Effects of different frequencies of repetitive transcranial magnetic stimulation in stroke patients with non-fluent aphasia: a randomized, sham-controlled study
2018
ABSTRACT Objective: The purpose of this study was to compare the efficacy of repetitive transcranial magnetic stimulation (rTMS) applied at different frequencies to the contra-lesional hemisphere to optimize the treatment of post-stroke non-fluent aphasia. Method: Patients with post-stroke non-fluent aphasia were divided randomly into four groups: a high-frequency rTMS (HF-rTMS) group (10 Hz), a low-frequency rTMS (LF-rTMS) group (1 Hz), a sham stimulation group, and a control group. All groups received the standard treatment (consisting of drug therapy, conventional physical exercises, and speech training); in the HF-rTMS and LF-rTMS, this was supplemented with magnetic stimulation that targeted the mirror area within the right hemispheric Broca’s area. Patients’ language ability was assessed prior to, immediately after, and at 2 months post-treatment by the Chinese version of the Western Aphasia Battery (WAB). Results: When measured immediately post-treatment, as well as at 2 months post-treatment, the ...
