Abstract
Apparatus and methods are provided for determining a locomotion mode that can be provided to a controller of a lower prosthesis limb in order to accurately control the prosthesis. One or more prosthesis sensors are provided that break a gait cycle down into a plurality of gait phases. EMG sensors provide signals to a processor that directs them to a gait phase specific classifier that is used to determine a particular locomotion mode for the wearer. With the locomotion mode accurately known, the prosthetic device can be accurately controlled.
