PURPOSE
Compare the results in naming tasks of after-stroke aphasic individuals divided into active and placebo groups pre- and post-transcranial direct current stimulation.
METHODS
A double-blind, randomized, controlled study conducted with 14 individuals. Patients underwent five 20-min sessions with stimulation of 2mA's on consecutive days. The cathode was placed over the Broca's homologous area and the anode was placed over the supraorbital region of the left hemisphere. Boston and Snodgrass naming tasks were assessed before and after the stimulation sessions and the results were compared between the groups.
RESULTS
No significant results were observed for sequences 1 and 2 in the Snodgrass test. The Boston test results indicated significant difference related to mean time for correct responses with strategy.
CONCLUSION
The results suggest that simultaneous transcranial direct current stimulation (anodic and cathodic) is a method that can improve the rehabilitation of patients with anomic and Broca's aphasia after stroke, and that language strategies should be considered in the analysis of naming task responses.
目的
比较经颅直流电刺激前后，分为活性组和安慰剂组的中风后失语个体在命名任务中的结果。
方法
对14名个体进行双盲、随机、对照研究。患者连续五天每天接受五次20分钟、2毫安强度的刺激。阴极置于布洛卡区的对应区域，阳极置于左半球眶上区域。在刺激前后评估波士顿命名任务和斯诺德格拉斯命名任务，并比较两组结果。
结果
斯诺德格拉斯测试中序列1和序列2未观察到显著结果。波士顿测试结果表明，在使用策略时正确反应的平均时间存在显著差异。
结论
结果表明，同时经颅直流电刺激（阳极和阴极）是一种可改善中风后命名性失语和布洛卡失语患者康复的方法，并且在分析命名任务反应时应考虑语言策略。
