To systematically evaluate the effect of various interventions on the improvement of swallowing function in patients with Parkinson's disease. Methods: CNKI, Wanfang, VIP, CBM, PubMed, Medline and Web of science databases were searched to collect RCTs on different treatment methods for dysphagia in Parkinson's patients from inception to March 15, 2024. RevMan 5.4.1 software was used to evaluate the quality of the included studies, and Stata 17.0 software was used for network meta-analysis. Results: A total of 29 studies involving 1 870 patients were included, involving 13 treatment methods such as acupuncture, electrical stimulation, and respiratory training. The results of network meta-analysis showed that the best training effect was respiratory training in improving the clinical efficiency and PAS of Parkinson's disease. In terms of improving SSA and Kubota drinking water scores, repetitive transcranial magnetic stimulation and electrical stimulation have the best effect. Conclusion: The existing evidence shows that respiratory training is the most likely to be the best intervention for Parkinson's dysphagia. Repetitive transcranial magnetic stimulation and electrical stimulation also have certain advantages.
