Apparatus for permitting exercise by a bedridden patient includes a patient bed having guard rails extending generally along one side and with a bracket supported by the rails. A motor is carried by the bracket, the motor having a drive shaft extending generally normal to the rails and toward the bed. A crank arm is fixed at one end to the drive shaft and dimensioned substantially shorter than the distance between the drive shaft and the surface of the bed, with a handle or footstrap at the other end of the crank arm for permitting a hand or foot of the patient to be coupled to the crank arm so that the patient may exercise by rotation of the crank arm and the drive shaft.
