|Special instructions and comments
- The brachioradialis tendon cannot be easily seen on some patients and may difficult to palpate, so knowledge of surface anatomy is important with this test.
- Novice clinicians tend to strike the distal forearm and/or actually strike distal to the wrist joint (i.e., the muscle does not cross the wrist joint).
- You should be able to palpate a response even if you cannot see it.
Alternative patient position
- The brachioradialis reflex can also be tested with the patient positioned in supine.
