The hammer taps the Achilles tendon while the foot is dorsiflexed, and the foot, in response, should jerk toward the plantar surface
The Achilles reflex
Normal response must be a sudden leg extension
The patellar reflex
Occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot. The other toes fan out.
Normal in infants, abnormal in adults
