Abstract: A therapeutic wheelchair that includes an auxiliary frame attached to the main frame of the wheelchair. An auxiliary drive wheel is mounted in the auxiliary frame and is coupled through a drive linkage to a pair of leg operated levers whereby the auxiliary drive wheel is rotated as the levers are moved up and down to propel the wheelchair. A lifting mechanism is provided for raising the auxiliary drive wheel so that the wheel can be driven through the levers without propelling the wheelchair to provide therapy to a person confined to the chair or alternatively, allowing the chair to be used in a conventional manner.
