AbstractBackground: Unilateral application of repetitive magnetic stimulation has been approved to be effective for post-stroke aphasia either through ipsilesional cortical facilitation in the dominant hemisphere or the contralateral suppression over the non-dominant hemisphere in western countries.
However, the clinical outcome of the application of bilateral stimulation is still unknown in Mandarin users. We aimed to see whether the bilateral sequential application of different patterns of theta burst stimulation is able to improve the language function in subacute aphasic patients.
Methodology: A pilot study of two subacute stroke cases was conducted. They were received the bilateral sequential TBS (continuous TBS over right Broca’s homologue followed by intermittent TBS over the Broca’s area, localized by 10-20 electroencephalogram system) daily, over and totally 10 sessions. Mandarin version of Western Aphasia Battery was applied before and after the whole stimulation procedure.
Results: The intervention appeared to improve their sematic fluency and naming performance mostly.
Conclusion: This setting with relatively simple localization method and relatively short treatment time is suitable for clinical purpose in East-Asian population. More controlled cases should be included in further researches to test whether this bilateral application is better than the unilateral application, as well as the effect of conventional speech therapy and the spontaneous recovery of language function.
