[Purpose] The March Test (MT), evaluating hypomobility of the sacroiliac joint (SIJ), is often used in clinical practice to evaluate low back pain but has limited reported validity and reliability. Capturing the innominate movement at SIJ associated with the results of MT has not been examined. The purpose of this study was to determine if there was a significant difference in the motion of the innominate between a positive and a negative MT. [Participants and Methods] Sixteen healthy volunteers were assigned into two groups: positive or negative results of the MT. All participants were asked to perform three different tasks: standing on both limbs, static standing on one-limb and flexing the hip to 90 and 100 degrees, and active flexing the hip past 90 degrees. In a 3D motion analysis system, virtual vectors created by landmarks over the ilium defined innominate movement of the ilium related to the sacrum, which were compared between the groups. [Results] There was significantly limited innominate movement in the March Test positive group compared to the March Test negative group. [Conclusion] This study showed hypomobility at SIJ in the March test positive groups. Further investigation is needed for clinical applications.
[目的] 用于评估骶髂关节活动度降低的March试验（MT）在临床实践中常被用于评估腰痛，但报道的有效性和可靠性有限。尚未对与March试验结果相关的骶髂关节处无名骨运动进行研究。本研究的目的是确定March试验阳性组和阴性组之间无名骨运动是否存在显著差异。[参与者与方法] 16名健康志愿者被分为两组：March试验结果为阳性或阴性。所有参与者被要求执行三项不同任务：双脚站立、单腿静态站立以及将髋关节屈曲至90度和100度，以及主动将髋关节屈曲超过90度。在三维运动分析系统中，通过髂骨上的标志点创建的虚拟向量定义了髂骨相对于骶骨的无名骨运动，并在两组之间进行比较。[结果] 与March试验阴性组相比，March试验阳性组的无名骨运动明显受限。[结论] 本研究表明March试验阳性组存在骶髂关节活动度降低。临床应用还需要进一步研究。
