While the incidence of back pain during pregnancy has been shown to be high, few studies have investigated postural changes that occur during pregnancy and their relationship to back pain. The purpose of this study was to determine if posture and back pain changed from the first to the third trimester of pregnancy and whether there was a relationship between the two. Twelve healthy women who were having uncomplicated pregnancies participated in the study. During the first and third trimesters, each subject had their standing posture and back pain assessed by a Metrecom Skeletal Analysis System and a 0- to 10-cm line pain scale, respectively. Repeated measures analysis of variance and Pearson correlation coefficients were calculated on or between back pain and nine posture variables and revealed significant increases in third trimester back pain and postures compared with first trimester back pain (p < .05) and postures for lumbar angle (p < .01), posterior head position (p < .01), right pelvic sagittal tilt (p < .01), and left pelvic sagittal tilt (p < .01). No significant relationships were found between magnitude of or change in posture and back pain. These results suggest that in the standing position the lumbar lordosis and sagittal pelvic tilt increased and head position become more posterior as women progressed from the first trimester to the last trimester of pregnancy. These postural changes, however, were not related to back pain. This suggests that many of the posture-correcting clinical exercise regimens given to pregnant women need to be investigated.
虽然已表明孕期背痛的发生率很高，但很少有研究调查孕期发生的姿势变化及其与背痛的关系。本研究的目的是确定从妊娠早期到晚期姿势和背痛是否发生变化，以及两者之间是否存在关联。12名妊娠过程正常的健康女性参与了该研究。在妊娠早期和晚期，分别通过Metrecom骨骼分析系统和0至10厘米的线性疼痛量表对每位受试者的站立姿势和背痛进行评估。对背痛与九个姿势变量进行方差重复测量分析和计算Pearson相关系数，结果显示与妊娠早期相比，妊娠晚期背痛和姿势有显著增加（p < 0.05），腰椎角度（p < 0.01）、头部后位（p < 0.01）、右骨盆矢状倾斜（p < 0.01）和左骨盆矢状倾斜（p < 0.01）的姿势也有显著增加。姿势的幅度或变化与背痛之间未发现显著关系。这些结果表明，随着女性从妊娠早期进入晚期，站立时腰椎前凸和骨盆矢状倾斜增加，头部位置变得更靠后。然而，这些姿势变化与背痛无关。这表明许多给予孕妇的姿势矫正临床锻炼方案需要进行研究。
