Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Anode HD-tDCS
The center anode is fixed on the ipsilesional primary motor cortex and the 4 surrounding cathode electrodes will be placed about 6 cm to the center.
HD-tDCS
Different stimulation protocols will be applied to the primary motor cortex of stroke patients. After 20-minute stimulation, EMG-driven robot hand training will be conducted.
Cathode HD-tDCS
The center cathode is fixed on the contralesional primary motor cortex and the 4 surrounding anode electrodes will be placed about 6 cm to the center.
HD-tDCS
Different stimulation protocols will be applied to the primary motor cortex of stroke patients. After 20-minute stimulation, EMG-driven robot hand training will be conducted.
Sham HD-tDCS
The center anode is fixed on the ipsilesional primary motor cortex and the 4 surrounding cathode electrodes will be placed about 6 cm to the center.
HD-tDCS
