According to a recent study published in journal Rheumatology outlined in Reuters Health, flat feet might be a cause for low back pain. The study suggests that “women who walk with flat feet are 50 percent more likely than those with normal or high arches to have low back pain.”
Among 1,930 men and women recruited from Framingham, Massachusetts, pronated feet – which tend to roll inward as a person walks – were linked to lower back pain in women only.
“The key takeaway from the study is that if women have low back pain, it may not be just the back,” said senior author Marian Hannan of the Institute for Aging Research at Hebrew SeniorLife in Boston.
Women in the study were in their 60s, on average. About 38 percent overall reported having low back pain.
