Grasp force results for all 3 subjects. Grasp force obtained before surgery is due to passive tenodesis function (no active thumb flexion). Changes in grasp force after surgery with the NP turned off are due to augmentative surgical procedures, such as tendon transfers, and changes in passive properties of the hand. The increased grasp force with the NP on is due to the force provided by AdP and FPL stimulation. AdP, adduct or pollicis.
