Low back pain (LBP) can alters spinal kinematics. However, for adequate clinical care, a better understanding of lumbopelvic biomechanical behaviour according to the type of LBP is required. Our objectives were to identify differences in lumbopelvic rhythm (LPR) between subjects with acute low back pain (aLBP), axial spondyloarthritis (axSpA) and healthy subjects. As well as to identify correlations between LPR and sociodemographic and clinical data. In each group of 39 subjects, LPR total and by quartiles (Q) and metrological and clinical data were evaluated. No differences were found in relation to total flexion and LPR extension. However, study by Q showed less movement in aLBP compared to axSpA and healthy subjects at the Lumbar level in Q2 (p = 0.001), Pelvis in Q3 and Q4 and Trunk in Q3 (p=<0.001). In Q4 the aLBP moved the Trunk less than axSpA exclusively [-3,64°(95 % confidence interval - 6.53,-0.74), p = 0.011]. For the extension movement, the Pelvic motion of Q2 was lower for the aLBP group compared to axSpA group [-3,11°(-6.00,-0.22), p = 0.030], and Trunk motion of Q2 and Q3 (p = 0.001, p = 0.007, respectively), and Lumbar mobility of Q3 were also lower compared to axSpA and control groups (p = 0.031). Specific correlations were found for each group. aLBP with BMI, axSpA with metrology and Healthy subjects with age. Subjects with aLBP showed less lumbar, pelvic or trunk movement in Q2 and Q3 of trunk flexion and extension movements than axSpA and controls. RPL and its interrelationships with sociodemographic and clinical variables depend on the lumbar condition.
下腰痛（LBP）会改变脊柱运动学。然而，为了提供充分的临床护理，需要更好地了解根据下腰痛类型的腰骶部生物力学行为。我们的目标是确定急性下腰痛（aLBP）、轴性脊柱关节炎（axSpA）患者与健康受试者之间腰骶节律（LPR）的差异。以及确定LPR与社会人口统计学和临床数据之间的相关性。在每组39名受试者中，评估了LPR总量、四分位数（Q）以及测量和临床数据。在总屈曲和LPR伸展方面未发现差异。然而，按四分位数研究显示，在Q2的腰椎水平（p = 0.001）、Q3和Q4的骨盆以及Q3的躯干方面，与axSpA和健康受试者相比，aLBP的运动较少（p<0.001）。在Q4中，aLBP使躯干的运动比axSpA单独减少[-3.64°（95%置信区间 - 6.53，-0.74），p = 0.011]。对于伸展运动，与axSpA组相比，aLBP组Q2的骨盆运动较低[-3.11°（-6.00，-0.22），p = 0.030]，Q2和Q3的躯干运动（分别为p = 0.001，p = 0.007）以及Q3的腰椎活动度与axSpA组和对照组相比也较低（p = 0.031）。每组都发现了特定的相关性。aLBP与体重指数相关，axSpA与测量相关，健康受试者与年龄相关。与axSpA和对照组相比，aLBP患者在躯干屈伸运动的Q2和Q3中，腰椎、骨盆或躯干的运动较少。RPL及其与社会人口统计学和临床变量的相互关系取决于腰椎状况。
