The effects of inspiratory muscle training for patients with pulmonary disease in outpatient rehabilitation

Background: The effects of inspiratory/respiratory muscle training are widely investigated. Positive effects in healthy humans are established (Hart N. et al. 2011). Beckerman et al. 2005 attested an increase of maximal inspiratory pressure (Pi max), distance of 6 minute walking test and Borg Scale data in COPD patients. The main objective of this study was to determine the optimal intensity and frequency of inspiratory muscle training (IMT) in outpatient rehabilitation. Methods: 42 patients were randomized in a training group (with IMT) and control group (no IMT). The patients started with a low load (20 – 30%…
