Abstract
Objective To determine the effect of external diaphragm pacemaker (EDP) combined with respiratory biofeedback for pulmonary rehabilitation in tracheotomized patients after stroke. Methods Included in this study were 40 tracheotomized patients after stroke treated in our hospital between January 2015 and June 2016. These patients were randomly assigned to respiratory biofeedback group (n=20) and combined training group (n=20) . All the patients received routine rehabilitation. In addition, the respiratory biofeedback group was subjected to respiratory biofeedback training, and the combined training group was treated with EDP on the basis of respiratory biofeedback training. After 30 days of treatment, the incidence of respiratory infections and the rate of endotracheal tube withdrawal were compared in the two groups. Dyspnea and daily life activities were also evaluated in the two groups and compared with the baseline. Results At 30 days after treatment, the rate of endotracheal tube withdrawal was significantly higher in the combined training group than that in the respiratory biofeedback group[75% (15/20) vs 35% (7/20) , P 0.05) compared with the baseline. On day 30, the combined training group showed significantly improved Barthel index and Borg’s dyspnea score compared with baseline, and also compared with respiratory biofeedback group (all P<0.05) . Conclusion EDP combined with respiratory biofeedback may improve the severity of dyspnea, daily life activities and facilitate withdrawal of endotracheal tube for pulmonary rehabilitation in tracheotomized patients after stroke.
