Biomechanical effects of Agilik powered knee-ankle-foot-orthosis


This study aims to measure the best ankle-foot-orthoses to be used with the Bionic Power Agilik knee exoskeleton to maximize benefits of the device to the wearer. This study will evaluate 3-5 different AFOs during walking in a lab that allows us to measure joint angles and forces while you walk. This research will help us determine the most effective use cases for the Agilik exoskeleton.
