During the chest test, the patient stood, the examiner held the elbow of the patient in one hand, and the radial artery was cut in one hand, and the patient was chested and the arms were extended straight to the elbow. After checking one side, check the opposite side and compare it to the left and right. If the brachial artery pulsation weakens or disappears during the activity, the pain and numbness in the arm and hand are positive, suggesting that the subclavian artery and brachial plexus are compressed in the first rib and the clavicle space. It is clinically seen in the thoracic outlet syndrome.
