Foot drop, sometimes called "drop foot," is the inability to lift the front part of the foot. This causes the toes to drag along the ground while walking.
To avoid dragging the toes, people with foot drop may lift their knee higher than normal. Or they may swing their leg in a wide arc.
Foot drop can happen to one foot or both feet at the same time. It can strike at any age.
In general, foot drop stems from weakness or paralysis of the muscles that lift the foot. It can have many different causes. Treatments for foot drop vary according to the cause.
