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 at least one 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 at least one second gait phase of the plurality of gait phases.
