Foot drop does not happen on its own. It is typically caused by nerve damage, which can stem from several underlying causes. Foot drop dramatically affects gait, and this is often one of the first signs that someone has developed the condition. Foot drop can happen to anyone at any age. The underlying cause will generally determine the treatment.
A person with foot drop cannot lift the front part of one or both feet due to weakness or paralysis of the muscles required for this motion. Foot drop makes it difficult to walk normally because the individual's toes slide along the ground. To compensate, the person must lift their knees higher when they walk. Foot drop can affect one foot or both feet and, as a symptom of an underlying problem, may be temporary or permanent depending on the cause.
