The Scoliometer, model 5055, is designed for use by physical therapists and other medical professionals to measure curvature of the spine. It measures six areas to detect scoliosis, and provides three measurements to detect abnormal anteropostero curves. It can be used to evaluate progress during treatment, without X-rays. It also measures the unstable lumbosacral curve as well as the cervical and thoracic curves. The device is calibrated in centimeters, millimeters, and degrees. It is latex-free and comes with instructions.
