Do Flat Feet Cause Back Pain?
In a recent study, researchers found that women who have flat feet, a common condition, are 50 percent more likely to have pain in their lower back as opposed to those with normal or high arches. This study is the first of its kind to make a significant connection between low back pain and flat feet. Published in the journal Rheumatology, the study examined both men and women, measuring each subject’s arch in the standing position and how pressure was distributed on the foot while walking. To confirm and expand the findings, future studies will likely follow participants with different types of arches for a significant period of time, and will attempt to determine what effect interventions such as orthotics may have on the development of back pain. So why are women more affected by walking with flat feet than men? Marian Hannan, senior author of the study, and her team were not able to determine exact causes but suggested a few possible reasons. For example, pelvic bones in women are wider than and not as flexible as those in men, and women tend to rotate their hips and move their upper bodies more as they walk.
