Abstract: A portable system for dynamometry, exercise, and rehabilitation comprises a base, a detachable servomotor assembly, an embedded control system, and a physical human-machine interface for securing a human limb into a stabilized position for use in a repeatable and ambidextrous manner. In another embodiment, the portable system includes a power source and a user interface subsystem for selecting operative modes and input parameters and for real-time processing, display, and storage of the values collected by the system during operation. In another embodiment, a method for determining strength of an isolated muscle group of a human joint is disclosed. The method includes the steps of mounting and securing a detachable servomotor assembly of a portable dynamometer upon a surface and securing the human joint to be tested into a stable position with an adjustable, ambidextrous distal limb attachment assembly for use of the portable dynamometer in a readily repeatable manner.

Abstract: An exerciser having two linkages each with a member and a projecting extension. A distal end of each of the extensions travels in an oblong orbital path while one end of the member travels in a circular, orbital path and the other end travels in a reciprocating manner back and forth. This other end has wheels arranged to roll along a track without sliding. The exerciser has foot supports each attached to an associated one of the distal ends of the extensions and has arms that move in a reciprocating manner opposite each other. Provision is made to ensure that the arms and foot supports move through dead spots at the ends of their respective courses of travel. The arms and legs traverse respective distances when moving back and forth that are substantially the same in dimension.

Abstract: A transportable offloading weight apparatus for supporting a portion of a patient's weight undergoing gait training is provided. The offloading weight apparatus employs a resilient suspension system to reduce the amount of weight borne by a patient. The offloading weight apparatus includes a frame having a connection linkage, a rope routed in the frame through a pulley system, a resilient cord that is attached to the frame at one end and connected to the connection linkage through one end of the rope, a harness support assembly secured to another end of the rope and a tension adjustor for applying tension to the resilient cord.
