A Myoelectrically Controlled Wrist-Hand Orthosis for Brachial Plexus Injury

Abstract

A myoelectrically controlled powered wrist-hand orthosis was developed for an individual with a unilateral brachial plexus injury. The lightweight orthosis, which incorporated supracondylar suspension, provided up to 14 lbs. of pinch force and had a closure time of one second. The device also offered the individual added independence during selected two-handed activities.
