A wheelchair having a therapeutic unit attached thereto that contains an auxiliary drive wheel mounted in a frame beneath the chair seat. A pair of leg operated levers are connected to the auxiliary drive wheel by a drive system so that reciprocating the levers causes the auxiliary drive wheel to rotate. The levers contain forwardly extended arms that are hinged to move laterally to one side or the other of the chair seat thus permitting easy ingress and egress from the chair. The auxiliary drive wheel can be raised by one seated in the chair so that the therapeutic value of the system can be realized while the chair is in a stationary position.
