Abstract

A system for isolating, evaluating and exercising the muscle groups of the human hand, wrist, arm and shoulder including an adaptable detector for interpreting the cardinal movements of at least one muscle group of the hand during flexion, extension, or deviation of the wrist, or abduction, opposition, flexion or hyperextension of individual digits of the hand. The detector translates the movements of the muscle group into rotational data for the system and effectively isolates the movements of the muscle group so that the movements of other muscle groups of the body are not detected by the system. The system also includes a controlled resistance coupled to the detector which provides a variable resistance against the muscle group and ascertains the force applied to the detector by the movements of the one muscle group. The resistance can be varied to provide isotonic, isokinetic, or isometric modes of testing against said at least one muscle group.
