Abstract

We systematically reviewed the literature on neural changes following anomia treatment post-stroke. We conducted electronic searches of CINAHL, Cochrane Trials, Embase, Ovid MEDLINE, MEDLINE-in-Process and PsycINFO databases; two independent raters assessed all abstracts and full texts. Accepted studies reported original data on adults with post-stroke aphasia, who received behavioural treatment for anomia, and magnetic resonance brain imaging (MRI) pre- and post-treatment. Search results yielded 2481 citations; 33 studies were accepted. Most studies employed functional MRI and the quality of reporting neuroimaging methodology was variable, particularly for pre-processing steps and statistical analyses. The most methodologically robust data were synthesized, focusing on pre- versus post-treatment contrasts. Studies more commonly reported increases (versus decreases) in activation following naming therapy, primarily in the left supramarginal gyrus, and left/bilateral precunei. Our findings highlight the methodological heterogeneity across MRI studies, and the paucity of robust evidence demonstrating direct links between brain and behaviour in anomia rehabilitation.

卒中后失语症失范治疗后治疗诱导的神经可塑性:神经影像学研究的系统综述。
我们系统地回顾了脑卒中后失范治疗后神经变化的文献。我们对CINAHL、Cochrane试验、Embase、Ovid MEDLINE、MEDLINE in Process和PsycINFO数据库进行了电子搜索;两名独立的评分员对所有摘要和全文进行了评估。公认的研究报告了关于中风后失语症的成年人的原始数据,他们接受了行为异常治疗,以及治疗前后的核磁共振脑成像(MRI)。搜索结果产生2481次引用;接受了33项研究。大多数研究采用了功能性MRI,神经成像方法的报告质量各不相同,尤其是在预处理步骤和统计分析方面。综合了方法学上最稳健的数据,重点是治疗前与治疗后的对比。更常见的研究报告称,命名治疗后激活增加(相对于减少),主要发生在左侧缘上回和左侧/双侧楔前。我们的研究结果强调了MRI研究的方法学异质性,以及缺乏强有力的证据证明大脑和失范康复行为之间存在直接联系。
