Research Abstract

Background. Recent neuroimaging studies on poststroke aphasia revealed maladaptive cortical changes in both hemispheres,
yet their functional contribution in language recovery remains elusive. The aim of this study was to evaluate the long-term
efficacy of dual-hemisphere repetitive transcranial magnetic stimulation (rTMS) on poststroke aphasia. Methods. Thirty
patients with subacute poststroke nonfluent aphasia were randomly allocated to receive real or sham rTMS. Each patient
received 1000 rTMS pulses (1 Hz at 110% of resting motor threshold [rMT] over the right unaffected Broca’s area and 1000
pulses (20 Hz at 80% rMT) over the left affected Broca’s area for 10 consecutive days followed by speech/language training.
The language section of the Hemispheric Stroke Scale (HSS), the Stroke Aphasic Depression Questionnaire–Hospital
Version (SADQ-H), and the National Institutes of Health Stroke Scale (NIHSS) were measured before, immediately after
the 10 sessions, and 1 and 2 months after the last session. Results. At baseline, there were no significant differences
between groups in demographic and clinical rating scales. However, there was a significantly greater improvement in the
HSS language score as well as in the SADQ-H after real rTMS compared with sham rTMS, which remained significant
2 months after the end of the treatment sessions. Conclusion. This is the first clinical study of dual-hemisphere rTMS in
poststroke aphasia. Combining dual-hemisphere rTMS with language training might be a feasible treatment for nonfluent
aphasia; further multicenter studies are needed to confirm this result.
