Research Abstract

In this study, we researched the method of transcranial magnetic stimulation and transcranial direct current stimulation for the purpose of the language function improvement in aphasia. The inhibitory stimulation to the right Broca region of the nonfluent aphasia patients significantly hastened naming rapidity, and the excitability stimulation to the supplementary motor area of the nonfluent aphasia patients was able to significantly delay speech reaction time. The inhibitory stimulus to the right Broca region produced significant improvement for a language function.
