Background: Post-stroke dysphagia (PSD) is a common complication with a high incidence rate, significantly impairing patients' quality of life and health. Although conventional swallowing training is widely used, its efficacy depends on interindividual heterogeneity. Surface electromyographic biofeedback (sEMG-BF) is an emerging rehabilitation technology that shows promising potential in improving swallowing function. However, there is a lack of systematic and comprehensive evaluation and high-quality evidence to support its clinical application. Objective: This study aims to systematically evaluate and conduct a network meta-analysis comparing the efficacy of sEMG-BF, NMES, and conventional therapy in improving electrophysiological outcomes, swallowing function, and quality of life for patients with PSD. Methods: A systematic review and network meta-analysis were conducted by searching databases, including PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus for prospective randomized controlled trials on the application of sEMG-BF in patients with PSD. We included randomized controlled trials that compared sEMG-BF, NMES, or conventional therapy in patients with PSD. The study focused on the effects of sEMG-BF on electrophysiological outcomes in these patients. Results: Six studies were included in the analysis. sEMG-BF was found to significantly increase mean amplitude (MD = 6.45, 95% CI: 3.53, 9.38) and reduce swallowing duration (MD = -0.22, 95% CI: -0.26, -0.18)....
