Important Notes
The sciatic nerve (also called ischiadic nerve) is the largest nerve in the body and controls most lower leg function. Complete paralysis (80%) means the foot dangles and drops with no active movement possible below the knee. Incomplete paralysis (60%-10%) means varying degrees of motor weakness and sensory impairment. Often secondary to lumbar spine conditions (DC 5237, 5242, 5243). Bilateral factor applies when both legs are affected.
