Subscapularis Tears | Special Tests | Rationale & Interpretation

The video tutorial covers the anatomy and injury mechanisms of the subscapularis muscle, highlighting its robustness compared to other shoulder muscles. It explains two diagnostic tests for subscapularis tears: the belly press test and the Gerber liftoff test. Both tests have high specificity but low sensitivity, meaning a positive result strongly indicates a tear. The tutorial provides step-by-step instructions for performing each test and discusses common compensations and psychometric properties.
