Average moment arm versus joint angle curves are summarized for the nonimpaired, PRC, and SE4CF conditions. Moment arms of the primary wrist (ECRL, ECRB, ECU, FCU, FCR) and extrinsic thumb (EPL, EPB, APL, FPL) muscles were experimentally measured in cadaveric specimens using the tendon-excursion method.
