"Foot drop” refers to the inability to lift the front part of one’s foot off the ground when walking, resulting in a scuffing or dragging of the foot or lifting the thigh (known as “steppage” gait). It is most often caused by nerve or muscle disorders or damage, or by a central nervous system disorder.
Foot drop is usually diagnosed by physical examination, although additional testing may be recommended in some cases. Treatment may include use of braces, physical therapy, and electrical nerve stimulation. In some cases surgery may be required.
