Tobias JH, et al. - Researchers performed the first prospective population-based study reporting the association between physical activity and scoliosis. Self-reported measures of physical ability/activity at ages 18 months and 10 years were obtained in the Avon Longitudinal Study of Parents and Children (ALSPAC) and by means of accelerometry, objective measures of physical activity were collected at age 11 years. They used the dxa scoliosis Method at age 15 years to detect scoliosis. In this study, they did not include participants with scoliosis at age 10 years. According to findings, reduced physical ability and activity were observed as early as age 18 months in those who go on to develop scoliosis by age 15 years.
