三维运动测量和分析方法及其在人体脊柱运动研究上应用

本文应用电测技术和刚体运动学原理．提出了一个三维运动测量和计算方法。该方法成功地用于人体腰椎活动节段的三维运动研究。实验结果表明，本文提出的方法不但可以满足离体腰椎活动节段三维运动测量和分析的要求，而且其原理同样适用于测定人体其它骨骼的三维运动变化。

An Approach for Three-Dimensional Motion Measurement and Analysis with an Application to the Motion Study of Human Spine

This paper presents an approach for three-dimensional motion measurement and analysis by applying the electric measuring technique and the kinematic principles of rigid body. The approach was successfully used in the studies of kinematics of the human lumbar motion segments. Results show that the approach offered here can not only meet the needs of measurement and analysis for three-dimensional motion of the in vitro lumtar motion segments, but also in principle be applicable to the determination of three-dimensional motions of other human body joints.
