The ankle jerk, also known as the Achilles reflex, is a deep tendon reflex that occurs when the Achilles tendon is tapped, usually at the back of the ankle. This action causes the calf muscles to contract and the foot to jerk downward. It is often tested during neurological examinations to assess the integrity of the S1 and S2 spinal nerves. A diminished or absent ankle jerk can indicate potential neurological or muscular issues.
