Establishing a Prognostic Model for Stroke Recovery

A trained research staff or physician will perform tDCS to the subject. Direct current will be delivered by a battery-operated, constant current stimulator, through 2 rubber electrodes embedded in a pair of saline-soaked sponge bag. Stimulation intensity will be ramped up to 1 mA over 30 seconds and maintain at 1 mA for 20 minutes, and then ramped down to 0 mA over 30 seconds.
