PURPOSE
Pregnancy is characterized by many musculoskeletal changes that affect daily living activities and walking. The purpose of this study was to examine the effect of pregnancy on pelvic and trunk kinematics, and their relationship during the three pregnancy trimesters.
METHODS
Three-dimensional pelvis and trunk motions were measured using Qualisys Gait Analysis System in the first, second and third trimesters of pregnancy. The maximum anterior pelvic tilt and maximum trunk flexion during stance phase, pelvic tilt, obliquity and rotation, as well as trunk flexion-extension, lateral bending and rotation were measured.
RESULTS
Repeated-measures analysis of variance showed a significant increase in the maximum anterior pelvic tilt during stance phase ( p = 0.005), and a significant decrease in the pelvic obliquity ( p = 0.011), maximum trunk flexion during stance phase ( p = 0.0006), trunk lateral bending ( p = 0.005) and trunk rotation ( p = 0.004). A significant negative correlation was found between maximum anterior pelvic tilt and maximum trunk flexion in the first (r = -0.72, p = 0.008), second (r = -0.61, p = 0.03), and third (r = -0.61, p = 0.03) trimesters of pregnancy. Also, there was a significant positive correlation found between pelvic obliquity and trunk lateral bending in the first (r = 0.76, p = 0.04), second (r = 0.59, p = 0.04), and third (r = 0.59, p = 0.04) trimesters of pregnancy.
CONCLUSIONS
The pregnant women walk with an increased maximum anterior pelvic tilt, a decreased maximum trunk flexion, a decreased pelvic obliquity, as well as a decreased trunk lateral bending and rotation. Pregnancy does not affect the relationship between pelvis and trunk motions.
目的
怀孕的特征是许多肌肉骨骼变化，这些变化会影响日常生活活动和行走。本研究的目的是研究怀孕对骨盆和躯干运动学的影响，以及它们在怀孕三个阶段的关系。
方法
使用Qualisys步态分析系统测量怀孕第一、第二和第三阶段的三维骨盆和躯干运动。测量站立期最大前骨盆倾斜度和最大躯干屈曲度、骨盆倾斜度、倾斜和旋转度，以及躯干屈伸、侧弯和旋转度。
结果
重复测量方差分析显示，站立期最大前骨盆倾斜度显著增加（p = 0.005），骨盆倾斜度显著降低（p = 0.011），站立期最大躯干屈曲度显著降低（p = 0.0006），躯干侧弯（p = 0.005）和躯干旋转度（p = 0.004）。在怀孕的第一（r = -0.72，p = 0.008）、第二（r = -0.61，p = 0.03）和第三（r = -0.61，p = 0.03）阶段，最大前骨盆倾斜度与最大躯干屈曲度之间存在显著负相关。此外，在怀孕的第一（r = 0.76，p = 0.04）、第二（r = 0.59，p = 0.04）和第三（r = 0.59，p = 0.04）阶段，骨盆倾斜度与躯干侧弯之间存在显著正相关。
结论
孕妇行走时最大前骨盆倾斜度增加，最大躯干屈曲度降低，骨盆倾斜度降低，躯干侧弯和旋转度降低。怀孕不影响骨盆和躯干运动之间的关系。
