Investigators recently performed a research review on the relationship between lower back pain and lumbar lordosis (curve) using data concerning 796 low back pain patients and 927 healthy controls from a total of 13 published studies. The researchers found that overall, lower back pain patients tended to have a smaller lumbar lordotic curve than those without back pain. Furthermore, the research team observed that the loss of lumbar lordotic curvature is significantly associated with lower back pain caused by either disk herniation or disk degeneration.
