Abstract

BACKGROUND: Rehabilitation of patients with post-stroke aphasia is an important medical and social goal. The use of traditional methods of rehabilitation is often not effective enough, which forces us to look for new methods aimed at restoring lost functions. AIM: The aim of this study is to determine the effectiveness of non-invasive brain stimulation using transcranial direct electric current stimulation (tDCS) in patients with post-stroke aphasia. MATERIALS AND METHODS: 28 patients with motor post-stroke aphasia were examined according to the method of L.S. Tsvetkova with co-authors. All patients received a traditional rehabilitation complex: psychological and correctional classes with a speech therapist-aphasiologist; neurometabolic therapy. 14 patients (Group I) additionally had transcranial direct electric current stimulation; 14 patients had placebo transcranial direct electric current stimulation. RESULTS: All patients with post-stroke aphasia showed an improvement in expressive and impressive speech, however, in patients who had true transcranial direct electric current stimulation, the improvement in expressive and impressive speech was higher than in patients who had placebo transcranial direct electric current stimulation. There were no complications from the use of transcranial direct electric current stimulation. CONCLUSION: Based on the results of the study, it can be concluded that it is expedient to include the non-invasive transcranial direct electric current stimulation method in the rehabilitation of patients with post-stroke aphasia.
经颅直流电刺激(tDCS)对脑卒中后失语患者康复的影响
背景:脑卒中后失语患者的康复是一个重要的医学和社会目标。使用传统的康复方法往往不够有效,这迫使我们寻找旨在恢复失去的功能的新方法。目的:本研究的目的是确定经颅直流电刺激(tDCS)非侵入性脑刺激对脑卒中后失语患者的有效性。材料与方法:28例脑卒中后运动性失语症患者按照L.S. Tsvetkova等人的方法进行检查。所有患者都接受了传统的康复治疗:由语言治疗师-失语症学家进行心理和矫正课程;neurometabolic疗法。14例患者(I组)加行经颅直流电刺激;14例患者采用安慰剂经颅直流电刺激。结果:所有脑卒中后失语症患者在表达性和印象性言语方面均有改善,但在真正经颅直流电刺激的患者中,表达性和印象性言语的改善高于安慰剂经颅直流电刺激的患者。经颅直流电刺激无并发症。结论:基于本研究结果,无创经颅直流电刺激法在脑卒中后失语患者康复治疗中是适宜的。
