Objective  To evaluate the systematic reviews of repetitive transcranial magnetic stimulation (rTMS) for insomnia, to provide supporting evidence for clinical practice. Methods  PubMed, Embase, Web of Science, Cochrane Library, Elsevier Science Direct, China National Knowledge Infrastructure, SinoMed, Wanfang and Chongqing VIP were searched from databases establishment to May 30, 2022, to find systematic reviews on the treatment of insomnia with rTMS as the main method. The methodological quality, reporting quality and evidence quality of outcome indicators were evaluated by AMSTAR 2, PRISMA 2020 and GRADE. Results  A total of 4 systematic reviews published between 2018 and 2021 were included. Further analysis showed that one of the systematic reviews had a low AMSTAR 2 quality rating and the remaining systematic reviews were very low. The average PRISMA 2020 score of these 4 systematic reviews was (20.75±3.27) points, of which 3 systematic reviews had some defects in their reports, and the other one had relatively complete reports. The GRADE evidence quality assessment showed that there were 40 outcome indicators in the included literature, of which 3 outcome indicators (sleep quality, the percentage of S2 sleep in total sleep time, and S3 sleep in percentage of total sleep time) were rated as moderate, 17 were rated as low and 20 were rated as very low. Conclusions  The treatment of insomnia by rTMS has achieved certain effects in clinical practice, but the systematic review of rTMS as the main intervention measure for insomnia needs to further improve the quality and standardize related research. The clinical application of rTMS for insomnia should be treated as appropriate.
