Analgesia Assisted Traction Therapy (IVSAATT) frees muscle and joint adhesions. Muscles and joints are gently extended through their full natural range of motion. This procedure provides relief in about 90% of the patients treated. Many of them are actually able to stop taking the muscle relaxants commonly prescribed for this problem. The potential effectiveness of the procedure is determined by whether or not the stretching and exercise do anything to restore your range of motion and flexibility.
