Scoliosis is an abnormal curvature of the spine. The normal shape of a person’s spine includes a curve at the top of the shoulder and a curve at the lower back. If your spine is curved from side to side or in an “S” or “C” shape, you might have scoliosis.According to the American Association of Neurological Surgeons (AANS), about 80 percent of scoliosis cases have no identifiable cause. The condition is often diagnosed during the first seven years of a child’s life. Scoliosis can also be categorized as either structural or nonstructural. In structural scoliosis, the spine’s curve is caused by a disease, injury, or birth defect, and is permanent. Nonstructuralscoliosis describes temporary curves that can be fixed.cerebral palsy, a group of nervous system disorders that affect movement, learning, hearing, seeing, and thinking
