Introduction: The adolescent idiopathic scoliosis (AIS) causes changes on the compliance of the chest. These changes may be associated with impaired lung function and reduced functional exercise capacity of these adolescents. We aimed to evaluate the correlation between functional exercise capacity, lung function and geometry of the chest at different stages of AIS. Materials and methods: The study was carried out in a crosssectional design which were evaluated 27 AIS patients at different stages of the disease. For chest wall evaluation, were created geometry angles/distances (A/D), which were quantified by Software Postural Assessment. The functional exercise capacity was assessed by a portable gas analyzer during the incremental shuttle walk test (ISWT). Besides that, manovacuometry and spirometry were also performed. Results: Linear regressions showed that oxygen uptake (peak VO2) was correlated with distance travelled in the ISWT (R2 = 0.52), maximal respiratory pressures, cough peak flow (R2 = 0.59) and some thoracic deformity markers (D1, D2 and A6). Discussion: We observed that the chest wall alterations, lung function and respiratory muscle strength are related to the functional exercise capacity and may impair the physical activity performance in AIS patients. Final considerations: There is correlation between functional exercise capacity, lung function and geometry of the chest in AIS patients. Our results point to the possible impact of the AIS in the physical activities of these adolescents. Therefore, efforts to prevent the disease progression are extremely important.Downloads
