Execution:
- Have the patient in supine lying position
- Depress the patient’s shoulder with your hand and bring it into 90° of abduction
- Extend the wrist and fingers(including the thumb), pronate the forearm, and bring the shoulder into lateral rotation
- Slowly bring the patient’s fingers and hand towards their ear (further abducting the shoulder)
- Confirm that the findings are due to nerve stretch by flexing the elbow a little to create slack and ask the patient to laterally flex their neck to the contralateral side, which should increase the symptoms again
Positive Outcome: The patient’s familiar arm symptoms like shooting pain or paresthesia is reproduced. Some author score the test negative in case of a marked decrease of mobility (>10°)
