If the patient complains of pain at the painful arc of 170 degrees and above of shoulder elevation, then the acromioclavicular joint might be involved.
In the case of acromioclavicular joint pathology, the pain tends to be localized at the joint. If there is any impingement, then the pain will be diffused.
Pain is commonly felt during the movement between 45 - 120 degrees in subacromial bursa and supraspinatus insertion pathologies.
