In this study, we verified that stand-up training using a special cushion was superior to general walking training in terms of walking endurance for elderly people with decreased walking ability. The subjects were elderly people who were hospitalized in a convalescent ward and needed supervision or minor assistance when walking. The evaluation items were the increase in 6-minute walking distance[m] as walking endurance, and the increase in isometric knee extension muscle strength to body weight ratio[%] as lower limb muscle strength. As a result, it was found that performing standing training using a training cushion to improve gait training ability produced the same effect in a shorter time as compared to general gait training. Furthermore, shortening the training time to obtain the same effect means shortening the intervention time for ward staff, which is thought to lead to a reduction in the burden on ward staff.
