What is it indicated for?

The TM-300 Traction System is indicated for relief of pain in cases of low back pain. Each treatment consists of a physician-prescribed session designed to provide static, intermittent, or cycling distraction forces to relieve pressure on structures that may be causing low back pain. The TM-300 relieves pain associated with herniated discs, protruding discs, degenerative disc disease, posterior facet syndrome, and sciatica. It achieves these effects through decompression of intervertebral discs, that is, unloading due to distraction and positioning.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
