三维关节运动学的实验研究需要描述和测量六个运动分量。任何描述方法的一个重要方面是它能够轻松地传达给使用数据的人。本文提出了一个关节坐标系，它提供了两个刚体之间三维旋转和平移运动的简单几何描述。该坐标系应用于膝关节，并与膝关节运动的常用临床术语相关。空间连杆共享的坐标系的一个便利特征是，大的关节位移与组件平移和旋转发生的顺序无关。
The experimental study of joint kinematics in three dimensions requires the description and measurement of six motion components. An important aspect of any method of description is the ease with which it is communicated to those who use the data. This paper presents a joint coordinate system that provides a simple geometric description of the three-dimensional rotational and translational motion between two rigid bodies. The coordinate system is applied to the knee and related to the commonly used clinical terms for knee joint motion. A convenient characteristic of the coordinate system shared by spatial linkages is that large joint displacements are independent of the order in which the component translations and rotations occur.
