Shoulder ABDuction Test | Rationale & Interpretation

The video tutorial explains the shoulder abduction test, used to assess cervical radiculopathy and thoracic outlet syndrome. It describes the test setup, where the patient positions their arm to rest their hand on their head. The video details two types of positive test results: the Bacoti sign, indicating symptom relief and suggesting cervical radiculopathy, and increased symptoms, suggesting thoracic outlet syndrome. The psychometrics of the Bacoti sign are discussed, highlighting its high specificity but low sensitivity.
