People that suffer from lower back pain are more likely to share a spine shape resembling that of a chimpanzee than a person with no back or disc problems. Researchers compared and analyzed spine shapes of humans, orangutans, and chimpanzees to look for a relationship between the shapes, health, and movement of the spines. They found that people with lower back pain often had a lesion in the spinal discs that was responsible for the differing shape. This research will be useful as a diagnostic tool in terms of seeing which people are most at risk for developing lower back pain.
