Adson's test

 [ad´sunz]
a test for thoracic outlet syndrome; with the patient in a sitting position, the hands resting on the thighs, the examiner palpates both radial pulses as the patient rapidly fills the lungs by deep inhalation and, holding the breath, hyperextends the neck and turns the head toward the affected side. If the radial pulse on that side is decidedly or completely obliterated, the result is positive.
