dc.description.abstractStroke is a leading cause of disability, most commonly with motor deficit. The motor recovery is associated with the structural and/or functional degree of injury to descending motor pathways. Additionally, neuroplasticity contributes to the recovery by unmasking pre-existing connections, establishing new synaptic contacts, reorganizing peri-lesional and contralesional regions. Transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, enhances neuroplasticity. When combined with peripheral therapy, tDCS can enhance motor skill acquisition/consolidation by modulating afferent inputs to the cortex while concurrently receiving central stimulation. Furthermore, meta-analyses showed that bihemispheric stimulation (anodal over affected M1, cathodal over contralesional M1) is better than unihemispheric stimulation, and that higher current density may have a stronger effect. Constraint-Induced Movement Therapy (CIMT) is a standardized, efficacy-proven peripheral rehabilitation therapy to overcome learned non-use of the affected upper extremity. It has two critical components: i)Intense Training of the affected extremity with very specific well-defined interventions; ii)Constraining the unaffected extremity for a certain amount of hours per day. TRANSPORT2, a randomized, double-blinded, multi-centered clinical trial, aims to determine whether there is a treatment effect among three tDCS doses (sham/2mA/4mA) combined with CIMT in 129 patients with first-ever unihemispheric ischemic stroke in the past 30-180 days, resulting in hemiparesis. The primary outcome is the Fugl-Myer Upper-Extremity (FM-UE) scale, a measure of motor impairment, on day 15 after the start of the intervention. Secondary outcomes include i)Wolf-Motor-Function-Test, measure of functional motor activity; ii)Stroke-Impact-Scale, measure of quality of life. We also examine whether the structural and functional integrity of the descending motor tract, measured by MRI(wCST-LL) and TMS(MEPs) are correlated with changes in FM-UE scale, and evaluate their utility as biomarkers of patient selection in future studies. We hypothesize that combination of bihemispheric tDCS at 2 or 4 mA with CIMT will lead to a greater motor improvement on day 15.
