While sagittal trunk inclinations alter upper body biomechanics, little is known about the extent of frontal trunk bending on upper body and pelvis kinematics in adults during gait and its relation to sagittal trunk inclinations. The objective was to determine the effect of the mean lateral trunk attitude on upper body and pelvis three-dimensional kinematics during gait in asymptomatic subjects. Three gait cycles were collected in 30 subjects using a motion analysis system (Vicon 612) and an established protocol. Sub-groups were formed based on the mean thorax lateral bending angle, bending side, and also sagittal tilt. These were compared based on 38 peak angles identified on pelvis, thorax and shoulder kinematics using MANOVAs. A main effect for bending side (p = 0.038) was found, especially for thorax peak angles. Statistics revealed also a significant interaction (p = 0.04993) between bending side and tilt for the thorax sagittal inclination during body-weight transfer. These results reinforce the existence of different gait patterns, which correlate upper body and pelvis motion measures. The results also suggest that frontal and sagittal trunk attitude should be considered carefully when treating a patient with impaired gait.
虽然矢状面躯干倾斜会改变上半身的生物力学，但对于成年人在步态过程中额状面躯干弯曲对上半身和骨盆运动学的影响程度及其与矢状面躯干倾斜的关系，我们知之甚少。目的是确定无症状受试者在步态过程中平均侧方躯干姿态对上半身和骨盆三维运动学的影响。使用运动分析系统（Vicon 612）和既定方案，收集了30名受试者的三个步态周期。根据平均胸部侧方弯曲角度、弯曲侧以及矢状面倾斜度形成亚组。使用多变量方差分析，基于在骨盆、胸部和肩部运动学上确定的38个峰值角度对这些亚组进行比较。发现弯曲侧存在主效应（p = 0.038），尤其是对于胸部峰值角度。统计数据还显示，在体重转移过程中，胸部矢状面倾斜度的弯曲侧和倾斜度之间存在显著交互作用（p = 0.04993）。这些结果强化了不同步态模式的存在，这些模式将上半身和骨盆运动测量联系起来。结果还表明，在治疗步态受损的患者时，应仔细考虑额状面和矢状面躯干姿态。
