Outline of Final Research Achievements

It was clarified that healthy elderly people can perform posture control strategies that stabilize the center of gravity (COM) and reduce the variation of joint movements by visual feedback of the COM during one leg standing (OLS). However, healthy elderly people, like young people, could not enhance the coordination structure of joint movement by visual feedback of the center of gravity. In addition, the posture control strategy with less variation of joint movement in the lower limbs was used to maintain OLS in the patients with mild knee OA. This suggests that visual feedback of the COM to the patients with mild knee OA cannot enhance the coordination structure of joint movement and may be a factor in the progression of knee OA.

Academic Significance and Societal Importance of the Research Achievements

軽度膝OA患者の段階でも，片脚立位保持において下肢の関節運動のばらつきを減じた戦略により，適切な筋活動のコントロールが困難となり，OA進行の要因となっている．このことから，軽度膝OA患者においても早期から適切な筋活動を再獲得する理学療法が重要であることが明らかとなり，進行予防につながれば社会的医療的経済効果に繋がる可能性がある．
