Brief Summary
Post-stroke sensorimotor recovery largely depends on ipsilesional and interhemispheric motor circuit reorganization. Transcranial direct current stimulation (tDCS) may be used to enhance after-effects of rehabilitation through membrane polarization modulation. In this double-blind, crossover randomized controlled trial, we aim to investigate whether single-session, bihemispheric tDCS to the primary motor cortex (M1) in combination with upper extremity rehabilitation therapy modulates ipsilesional motor circuit excitability using transcranial magnetic stimulation (TMS) and magnetoencephalography (MEG) measures.

Eligibility Criteria
You may qualify if:
- subacute (2-4 weeks after stroke onset) patients

You may not qualify if:
- cerebral cortex lesions
- containing metal implants (such as implanted electrodes, pacemakers)
- sensitive or fear of electromagnetic waves
- pregnant women
- history of alcohol or drug abuse
- history of seizures or epilepsy EEG recording
- other significant disease or neuropsychiatric disorders
- claustrophobia
- fixed dentures over two or more (enough to interfere with MEG signals)
