While this study only takes into account the treatment of a single 56-year-old man suffering from chronic low back pain resulting from sciatica due to lumbar disc herniation, it is nevertheless significant. Despite being previously reated by three chiropractors before becoming the subject of this clinical study, the patient began recovering during the 26 weeks of lumbar extension traction (inversion therapy). There was no relapse reported eight years after these treatments took care of his pain and discomfort.
