Summary
This study analyzed 1,447 publications on post-stroke dysphagia from 2013-2022. Research shows an increasing trend, focusing on dysphagia classification, rehabilitation, and aspiration to improve patient quality of life.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Bibliometrics
Background:
- Dysphagia is a frequent and serious complication following stroke.
- A growing body of literature exists on post-stroke dysphagia, yet a bibliometric analysis was lacking.
- This study aims to map the global research landscape of post-stroke dysphagia from 2013 to 2022.
Approach:
- A bibliometric analysis was conducted on 1,447 articles and reviews retrieved from the Web of Science core collection (2013-2022).
- CiteSpace and Microsoft Excel 2019 were utilized for data analysis and visualization.
- The analysis focused on publication trends, influential entities, and keyword co-occurrence to identify research hotspots.
Key Points:
- Publication output on post-stroke dysphagia demonstrated a significant upward trend between 2013 and 2022.
- The People's Republic of China, the University of London, and the journal 'Dysphagia' were identified as leading contributors.
- Prominent research themes included dysphagia classification, aspiration, rehabilitation strategies, and impact on daily living.
Conclusions:
- The bibliometric analysis highlights key advancements and emerging trends in post-stroke dysphagia research.
- There is a critical need for large-scale randomized controlled trials on dysphagia screening and non-invasive interventions.
- Future research should focus on evidence-based strategies to enhance the quality of life for stroke survivors with dysphagia.
