Powered Knee & Ankle Prosthesis

Individuals with transfemoral amputation are subject to higher levels of exertion when using energetically passive prostheses. Powered prostheses have been proven to reduce this increased metabolic expenditure as well as provide additional benefits of reducing increased loading seen on the intact limb post-amputation. The EPIC lab has developed a powered prosthesis that utilizes two motors to provide assistance independently at both the knee and ankle joints. There a variety of embedded sensors such as encoders, inertial measurement units (IMUs), and a 6-DOF loadcell to help extract user information as one ambulates across a variety of walking modes (i.e. overground, ramps, and stairs). We are interested in developing intelligent intent recognition systems using machine learning and sensor fusion techniques that restores and improves overall independence and mobility.
