In recent years, the population that requires assistance with walking has increased owing to a decrease in leg muscular power with age. To prevent muscle weakness and expand their sphere of activities, we develop the orthosis for walking assistance using a pneumatic artificial muscle to assist leg muscular power. In order to judge the availability of the orthosis, we measure the effect on assistance quantitatively. EMG and step length are measured with assistance on healthy subject. We observed that the EMG of the sartorius muscle, which helps swing the leg forward, decreased. And step length is increased as a result of assistance. I think these results mean that a person with little muscular strength can walk like a healthy person.
