缺乏足够的腰盆腔运动控制被认为是导致下腰痛和下肢病变发展和持续的潜在机制。本研究的目的是评估会话内和会话间的可靠性（即区分受试者的能力），以及在功能运动控制任务中矢状面腰骨盆运动学的一致性（即重复测量的分数是否相同）。运动学测量采用便携式惯性测量单元系统。20名健康受试者（平均年龄= 22（+/- 3.6）岁，15名女性）在两种情况下执行四项任务，间隔5至7天：站立（SB），从地板上抬起一个盒子（LIFT），站到坐到站（SIT）和将一个盒子放在架子上（OVERH）。参与者被要求在任务中保持腰椎处于中性前凸状态。计算腰椎和髋部与中性起始位置的最大偏差。用类内相关性（ICCs）、测量标准误差（SEM）、最小可检测变化和95%一致性限来评估可靠性和一致性。SB和LIFT为基本可靠（ICC = 0.89-0.96）， SIT为中等至基本可靠（ICC = 0.69-0.92）， OVERH为相当至中等可靠（ICC = 0.40-0.67）。腰椎的SEMs在1.1度到3.1度之间，髋关节的SEMs在0.7度到4.8度之间。基于可靠的可靠性和可接受的一致性，SB和LIFT最适合量化功能性任务期间的腰盆腔运动控制。(c) 2017 Elsevier Ltd.版权所有。
A lack of adequate lumbopelvic movement control has been suggested as an underlying mechanism contributing to the development and persistence of low back pain and lower limb pathologies. The purpose of this study was to assess the within and between session reliability (i.e. the ability to discriminate between subjects), and the agreement (i.e. whether scores are identical on repeated measures) of lumbopelvic kinematics in the sagittal plane during functional movement control tasks. Kinematics were measured with a portable inertial measurement unit system. Twenty healthy subjects (mean age = 22 (+/- 3.6) years, 15 females) performed four tasks on two occasions, five to seven days apart: standing bow (SB), lifting a box from the floor (LIFT), stance-to-sit-to-stance (SIT) and placing a box on an overhead shelf (OVERH). Participants were asked to keep the lumbar spine in a neutral lordosis during the tasks. The maximal deviations from the neutral starting position for the lumbar spine and hip were calculated. Intraclass correlations (ICCs), standard errors of measurement (SEM), minimal detectable changes and 95% limits of agreement were used to assess reliability and agreement. SB and LIFT were substantially reliable (ICC = 0.89-0.96), SIT was moderately to substantially reliable (ICC = 0.69-0.92) and OVERH was fairly to moderately reliable (ICC = 0.40-0.67). SEMs ranged between 1.1 degrees and 3.1 degrees for the lumbar spine and between 0.7 degrees and 4.8 degrees for the hip. Based on the substantial reliability and acceptable agreement, SB and LIFT are most appropriate to quantify lumbopelvic movement control during functional tasks. (c) 2017 Elsevier Ltd.
