The effect and optimal parameters of electroacupuncture on post-stroke dysphagia: a meta-analysis of randomized controlled trials

Electroacupuncture, in conjunction with dysphagia training, is more effective than a solitary treatment in patients with PSD. Furthermore, applying waveforms with Ds-W might enhance the effectiveness of electroacupuncture for PSD. However, the higher risk of bias (ROB) in the included trials indicates that the quality of evidence for the outcomes of these assessments may be jeopardized. Thus, further high-quality clinical trials are urgently required to evaluate the efficacy and effectiveness of electroacupuncture parameters (waveforms) in the treatment of PSD, ultimately increasing the total level of evidence (PROSPERO registration number: CRD420251014881, https://www.crd.york.ac.uk/prospero/).
