Foot drop describes the inability to lift the foot properly during gait due to muscle weakness or paralysis and may be a result of several different diseases such as Multiple Sclerosis or injuries such as a Stroke or head injury. When walking, the front part of the foot drops down and causes a shuffling of the foot or a high stepping gait. Foot drop may affect one foot (as with a stroke) or both feet (as with Charcot Marie Tooth disease).  Tratment may include the use of an ankle foot orthosis (AFO).
