A harness designed to provide traction to the lower spine, including the lumbar and pelvic areas, with force from an external traction system. It is typically a padded piece of material (e.g., cotton, vinyl) that is placed around the waist, and has one or more straps with rings at the end that permit its attachment to the traction system's cable. It may include additional rings for attachment to a spreader bar. The harness is used mainly for relief of low back pain and to maintain normal alignment of the vertebrae.
