Abstract

Background: Sacroiliac joint (SIJ) movement has been investigated in many studies using a motion analysis system; however, the reliability of this method has not been well defined yet. Objectives: This study aimed to investigate the reliability of measuring the three-dimensional (3D) movement of the SIJ through the motion analysis system. Methods: A total of 10 healthy participants performed three forward flexions from a standing position twice in one session with an interval of 30 minutes. The movements were captured by the VICON motion analysis system, and the motion of the sacrum relative to each innominate was estimated in three plans of movement. The test-retest reliability was calculated with the average of three trials using the intraclass correlation coefficient (ICC) with a 95% confidence interval (CI). Results: The measurements demonstrated good to excellent reliability (ICC: from 0.61 to 0.97) that was achieved for the SIJ motion variables. Conclusion: The outcomes of this study showed that the 3D motion analysis can be used for the evaluation of SIJ mobility due to its acceptable reliability.

骶髂关节活动的三维运动分析:可靠性研究

背景:骶髂关节(SIJ)的运动已经在许多研究中使用运动分析系统进行了研究;然而，这种方法的可靠性尚未得到很好的定义。目的:本研究旨在探讨通过运动分析系统测量SIJ三维运动的可靠性。方法:共有10名健康参与者在一次会话中两次从站立位置进行3次前屈，间隔30分钟。这些运动被VICON运动分析系统捕获，并在三种运动方案中估计骶骨相对于每个无名物的运动。用类内相关系数(ICC)和95%置信区间(CI)计算三次试验的平均重测信度。结果:测量结果表明，SIJ运动变量具有良好到极好的可靠性(ICC:从0.61到0.97)。结论:本研究结果表明，三维运动分析可用于SIJ灵活性的评估，其可靠性可接受。
