| Adson Test | The arm being tested is held in a dependent position while the head is rotated from side to side. The test is positive for thoracic outlet syndrome if there is an obliteration of the radial pulse. |
| Allen's Test | While the patient raises one arm and makes a fist the examiner compresses the radial and ulnar arteries. Once the arm is lowered and the hand opened, the examiner releases one of the arteries then repeated releasing the other artery. If there is no flushing of the hand upon release of one of the arteries, the test is positive indicating a vascular occlusion of the released artery. |
| Compression Test | The examiner places their hands on the top of the patient's head and presses down causing a narrowing of the neural foramen. The test is positive if increased pain is noted and indicates nerve root irritation. |
| Spurling Test | Patient is asked to look up, turn the neck to one side while gentle downward pressure is applied to the head. The test is positive indicating a pinched cervical nerve when the patient reports pain and tingling. |
