Abstract
Our country is facing an aging society with fewer children. Percentage of the total population over the age of 65 in 2007 is greater than 21[%], Japan has become a super-aged society. It is expected the rate of aging is going to rise in the future. In this study, we propose the development of a walking assist device that is intended to assist in muscular strength of elderly people to walk safely in daily life. In this paper, we described the structure of the walking assist device, and verify the effectiveness of the device from the results of the EMG during walking attached the device. In addition, we also introduce a system which wearer can adjust the timing of the assist speed depending on walking speed, and explain their effect.
