Abstract

An improved shoulder strength adduction device is provided for use in determining the strength of a person's shoulder musculature. The device comprises a pair of hand grips connected by pivotal scissors frames to a support bar and a load bar, with a force gauge unit being mounted between the support and load bars. Exertion of manual adduction force to move the hand grips toward each other is effective to urge the support and load bars toward each other, whereby the adduction force can be detected and displayed by the force gauge unit to provide a direct reading of shoulder or upper body strength. The device includes a variety of mechanical improvements designed to enhance ease of use while achieving increased force indicating accuracy.
