[Purpose] We aimed to investigate the relationship of thoracic asymmetry in standing position with asymmetry of the internal ankle moment in the frontal plane during gait. [Participants and Methods] The following measurements were recorded in 22 healthy adult males using a 3D motion analyzer and force plates: thoracic lateral deviation, asymmetrical ratios of the upper and lower thoracic shape, internal ankle moment in the frontal plane, mediolateral deviations of the center of mass and center of pressure. [Results] In the standing position, the thorax was deviated to the left relative to the pelvis, and the upper and lower thoracic shapes were asymmetrical. During gait, significant lateralities were observed in the internal ankle moment in the frontal plane, mediolateral deviations of the center of mass and the center of pressure. Significant positive correlations were observed between the asymmetrical ratio of the lower thoracic shape and both the asymmetry of the internal ankle moment in the frontal plane and the mediolateral deviation of the center of pressure. [Conclusion] These results suggest that thoracic asymmetry is associated with mediolateral control of the ankle during gait.
[目的]我们旨在研究站立位时胸廓不对称与步态期间额状面内踝力矩不对称之间的关系。[参与者与方法]使用三维运动分析仪和测力板对22名健康成年男性进行了以下测量：胸廓侧方偏移、上下胸廓形状的不对称比率、额状面内踝力矩、质心和压力中心的内外侧偏移。[结果]在站立位时，胸廓相对于骨盆向左偏移，上下胸廓形状不对称。在步态期间，观察到额状面内踝力矩、质心和压力中心的内外侧偏移存在显著的偏向性。下胸廓形状的不对称比率与额状面内踝力矩的不对称以及压力中心的内外侧偏移之间均存在显著的正相关。[结论]这些结果表明，胸廓不对称与步态期间踝关节的内外侧控制有关。
