Full Can Test – Supraspinatus pathology- The patient can be seated or standing for this test, holding their arm in 90° of elevation in scapular plane (30° anterior to the frontal plane) with full external rotation of the glenohumeral joint. In this position, the patient’s thumb should be pointing up. The therapist should stabilize the shoulder while applying a downward force to the arm whilst the patient tries to resist this motion. This test is considered positive if the patient experiences pain or weakness with resistance to the shoulder complex.
