DTS Spinal Decompression Therapy is FDA cleared and has been clinically proven with an 86% success rate for pain associated with herniated or bulging discs...even after failed surgery. It is a non-surgical, traction therapy for the relief of back and leg pain or neck and arm pain. During this procedure, by cycling through distraction and relaxation phases and by proper positioning, a spinal disc can be isolated and placed under negative pressure, causing a vacuum effect within it.
