Methods: 12 subjects with stroke diagnosis (54.5±9.7 years, BMI: 27.1±3.1, FVC%: 89.6±13, FEV1/FVC%:102.0±8.6, PImax%:76.3±27, PEmax%:89.4±24) were included in the study. On day 1 of the protocol anthropometric characteristics, respiratory muscles strength and lung function were collected. On day 2 and 3, OEP values were collected during the use of Vo-IS and 3 levels of PEP (10, 15 and 20 cmH2O). Results: RR was significantly higher during the use of PEP compared to Vo-IS (Mean: 11.8±4.7 vs. 5.5±2.3 min-1) (p<0.0001) while inspiratory (5.7±1.8 vs. 2±0.7), expiratory (6.3±2 vs. 4.1±1.9) and total respiratory cycle (12.2±3.3 vs. 6.1±2.3) time were significantly higher during Vo-IS compared to PEP (p<0.0001). Tidal volume (VT) was significantly increased during the use of Vo-IS compared to quite breathing for CW and its compartments (p<0.05) while the use of 15 and 20 cmH2O of PEP showed significantly higher values for VTCW only (p<0.05).VT was significantly higher in Vo-IS compared to PEP in all compartments (p<0.05).Conclusion: Vo-IS induced higher modifications on breathing pattern and CW volumes compared to different intensities of PEP. %U
