Abstract: A mechanical support device comprising a variable impedance module is disclosed herein. The variable impedance module is configured to adjustably control a stiffness, a damping, and/or a range of motion of a joint. In various instances, the mechanical support device is intended for use with an ankle joint. In such instances, the mechanical support device further comprises a shoe and an ankle brace releasably coupled to the shoe.

Abstract: An illustrative prosthesis and orthosis testing system includes a platform that receives a prosthesis or orthosis. A motor or a weight are configured to apply a load to the prosthesis or orthosis, and one or more load cells are configured to measure a magnitude of the load on the prosthesis or orthosis. The system also includes one or more encoders configured to measure one or more positions and one or more orientations of the prosthesis or orthosis in response to the applied load.

Abstract: An exoskeleton device is disclosed. The exoskeleton device comprises a Bowden cable, a shank portion comprising a strut, and a foot portion coupled to the shank portion by a rotational joint. The foot portion comprises a heel lever and a pulley attached to the heel lever, wherein the strut of the shank portion is configured to redirect the Bowden cable toward the pulley, wherein the pulley is configured to redirect the Bowden cable back toward the shank portion, and wherein the Bowden cable is configured to generate torque by pulling the pulley. The exoskeleton device further comprises a midsole, wherein the midsole is releasably coupled to the lever, and wherein the midsole is configured to transmit force to a foot of a user.
