Effectiveness of Transcranial Direct Current Stimulation as an Adjuvant to Aphasia Treatment Following Stroke: Evidence From Systematic Reviews and Meta-Analyses.

Although the tDCS literature is expansive, important questions remain before the technique can be confidently recommended for clinical practice.
