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

THE SCAPULA ASSISTANCE TEST (SAT) The SAT is rather a symptom alteration test that is often used in routine care to guide further treatment. If symptom alteration can be achieved by the SAT, one might assume that scapular strengthening can have a positive impact on the patients shoulder symptoms. According to Rabin et al. (2006) the SAT has a moderate reliability with a Kappa value of k= 0.53 in the scapular plane and a substantial reliability with Kappa of k= 0.62 in the sagittal plane. | Physi
