and prevent back injuries, and a recent study inidcates that the MedX might even prevent back surgery. In the study, 60 patients who were surgical candidates did resistive extension exercise on the MedX. Forty-six of the 60 participants completed the program, with only three of them requiring surgery.
The MedX works by strengthening the musculature of the back and increasing its range of motion, both of which have been found to decrease back pain. While exercising the lower back, the MedX restraints inhibit the use of the pelvis and legs. "This is key, since the major extensors of the back are the buttocks muscles and hamstring muscles," says
Marc Darrow, Medical Director of the Joint Rehabilitation and Sports Medical Center in Los Angeles, California. "The muscles surrounding the vertebrae are usually weak even when the gluteus and hamstring muscles are strong. Once these muscles are strengthened and range of motion with MedX is increased, pain diminishes."
