To the paralyzed or those otherwise enable to move on their own, we have been developing ""muscle suit"" providing muscular support. Muscle suit are worn and use a McKibben actuator driven by compressed air. Because actuators are sewn into a garment, no metal frame is needed, making a muscle suit very light and cheap. Most medical and welfare apparatuses were developing for caregivers rather than patients in need of nursing, causing patients to lose their own identity and a positive attitude. With muscle suit, they could control their movement of their own will. Muscle suit are very helpful for muscular and mental support.
