Pregnant women sometimes contact medical professionals about low back pain caused by pregnancy. The load to facet joint is considered to be the cause. In this study, we evaluated the lumber spinal and pelvic alignment of pregnant women. The subjects were 30 healthy women (average age was 21.8±7.0 years old, average height was 159.0±4.6 cm, average weight was 55.2±9.3 kg). They wore the pregnant women’s experience jacket. The average value of the grade of the lumbar loadsis was larger with the pregnant women’s experience jacket (10.7±5.0 degrees) than without the pregnant women’s experience jacket (5.7±3.5 degrees) ( p<0.0001). The average value of the grade of the pelvic anteversion was larger with the pregnant women’s experience jacket (11.8±3.0 degrees) than without the p pregnant women’s experience jacket (24.2±5.0 degrees) ( p<0.0001). It was suggested pregnancy increases the grade of the lumbar loadsis and the pelvic anteversion. Our result may become the grounds to prevent facet syndrome caused by pregnancy.
