Objective To discuss the research status and frontiers of dysphagia after stroke in China and abroad in recent ten years.

Methods The CiteSpace software was used to analyze the literature related to swallowing disorders after stroke in the core database of CNKI and Web of Science.

Results The literatures meeting the requirements from 2011 to 2021 were searched, and 959 were included. At present, the most published author published the most literatures in China was YAO Yunhai; the most productive author abroad was PAINER DZIEWAS. In China, it had formed 11 representative keyword clusters such as "acupuncture" and "swallowing function" and 14 emergent words with high change rates such as "swallowing training" and "quality of life". In foreign countries, 10 representative keyword clusters such as "dysphagia screening" and "neuroimaging" were formed, and 13 emergent words with a high rate of change such as "aspiration" and "early management" were formed.

Conclusion Treatment, management and complications caused by dysphagia are the focus of research in this field. Research trends in China focus on patients' quality of life and evidence-based research; the international research trends focus on mechanisms and early management of swallowing function.
