Electrode placement. Example of placement of electrode on (top) AbPL and placement of anode at the dorsum of the wrist and (bottom) above FPB muscle and OpP muscle. The AbPL electrodes was placed just medial of the radial bone, approximately 5 cm proximal to the wrist joint, the OpP electrode was placed laterally on the thenar, about 1/3 of the length of the first metacarpal bone, measured from the proximal side. The FPB electrode was placed at about half the length of the first metacarpal bone on the medial side of the thenar. Exact electrode locations were determined experimentally based on observed responses and subject comfort.
