It is easy to screen yourself, your children, or your friends from home by using a scoliometer or a  bubble-level app on your smart phone to measure the degree of rotation. Simply have the person bend over, and measure the two greatest areas of rotation. If the angle of trunk rotation (ATR) is greater than six degrees, it is a good idea to get physician evaluation, and a full-length x-ray taken to see if scoliosis is present. If scoliosis is present, conservative methods such as Schroth therapy, a physical therapy technique focusing on elongating the spine, and 3D-CADCAM (Rigo-Chenau)  bracing can help to stop and/or reverse the scoliosis.   This may prevent later quality of life issues, and life-long curve progression. and possibly prevent the need for invasive surgical treatment. Weinstein found that curves under 30 degrees tended not to progress during adulthood — so we want to FIND scoliosis under 30 degrees, and try to “KEEP IT IN THE GREEN ZONE” –  under 30 degrees if possible, with conservative therapies.
