Low-frequency repetitive transcranial magnetic stimulation to the right Broca mirror area for improving auditory comprehension in a sensory aphasia after stroke: a case report

Abstract

Aphasia is a common consequence of stroke and repetitive transcranial magnetic stimulation (rTMS) may be a promising brain stimulation technique in the treatment of aphasia. However, there are few reports about the therapeutic effect of rTMS for Broca’s area in patients with sensory aphasia. This study reported one stroke patient with sensory aphasia who received 6 treatment sessions of low-frequency rTMS before speech and language therapy. The target area was the Broca mirror area in the right hemisphere. After treatment, the auditory comprehension of the patient improved from 46 to 112, the naming improved from 18 to 32, and the AQ improved from 34.2 to 42.6. However, the level of functional language, spontaneous speech and repetition did not show obvious improvement.
