Abstract:
Restoring walking functions will greatly improve the foot-drop patients' life quality. In this work, we sampled 10 healthy subjects' gait data when walking in 4 different stride frequency overground and developed a dynamic Functional Electrical Stimulation (dFES) system for foot-drop patients' walk training, using the processed tibialis anterior (TA) muscle EMG signal. The data sampled under the new strategy can be used by FES system directly. And the dFES system can provide dynamic Pulse Width Modulation (PWM) FES serial according to the healthy subjects' TA EMG intensity features.
