When the sciatic nerve is damaged, the lumbar disc is prolapsed, the sciatic neuritis, and the sacral nerve are paralyzed, the tendon reflex is weakened or disappeared. The patient was placed supine, the hips and knees were slightly flexed, and the lower extremities were taken out of the external rotation. The examiner used the left hand to gently support the patient's sole, so that the foot was overstretched, and the right hand was used to slap the Achilles tendon.

The examiner used the left hand to gently support the patient's sole, so that the foot was overstretched, and the right hand was used to slap the Achilles tendon. The normal reaction is contraction of the gastrocnemius muscle and flexion of the foot to the face. If the lying position cannot be measured, the patient can be squatted on the chair, the feet are suspended by the side of the chair, and then the Achilles tendon is smashed and the reaction is the same as before.
