执行平面运动的身体关节的运动学特性由关节经历其全范围生理运动时的旋转中心和角度精确地限定。然而，这些潜在的（临床上）有用的非侵入性运动学参数对输入坐标测量误差和实验设计高度敏感。本文比较了实验研究的结果和统计为基础的数学模型的中心和旋转角度的错误。提供了设计最佳运动学实验的准则，以便对于给定的测量设备，可以在结果中实现尽可能高的精度。
Kinematic characteristics of a body joint performing planar motion are precisely defined by the centers and angles of rotation as the joint undergoes its full range of physiological movement. These potentially (clinically) useful non-invasive kinematic parameters are, however, highly sensitive to input coordinate measurement errors and the experimental design. This paper compares results of an experimental study and a statistically based mathematical model of the errors in the centers and angles of rotation. Guidelines are provided to design optimal kinematic experiments so that, for given measurement equipment, the highest possible precision may be achieved in the results.
