Size Wide (18"-20") * The Theratrac gently stretches neck muscles allowing the vertebral discs to realign, freeing the nerve root tissue from the pressure of the discs * The Theratrac helps "locked" neck muscles to slowly stretch and relax, allowing misaligned vertebrae to resume their normal supportive position * The Theratrac cradles the head and neck via a curvature in the neck portion of the device, as well as a special head rest section that is vertically pneumatic * 5 year limited warranty
Both the headrest and neck region, inflate with over 30 lbs of adjustable pneumatic pressure to create traction in the cervical curve
