Abstract:
Objective:To document any effect of combining respiratory-muscle resistance training with feedback respiratory electrical stimulation in rehabilitating the diaphragm function and lung function of stroke survivors.Methods:Sixty hemiplegic stroke survivors were randomly assigned to an observation group or a control group, each of 30. Both groups were given conventional rehabilitation, including respiratory-muscle resistance training. The observation group additionally received feedback respiratory electrical stimulation twice a day, six days a week for 3 weeks. Before and after the treatment, ultrasound was used to measure the end-inspiratory and end-expiratory thickness of the diaphragm. Diaphragm movement during quiet breathing and deep breathing was also observed, and the diaphragm thickening fraction was calculated. The incidence of diaphragm dysfunction on the affected and healthy sides of the two groups before and after the treatment was also analyzed and compared.Results:Diaphragm dysfunction on either side had decreased significantly more in the observation group than in the control group after the treatment. The observation group also showed significantly greater average improvement in the thickening functions and in diaphragm movement on both the affected and healthy sides during quiet breathing and deep breathing. All of the pulmonary function indicators improved significantly in both groups after the treatment, but those of the observation group were, on average, significantly better than the control group′s averages.Conclusions:Combining 3 weeks of respiratory muscle resistance training with electrical stimulation feedback can effectively increase the bilateral thickness of the diaphragm and diaphragm movement in deep breathing of hemiplegic stroke survivors. That reduces the incidence of diaphragm dysfunction.
