Highlights
- •The sagittal plane pelvis movements were significantly different between trimesters.
- •Dimensions of pelvis positively correlated with its rotation and tilt in late pregnancy.
- •Pelvic mobility did not correlate with pain in the gravid women.
Abstract
Background
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.
Methods
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.
Findings
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.
Interpretation
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.
