Many researchers emphasize adaptations following pregnancy. Our purpose was to get more insight into how morphology interacts with the pelvic walking pattern - the segment most prone to the adaptation following altered body demands.
Thirty women were enrolled. Three experimental sessions were arranged according to the same protocol in the first, second and third trimesters of pregnancy. First, the anthropometric measures were taken, then walking trials at a self-selected speed were registered. At the end of the experimental session the subjects were asked to fill out a questionnaire on pain.
The sagittal plane pelvic range of motion (RoM) significantly increased throughout pregnancy. There were significant positive correlations between pelvic anthropometric dimensions and pelvic tilt and rotation primarily in the third trimester of pregnancy. Significant positive correlations were found between pelvic RoM and thigh circumference. Indicators associated with body mass increase were positively correlated with pelvic obliquity in the second trimester and pelvic tilt and rotation in late pregnancy. It is also worth noting that the individual differences were not related to back pain and that the reported correlations were observed in some but not in all trimesters.
Morphological changes following the fetus growth induced increased pelvic tilt and rotation, however, pelvis movements were not associated with back pain. Overall, the results highlight correlations between morphology and pelvis kinematic patterns in some but not in all trimesters.
许多研究人员强调孕期后的适应性变化。我们的目的是更深入地了解形态学如何与骨盆行走模式相互作用，骨盆行走模式是身体需求改变后最容易发生适应性变化的部位。
招募了30名女性。在怀孕的第一、第二和第三个 trimester 按照相同方案安排了三次实验 session。首先，进行人体测量，然后记录以自我选择速度的行走试验。在实验 session 结束时，要求受试者填写一份关于疼痛的问卷。
整个孕期矢状面骨盆活动范围（RoM）显著增加。骨盆人体测量尺寸与骨盆倾斜和旋转之间主要在怀孕第三个 trimester 存在显著正相关。骨盆RoM与大腿围之间存在显著正相关。与体重增加相关的指标在怀孕第二个 trimester 与骨盆倾斜以及在怀孕后期与骨盆倾斜和旋转呈正相关。还值得注意的是，个体差异与背痛无关，并且所报告的相关性在某些但并非所有 trimester 中都观察到。
胎儿生长后形态学变化导致骨盆倾斜和旋转增加，然而，骨盆运动与背痛无关。总体而言，结果突出了在某些但并非所有 trimester 中形态学与骨盆运动模式之间的相关性。
