Abstract

Aim: 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 chronic 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 FEVI 43.9 +/- 10.1% of predicted value and an IMT group (n=8) with FEVI 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<0.05). No changes were recorded in the variables studied in the control group. Conclusions: The use of IMT in patients with moderate to very severe COPD induced an improvement in inspiratory muscle force with a consequent improvement in the quality of life in relation to symptoms.
