温特（《生物力学杂志》1980年第13卷，923 - 927页）提出，“支撑力矩”，即矢状面伸展力矩之和，在行走过程中的变异性比任何单独的关节力矩都要小。提出了一个简单的模型来解释这一发现。建议重新定义，即髋关节和踝关节力矩现在用系数1/2加权，膝关节力矩用系数1加权。可以表明，这种形式的支撑力矩仅取决于地面反作用力的大小和膝关节角度。它在行走过程中可能表现出相对较小的变化是合理的。（C）2000爱思唯尔科学出版社。保留所有权利。
It has been suggested by Winter (J. Biomech. 13 (1980) 923-927) that the 'support moment', the sum of the sagittal extension moments, shows less variability in walking than any of the joint moments separately. A simple model is put forward to explain this finding. It is proposed to reformulate the definition, in the sense that hip and ankle moment are now weighted with a factor 1/2, and knee moment with a factor 1. It can be shown that this version of the support moment depends only on the magnitude of the ground reaction force and the knee angle. It is plausible that it will show comparatively little variation in walking. (C) 2000 Elsevier Science B.V. All rights reserved.
