Advance in post-stroke dysphagia in the last five years: a visualization analysis

Objective To explore the current status, hot spots and development of researches on post-stroke dysphagia in recent five years with visualization analysis. Methods Researches on post-stroke dysphagia were retrieved from Web of Science Core Collection, from January 1st, 2017 to December 31st, 2021, and reviewed with CiteSpace 5.7.R5 software. Results A total of 857 articles were included. The annual number of articles increased with time, published from 61 countries/regions, by 211 institutions and 247 authors. The United States, Japan and China were the most prolific countries, and the University of Manchester was the leading institution. The top three authors were Dziewas R, Wakabayashi H and Hamdy S. The keywords bursting in recent three years included prediction, severity, percutaneous endoscopic gastrostomy, accuracy and early management; co-word clustering showed that researches might be mainly about neuromuscular electrical stimulation, swallowing screening, stroke-associated pneumonia, evidence-based practice, etc. Conclusion The researches in the field of post-stroke dysphagia have been increasing.
