Research Trends on Acupuncture for Shoulder Pain Treatment Over the Past 15 Years: A Bibliometric Analysis

Objective: Currently, acupuncture for shoulder pain has been widely used in clinical and scientific research worldwide, but the bibliometric literature on acupuncture for shoulder pain is still scarce. This study reviews the application of acupuncture in the treatment of shoulder pain over the past 15 years, to analyze the current state of research, research hotspots, and trends. The article can also provide a reference for future research.Methods: This paper searches the core collection of the Web of Science database for publications related to acupuncture therapy for shoulder pain between 2008 and 2022. And the data were visualized and analyzed using VOSviewer and CiteSpace for annual publications, countries, institutions, journals and co-cited journals, authors and co-cited authors, keywords, and emergent keywords. Results: A total of 135 papers were included, with an overall increasing trend in the number of annual publications. The country with the highest centrality in publishing articles is the United States (0.28). In terms of research institutions, Kyung Hee University has the highest number of publications (18). In terms of authors, Lewith George, Lind Klaus, MacPherson Hugh, Sherman Karen J, and Vickers Andrew J are the five most published authors. Vickers, Andrew J. is the most co-cited author (50 times). In terms of journals, PAIN has the highest number of publications (82) and co-cited frequency (232), while the highest impact factor was BMJ-BRIT MED J (96.216). "Acupuncture" was the most frequently mentioned keyword (65 times), with the keyword "protocol" appearing the most recently. Emerging keywords that are still in vogue are "stroke", "systematic review" and "stimulation".Conclusion: This study provides statistics on current research on the treatment of shoulder pain with acupuncture, which may be able to inform future research directions for all researchers and physicians, as well as facilitate closer communication and collaboration.
