An improved electronic braking system for walkers that incorporates one or more electrically-operated brakes controlled by an electronic controller is disclosed. The controller is responsive to touch-sensitive switches for easy operation, and is adjustable and responsive to operator patterns of use to provide individualized control of the brake operation. The controller may also be responsive to environmental conditions such as the slope of the ground over which the walker is moving, to its rate of motion, or to the distance between the walker frame and the user, and may be adjusted to accommodate for the weight of the user or to set limits to the speed at which it can move.
