Paper Abstract:
|
Electrical stimulation using surface electrodes is not applicable to the precise FES (Functional Electrical Stimulation) because of the problem such as not to stimulate the inner muscle. In this study a forearm FES system using surface electrodes has been developed. We enable selective stimulation for inner muscle by this system. Eight surface electrodes were attached around the forearm at regular intervals. Finger motion was evoked by the electrical current through one electrode to another electrode. The combination of two different electrical current in the selection of pair electrodes allowed selective inner muscle stimulation. This new system was evaluated by the finger motion when inner muscle was given the selective electrical stimulation. One healthy subject participated in this evaluation experiment. As the results, finger motions were divided into six kinds of actions; the thumbs flexion, its extension, its radial abduction, flexion of the fingers except thumb, their extension and ulnar deviation of the hand. Furthermore, muscle position mapping was estimated by confirming the relationship between the electrode combination and observed actions of a hand and fingers. These results suggest that the proposed system enables FES using surface electrodes to stimulate the inner muscle selectively. |
