Motor rehabilitation depends on learning and plasticity, and motor learning can occur after stroke. We tested whether brain stimulation using anodal tDCS added to motor training could improve rehabilitation outcomes in patients after stroke. We performed a randomized, controlled trial in 24 patients at least 6 months after a first unilateral stroke not directly involving the primary motor cortex. Patients received either anodal tDCS (n= 11) or sham treatment (n= 13) paired with daily motor training for 9 days. We observed improvements that persisted for at least 3 months post-intervention after anodal tDCS compared to sham treatment on the Action Research Arm Test (ARAT) and Wolf Motor Function Test (WMFT) but not on the Upper Extremity Fugl-Meyer (UEFM) score. Functional magnetic resonance imaging (MRI) showed increased activity during movement of the affected hand in the ipsilesional motor and premotor cortex in the anodal tDCS group compared to the sham treatment group. Structural MRI revealed intervention-related increases in gray matter volume in cortical areas, including ipsilesional motor and premotor cortex after anodal tDCS but not sham treatment. The addition of ipsilesional anodal tDCS to a 9-day motor training program improved long-term clinical outcomes relative to sham treatment in patients after stroke.","tracks":[{"project":"luoyt2021_800_3","denotations":[{"id":"T1","span":{"begin":94,"end":100},"obj":"DP"},{"id":"T2","span":{"begin":342,"end":348},"obj":"DP"},{"id":"T3","span":{"begin":484,"end":490},"obj":"DP"},{"id":"T4","span":{"begin":1582,"end":1588},"obj":"DP"},{"id":"T5","span":{"begin":583,"end":600},"obj":"DP"}],"attributes":[{"subj":"T1","pred":"source","obj":"luoyt2021_800_3"},{"subj":"T2","pred":"source","obj":"luoyt2021_800_3"},{"subj":"T3","pred":"source","obj":"luoyt2021_800_3"},{"subj":"T4","pred":"source","obj":"luoyt2021_800_3"},{"subj":"T5","pred":"source","obj":"luoyt2021_800_3"}]},{"project":"Linmchun_800_3","denotations":[{"id":"T1","span":{"begin":94,"end":100},"obj":"DP"},{"id":"T2","span":{"begin":1582,"end":1588},"obj":"DP"},{"id":"T3","span":{"begin":342,"end":348},"obj":"DP"},{"id":"T4","span":{"begin":583,"end":600},"obj":"DP"},{"id":"T5","span":{"begin":484,"end":490},"obj":"DP"}],"attributes":[{"subj":"T1","pred":"source","obj":"Linmchun_800_3"},{"subj":"T2","pred":"source","obj":"Linmchun_800_3"},{"subj":"T3","pred":"source","obj":"Linmchun_800_3"},{"subj":"T4","pred":"source","obj":"Linmchun_800_3"},{"subj":"T5","pred":"source","obj":"Linmchun_800_3"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"luoyt2021_800_3","color":"#93b6ec","default":true},{"id":"Linmchun_800_3","color":"#d0ec93"}]}]}}
