Abstract:
ObjectiveTo evaluate the effects of transcranial direct current stimulation (tDCS) on post-stroke aphasia (PSA). MethodsLiteratures about tDCS for PSA were retrieved from PubMed, Web of Science, Cochrane library, Embase CNKI and Wanfang Data, until December, 2021. The contents of the author, publication time, subjects, intervention methods and time, main outcome indicators and conclusions were extracted. ResultsA total of 1 026 articles were returned and 45 articles were finally included. The publication time was from 2010 to 2021. The subjects of the study were patients with PSA. The main outcome indicators were the various speech scales and their sub-items. For most of the trials, scores of the scales were better in the experimental groups than in the control groups after treatment, and a few found little improvement in Boston Diagnostic Aphasia Examination, or only improved in complex language tasks. tDCS can improve the repetition, naming, spelling and verbal fluency of PSA patients, which might relate with electrode placement, current magnitude, duration, intensity and left cortical integrity. ConclusiontDCS is effective on different language sub-items of PSA, and various with the program of tDCS.
