The peroneal nerve controls the muscles that lift your foot. This nerve runs near the surface of your skin on the side of your knee closest to your hand. Activities that compress this nerve can increase your risk of foot drop. Crossing your legs. People who habitually cross their legs can compress the peroneal nerve on their uppermost leg.
Surgeons at the Center for Nerve Injury and Paralysis can treat foot drop: paralysis of the muscles below the knee that lift the front part of the foot, resulting in a foot that hangs at the ankle. A person who has foot drop may have difficulty walking and need to wear a brace on the leg. Possible causes of foot drop include lumbar disc herniation (damage to a nerve root in the lumbar spine), damage to the peroneal nerve (usually near the knee) or damage to the nerve bundles in the lumbosacral plexus.
