Which assessment tool is best for evaluating potential thoracic outlet syndrome?

• A. Valgus stress test
• B. Adson's test
• C. Neer test
• D. Phalen's test

Answer: (B)

Adson's test is specifically designed to assess for thoracic outlet syndrome (TOS), which involves compression of the neurovascular structures in the thoracic outlet area. This test evaluates the presence of vascular changes in response to specific arm positions and head movements. By having the patient extend their neck and take a deep breath while turning the head toward the affected side, any reduction in the radial pulse or reproduction of symptoms can indicate TOS. The other assessment tools listed serve different purposes. The valgus stress test is used for assessing the integrity of the medial collateral ligament of the elbow, the Neer test evaluates for impingement of the shoulder, and the Phalen's test is primarily used to diagnose carpal tunnel syndrome by eliciting symptoms related to median nerve compression in the wrist. None of these tests address the specific structures and mechanisms involved in thoracic outlet syndrome, making Adson's test the most appropriate choice for evaluating this condition.
