Abstract
BACKGROUND: A lot of research on the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in patients with aphasia in the chronic stage deals with low-frequency stimulation, and reports on high-frequency stimulation (HF-rTMS) are scarce. OBJECTIVE: The purpose of this study was to evaluate retrospectively the effectiveness of high-frequency rTMS in combination with intensive speech-language-hearing therapy (ST) following the identification of the stimulation site using functional magnetic resonance imaging (fMRI) before, after the procedure and at 3 months in patients with aphasia in the chronic stage. METHODS: 20 patients with aphasia in the chronic stage who met the eligibility criteria for rTMS therapy and who underwent HF-rTMS for the first time were included in the present study. All patients received fMRI before hospitalization, and the stimulation site was decided accordingly. RESULTS: There was a significant improvement in all patients, rTMS to the left hemisphere, fluent and non-fluent groups by the evaluation of pre- and post- treatment by hospitalization. All groups had a significant improvement in total Standard Language Test of Aphasia score at 3 months when compared with the time of hospitalization. CONCLUSIONS: The current study indicates that HF-rTMS in combination with intensive ST is an effective therapeutic approach for patients with aphasia in the chronic stage.
