Roos Test (Elevated Arm Stress Test) | Rationale & Interpretation

The video tutorial explains the Roos test, also known as the elevated arm stress test, used to assess thoracic outlet syndrome. It provides step-by-step instructions on performing the test, which involves the patient raising their arms and opening and closing their hands for three minutes. The video discusses how to interpret positive test results, which may include symptoms like pain, numbness, or weakness. It also covers different types of thoracic outlet syndrome—neurological, arterial, and venous—and their specific indicators. The psychometric properties of the test are discussed, highlighting its high sensitivity but low specificity, making it useful for ruling out but not confirming the syndrome.
