Objective: To compare the clinical efficacy of repetitive transcranial magnetic stimulation (rTMS) under facial feature point (FFP) localization versus neuro-navigated localization for depression.
Methods: 42 depressed patients were randomly assigned to two groups, received 10 Hz rTMS twice daily for 10 consecutive days. Relevant symptom scale assessments were conducted by professionals at baseline, after 10 sessions, and at the end of treatment. The confidence interval was calculated at a 95 % confidence level. The significant level was set at p < 0.05.
Results: The absolute change in Hamilton Rating Scale for Depression (HAMD) total score from baseline to the end of therapy did not differ significantly between the groups. The generalized estimating equation showed the main effect of time was significant, which showed improvement of depressive symptoms in patients throughout treatment. Upon completion of the treatment, FFP group showed a response rate of 64.7 % and a remission rate of 29.4 %, whereas the navigated group exhibited a response rate of 61.1 % and a remission rate of 44.4 %. There was no serious adverse events occurred during the treatment process. Throughout the study, no intervention was made on the normal medication treatment, and some patients had concomitant antidepressants and benzodiazepines.
Conclusion: There was no significant difference in clinical efficacy between FFP localization and navigated localization in the small-sample study. However, due to the limited sample size and lack of rigorous non-inferiority testing, the superiority of one over the other remains uncertain, necessitating rigorous experimental design to validate the efficacy difference between the two localization methods.
