A descriptive and correlation approach was used to assess joint motion.
Magnitudes and directions of sacroiliac motion were examined from three different upright postural conditions.
Evidence and clinical views suggest that sacroiliac motion available in the normal case is extremely small to nonexistent.
Systems for standardizing the three postures and the Metrecom skeletal analysis system (Metrecom, Faro Technologies, Inc., Lake Mary, FL) for acquiring coordinate data for selected skeletal landmarks.
The complete sacroiliac oblique-sagittal motion that occurred between the right forward and left forward stride positions was 9 degrees (SD 6.5). The composite oblique-transverse motion was 5 degrees (SD 3.9). The motions in each plane were significantly different from zero. A joint mobility relationship existed between the hip and sacroiliac joints.
The results demonstrate that substantial angular motion is possible at the sacroiliac joints.
采用描述性和相关性方法评估关节运动。
从三种不同的直立姿势状态下检查骶髂关节运动的幅度和方向。
证据和临床观点表明，正常情况下骶髂关节的运动极小甚至不存在。
用于规范三种姿势的系统以及用于获取选定骨骼标志点坐标数据的Metrecom骨骼分析系统（Metrecom，法如科技公司，佛罗里达州玛丽湖）。
右前跨步和左前跨步位置之间发生的完整骶髂关节斜矢状面运动为9度（标准差6.5）。复合斜横断面运动为5度（标准差3.9）。每个平面内的运动均显著不同于零。髋关节和骶髂关节之间存在关节活动度关系。
结果表明骶髂关节可能存在显著的角运动。
