| Outline of Final Research Achievements |
The purpose of this study was to clarify postural control plasticity accompanied by motor growth and development. Four- to nine-year-old children maintained upright standing quietly on a force platform. We evaluated performance, cost and efficiency of postural control calculated by center of foot pressure. Results of this study suggest that, in preadolescent children at least, the cost of postural control decreases with age, and that upright stance has tendency to be controlled more efficiently with age.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、COPの標準偏差および平均速度を、それぞれ姿勢制御のパフォーマンスと制御コストと解釈し、その比から制御効率を評価した点、および制御効率が年齢とともに減少する傾向が示された点が新たな知見である。加齢や疾病にともなう姿勢制御の差異を評価する指標として有用である可能性が期待できる。
