Characterizing Ankle Function During Sloped Locomotion for Prosthesis Development

The proposed study aims to characterize biological ankle joint function during walking and running on slopes in order to further develop advanced powered ankle-foot prostheses. Ankle joint torque and angle data will be collected from non-amputees while walking and running at multiple speeds and slopes. This data will be used to develop control parameters for a powered ankle-foot prosthesis. Then, these parameters will be implemented and tested in a powered prosthesis worn by people with below the knee amputations.
