Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Low back and posterior pelvic pain are common in pregnant females. Previous studies have demonstrated disability and it is estimated that all women experience some degree of musculoskeletal discomfort during pregnancy. Borg-Stein et. al. found 25% of pregnant females have temporarily disabling symptoms. There is demonstrated controversy over the mechanism of low back pain in pregnancy. The biomechanical theory implies that the enlarging uterus causes the maternal center of gravity to move anteriorly causing stress on the low back. Jensen et. al. demonstrated that weight gain correlated with biomechanical changes. The changes were measured by weight gain in segmental regions of the body and in principal moments of inertia from the sit to stand movement. Literature does not demonstrate a specific correlation between weight gain and the biomechanical changes of sway rate, lumbosacral angle and center of gravity. These three measurements may have a correlating effect on the underlying cause of low back pain in pregnant women. This study aims to determine the correlation between weight gain of pregnant females and the biomechanical changes of sway rate, lumbosacral angle and center of gravity. The change in weight over the last two trimesters will be correlated with the sway rate, lumbosacral angle and center of gravity. The degree of symptomatic low back pain as measured by the Oswestry Low Back Pain Scale will also be correlated with the sway rate, lumbosacral angle and center of gravity.
