Outline of Final Research Achievements

The present study aimed to determine the effects of rehabilitation focusing on hip function in individuals with chronic ankle instability. This study found that exercise therapy focused on strengthening the hip muscles improved perceived ankle instability and postural balance in individuals with chronic ankle instability. These results suggest that hip-focused exercise therapy may be as effective or more effective than ankle-focused exercise therapy for individuals with chronic ankle instability. We also attempted to assess postural balance in the individuals with chronic ankle instability using inertial sensors, but the results suggested that conventional visual counting of postural sway may be sufficient for assessment.

Academic Significance and Societal Importance of the Research Achievements

スポーツ競技で非常に多い足関節捻挫再発を予防するためには，慢性足関節不安定症を改善させるためのリハビリテーションの発展が必要である．本研究は，足関節ではなく股関節を中心とした運動療法が慢性足関節不安定症の症状および機能を改善させる可能性を示唆した．これは慢性足関節不安定症に対するリハビリテーションおよび足関節捻挫再発予防プログラムの発展において意義が高いものであると考えられる．
