Outline of Final Research Achievements

Recently the knee valgus(KV) is much focused on as one of the biggest causes of the anterior cruciate ligament injury (ACL). The KV is a dynamic malalignment of lower extremities that during landing, cutting, and stopping, pivoting foot cannot manage to absorb stress, as its knee is flexed, it is forced to be bended inward. In order to prevent the KV balance training to improve trunk stability and pelvic flexibility around the hip is considered essential. In this study, we investigated how effect on pelvic function the continuous pelvic training we devised would have. In parallel, we investigated whether our training could improve the contraction of transversus abdominis muscle (TAM) using a sonography, which automatically controls pelvic motion, and whether improvement of pelvic mobility and the TAM’s contraction could correct the KV using a 3-dimensional motion analyzer. Our results showed clear improvement in pelvic function, but no improvement in the TAM’s contraction and the KV.

Academic Significance and Societal Importance of the Research Achievements

動的下肢アライメント障害の一つで、膝前十字靭帯損傷の原因となるKVを改善・予防するために、我々は体幹の安定化機能の向上を目指して新しい骨盤訓練を開発した。本研究では、新しい骨盤訓練を継続的に行うことで、1)骨盤機能の改善が得られるか、2)超音波エコーを用いて、骨盤運動の改善により腹横筋の収縮能が強化され、骨盤運動の自動制御が可能となるか、3)3次元動作解析装置を用いて、骨盤運動の自動制御がKVの改善に繋がるかを調査した。結果は、腹横筋の収縮能やKVの改善は得られなかったが、骨盤他動運動の改善は明らかで、本法による骨盤機能の改善は、腰椎や下肢スポーツ障害の予防に貢献し得る可能性が期待される。
