Treino de músculos inspiratórios em doentes com DPOC

AbstractAim: The aim of this study was to evaluate the impact a specific inspiratory muscle training (IMT) protocol had on dyspnoea, lung function, respiratory muscle pressure, tolerance to exercise and quality of life in a group of patients with ch ronic obstructive pulmonary disease (COPD)Population: We studied 13 patients with moderate to very severe COPD divided into a control group (n=5) with an average FEV1 43.9±10.1% of predicted value and an IMT group (n=8) with FEV1 57.8±12.1 % of predicted value. While this study group underwent IMT for five consecutive weeks, the control group did not undergo any kind of training.Results: Using a specific IMT protocol significantly improved maximal inspiratory pressure (MIP) in the study group (initial MIP – 83.3±21.4 versus final MIP- 98.4±17.8 cmH2O; p<0.01). The same result was seen with the St. George Respiratory Questionnaire (SGRQ) score in the study group (initial score 58±2.2 versus final score 50±2.1; p
