Outline of Research at the Start

慢性腰痛症の成因の一つに外乱に対する姿勢保持能力と体幹筋反応の低下が考えられており、特に反復する体幹回旋負荷は腰痛症発症のリスクファクターとされている。申請者らは、運動療法介入を通じて外乱に対する体幹筋反応に変化が生じることを明らかにした。しかしながら、体幹筋反応の変化により姿勢保持能力に変化が生じるかは不明である。
本研究では慢性腰痛症例の体幹回旋方向への姿勢保持能力に着目し、運動療法の介入効果を明らかにすることを目的とする。

Outline of Final Research Achievements

Delayed trunk muscle response to external disturbance has been reported to occur in patients with chronic low back pain, and delayed trunk muscle response is considered to be one of the risk factors for low back pain; however, the muscle response to external disturbance in the direction of trunk rotation has not been clarified. Analysis of trunk muscle responses to perturbations in the trunk rotation direction in patients with chronic low back pain revealed that the onset time of the agonist muscle group and the end time of the antagonist muscle group responsible for maintaining posture were significantly delayed compared to healthy participants (P < 0.001, P = 0.002). These results suggest that the trunk muscle response to a disturbance in the direction of trunk rotation is significantly delayed in patients with chronic low back pain.

Academic Significance and Societal Importance of the Research Achievements

慢性腰痛症は有病率が高く、再発を繰り返すことで生活機能や労働生産性の低下を招き、社会的にも深刻な課題となっている。本研究では、体幹回旋方向の外乱に対して主動作筋の活動開始が健常者より遅れることを明らかにし、体幹筋反応の遅延が腰痛の慢性化に関与する可能性が示唆された。これにより、従来十分に解明されてこなかった病態メカニズムの一端が示された。また、筋活動のタイミングに着目した評価視点は、介入対象の選定や訓練効果の判定にも応用可能である。今後、得られた知見を基に、運動療法を通じた予防的介入や再発予防戦略の構築が期待される。
