Disclosed is a limb exerciser mainly including an outer wheel housing and an inner wheel set in the outer wheel housing. With frictional members disposed between the contact surfaces of the outer wheel housing and the inner wheel, as well as actuating members oppositely disposed at two sides of the inner wheel, the inner wheel can be rotated relative to the outer wheel housing by pushing or pedalling the actuating members to produce frictional force or resistance and thereby helps the user to conveniently take hand or foot exercise at a desk top or on a floor or ground.
An active and continuous passive motion (CPM) devices for exercising and/or providing therapy to the upper and lower extremities comprising a frame, a disc pivotally mounted to the frame and hand or feet support members attached to the disc. A motor is provided and is coupled to the disc for rotating the disc in the active mode. A control circuit is provided for adjusting the speed of the disc in the passive mode and for adjusting the resistance to movement of the disc in the active mode.
