Previous studies indicated inconsistent results for the treatment effect of repetitive transcranial magnetic stimulation (rTMS) on post-stroke aphasics. The study conducted a meta-analysis to evaluate whether the rTMS with different frequencies demonstrated any effect in patients with post-stroke aphasia. ⋯ In conclusion, we provide preliminary evidence that both LF-rTMS and high-frequency-rTMS might be relatively effective and safe treatment for post-stroke aphasics. However, LF-rTMS mainly plays a short-term role in subacute post-stroke aphasics. Longer-term and large-scale studies are essential to explore the effect of rTMS with different frequencies on post-stroke aphasia.

Review Meta AnalysisSpeech and language therapy for aphasia following stroke.
Aphasia is an acquired language impairment following brain damage which affects some or all language modalities: expression and understanding of speech, reading and writing. Approximately one-third of people who have a stroke experience aphasia. ⋯ This review shows some indication of the effectiveness of SLT for people with aphasia following stroke. We also observed a consistency in the direction of results which favoured intensive SLT over conventional SLT, though significantly more people withdrew from intensive SLT than conventional SLT. SLT facilitated by a therapist-trained and supervised volunteer appears to be as effective as the provision of SLT by a professional. There was insufficient evidence to draw any conclusions in relation to the effectiveness of one SLT approach over another.
