Provoke and reproduce symptoms by stressing the thoracic outlet to identify vascular or neural compression. Adson's test specifically targets the interscalene triangle where the subclavian artery and brachial plexus can be compressed between the scalene muscles and the first rib. In this maneuver, the patient extends the neck and turns the head toward the affected side while taking a deep breath, and the clinician palpates the radial pulse. A noticeable decrease or disappearance of the pulse during the maneuver suggests compression at that space, consistent with thoracic outlet syndrome due to scalene muscle involvement. This makes it a classic test for detecting TOS in exams.

Other tests listed are used to probe other potential compression sites within the thoracic outlet, such as the pectoralis minor or costoclavicular space, but Adson's test is the one most directly associated with compression of the interscalene area, which is a common focus in thoracic outlet evaluations.
