Abstract：
Patients with sacroiliac joint dysfunction are limited in daily life activities such as gait, climbing stairs and rising from a chair. It is well known that individuals with chronic low back pain have impaired balance compared to healthy individuals. This cross-sectional case-control study aims to investigate spatiotemporal parameters, center of pressure and mass, pelvic angles and other joint angles in patients with sacroiliac joint dysfunction in comparison with healthy controls.
Motion analysis existed of three tasks: (1) normal gait, (2) single-leg-stance, and (3) sit-to-stance. Spatiotemporal parameters, center of pressure, pelvic angles and other joint angles were measured using a twelve-camera, three-dimensional motion capture system and ground reaction force platforms.
Thirty subjects were recruited for this study; ten patients, ten matched controls and ten healthy student controls. For gait, patients had a lower cadence, longer double support phase, shorter step length and slower walking speed than controls. For single-leg-stance, patients had a smaller hip angle of the risen leg than controls. Also, variability in center of pressure was larger in patients. For sit-to-stance, the total time to perform the task was almost doubled for patients compared to controls.
This study demonstrates that patients with sacroiliac joint dysfunction have an impaired gait, more balance problems during standing and standing up compared to healthy controls. This novel information assists to further comprehend the pathology and disease burden of sacroiliac joint dysfunction, in addition, it may allow us to evaluate the effect of current therapies.

摘要：
背景：骶髂关节功能障碍患者在步态等日常生活活动中受到限制，爬楼梯，从椅子上站起来。众所周知，与健康个体相比，患有慢性下腰痛的个体平衡受损。这项横断面病例对照研究旨在调查时空参数，压力和质量的中心，与健康对照组相比，骶髂关节功能障碍患者的骨盆角和其他关节角。
方法：运动分析存在三个任务：（1）正常步态，(2)单腿站立，和（3）坐姿。时空参数，压力中心，骨盆角和其他关节角使用12台摄像机测量，三维运动捕捉系统和地面反作用力平台。
结果：本研究招募了30名受试者；10名患者，十个匹配的对照和十个健康的学生对照。对于步态，患者的节奏较低，更长的双支持阶段，比控制更短的步长和更慢的步行速度。对于单腿站立，与对照组相比,患者的上升腿髋部角度较小.此外，患者的压力中心变异性较大.为了坐姿，与对照组相比,患者执行任务的总时间几乎增加了一倍.
结论：这项研究表明，骶髂关节功能障碍患者的步态受损，与健康对照相比，站立和站立时的平衡问题更多。这种新颖的信息有助于进一步理解骶髂关节功能障碍的病理和疾病负担。此外,它可以让我们评估当前疗法的效果。
