Several biomechanical factors were recorded intermittently in 855 pregnant women from the 12th to the 36th week of gestation and were related to back pain occurrence during pregnancy. The three factors related to the development of back pain were abdominal sagittal diameter, which correlated with back pain, with a coefficient of 0.15 (P < 0.01); transverse diameter (r = 0.13, P < 0.01); and depth of the lumbar lordosis, which correlated with a coefficient of 0.11 (P < 0.01). In the group of women who were pregnant for their first time, there was a significantly lower peripheral joint laxity in the 12th week in those women who, later in pregnancy, developed back pain. These correlations suggest that back pain in pregnancy can not be explained primarily by biomechanical factors.
在855名孕妇妊娠第12周到36周期间间歇性记录了几个生物力学因素，并将其与孕期背痛的发生情况相关联。与背痛发展相关的三个因素分别是腹矢状径，其与背痛的相关性系数为0.15（P < 0.01）；横径（r = 0.13，P < 0.01）；以及腰椎前凸深度，其相关性系数为0.11（P < 0.01）。在初产妇组中，孕期后期出现背痛的女性在第12周时外周关节松弛度明显较低。这些相关性表明，孕期背痛不能主要由生物力学因素来解释。
