Shoulder Assessment Series Part 21: Scapular Assistance Test (SAT) The Scapular Assistance Test assesses for scapular dyskinesis, which is often the case with shoulder patients or sometimes the underlying reason for shoulder problems in the first place. If this test is positive, you can assume that your patient is lacking lateral rotation of the scapula, which is necessary for the humerus to abduct (and flex) without impinging. | Physiotutors
