Outline of Final Research Achievements

The purpose of this study was to clarify the mechanism of instability in the one-leg standing position. The results of this study were threefold. (1) It is considered that the anteroposterior control of COP does not necessarily contribute to the control of postural sway only in the anteroposterior direction, but also affects the control of postural sway in the mediolateral direction. (2) The monotonous increase of the fast wave component of the COP frequency in the frontal plane with time may be related to the difficulty in maintaining the one-leg standing. The COP frequency in the frontal plane increased monotonically with time, which may be related to the difficulty in maintaining the one-leg standing.

Academic Significance and Societal Importance of the Research Achievements

片脚立位はバランス能力の多寡を簡便に評価でき，転倒リスクを顕在化させる有用な手法である．しかし，片脚立位保持時間が臨床的に重要視されているにもかかわらず，その姿勢保持メカニズムは明らかでなかった．本研究の結果はバランス能力の評価やその改善を目指すテーラーメイドなリハビリテーション手法の確立につながると考えられる．
