The aim of this project is to verify the effect of the global postural reeducation (GPR) intervention used in physiotherapy on scoliosis progression (scoliosis angle), back pain, quality of life, respiratory function, trunk posture and trunk muscle functioning and walking endurance. To do so, we will recruit 144 participants at three scoliosis specialized Centers. Participants will be randomly allocated to the standard of care (SC) group (observation or brace plus home video of exercises for 12 months) or to the GPR group (SC plus individual sessions once a week for 6 months and individual sessions alternating with telerehabilitation sessions once per two weeks between 6 and 12 months). At initial, 6, 12- and 24-months evaluation, participants will have x-ray, complete self-report questionnaires to document back pain and quality of life. Thereafter, measurement of trunk posture, electromyography activity of the back muscles, excursion of the diaphragm muscle using echography and respiratory function as well as distance covered using the 6-minute walk test for walking endurance will be done. We believe that GPR intervention may prevent scoliosis progression and improve physical health and quality of life in adolescence.
