ABSTRACT:
An exercise device offers different levels of exercise to an individual and can be arranged as an exercise device for bedridden patients and those in different stages of rehabilitation. The device comprises an exercise head having at least one pair of crank arms for rotation of limbs of the individual about an axial shaft. A hydraulic motor is linked to the axial shaft to rotate the crank arms with hydraulic power source for the motor. Rotational speed of the axial shaft is set by a speed adjustment arrangement associated with the hydraulic motor. A force adjustment system adjusts the force applied to the limbs through the crank arms to rotate the axial shaft beyond a set rotational speed. Variation in the speed of the axial shaft is sensed by a speed sensing arrangement. A system for sensing force to sense variation in force applied to the crank arms by the limbs of the individual.
