    Abstract:
    Chest physical therapy techniques are essential in order to reduce the frequency of recurrent pulmonary infections that progressively affect lung function in cystic fibrosis patients. Recently, ELTGOL (L'Expiration Lente Totale Glotte Ouverte en décubitus Latéral) emerged as an inexpensive and easy to perform therapeutic option. The aim of this study was to compare the acute effects of ELTGOL and the Flutter valve in stable adult patients with cystic fibrosis. [Subjects and Methods] This was a randomized, crossover study with a sample of cystic fibrosis outpatients. The subjects underwent two protocols (Flutter Valve and ELTGOL interventions, referred to as ELTGOL and FLUTTER) in a randomized order with a one-week washout interval between them. The main outcomes were pulmonary function variables and expectorated sputum dry weight. [Results] ELTGOL cleared 0.34 g more of secretions than FLUTTER (95% CI 0.11 to 0.57). When comparing the physiological effects of ELTGOL and FLUTTER, the first was superior in improving airway resistance (-0.51 cmH2O/L/s; 95% CI -0.88 to -0.14) and airway conductance (0.016 L/s/cmH2O; 95% CI 0.008 to 0.023). [Conclusion] ELTGOL promoted higher secretion removal and improvement in airway resistance and conductance than the Flutter valve. These techniques were equivalent in reducing the pulmonary hyperinflation and air trapping in cystic fibrosis patients.
