Study Location
University of Michigan – Ann Arbor, MI
Research Objectives
Powered leg prostheses can greatly assist individuals with above-knee amputations, but these devices are currently designed for a limited set of activities. This study aims to validate a new way to control powered prosthetic devices to restore walking ability in many different activities.
The study protocol will require participants to walk with their existing prosthesis and with an experimental powered prosthesis during sit-to-stand, level-ground walking, stair ascent/decent, and stepping over obstacles. This video demonstrates these activities: https://youtu.be/sBC12VDbaes
