NCT02158312

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.
