For her project Macy chose to research Lordosis and how it affects a pregnant woman’s spine, which relates to the objective, “Explain common disorders during pregnancy and their cause.” Lordosis is a very exaggerated curving of the spine that affects the lower back. As we can see in the first drawing of her project not all lordosis is bad, a little bit of that curvature is necessary so that we are able to move and absorb shock so we don’t hurt ourselves. It’s when this curve gets too big that it’s an issue.
As a woman enters the second trimester of pregnancy the spine naturally becomes more inward because it is trying to keep the weight balanced. Researchers at Harvard University suggest that overtime the female spine has naturally evolved itself to help support the woman during pregnancy and the change in center of gravity. As we can see in the second drawing of Macy’s project, the line of the center of gravity has moved forward. We can also see that the back now has more of an arch to it, again due to the change in the center of gravity for the body.
It’s in the third trimester where we see Lordosis in its full effect. Researchers used a tool called the BackMapper to measure just how much the spine actually changes throughout a pregnancy. They discovered, when compared to a control subject aka someone who isn’t pregnant, that the curvature of the spine actually increases by three degrees. We can see this in the third drawing of Macy’s project, in how the back now has a substantially larger arch in it and that the lumbar spine is now far more curved.
