Protocol comprise 3 moments: quite breathing (QB), volume-oriented IS (3 series/10 repetitions) and recovery quite breathing (rQB).The tidal volumes of chest wall in EG was lower compared to the CG, in QB (0.4vs0.61L), IS (1.8vs2.3 L) and rQB (0.4vs0.5 L) (p<0.0001). The tidal volume increase in chest wall 75% in EG and 73.3% CG during IS. Different pattern of breathing were found in tidal volume in EG compared to CG on ab compartment: QB(54.1%vs43.7%), IS(43.3%vs40.9%) and rQB(48.9% vs. 46.2%); RCab compartment, QB(13.8%vs16.8%), IS(19%vs20.6%) and rQB(15.2%vs17.2%) and RCp compartment, QB(30.7%vs37.9%), IS(37.7%vs39.9%) rQB(32.9%vs37.3%). Right and left hemithorax volume were different in EG, QB (ΔVt=0.06±0.04 ml vs 0.02±0.02 ml, p=0.002), IS(ΔVt=0.09 ±0.07 ml vs. 0.07±0.05 ml) and rQB(ΔVt= 0.07±0.07 vs 0.02±0.03 ml) independent of stroke side impairment.Chest wall volumes are decrease in patients with chronic stroke. IS induces improvements in volume of chest wall in both groups; however, more pronounced in chronic stroke patients determining a breathing pattern similar that was observed in healthy subjects. ER -
