A mechanized crutch having vertically adjustable leg rest and body bracket, a wide tread wheel, a drive belt, gearing and a drive wheel are mounted on an elongated leg means. The leg rest and body bracket provide body support. The drive belt, gearing and drive wheel are arranged on the elongated leg means to transmit locomotive power from the drive wheel to the wide tread wheel mounted on the bottom of the elongated leg means. The drive wheel, which may be manual or battery powered, is located within reach of the user's hand on the side of his injured leg. Stabilization is provided by front and rear outrigger tubing having small wheels which roll on the walking surface.
