In the STAR Shoulder classification, Subacromial Pain Syndrome is associated with which deficits?

• A. Shoulder pain and muscle performance deficits
• B. Shoulder pain and mobility deficits
• C. Shoulder pain and motor control deficits
• D. Shoulder pain and instability deficits

Answer: (A)

Subacromial Pain Syndrome in the STAR Shoulder framework is characterized by deficits in muscle performance—the strength, power, and endurance of the rotator cuff and scapular stabilizers. The pain you feel during overhead activities often stems from a failure of these muscles to adequately control the humeral head and scapula, leading to compression under the acromion and irritation of subacromial structures. Clinically, you’d expect weakness or reduced endurance on resisted tests of the shoulder and scapular muscles, sometimes with pain limiting performance. Mobility deficits would imply a primary limitation in range of motion, which SAPS does not define as the main problem here. Motor control deficits focus on coordination and movement quality, such as abnormal movement patterns, which may accompany SAPS but are not the defining impairment. Instability deficits involve laxity or true joint instability, which again is a different problem. The key feature for SAPS is weakness and endurance deficit in the shoulder girdle muscles in the setting of pain.
