The kinematics of the pelvis and thorax are important in gait studies since their movement patterns are closely related to gait efficiency and 'smoothness' of locomotion. The purpose of this study was to identify features of normal gait patterns for later comparisons with pathological and developmental gait patterns. A two camera SELSPOT system interfaced with an HP1000 minicomputer was used to obtain three-dimensional kinematic/temporal data for the pelvis and thorax. Data from treadmill walking of eight adults were used for within subject (at different speeds) analyses. The analyses revealed a very complex pattern with a set of breakpoints which was consistent over all subjects. Some features were invariant over a range of walking speeds although the total range of motion changed considerably.
骨盆和胸廓的运动学在步态研究中很重要，因为它们的运动模式与步态效率和运动的“流畅性”密切相关。本研究的目的是识别正常步态模式的特征，以便日后与病理和发育性步态模式进行比较。使用与惠普1000小型计算机相连的双摄像头SELSPOT系统来获取骨盆和胸廓的三维运动学/时间数据。来自八名成年人在跑步机上行走的数据用于受试者内部（不同速度下）的分析。分析揭示了一个非常复杂的模式，其中有一组断点，在所有受试者中都是一致的。尽管运动的总范围有很大变化，但一些特征在一系列步行速度范围内是不变的。
