Resumo
The weakness of the respiratory muscles is the main responsible for respiratory failure in Duchenne Muscular Dystrophy (DMD). Objective. Evaluate the effects of inspiratory muscle training on respiratory strength in patients with DMD. Method. A clinical trial of single group of five children with DMD, aged 11.4±2.6 years, assessed by Manovacuometry and Peak Expiratory Flow (PEF) for the initial time (baseline), fifth and tenth session . Held inspiratory muscle training, with 30% of PImax in linear load (Threshold<sup>®</sup>) device with five sets of 10 repetitions, totaling 10 sessions, three times a week. Results. Mean values initial, fifth and 10th session, respectively: PImax (cmH2O):-64 ,-69.8 and-86.8 (p=0.006) improvement of 29% in 10 sessions; PEmax (cmH2O) : 64 , 67 and 73.6 (p=0.003) improvement of 25% in 10 sessions and PEF (L/min): 210 , 218 and 232 (p=0.012) improvement of 9% in 10 sessions. Conclusion. The inspiratory muscle training program proposed proved to be effective in both the inspiratory and expiratory force gain, providing also the increased peak expiratory flow.
