Hamstring tightness has been documented not to be related to the pelvic tilt position during static standing posture, but there is limited data on the relationship between hamstring muscle length (HML) and pelvic tilt range (PTR) during the dynamic movement of forward bending. This ex-post facto study was designed to compare each of HML and PTR in individuals with low back pain (LBP) and counterparts without LBP, and the relationship between HML and PTR in individuals with and without LBP. The study involved 30 purposively recruited individuals with LBP and 30 height and weight-matched individuals without LBP. Participants' PTR and HML were assessed using digital inclinometer and active knee extension test respectively. Data were analyzed using t-test and Pearson Correlation (r) at α = 0.05. Participants without LBP had significantly longer (p = 0.01) HML than those with LBP but the PTR of both groups were not significantly different. HML and PTR had indirect but not significant correlations in participants with and without LBP. Hamstring muscle length is significantly reduced in individuals with LBP but it has no significant correlation with pelvic tilt range. Pelvic tilt range reduces as hamstring muscle length increases.
已有文献记载，在静态站立姿势下，腘绳肌紧张与骨盆倾斜位置无关，但在前屈动态运动过程中，关于腘绳肌长度（HML）与骨盆倾斜范围（PTR）之间关系的数据有限。这项事后研究旨在比较患有腰痛（LBP）的个体与无腰痛个体的HML和PTR，并比较有和无LBP个体的HML与PTR之间的关系。该研究纳入了30名有目的地招募的LBP患者和30名身高体重匹配的无LBP个体。分别使用数字倾角仪和主动膝关节伸展试验评估参与者的PTR和HML。使用t检验和Pearson相关系数（r）在α = 0.05水平进行数据分析。无LBP的参与者的HML显著长于LBP患者（p = 0.01），但两组的PTR无显著差异。有和无LBP的参与者中，HML与PTR呈间接但不显著的相关性。LBP患者的腘绳肌长度显著缩短，但与骨盆倾斜范围无显著相关性。随着腘绳肌长度增加，骨盆倾斜范围减小。
