Relieve lower back pain. Perform physically demanding activity. Maintain mobility and a healthy lifestyle. The Nubax operates on the very simple principal of leverage. By kneeling into the device and leaning forward, the trunk of your body becomes suspended over a common pivot point, while being held at either end of your back, hip and shoulders, a strong gentle traction is created along your spine as gravity forces each end to move apart around the pivot point. The Nubax Trio is a functional therapeutic device that provides traction therapy that can be effective in Occupational Health, Sports and Exercise, Pain Management or Pre-activity Warmup. Best of all, this device can be used in the privacy of your home. Nubax Trio is lightweight, compact, portable, and designed to accommodate a wide variety of body shapes.
