Foot-drop
Foot-drop: Dropping of the front of the foot due to weakness or paralysis of the anterior muscles of the lower leg. Foot-drop results in what is called a steppage gait in which the advancing foot is lifted high in order that the toes may clear the ground. Foot drop can be due to a number of conditions including injury to the muscles that dorsiflex the foot or to the nerves to those muscles, a neuropathy, multiple sclerosis, a stroke, drug toxicity, and diabetes. Treatment may include an ankle-foot orthosis.
