Background:
Dysphagia, a common complication after stroke, significantly hampers the recovery process of patients, both due to dysphagia itself and the additional complications it causes. Although a large number of articles have been published on post-stroke dysphagia (PSD), bibliometric analysis in this field is still lacking. This study aimed to provide a comprehensive understanding of the research hotspots and trends in PSD, thereby guiding future research efforts.
Methods:
The Web of Science Core Collection (WoSCC) database was searched for articles related to PSD from 2003 to 2022. Data were visualised and analysed using CiteSpace and VOSviewer.
Results:
A total of 3102 publications were included in the scientometric analysis, with a gradual increase in the number of papers published each year. The United States emerged as the country with the highest number of publications (625 articles), while the University of Manchester led with the most publications among institutions (67 articles). Notably, Dysphagia was both the most published (254 articles) and the most cited journal (11,141 citations). Among authors, Hamdy S emerged as the most prolific (52 articles), with Martino R being the most cited (1042 citations).
Conclusion:
Based on our findings, we anticipate that research hotspots in PSD will mainly focus on complications due to PSD such as stroke-associated pneumonia, stroke-related sarcopenia. Additionally, exploration into the mechanisms and parameters of noninvasive brain stimulation techniques for the treatment of PSD, as well as the rehabilitation needs of patients with PSD, are expected to be key focal points in future research endeavours.
