The lower extremity dysfunction uses knee-ankle-foot orthosis (KAFO) that fix the movement of the knee to prevent giving way. However, because the movement of the knee is fixed, walking is difficult. So, they want the knee joint with extension stop that can fix knee to extension position during the stance phase, and flex knee during the swing phase. Therefore, we developed the stance-control (SC) system. This SC system presumes the lower limbs motion from the plantar pattern, and it controls the movement of the knee.
