MotionFoot ® Prosthetist Manual Introduction The MotionFoot MX is a hydraulic ankle with carbon fiber foot system that provides a full 50 degrees ® range of motion (ROM). Plantar flexion and dorsi flexion resistance are independently adjustable by the prosthetist or the patient. Dynamic response of the toe lever arm progressively increases during the gait cycle due to the unique, moving fulcrum design acting on the main spring element of the foot.
