Torque production in the shoulder of the normal young adult male

Abstract

Shoulder torque measurements were obtained from 36 normal young adult males during flexion, abduction, internal rotation, and external rotation. Normative, an gle-specific torque measurements were determined un der isometric conditions and isokinetically at 48 deg/ sec. The effects of dominance, angular velocity, and joint position were determined and a method provided for determining the expected maximal torque at a spe cific speed and position based upon torque measure ments from the contralateral shoulder. This method can be used in cases of unilateral shoulder abnormalities to predict normative torque values for the affected side based on torque measurements from the unaffected shoulder.
