目的：探讨经颅直流电刺激(tDCS)对脑卒中后失语症恢复的影响。方法选取2012年4月~2013年1月本科脑卒中失语症患者20例。采用A-B设计，A期行tDCS假刺激+语言治疗10次(每周5次)，B期为阳极tDCS+语言治疗10次(每周5次)，共4周。B期给予左侧Broca或Wernicke区阳极tDCS刺激。在A期、B期前后进行治疗项和非治疗项图命名评价。结果 B期治疗项和非治疗项图命名评分差值高于A期(t>3.030, P<0.05)。结论 tDCS能够改善脑卒中失语症患者图命名的准确率。%Objective To investigate the effect of transcranial direct current stimulation (tDCS) on aphasia recovery after stroke. Meth-ods From April, 2012 to January, 2013, 20 aphasic patients after stroke were enrolled in an A-B experiment design. During phase A, ten times of sham tDCS and language training (five days a week) were implemented, then ten times language training combined with tDCS (five days a week) were implemented in phase B. The treatment lasted for four weeks. Picture naming was measured for all patients before and af-ter treatment both in phase A and phase B. Results The D-value scores of picture naming before and after treatment were significantly more in phase B than in phase A in both treatment items and non-treatment items (t>3.030, P<0.05). Conclusion tDCS could raise the accuracy of picture naming in patients with aphasia after stroke.
