Global trends in acupuncture research: A scientometric analysis from 1980 to 2023

The objective of this study was to examine articles on acupuncture from past to present, revealing prevalent research trends, showcasing global productivity, identifying international collaborations, and highlighting influential publications and journals in the field. We acquired a comprehensive dataset comprising 9340 articles pertaining to acupuncture that were published within the time frame spanning from 1980 to 2023. These articles were sourced from the Web of Science and underwent rigorous analysis through a diverse set of bibliometric techniques. Our analytical approaches encompassed trend keyword analysis, thematic evolution analysis, conceptual structure analysis, factor analysis, citation and co-citation analyses, as well as an exploration of international collaboration patterns. The 3 most productive countries were China (n = 3357), the USA (n = 1351), and South Korea (n = 814). The 3 most productive journals were Acupuncture in Medicine (n = 440), Evidence Based Complementary and Alternative Medicine (n = 415), and Medical Acupuncture (n = 400). The 3 journals with the highest h-index on acupuncture were the Journal of Alternative and Complementary Medicine (h = 45), Pain (h = 41), and the American Journal of Chinese Medicine (h = 35). The most active author was Park Hi-Joon (n = 128). According to the findings of the factor analysis, acupuncture literature was grouped around 3 main subfactors. The primary factor encompassed topics related to the effectiveness/applicability of the treatment method for various medical conditions and general principles of acupuncture methods and points. The second factor covered topics related to mental health and quality of life. The third subfactor addressed the qualitative and quantitative analysis direction of acupuncture, such as meta-analysis and systematic reviews, and randomized controlled trials. From the past to the present, the most extensively researched main topics in acupuncture literature have covered a wide range of subjects. Prominent themes among these topics included acupuncture methods and applications, pain management, the nervous system and acupuncture, mental health and acupuncture, quality of life, and general health. In recent years, emerging trends in acupuncture research have focused on neurological health issues, oncology and cancer treatment, women's health and hormonal issues, sleep problems, digestive issues, and studies related to the quantitative and qualitative evaluation of acupuncture research.
