RELAÇÃO ENTRE MOBILIDADE DIAFRAGMÁTICA COM VARIÁVEIS CLÍNICAS E FUNCIONAIS EM PACIENTES COM DPOC

RELATIONSHIP BETWEEN DIAPHRAGMATIC MOBILITY WITH CLINICAL AND FUNCTIONAL VARIABLES IN PATIENTS WITH COPD

Abstract

To evaluate if there is a relationship between the diaphragmatic mobility with oral and pharyngeal transit time, predictor of mortality Body mass index, airflow Obstruction, Dyspnea and Exercise capacity (BODE) index score, dyspnea and health status in patients with Chronic Obstructive Pulmonary Disease (COPD). A cross-sectional study, with evaluation of following outcomes: diaphragmatic mobility (ultrasonography), oral and pharyngeal transit time (videofluroscopy), predictor of mortality (BODE index score), dyspnea (modified Medical Research Council – mMRC scale) and health status (COPD Assessment Test). Participated in this study 19 patients with clinical diagnosis of COPD stages GOLD II or III (65.9 ± 7.9 years of age, 11 male, FEV₁ 47.76 ± 21.91% predicted). There was a strong negative correlation between diaphragmatic mobility with BODE index score (r=-0.822; p<0.0001), moderate negative correlation with pharyngeal transit time in the liquid consistency (r=-0.508; p=0.02) and moderate negative correlation with dyspnea (r=-0.527; p=0.02). Multivariate regression analysis showed that the increase of diaphragmatic mobility was negatively associated with BODE index (β=-5.21; p<0.001; CI 95% -7.28 to -3.15) and with pharyngeal transit time in the liquid consistency (β=-13.65; p<0.08; CI 95% -29.16 to 1.86). There was no correlation between the diaphragmatic mobility and the oral transit time (liquid and pasty consistency), with the pharyngeal transit time (pasty consistency) and health status. It is suggested that in patients with COPD the diaphragmatic mobility is associated with BODE index, pharyngeal transit time in the liquid consistency and dyspnea.
