Execution:
- Have the patient in supine lying position
- Depress the patient’s shoulder with your hip, abduct it to 10°, and flex the elbow to 90°
- Flex the wrist and fingers(including the thumb) and pronate the forearm
- Slowly extend the elbow until the patient complains of familiar symptoms
- 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 are reproduced. Some authors score the test negative in case of a marked decrease of mobility (>10°)
