Outline of Final Research Achievements |
The purpose of this study was to identify factors associated with excessive pelvic movement during the hip abduction test in persons with low back pain, and to construct an exercise regimen to improve the factors found to be associated. This study found that the recurrent low back pain patients showed a large difference in the asymmetry of the timing of lateral pelvic tilt and the pelvic wobble in the transverse plane, and delayed activity of the transversus abdominis/medial oblique abdominis and erector spinae muscles during the active hip abduction test. Therefore, changed muscle activity pattern was considered to be a factor in the decreased motor control of the lumbopelvic region. In addition, the results suggest that motor control training with visual feedback is useful as exercise therapy to improve the motor control of the lumbopelvic region during active hip abduction test in patients with low back pain.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,股関節外転運動時の骨盤動揺やその因子について調査した。その結果、腰痛者では股関節外転運動時の骨盤の挙上や回旋量に左右差が生じ、筋活動パターンが健常者と異なり体幹筋の活動が遅延することが示された。このような異常な筋活動パターンや骨盤の非対称な運動パターンが日常的に繰り返されることで片側への組織ストレスが増加、蓄積し腰痛の再発や悪化につながる可能性が示唆された。 また股関節外転運動時の過剰な運動パターンを改善させる方法として視覚的フィードバックを用いた運動介入を実施することで腰椎骨盤の運動制御が改善した。これは再発性腰痛者の運動プログラム作成時の一助となり学術的に意義がある。
