The video tutorial explains the Gerber liftoff test, a special test used to identify tears in the subscapularis muscle. It highlights the test's high specificity (98%) but low sensitivity (35%), meaning a positive result strongly indicates a tear, but a negative result does not rule it out. The tutorial provides a step-by-step guide on performing the test, emphasizing the need for sufficient shoulder range of motion. If the range of motion is inadequate, the belly press test is suggested as an alternative. The video also discusses the importance of using multiple tests to confirm rotator cuff pathologies.
