Abstract: A method and apparatus for enhancing the operation of leg prothesis is provided. The apparatus includes a cable configured to be attached to the leg prosthesis worn by a subject to move through a plurality of gait phases. The apparatus also includes a module configured to be mounted to the leg prosthesis. The module includes a tension spring configured to engage the cable to maintain tension in the cable. The module also includes a locking mechanism configured to lock a position of the tension spring and maintain a length of the cable defined between the module and the leg prosthesis during a first gait phase of the plurality of gait phases. The locking mechanism is further configured to unlock the position of the tension spring to permit variation of the length of the cable during a second gait phase of the plurality of gait phases.

Abstract: Described herein relates to a variable resistance exercise system and method of providing resistance to a target muscle group at a predetermined joint of a user. The variable resistance exercise system may be configured to provide speed-dependent, bi-directional, and/or variable resistance at the predetermined joint. Accordingly, the variable resistance exercise system, may target the predetermined joint (e.g., an elbow) and/or provide resistance against the ability of the user to flex the targeted muscle group about the predetermined joint, optimizing the effectiveness and safety of resistance training, allowing the promotion of muscle hypertrophy of the user.

Abstract: Described herein relates to an apparatus and method of capturing a movement of a targeted muscle group of a user and transferring it to another muscle group of the user. The appendage work sharing device comprises a cable pulley system, creating an external mechanical pathway to transfer upper limb joint motion or force to the lower limb joints. Accordingly, by creating the external mechanical pathway, the appendage work sharing apparatus provides a self-regulated and self-powered means to assist lower limbs during ambulatory movements using upper limb muscles, reducing the lower limb muscle work (e.g., electromyography) during several ambulatory movements (e.g., sit to stand and step up) using upper limb muscles (e.g., shoulders, biceps, or triceps).
