Scoliosis Medical Association" (2003) asserted the lifelong physical health, including cardiopulmonary and neurological functions, and mental health of idiopathic scoliosis patients are comparable to those of the general population. Scoliosis that interferes with normal systemic functions is "exceptional" and "rare", and "untreated [scoliosis] patients had similar death rates and were just as functional and likely to lead productive lives 50 years after diagnosis as people with normal spines". In an earlier University of Iowa follow-up study, 91 percent of idiopathic scoliosis patients displayed normal pulmonary function, and their life expectancy was 2% longer than that of the general population. Generally, the
Neuromechanics of idiopathic scoliosis factor and how they may interact is not clearly defined. The earlier the scoliosis appears, the more likely it will progress. Though it is recommended that idiopathic scoliotic people should practice a sport for aerobic exercise and development of a positive body image, practice of a sport at a competitive level is to be avoided. Idiopathic scoliosis can appear at different ages. Infantile idiopathic scoliosis that appear from the birth to 3 years old, account for 0.5% of idiopathic scoliosis. Juvenile idiopathic scoliosis that appear from the 4 to 10 years old, account for 10.5% of idiopathic scoliosis. Adolescent idiopathic
