Abstract：Objective To analyze the relevant literature of lower limb rehabilitation robots in the past 20 years by using the CiteSpace
knowledge atlas, and to summarize the frontier hotspots and development trends in this research field. Methods The computer
was used to search the papers about lower limb rehabilitation robots from January 2002 to August 2022 collected by CNKI, and
NoteExpressV3.5 was used to manage and de-duplicate the papers. CiteSpace.V.6.1.R2 software was used to co-exist, cluster and
highlight the papers, authors and keywords in the included literature, and draw the corresponding knowledge map. Results A total
of 490 literatures were included, including 1364 researchers. There were 28 main researchers, and the number of published
papers was ≥5, and the most prominent author was Lixun Zhang, with 15 papers. A total of 387 research institutions were included,
30 main research institutions, and the number of papers issued was ≥4. Among them, the School of Mechanical and Electrical
Engineering of Harbin Engineering University has the most literature research, with a total of 13 papers issued from 2002 to 2022.
A total of 444 keywords were included, including 20 high-frequency keywords with frequency ≥10. A total of 15 cluster tags were
formed, and the research trends and research frontiers of lower limb rehabilitation robot in recent years were
studied by keywords. Conclusion The number of papers published in the research field of lower limb rehabilitation robots
shows an overall upward trend. Through the visual analysis of knowledge atlas, the research status and hot directions of lower limb
rehabilitation robots are displayed, providing a basis for further development trends. At present, the main research directions of lower
limb rehabilitation robots are kinematics, walking function, simulation analysis, exoskeleton and so on.
