Transcranial Direct Current Stimulation in Post-Stroke Aphasia Rehabilitation: Bilateral vs Unilateral Online Stimulation

Here we aim to evaluate the efficacy of repeated sessions of transcranial Direct Current Stimulation (tDCS) as additional treatment to standard behavioural rehabilitation in post-stroke aphasic patients comparing bilateral with unilateral left-sided and sham-tDCS. Background: Aphasia is the most common post-stroke cognitive disorder and it severely impacts activities of daily living and social interactions. tDCS recently showed good results in post-stroke aphasia rehabilitiation, even if no agreement at now exists about the stimulation parameters to employ to achieve the best rehabilitative outcome. Design/Methods: We enrolled twenty-two patients with single left-brain lesion at CT or MRI s…
