Foot drop, or drop foot, is a condition in which a patient has difficulty raising or lifting the front part of the foot.
Foot drop may result in a patient dragging their foot, and can affect the way a patient walks, forcing them to lift their knee higher than normal or swing their leg to the side in order to keep the foot from dragging.
Foot drop can affect one or both feet at the same time; it can be temporary or permanent; and it can happen at any age.
Foot drop is generally caused by an underlying neurological or muscular issue, such as a weakness or paralysis of the muscles that lift the foot. This can be the result of a nerve injury or a type of nerve, brain or muscle disorder.
