| Research Abstract |
In normal pregnant women, pelvic floor muscles relax during the course of the pregnancy, but the force of contraction is maintained. Meanwhile, it could be that in the first trimester pelvic floor muscles of pregnant women with cervical incompetence are already more relaxed than those of normal pregnant women. There were differences in the force of pelvic floor muscle during the second trimester, but no significant differences in the state of pelvic floor muscle at 36 weeks of gestation or later between two groups. During pregnancy, hormones allow the cartilage of the pubic symphysis and ligaments of the sacro-iliac joint to become slightly flexible, causing the birth canal to dilate. This study suggested that widening of the pelvis associated with pregnancy is a phenomenon that occurs regardless of the presence or absence of abnormality during the course of the pregnancy, because of no significant differences between two groups.
