[Purpose] The aim of this study was to analyze changes in thoracic and lumbar spinal motions during running in a female athlete with scoliosis. [Participant and Methods] A female with scoliosis who was a member of a college track team was recruited for this study. On 1.5-T magnetic resonance imaging, angles between bodies of adjacent vertebrae in the frontal plane were calculated. We measured real-time spine movement while running using a three-dimensional motion analysis system, wherein the running speed was altered (6, 9, and 12 km/h). [Results] We observed a Cobb angle of 29.0° and the right convex curvature of the thoracolumbar spine on magnetic resonance imaging. As the running speed increased, during the right stance phase, the participant increased the lateral bending angle of the thoracic spine to the left and the lumbar spine to the right. However, during the left stance phase, the runner bent the thoracic spine to the right and the lumbar spine to the left, indicating a decreased convex curvature of the spine. [Conclusion] As the running speed increased, the convex curvature of the spine was corrected during the left stance phase but was uncorrected during the right stance phase.
[目的]本研究旨在分析一名脊柱侧弯女运动员跑步过程中胸腰椎运动的变化。[参与者与方法]本研究招募了一名大学田径队的脊柱侧弯女性。在1.5-T磁共振成像上，计算额状面相邻椎体之间的角度。我们使用三维运动分析系统在跑步过程中测量实时脊柱运动，其中跑步速度有所改变（6、9和12 km/h）。[结果]我们在磁共振成像上观察到Cobb角为29.0°，胸腰椎脊柱向右凸。随着跑步速度增加，在右支撑相期间，参与者增加了胸椎向左和腰椎向右的侧弯角度。然而，在左支撑相期间，跑步者将胸椎向右弯曲，腰椎向左弯曲，表明脊柱凸度减小。[结论]随着跑步速度增加，脊柱凸度在左支撑相期间得到矫正，但在右支撑相期间未得到矫正。
