ABSTRACT
Objective:To study the effect of transcranial direct current stimulation (tDCS) regulating excitability of the vagus nerve on dysphagia after stroke. Methods:From September, 2020 to February, 2021, 28 patients with dysphagia after stroke were randomly divided into control group (n = 14) and tDCS group (n = 14). Both groups accepted swallowing function training, and tDCS group received anodal tDCS over vagus nerve, while the control group received sham tDCS. They were assessed with modified Mann Assessment of Swallowing Ability (MMASA) and Australian Therapy Outcome Measures (AusTOMs)-swallowing scale before and after treatment. Results:The scores of MMASA (|t| > 5.593, P < 0.001) and AusTOMs swallowing scale (|Z| > 2.121, P < 0.05) increased in both groups after treatment, and were higher in tDCS group than in the control group (|t| = 2.439, |Z| = 2.079, P < 0.05). Conclusion:Anodal tDCS over vagus nerve may further release dysphagia after stroke.
ABSTRACT
Objective To investigate the effect of respiratory training on sleep breathing parameters in cerebral infarction patients complicated with obstructive sleep apnea syndrome(OSAS). Methods From March 1st,2016 to August 30th,2017,60 young and middle-aged patients with cerebral infarction in bas-al ganglia complicated with OSAS in Wenzhou Hospital were divided into control group and respiratory training group with 30 cases in each group.All subjects underwent clinical data registration,and received conventional treatment and rehabilitation.The respiratory training group accepted manual respiratory training in addition,once a day,five times a week,for eight weeks.Before and after treatment,they were monitored to access apnea-hypop-nea index(AHI),maximum oral pressure,average oxyhemoglobin saturation(SaO2),the lowest SaO2,the oxygen desaturation index,duration of lowest SaO2,and time percentages of SaO2<90% and<80%. Results After treatment,the AHI,the maximum oral pressure,the average SaO2,the lowest SaO2and the time percentage of SaO2<90% were better in the respiratory training group than in the control group(t>3.086,P<0.01). Conclusion Respiratory training could improve the respiratory function, reduce the airway resistance, and relieve the nocturnal sleep apnea symptom. It may be one of the rehabilitation methods for brain injury complicated with OSAS.
