This longitudinal study examined the postural changes that occur during pregnancy and their association with low-back pain. The lordotic curvature, kyphotic curvature and position of the line of gravity were measured. The degree of low-back pain was assessed using a daily pain diary. Each measurement was recorded in 30 healthy pregnant women on a monthly basis until term and once post partum. The results reveal many different postural behaviours, but the majority of women experienced a flattening of the lumbar spine during pregnancy. The changes in kyphotic curvature were not so well defined. In the majority of women the position of the line of gravity was unaffected during pregnancy. Most women experienced some degree of low-back pain but in most cases it was mild. Although Pearson product-moment correlations revealed few significant correlations, the most interesting finding was that in the early stages of pregnancy, the changes in lordosis and lowback pain were inversely related.
这项纵向研究调查了孕期发生的姿势变化及其与腰痛的关联。测量了脊柱前凸曲度、脊柱后凸曲度和重力线位置。使用每日疼痛日记评估腰痛程度。对30名健康孕妇每月进行一次各项测量，直至足月，并在产后测量一次。结果显示出许多不同的姿势行为，但大多数女性在孕期腰椎出现变平。脊柱后凸曲度的变化不太明确。大多数女性在孕期重力线位置未受影响。大多数女性经历了一定程度的腰痛，但多数情况下疼痛较轻。尽管皮尔逊积差相关显示很少有显著相关性，但最有趣的发现是在孕期早期，脊柱前凸变化与腰痛呈负相关。
