Transcranial Electrical Stimulation With Special Waveform for Upper Extremity Rehabilitation for Patients With Stroke

The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms. tCES will be applied for 20 minutes at an intensity of 1.0 -1.5 mA direct current stimulation and a specific-added waveform each time, 3 times a week, lasting for 6 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 tCES will consist of a 5-second ramp up to 1.0-1.5 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.
