Abstract Resume

Background:Individuals with adolescents idiopathic scoliosis (AIS) have reduced funcional capacity of exercise during the Incremental Shuttle Walk Test (ISWT), however, the effect of
surgery on this test is not known yet. Therefore, the aim of this study was to evaluate the travelled distance on the Incremental Shuttle Walk Test (ISWD) and observe the physiological responses
during ISWT in patients with adolescent idiopathic scoliosis in the late postoperative period (LPO). Concomitantly, evaluate respiratory muscle strength, lung function and correlate the variables with
Cobb angles.


Methods:Twenty-two adolescents with EIA (GE) and twenty-one healthy controls (CG), were submitted to evaluation of maximal inspiratory and expiratory pressures (MIP and MEP), forced
vital capacity (FVC) and forced expiratory volume in first second (FEV1). Two ISWT were performed and analyzed only the value of the second travelled distance in ISWT. During the second test,  the
participantes used a gas analyzer and were obtained: oxygen consumption  at peak exercise (VO2), carbon dioxide production (VCO 2), tidal volume (VT), respiratory rate (RR), heart rate (HR ) and their
relationships.


Results:It found significantly lower values for variables in EG: VO2 (22 ± 5 vs. 27 ± 4 ml / kg / min) ISWD (± 94 567 ± 86m vs.604), FVC (2.70 ± 0.47 vs . 0,52L ± 3.33) and FEV1 (2.41
± 0.46 vs. 2.84 ± 0.52 L). There was no differences in respiratory pressures. We have obtained significant correlations between ISWD, VO2 (r = 0.70) and VO2 / kg (r = 0.80), and correlations between
VO2 and OUES (Oxygen Uptake Efficiency Slope) with the breathing pattern (r = 0.51 r = 0.65, respectively), which was significantly lower in GE. Moderate correlations were observed between VO2 and
OUES (r = 0.67), also observed between main thoracic curve with VO2 (r = -0.41) and VO2 / kg (r = -0.61).


Conclusions:Patients with adolescent idiopathic scoliosis in late postoperative period show significant reduction in functional exercise capacity associated with reduced lung
function, residual curvature and physical deconditioning.
