Objective: The present study aimed to evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) at a high frequency using a miniaturized device compared to standard rTMS and sham rTMS for the treatment of de-pression. Methods: Fifty-four patients with depression were randomly assigned to either 15 days of miniaturized, standard, or sham rTMS. The stimulation consisted of 60 trains of 5 seconds at 10 Hz for 30 minutes. Clinical measures were assessed at baseline and on the final day of the stimulation. Results: A repeated-measures analysis of variance revealed a significant main effect of time and a time by group inter-action on Hamilton Rating Scale for Depression scores. There were no significant correlations between individual motor thresholds and changes of clinical outcomes. Our results revealed a significant reduction in the Hamilton Rating Scale for Depression in the miniaturized and standard groups compared to the sham group. Conclusion: The antidepressant utility of miniaturized rTMS using subthreshold stimulation was comparable to that of standard stimulation.
