title: Multipurpose ergometer for static and dynamic exercise of the calf muscles.
abstract: A calf ergometer is presented that can be used for both static and dynamic exercise in supine, sitting or standing position. During exercise each foot is fixed firmly to a pedal. During dynamic exercise the foot pedal can rotate through an angle which can be varied from 5 to 30 degrees. External work is performed only during plantar flexion. The amount of work is determined by the moment imposed to the pedal by a constant force spring and can be calculated from electrical signals that represent the angle of rotation and the moment exerted to the pedal. During static exercise the foot pedal is secured so that it cannot move.
