Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
HD-tDCS group
Constant current (1mA) will be applied for 20min and the anode will be placed over the defined target area
HD-tDCS group
5 sintered Ag/AgCl ring electrodes will be used at a radius of \~5cm. The electrodes will be placed inside plastic electrode holders which will be filled with gel to have better contact with the scalp.
Conventional tDCS group
Constant current (1mA) will be applied for 20min and the anode will be placed over the standard C3/C4 position
Conventional tDCS group
A pair of 25 cm2 rubber electrodes enclosed in saline-soaked sponges and affixed to the head with rubber bands.
Sham HD-tDCS group
The stimulator will be shut down after 30s of stimulation. The patients will feel the initial itching sensation at the beginning in order to evaluate the placebo effect.
Sham HD-tDCS group
A pair of 25 cm2 rubber electrodes enclosed in saline-soaked sponges and affixed to the head with rubber bands.
