Abstract: BACKGROUND: Currently, experimental research on electroacupuncture intervention for peripheral nerve injury is rapidly developing, involving various nerves and disease types. A bibliometric analysis of this field holds significant value.
OBJECTIVE: To summarize the development history, current research status, hotspots and future trends in the field of experimental research on electroacupuncture intervention in peripheral nerve injury.
METHODS: Literature related to electroacupuncture intervention for peripheral nerve regeneration was retrieved from CNKI, CBM, and Web of Science Core Collection databases up to December 2024. After screening, deduplication, and data cleaning, CiteSpace and VOSviewer were used to analyze the data and generate visual knowledge maps.
RESULTS AND CONCLUSION: A total of 432 articles were included (181 from CNKI, 186 from CBM, and 65 from the Web of Science Core Collection). The annual publication count showed a fluctuating upward trend, with a number of core authors identified, but author and institutional distributions remained scattered without forming a cohesive core group. Chinese-language articles contained 599 keyword nodes, while English-language articles had 364. The main disease focuses were mononeuropathy, neuropathic pain, and diabetic peripheral neuropathy. Research depth has progressively increased, with current studies concentrating on optimal electroacupuncture parameters, acupuncture effects, and molecular mechanisms for these conditions. Astrocytes and microglia emerged as burst terms in Chinese and English literature, respectively. Future efforts should intensify experimental research on electroacupuncture intervention for peripheral nerve injury by enhancing collaboration among authors and institutions, integrating advanced technologies such as materials science and high-throughput sequencing, to identify new breakthroughs. These measures will collectively promote high-quality research output and advance the field.
