Preliminary Investigation Of Residual Limb Plantarflexion And Dorsiflexion Muscle Activity During Treadmill Walking For Trans-Tibial Amputees, M. Barbara Silver-Thorn, Thomas Current, Benjamin Kuhse

Biomedical Engineering Faculty Research and Publications

Background: Novel powered prosthetic ankles currently incorporate finite state control, using kinematic and kinetic sensors to differentiate stance and swing phases/sub-phases and control joint impedance and position or torque. For more intuitive control, myoelectric control of the ankle using the remnant residual limb dorsiflexors and plantarflexors, perhaps in concert with kinetic and kinematic sensors, may be possible.

Objective: The specific research objective was to assess the feasibility of using myoelectric control of future active or powered prosthetic ankle joints for trans-tibial amputees.

Study Design: The project involved human subject trials to determine whether current techniques of myoelectric control of upper …
