ObjectiveTo systematically evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on post-stroke depression (PSD).MethodsWe searched databases including the PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Internet, Wanfang, China Biology Medicine database and VIP database to collect randomized controlled trials comparing the effect of the rTMS group and the control group with the scores of depression scale from January 2013 to April 2018. Patients in the rTMS group received rTMS plus drug therapy or conventional treatment for PSD, and patients in the control group received rTMS sham stimulation or not, but the drug treatment or routine treatment was required. When the quality evaluation and data extraction were carried out by two reviewers independently, the Meta-analysis was performed using RevMan 5.3 software and Stata 14.0 software.ResultsA total of 18 literatures involving 1 376 patients (687 patients in the rTMS group and 689 patients in the control group) with PSD were included in this Meta-analysis. Compared with the control group, the rTMS group could effectively reduce the depression scores of PSD patients [standard mean difference (SMD)=–1.13, 95% confidence interval (CI) (–1.42, –0.84), P<0.000 01], and the effective rate of rTMS was 91.7%; meanwhile, rTMS could promote the scores of the National Institute of Health Stroke Scale and the activities of daily living of patients with PSD [SMD=–1.00, 95%CI (–1.25, –0.75), P<0.000 01;SMD=1.56, 95%CI (0.80, 2.32), P<0.000 01]. The source of heterogeneity was not found according to subgroup analysis and Meta-regression analysis. Additionally, few studies reported adverse reactions after the treatment of rTMS.ConclusionsrTMS has a positive effect on depression, neurological deficits, and decreased ability of daily living in patients with PSD. Due to the quality of the included studies, the conclusions need to be verified further.
