Which test is used to assess for thoracic outlet syndrome?

Phalen's test
Adson's test
Finkelstein's test
Spurling's test

The correct answer is: Adson's test

Adson's test is specifically designed to assess for thoracic outlet syndrome, which involves the compression of nerves or blood vessels in the thoracic outlet area. This area is located between the collarbone and the first rib, where the brachial plexus and subclavian artery run. During Adson's test, the patient is asked to take a deep breath and turn their head toward the involved side while the practitioner palpates the radial pulse. A significant reduction or disappearance of the pulse indicates a positive test, suggesting potential thoracic outlet syndrome due to vascular or neural compression. In contrast, other tests mentioned serve different purposes: Phalen's test is primarily used to diagnose carpal tunnel syndrome by assessing median nerve compression in the wrist, Finkelstein's test evaluates for De Quervain's tenosynovitis in the wrist, and Spurling's test is utilized to determine cervical radiculopathy by reproducing nerve root irritation through cervical extension and lateral bending. Each of these tests targets specific conditions, highlighting the unique diagnostic role of Adson's test in identifying thoracic outlet syndrome.
