IRCT20171128037666N3 IRCT 2020-04-06 Bagheiat-allah University of Medical Sciences the comparison of novel electrical cranial stimulation by TDCS in the management of stress. The effect of novel stimulation waveform of the cranial stimulation on the biochemical and electrophysiological markers of acute psychosocial stress. 2020-04-04 anticipated 45 Complete https://irct.ir/trial/41220 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: Subjects are randomly assigned into three groups for post-stress intervention. How to group people into groups is randomized by using the website www.graphpad.com, Blinding description: The brain stimulator is put on everyone's head and they are not notified if the device is on or off. N/A Acute social stress. Intervention 1: Intervention group: brain stimulation TDCS: subjects are exposed to 10 minutes of TDCS current with the electrode size : 7 * 5 cm, 2 intensity of 1 mA, DC constant current and anode placed on the right side of the medial frontal cortex between the channel (FPZ-F2) and the cathode electrode placed on the head Center (O2-P4). Intervention 2: Control group: placebo brain stimulation TDCS: size and place the electrodes like above intervention but the electric current is not established. Intervention 3: Intervention group: bioelectrical brain stimulation:size and place the electrodes like above intervention but the induced current is the recorded EEG that saved before with amplitude and duration of TDCS. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is University disagreement
