The outcome of the mechanism can be customized for a particular sport requirement or physio and other therapeutic restorations, or even for case specific industrial and robotic counter-balancing controls. This invention is can also be used as a lift-assist device.

A wearable apparatus for the treatment or prevention of osteopenia or osteoporosis, stimulating bone growth, preserving or improving bone mineral density, and inhibiting adipogenesis is disclosed where the apparatus may generally comprise one or more vibrating elements configured for imparting repeated mechanical loads to the hip, femur, and/or spine of an individual at a frequency and acceleration sufficient for therapeutic effect. These vibrating elements may be secured to the upper body of an individual via one or more respective securing mechanisms, where the securing mechanisms are configured to position the one or more vibrating elements in a direction lateral to the individual, and the position, tension, and efficacy of these vibrating elements may be monitored and/or regulated by one or more accelerometers.

In various embodiments, provided herein are systems, methods, processes, and devices for providing locomotive rehabilitation to a subject via one or more gait motions that substantially accurately mimic motions performed in healthy, natural gait cycles. The system may mimic natural gait motions via footplates and handles, and one or more linkage systems. In particular embodiments, the system may further include a motor unit and/or clutch for providing controlled forces assisting or resisting motions of a linkage system. Further, the system may include a tower for operating in a standing or seated position. In at least one embodiment, the system includes a body weight support system that provides offloading forces to a subject.

A mouse-type rehabilitation exercise device includes a mouse body on which a hand is mounted, a wheel moving the mouse body, a first motor aligning a position of the wheel such that the mouse body moves to a desired direction, a second motor rotating the wheel such that the wheel aligned by the first motor moves to a desired position, a clutch disposed between the second motor and the wheel to enable and disable a power transmitting to the wheel from the second motor, and a controller controlling a driving of the first motor, the second motor, and the clutch.

System and method for providing both powered and free swing operation in a powered orthotic exoskeleton joint. The joint includes a processor controllable ratchet wheel and pawl type clutch, configured to engage or disengage upon receiving force from a servo actuator. When the processor determines that the clutch should be engages, it directs the powered actuator to couple the pawls to the ratchet wheel, allowing torque to be transferred from the joint's powered motor, through the clutch, to the gearing that subsequently controls the motion of the joint. Conversely, the processor can direct the powered actuator to decouple the pawls from the ratchet wheel. This in turn decouples the ratchet wheel from the motor, thus allowing the remainder of the joint and any associated joint gearing to engage in relatively free swing motion, without any interference from the motor.

A chair includes a seat (2) and also includes a pair of thigh support elements (17) pivotal n a generally downwardly direction about front pivot axes (20) from a first state forming with a central seat element (15) a substantially common plane, to a second downwardly extending state. The elements (17) are also pivotal about second pivot axes in a generally rearwardly direction for urging the user's thighs away from each other for stretching the adductor muscles. Foot support members (49) extend transversely and sidewardly on respective opposite sides of the chair (1) from a support element (46) for supporting the foot during a stretching exercise with the corresponding thigh of the subject extending downwardly from the seat (14) and the lower leg extending from the knee in a upwardly inclined direction to the foot support member (49) for stretching the quadriceps and the hip flexor muscles of the subject.
