Stimulating Electrodes
The Orthosis transmits electrical stimulation through five surface electrodes custom placed
by the clinician to provide optimal wrist and hand movements. See Table 4-1.
• Two electrodes are placed on the ventral aspect of the forearm, to stimulate the flexor
muscles.
• One electrode is placed on the thenar eminence to stimulate the thenar muscle group.
• Two electrodes are placed on the dorsal aspect of the forearm, to stimulate the extensor
muscles.
