Shoulder-related pain in the general adult population has been estimated to be between 6.9 and 26% (potentially 1 in 4 people will experience shoulder dysfunction in their lifetime). Thirty age and gender matched subjects were tested using a specially designed device to measure torque during internal/external shoulder rotation. Subjects with shoulder pain had a decreased shoulder range of motion and increased torque at full internal and external rotation. This device was able to objectively distinguish the amount of stiffness between two populations of subjects.
