Therapeutic effect of repetitive transcranial magnetic stimulation in chronic aphasia patients and brain activation patterns

我们对慢性失语症患者每天对右脑Broca‘s同源物进行抑制性重复经颅磁刺激(RTMS)，连续10天。虽然失语症在描述性观察中得到了改善，但标准语言测试显示rTMS治疗后没有明显改善，近红外光谱图获得的偏侧性指数显示，大多数患者在图片命名任务中表现出右侧优势脑激活。RTMS治疗前后偏侧指数变化趋势不一致。

We applied inhibitory repetitive transcranial magnetic stimulation (rTMS) to right-hemisphere Broca's homologue daily, for 10 days in chronic aphasia patients. Although improvement of aphasia was admitted in a descriptive observation, standard language test showed no significant improvement after rTMS treatments, Laterality index, which obtained by near-infrared spectroscopic mapping, revealed most patients demonstrate right dominance brain activation during picture naming task. Then, change in laterality index before and after rTMS treatments did not show uniform trend.
