弾性ストリングを用いる歩行補助デバイスの アシスト効果の筋骨格シミュレータを用いた検討

抄録

In recent years, the aging of society has led to a shortage of labor force and other social problems. As a solution to this problem, we propose the development of non-powered assist device. In order to prevent stumbling, which is a major cause of falls in the elderly, the non-powered assist device increases the foot clearance by generating a torque that promotes dorsiflexion at the ankle joint during the stance phase, thereby preventing stumbling. The non-powered assist device was found to be effective in reducing the risk of falls in the elderly on flat roads, but the effect in everyday walking environments such as slopes and stairs has not been verified. In addition, since no analysis using a simulator has been conducted, the accuracy of the results cannot be said to be high. Therefore, in order to evaluate the adaptability of the non-powered assist device on flat roads, slopes, and stairs, we conduct walking experiments on these three walking environments, and compare and verify the walking parameters between assisted and unassisted walking using musculoskeletal simulator.
