FESの電気刺激波形が示指MP関節動作へ及ぼす影響に関する研究

抄録

Recently, many types of Functional Electrical Stimulation (FES) devices have been developed for rehabilitation and neural prosthesis. The effect on human motion by changing the waveform pattern of electrical stimulation was evaluated for suitable parameters for the precise control of MP joint of index finger, In this study, we use a combination of square wave waveforms and then we focused on the stimulation period, stimulation amplitude, and pulse width. The results showed that the stimulus amplitude and pulse width had a strong linear correlation with MP joint angle increase. However, the stimulation period may have nonlinearity. These results suggest that the voltage and pulse width are possible parameters for the precious human hand motion control with FES.
