Transcranial Direct Current Stimulation Post-Stroke Upper Extremity Motor Recovery Studies Exhibit a Dose-Response Relationship

• Transcranial direct current stimulation (tDCS) shows dose-dependent effect in post-stroke motor recovery.• Meta-analysis of 8 studies that administered ≥5 sessions of tDCS therapy and used Fugl-Meyer Upper Extremity scale (FM-UE) as an outcome measure shows that tDCS offers a large post-stroke motor recovery effect size in subjects with chronic stroke when compared with acute stroke.• Bihemispheric montage with anode on ipsilesional side and cathode on contralesional side also seems to offer a large effect size in post-stroke motor recovery.
