An Exploratory Preliminary Study on the Effect of Combined Transcranial Photobiomodulation(tPBM)-Transauricular Vagus Nerve Stimulation(taVNS) on Alcohol Craving and Neurophysiological Marker in Drinkers (in South Korea)

"Stimulation Program (5 Weeks) Each participant will follow one of the following programs, assigned randomly, five days a week for a total duration of five weeks.~tPBM Group: Participants will receive transcranial photobiomodulation (tPBM) for 15 minutes per day.~taVNS Group: Participants will receive transcutaneous auricular vagus nerve stimulation (taVNS) for 15 minutes per day.~Combined Treatment Group: Participants will simultaneously receive both tPBM and taVNS for 15 minutes per day."
