Light to moderate exceercise during pregnancy is benifical for mother and foetus. It is unclear, however it is usefull in the prevention of low back and pelvic girdle pain. The results of this meta- analysis has been demonstrated that excercise during pregnancy appears to reduce low back pain and associated sick leave, but there is no clear evidence for an effect on pelvic girdle pain.

To evaluate the impact of exercise on pelvic girdle pain, low back pain and correlated sick leave.

EMBASE, Google Scholar, ClinicalTrials.gov databases, PubMed, Cochrane Library, and ResearchGate were searched from the beginning through May 2017 to collect the related data. Randomised controlled trials (RCTs) were suitable for inclusion if they involved comparison of an exercise with regular daily activities and at least some of the subjects were free from pelvic girdle pain and/or low back pain at baseline. Cochrane Collaboration's tool was used to measure the methodological quality of included studies. A random-effects meta-analysis was conducted, and publication bias and heterogeneity were evaluated.

A total of 11randomised controlled trials were selected for the meta-analyses. Exercise decreased the risk of low back pain during pregnancy by 9%, although it had no protecting impact on lumbopelvic pain or pelvic girdle pain. Moreover, exercise stopped new incidents of sick leave that occurred due to lumbopelvic pain. No evidence of publication bias was noticed.

Exercise seems to decrease the risk of low back pain among pregnant women, and sick leave due to lumbopelvic pain, although no clear evidence for an impact on pelvic girdle pain was seen.
