II. Technique
- Perform Brachioradialis Reflex
- Strike reflex hammer at distal radius overlying radial styloid process region
- Observe for flexion at elbow (normal) and fingers (abnormal)
III. Findings
- Normal
- Normal Brachioradialis Reflex results in brachioradialis contraction and elbow flexion
- Abnormal
- No brachioradialis contraction or elbow flexion
- Wrist and finger flexion only
IV. Causes: Abnormal Reflex
- Typically due to C5-C6 spinal cord lesion
- Associated with an absent Biceps Reflex and hyperreflexia at the triceps
