During the physical examination,the patient reports pain and demonstrates 85 degrees of right shoulder abduction active range of motion compared to 170 degrees in the left shoulder.During passive range of motion testing,the therapist notes 170 degrees of pain-free right shoulder abduction.What tissue in the right shoulder is MOST likely responsible for the limitation in active range of motion?

Question

The discrepancy between active and passive range of motion, where active motion is limited and painful but passive motion is not, suggests a problem with the muscles or tendons responsible for that movement. The supraspinatus tendon is a key component of the rotator cuff that assists with shoulder abduction. If there's pain and limitation only during active movement, it indicates that the issue is likely with the muscle or tendon (in this case, the supraspinatus tendon) rather than the joint capsule, another tendon not primarily responsible for abduction, or a bone deformity.
