The focus of this study was to introduce the use of localized joint torque as a new approach to analyzing finger dynamics. By using a method of continuous acquisition of all the joints in the finger simultaneously and a rigid body model, the principles of inverse dynamics may be applied to calculate the required joint torque for motion. Though this study presents only torque differences, it paves the way for future computations of joint efficiency. Previous investigators have used the Profundus tendon force and excursion to calculate the work of the system (Greenward, 1994). Using the derived equations of motion and kinematic data, the localized work at the joints may be calculated along with accurate measures of bowstringing effects.
