Objectives: Evaluate the effects of RMS on ventilatory pattern and thoraco-abdominal kinematics in hemiplegic volunteers after stroke. Methods:Clinical trial crossover study (randomized and blind) was conducted with 10 patiens with hemiplegia, divided into two groups: respiratory muscle stretching (SG) and control (CG). The intervention consisted of a sequence of 4 kinds of RMS with two sets of ten repetitions for each kind. The CG remained at rest for 20 minutes. The ventilatory pattern and thoraco-abdominal kinematics were evaluated before and immediately after each intervention by optoelectronic plethysmography. Results: The SG showed an increase in tidal volume (CG = 0.45 ± 0.11 and SG = 0.55 ± 0.14), minute volume (CG = 7.8 ± 2.1 and SG = 10.4 ± 3.5), inspiratory flow (CG = 0.3 ± 0.07 and SG = 0.38 ± 0.1) and expiratory flow (CG = 0.24L ± 0.08 and SG = 0.35 ± 0.17) after the intervention, in addition to increase the total volume of the rib cage (CG = 0.24L ± 0.05 and SG = 0.28 ± 0.07 ) and pulmonary rib cage (CG = 0.07L ± 0.02 and SG = 0.09 ± 0.05) in the hemiplegic side compared to the CG. Conclusions: The findings suggest that the RMS produces an increase in lung volumes decreasing the restrictive component arising with the hemiplegia, and generate a higher contribution of the hemiplegic side over the total volume of the rib cage.
