目的：考察注意训练对非流畅性失语患者汉字加工任务中双任务范式干扰效应的激活区及偏侧化指数的影响。方法将20例脑卒中后非流畅性失语患者分成实验组及对照组各10例，分别给予注意训练和认知训练，每次30 min，每周5次，共4周。训练前后分别采用组块设计对患者汉字加工任务进行功能磁共振扫描，比较训练前后双任务范式干扰效应的激活区及偏侧化指数。结果训练前两组患者均为右侧额下回、双侧顶叶、双侧小脑显著激活；训练后，实验组各激活区更加显著，而对照组各激活区未见显著变化；训练前两组患者均呈右半球优势；训练后实验组呈左半球优势，而对照组仍呈右半球优势。结论在双任务范式干扰效应中，右侧额下回、双侧顶叶、双侧小脑可能在知觉注意阶段对解决双重任务干扰非常重要；注意训练后激活更加显著；注意训练可能使失语症患者语义加工产生了功能重组。
目的：攷察註意訓練對非流暢性失語患者漢字加工任務中雙任務範式榦擾效應的激活區及偏側化指數的影響。方法將20例腦卒中後非流暢性失語患者分成實驗組及對照組各10例，分彆給予註意訓練和認知訓練，每次30 min，每週5次，共4週。訓練前後分彆採用組塊設計對患者漢字加工任務進行功能磁共振掃描，比較訓練前後雙任務範式榦擾效應的激活區及偏側化指數。結果訓練前兩組患者均為右側額下迴、雙側頂葉、雙側小腦顯著激活；訓練後，實驗組各激活區更加顯著，而對照組各激活區未見顯著變化；訓練前兩組患者均呈右半毬優勢；訓練後實驗組呈左半毬優勢，而對照組仍呈右半毬優勢。結論在雙任務範式榦擾效應中，右側額下迴、雙側頂葉、雙側小腦可能在知覺註意階段對解決雙重任務榦擾非常重要；註意訓練後激活更加顯著；註意訓練可能使失語癥患者語義加工產生瞭功能重組。

Objective To investigate the effect of attention training on cortical activation area and lateralization index in interference ef-fect of dual-task paradigm as the poststroke nonfluent aphasiacs processing the Chinese character tasks. Methods 20 cases with nonfluent aphasia after stroke were divided into the training group and the control group, who accepted attention training and cognitive training respec-tively, 30 min a time, 5 times a week, for 4 weeks. They were investigated the cortical activation area and lateralization index caused by in-terference effect of dual-task paradigm under block design. Results The right inferior frontal gyrus, bilateral parietal and cerebellar cortex were activated before training in both groups, and more activated after attention training, but no change after cognitive training. Lateraliza-tion index suggested that the right brain was more activated before training, while the left side was activated after attention training, but no change after cognitive training. Conclusion The right inferior frontal gyrus, bilateral parietal and cerebellar cortex are very important in solv-ing the dual task interference in the attention stage, and they are activated after attention training. It indicates that attention training makes a significant functional reorganization on Chinese character processing in poststroke nonfluent aphasiacs.
