This patient was suffering with left buttock and leg pain. Her MRI showed a large paracentral disc and severe spinal stenosis. There was no weakness but the left medial hamstring reflex was absent. The absent left peroneal reflex provided further confirmation of an L5 radiculopathy.
Other occasionally useful reflexes (1):
Orbicularis oculi Jaw Clavicle Pectoralis Deltoid Pronator Finger flexor Deep abdominal Suprapatellar Hamstring Adductor Extensor digitorum brevis Tibialis posterior Plantar stretch
