The Scarf Test is for the AC Joint.

The shoulder has a wide range of movement.The rotator cuff muscles and surrounding soft tissues provide the stability of the shoulder joint, which is unusual in that the glenoid is very shallow.

All exams should have a systematic approach.The Look, feel move approach is used the most.

Once you have the patient's consent, wash your hands and ask them to expose their shoulders and clavicles bilaterally.

There are tests for shoulder impingement, which is inflammation of the rotator cuff's supraspinatus tendon.Ask the patient if they want to use their arm.The forearm should be parallel to the floor if you flex the elbow to 90'.Try to forcibly rotate the shoulder joint by pressing down on the patient's wrist.The patient should be relaxed because this is a passive movement.The shoulder cuff is pressed against the coraco-humeral ligament.The test can be repeated with external rotation to check the subscapularis.

When there is a strong degree of clinical suspicion, the test may help to confirm the diagnosis.
