Outline of Final Research Achievements

During walking, patients with hip osteoarthritis use their whole body (especially the upper body) in a compensatory manner to control their center of mass, while reducing the range of motion of the impaired hip joint. In addition, it was suggested that the hip joints of patients, compared to normal subjects, undergo coordinated compensatory movements to maintain a constant inter-trial angle during the stance phase. Furthermore, it was suggested that maintaining hip range of motion (especially external rotation) may be important to control center of gravity movement, and that maintaining range of motion and muscle strength, especially external rotation, may contribute to suppression of progression during conservative treatment.

Academic Significance and Societal Importance of the Research Achievements

変形性股関節症患者の歩容の改善は、病態の進行予防に重要である。本研究の結果、変形性股関節症患者に認められた歩容の変化は、重心や股関節角度に対して合目的的に構成された運動様式である可能性が明らかとなった。進行に関連する力学的負荷を減少させることを目的に、歩行中の重心や股関節角度の制御を可能にするために、必要な身体機能を検討したことで、保存療法における介入方針の提案の一助になると期待できる。
