“There is some evidence that chiropractic is an effective treatment for lower back pain. This means that scientific trials conducted to investigate the effect of chiropractic on lower back pain found that it did have a beneficial effect. But because of disagreements over the way the trials were carried out, and over what their results mean, this evidence does not allow us to draw definite conclusions. Some scientists believe that the best fair tests show that chiropractic is not effective for lower back pain. More research is needed before firm conclusions can be drawn. NHS Choices website
