AbstractThe objective was to synthesize results from studies that assessed symptom relief after repetitive transcranial magnetic stimulation (rTMS) treatment for post‐traumatic stress disorder (PTSD) and investigate the long‐term effectiveness of rTMS for treating PTSD. We searched multiple databases for relevant randomized controlled trials of rTMS for PTSD treatment up to 1 January 2023. Two researchers evaluated the studies and focused on the CAPS and PCL as outcome indicators. We used STATA17 SE software for the data analysis. Eight articles involving 309 PTSD patients were analysed in a meta‐analysis, which found that rTMS had a significant and large effect on reducing core post‐traumatic symptoms [Hedges'g = 1.75, 95% CI (1.18, 2.33)]. Both low and high‐frequency rTMS also significantly reduced symptoms, with the latter having a greater effect. rTMS was shown to have a long‐term effect on PTSD, with all three subgroup analyses demonstrating significant results. Interestingly, no significant difference in symptom relief was found between the follow‐up and completion of treatments [Hedges'g = 0.01, 95% CI (−0.30, 0.33)], suggesting that the treatment effect of rTMS is stable. The meta‐analysis provides strong evidence that rTMS is effective in reducing the severity and symptoms of PTSD in patients, and follow‐up studies confirm its long‐term stability.
