Test to be performed - Brachioradialis reflex examination with the patient positioned in sitting

Expected findings - Palpable and visible contraction of the brachioradialis muscle with slight elbow flexion, as well as equivalent brachioradialis muscle reactivity when compared to the contralateral extremity

Equipment - Non-latex Taylor (i.e., tomahawk style hammer) or neurological reflex hammer

Testing procedures
  1. The forearm and elbow region should be visible and the proximal arm must be free of restrictive clothing (i.e., a tightly rolled up shirt sleeve).
  2. Stand in front and to the side of the extremity to be examined.
  3. With the patient seated, allow the patient's arm to rest in his or her lap.
  4. Localize the brachioradialis tendon.
  5. The brachioradialis muscle is typically relaxed, but reinforcement procedures can be used if needed.
  6. Allow the reflex hammer to swing loosely between your thumb and forefinger through a 45 to 60 degree arc.
  7. Strike the radial side of the forearm about 8 to 10 cm above the wrist with the base or apex of the reflex hammer running perpendicular to the muscle fibers.
  8. Standardize the size of the reflex hammer and force if needed.
  9. Palpate and visually observe the response to the provided stimulus (i.e., slight elbow flexion).
  10. Repeat the procedure.
  11. Document your findings.
