Study Arms (3)
10 Hz treatment group
EXPERIMENTALIn active rTMS, 10 Hz stimulations over left DLPFC occurred at a power of 110% of MT for 27-s intervals with 20s inter-train interval. 20 minutes were administered each day (Monday-Friday) for 8 consecutive weeks.
20 Hz treatment group
EXPERIMENTALIn active rTMS, 20 Hz stimulations over left DLPFC occurred at a power of 110% of MT for 20 intervals with 28s inter-train interval. 20 minutes were administered each day (Monday-Friday) for 8 consecutive weeks.
Control Group
SHAM COMPARATORIn sham rTMS, all procedures were identical to 10Hz group except they were the non-magnetized steel cylinders, instead of cylindrical magnets, that were rotated.
Interventions
10 Hz stimulations over left DLPFC occurred at a power of 110% of MT for 27-s intervals with 20s inter-train interval. 20 minutes were administered each day (Monday-Friday) for 8 consecutive weeks.
