Fifty-six patients diagnosed with a moderate to severe depressive episode received 15 daily treatments of either rTMS ( 110 % motor-threshold ; rightDLPFC , 1000 stimuli at 1 Hz + leftDLPFC , 1000 stimuli at 10 Hz ) , theta-burst stimulation ( 80 % motor-threshold ; rightDLPFC , continuous TBS , 1200 stimuli + leftDLPFC , intermittent TBS , 1200 stimuli ) , or sham TMS ( N = 17 , sham coil with the TBS protocol ) .
