In the Achilles reflex, the hammer taps the Achilles tendon while the foot is dorsiflexed, and the foot, in response, should jerk toward the plantar surface. General Inquiries. Examination of reflexes include Achilles tendon reflex. The S1 nerve root also supplies innervation for the ankle jerk (tap on the achilles tendon and the foot goes down), and a loss of this reflex indicates S1 impingement, although it does not create loss of function. The Achilles reflex checks if the S 1 and S 2 nerve roots are intact and could be indicative of sciatic nerve pathology. Depressed reflexes: Reflexes are diminished or lost in nerve root lesions, peripheral nerve lesions, metabolic diseases such as diabetes or hypothyroidism, and muscle disease. If requested before 2 p.m. you will receive a response today. Common causes So firstly, L 4, L 5 and S1 spinal roots’ contribution to sacral plexus was observed and the diameter of each root at the point of intervertebral foramen was measured, and the diameter of each branch contributing to sacral plexus was recorded as well.
