Primary outcomePrimary: Sternal Displacement During Towel Folding Task — 1.0; 1.06; 0.88 meters
Summary
This study will compare the functional performance of voluntary opening (VO) and voluntary closing (VC) body powered prostheses. We hypothesize that the ability to sense cable tension and produce progressively higher pinch from shoulder force will result in advantages for the VC terminal device (TRS, Grip 3) in terms of proprioception and overall function. The specific aims of this clinical trial are to:
1. Determine if accommodation with a VC Grip 3 prehensor will result in reduced compensatory motion during activity.
2. Determine if accommodation with a VC Grip 3 prehensor will result in improved function in activities of daily living.
