Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the lower back and runs down the back of each leg. This nerve controls the muscles of the back of the knee and lower leg. It also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot.
Sciatic nerve damage. The sciatic nerve is located in the back of the leg. It supplies the muscles of the back of the knee and lower leg. The sciatic nerve also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot. Partial damage to the nerve may demonstrate weakness of knee flexion (bending), weakness of foot movements, difficulty bending the foot inward (inversion), or bending the foot down (plantar flexion). A person's reflexes may be abnormal, with weak or absent ankle-jerk reflex.
