Development Of An FES System Controlled By EMG Signals

This paper describes about control strategy of an FES system controlled by EMG signals. Partially detected EMGs just before the stimulating pulses were used for eliminating the influence of the stimulus from the EMG during motion. Parameters for providing stable FES control w ere investigated in the forearm muscles of healthy subjects. The system operation for controlling hand movement was tested by using the EMGs from the wrist muscles as control signals in 3 healthy subjects and a C6/7 quadriplegic.
