Cyriax Release Test | Rationale & Interpretation

The video tutorial explains the Cyriax release test, a diagnostic tool for thoracic outlet syndrome. It covers patient positioning, test execution, and interpretation of results. The test involves positioning the patient with elbows at 90 degrees and forearms in a neutral position, then leaning the trunk back and elevating the shoulder girdles. A positive test is indicated by upper extremity symptoms. The video also discusses the test's specificity, with a 97% chance of thoracic outlet syndrome if symptoms appear in under a minute, and 88% if between one and three minutes.
