High-definition Transcranial Electrical Stimulation for Upper Extremity Rehabilitation

The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms. HD-tCES will be applied for 20 minutes at an intensity of 1.0 mA direct current stimulation and a specific-added waveform each time, 3 times a week, lasting for 4 weeks.

The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms. Sham HD-tCES will consist of a 5-second ramp up to 1.0 mA direct current stimulation and a specific-added waveform followed immediately by a 5-second ramp down, no current in the middle 19 minutes 40 seconds, and a ramp-up and ramp-down period during the last 10 seconds.

Upper extremity rehabilitation programs will be selected and graded in accordance with each patient's upper extremity function and specific aims of activities of daily living. Upper extremity rehabilitation will be provided for 30 minutes each time, 3 times a week, lasting for 4 weeks.
