Equipment and robots are being developed to support people with activities of daily living and rehabilitation. Among physical activities, walking is important for increasing physical activity and enabling social participation. In recent years, the number of frail people has been increasing due to the decrease in physical activity and the resulting frailty. In addition, people with walking disabilities due to disease may benefit greatly if robotic assistance can enable them to walk with less effort. However, since appropriate assistance differs from person to person, the determination and execution of assistance must be based on sensing of physical functions. In this study, we investigated the effects of utilizing a non-powered walking assistance robot on the walking function of frail individuals. The results showed that continuous walking practice is still effective for frail people. Regarding the difference in results depending on the direction of assistance, extension assistance tended to produce more positive results than flexion assistance to the hip joint. Lower limb gait-assist robot may improve gait function. But Depending on the person’s posture and other factors, the assistance provided may hinder achieving a comfortable gait. The feasibility of developing and commercializing more effective assistive devices and robots that integrate artificial intelligence and computational intelligence in the future needs to be further investigated.

摘要

Equipment and robots are being developed to support people with activities of daily living and rehabilitation. Among physical activities, walking is important for increasing physical activity and enabling social participation. In recent years, the number of frail people has been increasing due to the decrease in physical activity and the resulting frailty. In addition, people with walking disabilities due to disease may benefit greatly if robotic assistance can enable them to walk with less effort. However, since appropriate assistance differs from person to person, the determination and execution of assistance must be based on sensing of physical functions. In this study, we investigated the effects of utilizing a non-powered walking assistance robot on the walking function of frail individuals. The results showed that continuous walking practice is still effective for frail people. Regarding the difference in results depending on the direction of assistance, extension assistance tended to produce more positive results than flexion assistance to the hip joint. Lower limb gait-assist robot may improve gait function. But Depending on the person’s posture and other factors, the assistance provided may hinder achieving a comfortable gait. The feasibility of developing and commercializing more effective assistive devices and robots that integrate artificial intelligence and computational intelligence in the future needs to be further investigated.
