ABSTRACT Objective: To analyze the impact of a physiotherapy protocol in maximum inspiratory and expiratory pressure in patients with adolescent idiopathic scoliosis (AIS) by manovacuometry. AIS may change the respiratory dynamics and the performance of inspiratory and expiratory muscles, affecting ventilatory capacity. Methods: Patients with AIS aged 10 to 20 years old were randomly assigned to receive an aerobic exercise-training program or no treatment. They were evaluated for respiratory muscle strength before and after the treatment period by means of manovacuometry, thorax and spine radiographs. Physical therapy exercising protocol comprised three weekly sessions including stretching and aerobic exercises during four months. Results: Forty five patients received physical therapy and 45 patients received no treatment (control group). The mean maximum inspiratory pressure (Pimax) was -52.13 cm H20 and the maximum expiratory pressure (Pemax) was 62.38 cm H20. There was a significant increase of Pimax and Pemax (p=0,000) in the group receiving physical therapy. There were no drop-outs and no adverse events in this study. Respiratory muscle strength, scoliosis and kyphosis degrees were not statistically correlated. Conclusion: Exercising is beneficial to patients with AIS, who have shown significant increases in respiratory muscle strength after physical therapy. There was no correlation between respiratory pressure and spine deformity. Level of Evidence I, High quality randomized trial.
