Development of fall prevention training device that can provide external disturbance to the ankle with pneumatic gel muscles (PGM) while walking
Although the average life expectancy in Japan has been increasing in recent years, the problem of the large gap between healthy life expectancy and average life expectancy is still unresolved. Among the factors that lead to the need for nursing care, injuries due to falls account for a certain percentage of the total. In this paper, we developed boots that can provide external disturbance to the ankle with pneumatic gel muscles (PGM) while walking. We experimented using an angular velocity and acceleration of the heel as evaluation indices to evaluate the effectiveness of fall prevention training using this device, which is smaller and more wearable than conventional devices. In this study, we confirmed that the developed system has enough training intensity to significantly affect the gait waveform.
