Age-related balance disorder is a major risk of fall and injury. These elderlies tend to keep balance using hip strategy, and not using ankle strategy is a cause of balance disorder. Therefore, we proposed a new type balance training system, which consists of two movable plates. In this study, in order to evaluate this prototype system, we carried out the experiment in healthy elderlies. As a result, we got the knowledge that temporary transition from hip strategy to ankle strategy using prototype system (ID: 4, 6). This result indicates that prototype system is effective for specific people who use hip strategy.
