Força muscular respiratória e pico de fluxo expiratório de pacientes com bronquiectasia submetidos à reabilitação respiratória

Abstract

ObjectiveThis research aimed to evaluate the respiratory muscle strength and peak expiratory flow in patients with bronchiectasis undergoing respiratory rehabilitation. MethodClinical trial where, after scrutiny of inclusion and exclusion criteria, the sample was divided randomly into experimental group (EG, n=13, age = 60±14.86 years) – who underwent treatment with respiratory rehabilitation twice week, lasting 40 minutes per session, at 12 weeks and control group (CG, n=13, age = 58±13.90 years) – patients with conservative clinical follow-up without therapy during the period of research because they were part of a waiting list for care. The dependent variables of the study were respiratory muscle strength (maximal inspiratory pressure – MIP- expiratory pressure – MEP) and peak expiratory flow (PEF), measured by the manometer and the peak flow®, respectively. The level of significance was set at p<0.05. ResultsIn within groups comparison, there was a significant increase only in the EG variables, namely: MIP (Δ=18.08cm H2O, p<0.001) and MEP (cmH2O Δ=12.31, p<0.001) and PEF (Δ=26.77l / min, p=0.016). In the between groups comparison, increased satisfactory post-test, GE, compared to GC in MIP and MEP (p=0.005). Conclusionit appears that physical therapy influences the proposed increase in respiratory muscle strength and peak expiratory flow in patients with bronchiectasis.
