This paper is on development of an active ankle foot orthosis (AAFO). This device will fill the gap in the existing research aimed at helping patients with drop foot muscle deficiencies as well as rehabilitation activities. Drop foot patients are unable to lift their foot because of reduced or no muscle activity around the ankle. The major causes of drop foot are severing of the nerve, stroke, cerebral palsy and multiple sclerosis. There are two common complications from drop foot. First, the patient cannot control the falling of their foot after heel strike, so that it slaps the ground on every step. The second complication is the inability to clear the toe during swing. This causes the patients to drag their toe on the ground throughout the swing.
