A new method for the non-invasive three-dimensional measurement of human lumbar movement is described. The electro-magnetic 3space Isotrak system was found to be accurate and reliable, having a total r.m.s. error for rotations of less than o·2°. The system was able to produce consistent plots of subjects' movement patterns and it is proposed that this system should be evaluated in respect of its discriminatory and predictive potential in clinical studies of low back disorders. It may then become a useful tool in the routine clinical assessment of patients with spinal disorders, providing a complete quantification of back kinematics quickly and efficiently.
本文描述了一种用于人体腰椎运动无创三维测量的新方法。发现电磁3space Isotrak系统准确可靠，旋转的总均方根误差小于0.2°。该系统能够生成受试者运动模式的一致图表，并建议在腰痛疾病的临床研究中对该系统的鉴别和预测潜力进行评估。然后，它可能成为脊柱疾病患者常规临床评估中的一种有用工具，快速有效地提供背部运动学的完整量化。
