Functional Assessment of Diaphragm Muscle in Stroke Patients and Research of Rehabilitation Intervention
Abstract
Objective:To evaluate the diaphragm function of stroke patients and investigate the effect of an external diaphragm pacemaker(EDP)on post-stroke respiratory function.Methods:Included in this study were twenty patients after stroke in Rehabilitation Department of Nanjing Jiangning Hospital during December 2017 to March 2018, and they were selected as the experimental group. Twenty healthy volunteers as the control group matched with the gender and age. Stroke patients in the experimental group were enrolled for two weeks of external diaphragmatic pacing treatment. Before and after two weeks of treatment, both groups were evaluated using the mean values of normal for thick and motion of the right hemidiaphragms during quiet breathing and deep breathing, pulmonary function tests, including forced vital capacity(FVC)and forced expiratory volume in one second(FEV1), arterial blood gas analysis(arterial partial pressure of oxygen PaO2, oxygenation index, partial pressure of carbon dioxide PaCO2, pH value)and a fatigue severity scale(FSS).Results:The ratio of diaphragm thickness, diaphragm displacement, forced vital capacity, FEV1, FEV1/FVC, oxygen and index, and SaO2in the experimental group were significantly lower than those of the control group, pH value and fatigue index in the experimental group were significantly higher than those of the control group. The diaphragm muscle thickness ratio, diaphragmatic displacement, forced vital capacity, the FEV1, FEV1/FVC, oxygen and index, and SaO2were significantly higher after EDP, and the pH value and fatigue index were lower after EDP, and all had statistically significant differences.Conclusion:Diaphragm function and lung function are significantly reduced after stroke, and external diaphragm pacemaker treatment plays a role in helping to improve respiratory function and relieve fatigue after stroke.
