Abstract

A feedback controlled functional electrical stimulation (FES) system is developed to provide the hemiplegic patients a real-time stimulation to their muscles to prevent the drop-foot and the quadriceps weakness from happening during gait training. The FES is controlled by tilt sensors (t.s.) and triggered by footswitches (f) with real-time feedback. As the FES receives the signals from these sensors, it adjusts and outputs an optimum set of stimulation parameters automatically.
