Abstract
It has been shown previously that for slow to normal walking speeds the ankle joint behaves similar to a passive mechanism from foot flat to push off. Thus a passive ankle mechanism was developed in order to mimic able-bodied gait in amputees. The ankle device is shown to be capable of matching the ground slope during heel strike, efficiently storing breaking energy from the user during rollover then releasing that energy to assist in push off, and raising the toe during swing phase to reset the system for the next heel strike. Mechanism functionality was verified through lab testing. Human testing was done through an ankle-bypass system on able-bodied subjects to verify device safety and functionality.
