Abstract

Postural changes in pregnant women are a recognized reason of low back pain and pelvic girdle pain; however,little research has evaluated these changes. The purpose of this study was to demonstrate the characteristics of postural change in pregnant women.
The study subjects comprised 15 healthy pregnant women,17-34 weeks into pregnancy, and who had been assessed by an obstetrician prior to participation. Static digital pictures were taken to evaluate the
standing posture in a sagittal plane and two angles were measured by image analysis software as follows;
1) angle between trunk and pelvis, 2) angle between trunk and lower extremity. Spinal curvature was measured using Spinal Mouse when standing,measured from the cervical spine to sacrum. The means of sacral inclination,thoracic kyphosis,lumber lordosis,and inclination were calculated.
The relationship between principal component scores and posture evaluating data was investigated. Three distinct factors with eigenvalues of 1.08 to 2.09 were identified. These were consistent with lumbosacral spinal curvature,thoracic kyphosis,inclination of the body,and the pelvic inclination. These 3 factors accounted for 80.72% of the total variance in posture variables. Many pregnant women showed postural characteristics of thoracic kyphosis and lumbar lordosis; however,the inclination showed different patterns.
Spinal curvature of pregnant women showed flattened lumbar or lumbar lordosis and thoracic kyphosis. Pregnancy may cause changes in spinal curvature and posture,
which may produce relevant symptoms. Our
data possibly provide base-line knowledge for investigating effects of spinal curvature and postural changes on symptoms reported in pregnancy.
