Objective To systematically review the efficacy of three transcranial direct current stimulation protocols (anodal stimulation, cathodal stimulation, and bipolar stimulation) on upper extremity function interventions in stroke patients. Methods PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, CBM, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of three transcranial direct current stimulation protocols on upper extremity function interventions in stroke patients from inception to April 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, the network meta-analysis was performed by using R software and ADDIS software. Results A total of 64 RCTs involving 3 968 patients were included. The results of network meta-analysis showed that, the probability order of the three stimulation methods on FMA-U, MBI, NIHSS score was: anode>bipolar>cathode>control. In addition, the probability order on ARAT and BBT score was: anode>cathode>bipolar>control. Conclusion Current evidence shows that the intervention effect of anodic stimulation on upper limb function of stroke patients may be better. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusion.
