Time just flies on this ergometer. On the one hand, turning the individually adjustable pedals is therapy for the foot area affected. On the other, a generator is driving, providing power for a saw. This allows the patient to work pieces of wood during therapy. The ergometer is adjusted to each individual patient by RFID chip. All adjustment possibilities were executed using maintenance-free drylin® plastic guides and spindle drives. These also stand out thanks to their low noise development.
