Foot drop (also called drop foot) is a term used to describe the inability to lift one or (rarely) both feet at the ankle. Foot drop is not a disease in and of itself, but a sign of underlying neurological, nerve or muscle dysfunction. A person afflicted with foot drop may drag the top of his foot as he walks, slap it down on the floor or raise his thigh unusually high in order to lift his foot completely off of the ground.
