Modular hand tiller system for joystick operation of powered wheelchairs

A method has been developed for assembling a hand support tiller that mounts to the post of a joystick controller of an electrically powered wheelchair. The hand tiller can be custom-designed by the therapist to fit the size, shape, and position of the user's hand. This results in a functional hand grasp that is necessary for the safe operation of the powered wheelchair. The design of the modular hand tiller system consists of low-cost, commercially available plastic tubing and fittings. This allows for an efficient set-up, easy modification, and durability.
