TDCS Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: active TDCS and listening therapyActive Control1 Intervention
TDCS will be administered with NeurConn1 Channel DC-Stimulator Plus (neuroCare Group, München, Germany) according to established guidelines and procedures. The active tDCS will be delivered for 20 minutes at 2mA with a 15-s ramp-up and ramp-down period. Excitatory/anodal tDCS or sham will be administered alongside active listening therapy 5 times a week for 2 weeks.
Group II: sham TDCS and listening therapyPlacebo Group1 Intervention
The sham stimulation will also last for 20 min with 15 sec ramp-up and ramp-down, except the current will be turned down gradually to 0 milliamperes (mA) after 30 seconds. The sham procedure provides the same tingling and itching sensation felt during active tDCS. The sham parameters were chosen based on previous reports that the perceived sensations on the skin, such as tingling, fade out in the first 30 s of tDCS
