正常运动的研究需要了解运动和所涉及的力的作用。在理解病理性步态的问题时也是如此。步态周期描述的重要事件发生在站立和摆动阶段。简要介绍了步行力作用分析的基本原理。一个简单的例子,在手肘关节的力的行动被认为是和分析外推提供一个关于运动的一般性声明。这涉及由于行走中的力效应和关节本身中的相应力而抵抗关节处的转动动作所需的肌肉动作。与联合行动有关的信息的常规显示被考虑并与实际情况进行比较。在矢状面运动的“棒图”是用来识别和讨论的行动在关节的腿在步行。比较这和病理性步态,特别是膝上截肢者。
A study of normal locomotion requires an understanding of both the movements and the force actions involved. This is equally true in appreciating the problems of pathological gait. The gait cycle is described in terms of the significant events which occur during both the stance and swing phases. The basic principles underlying the analysis of force actions in walking are briefly described. A simple example of force actions in the elbow joint is considered and the analysis extrapolated to provide a general statement regarding locomotion. This relates to the muscle actions required to resist turning actions at joints due to the force effects in walking and the corresponding forces in the joints themselves. The conventional display of information relating to joint actions is considered and compared with the actual situation. “Stick diagrams” of motion in the sagittal plane are used to identify and discuss the actions at the joints of the leg in walking. Comparisons are made between this and pathological gait—in particular that of the above-knee amputee.
