title: Cross-over comparison between respiratory muscle stretch gymnastics and inspiratory muscle training.
abstract: OBJECTIVE
  To compare the effect of respiratory muscle stretch gymnastics (RMSG), proposed as a possible additional form of rehabilitation for patients with chronic obstructive pulmonary disease (COPD), with that of inspiratory muscle training (IMT).
  
  
  METHODS
  Twelve naive outpatients with COPD at a university hospital.
  
  
  METHODS
  The patients performed IMT (2 sessions of 10 minutes of training at 30% of PImax, daily) for 4 weeks and RMSG (3 sessions of 5 RMSG patterns 4 times each, daily) for 4 weeks, in randomized order, with a 4-week washout period between the two interventions.
  
  
  RESULTS
  PImax increased with IMT (mean 66.1 to 79.1 cmH2O), but not with RMSG (mean 66.0 to 69.4 cmH2O). RMSG and IMT similarly increased maximum chest wall expansion. FRC was significantly decreased by 158 ml with RMSG, but not with IMT. There were no significant changes in VC, FEV1, or PEF nor in arterial blood gases with either form of rehabilitation. Six-minute walking distance was more significantly increased with RMSG (mean 383 to 430 m), than with IMT (mean 386 to 412 m).
  
  
  CONCLUSIONS
  RMSG may have clinically significant benefits, which may be somewhat different from the benefits of IMT, in patients with COPD.
