Abstract
To examine the way in which posture changes during pregnancy and during the early post-natal period, measures of spinal curvature and pelvic inclination were recorded in a total of 59 women. For 16 subjects, the magnitude of lumbar and thoracic curvature in the sagittal plane and antero-posterior pelvic tilt were measured in the fourth and ninth months of pregnancy and 2 months following the birth of their infants. The latter two measures were also recorded for a further 43 subjects. Analysis revealed that both lordosis and kyphosis increased significantly during pregnancy, and that these spinal curvatures were maintained up to 2 months post-natally, so highlighting the importance of postural education before and after pregnancy.
