[Purpose] This study determined whether the results of the mobility assessment of pelvic and thoracic rotation (static evaluation), which is often used in clinical settings, are related to step length asymmetry. Moreover, we identified the postural evaluation of rotation that may be related to gait asymmetry. [Participants and Methods] We hypothesize that a certain relationship exists between the static assessments of pelvic rotation and step length asymmetry. Fifteen healthy adult males participated in static posture and gait motion analyses using a motion-capture system. The static evaluation was analyzed using three parameters: pelvic rotation in standing, pelvic rotation with kneeling, and thorax rotation in sitting. [Results] The relationship between the asymmetric variables obtained from static evaluation and gait observations demonstrated a significant correlation. The asymmetric variables of step length and asymmetric variables of thorax rotation in sitting showed a significant relationship. Furthermore, significant correlations were found between asymmetric variables of pelvic rotation during gait and asymmetric variables of step length and between asymmetric variables of pelvic rotation during gait and asymmetric variables of thorax rotation in sitting. [Conclusion] This study revealed asymmetric relationships between thorax rotation in sitting test and step length asymmetry in the gait. Asymmetry in the thorax rotation in sitting may be caused by a gait with biased pelvic rotation.
[目的] 本研究确定临床环境中常用的骨盆和胸廓旋转活动度评估（静态评估）结果是否与步长不对称有关。此外，我们确定了可能与步态不对称相关的旋转姿势评估。[参与者与方法] 我们假设骨盆旋转的静态评估与步长不对称之间存在某种关系。15名健康成年男性使用动作捕捉系统参与了静态姿势和步态运动分析。静态评估使用三个参数进行分析：站立时骨盆旋转、跪姿时骨盆旋转和坐姿时胸廓旋转。[结果] 静态评估获得的不对称变量与步态观察之间的关系显示出显著相关性。步长的不对称变量与坐姿时胸廓旋转的不对称变量显示出显著关系。此外，步态期间骨盆旋转的不对称变量与步长的不对称变量之间以及步态期间骨盆旋转的不对称变量与坐姿时胸廓旋转的不对称变量之间均发现显著相关性。[结论] 本研究揭示了坐姿胸廓旋转测试与步态步长不对称之间的不对称关系。坐姿胸廓旋转不对称可能由骨盆旋转偏向的步态引起。
