This machine is a table which has a system of rollers that rise up thru a hole in the center of the table. When a patient lays on their back , the rollers gently roll up and down the SPINE increasing MOTION in the spine. This MOTION elongates the muscles and ligaments of the spine allowing more flexibility in the spine. This action also helps reduce adhesions in the spinal joints, thus decreasing the stiffness of ARTHRITIS.
