ABSTRACT

Objective To evaluate the effect of treating post-stroke dysphagia with biofeedback.Methods PubMed,the Cochrane library,EMbase,the Web of Science,the Chinese biomedical database,the Wanfang database,the China national knowledge infrastructure and the VIP database were searched for reports of randomized and controlled trials (RCTs) of biofeedback for treating post-stroke dysphagia.The search covered the period from each database's inception to December 31,2018.Version 5.3 of the RevMan software was used to analyze the data.Results A total of 17 studies were included,covering 1306 patients.The meta-analysis showed that the intervention group was significantly better than the control group in terms of the total effectiveness rate,the average Functional Oral Intake Scale score,and scores on the Standardized Swallowing Assessment and on the Swallowing Quality-of-Life Questionnaire.The incidence of aspiration pneumonia was also significantly lower in the biofeedback treatment group.Conclusion Biofeedback can be applied to improve swallowing,the level of ingestion and the quality of life of stroke survivors.It can also reduce the incidence of pneumonia.More high-quality RCTs with large samples are needed to further verify these conclusions.
