Abstract

ObjectiveTo evaluate the effect of non-invasive brain stimulation (NIBS) in improving limb motor dysfunction and daily living activity during at the phase of acute stroke. Materials and MethodsRandomized controlled trials about the effect of NIBS on hemiparesis in acute stroke were retrieved from databases of China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Data, CBM, PubMed, Embase, Cochrane Library, and Web of Science from inception until January 3rd 2022. The quality of the trials was assessed, and the data were extracted according to the Cochrane Handbook for Systematic Reviews of Interventions. A statistical analysis was carried out using Review Manager 5.3 and STATA 14. The effect size was evaluated by using the weighed mean difference (WMD) and a 95% confidence interval (CI). The stability and sensitivity of the results and sources of heterogeneity were also analyzed. Results12 studies involving 639 patients were included. Our meta-analysis showed that NIBS could improve the Fugl-Meyer Assessment (weighed mean difference = 3.96, 95% confidence interval = 3.45 to 4.48) and Barthel Index (weighed mean difference = 12.29, 95% confidence interval = 4.93 to 19.66), while reducing the National Institutes of Health Stroke Scale (weighed mean difference = −2.37, 95% confidence interval = −3.43 to −1.31). ConclusionNIBS is effective in improving paretic limb motor function and activities of daily living in patients during at the phase of acute stroke.
