Authoring team

An inverted brachioradialis reflex:

  • is said to be present when the supinator reflex elicits finger flexion and not elbow flexion
  • is associated with an absent biceps jerk and an exaggerated triceps jerk
  • is indicative of a spinal cord lesion at C5 or C6, e.g. due to trauma, syringomyelia, or disc prolapse
  • occurs because a lower motor neurone lesion of C5 is combined with an upper motor neurone lesion affecting reflexes below C5
