Execution:
- The patient is in standing position
- The patient is asked to slowly abduct the arms maximally
Positive Outcome: Provocation of the patient’s familiar pain during 45-60° and 120° for subacromial pain syndrome, as well as between 170-180° indicative of a symptomatic AC joint

| Comment: The Painful Arc Syndrome only minimally alters the the post-test probability of subacromial pain syndrome and is not a good stand-alone test | |||||
