Objective:To analyze the hotspots and frontiers of floating needles using bibliometric study and clarify the developmental trends of the field.Methods:The trends,authors,institutions and keywords of the papers on floating needles were analyzed between 1996 and 2021 using bibliometric methods such as co-occurrence analysis,cluster analysis and burst detection,and information visualization software CiteSpace analysis.Results:The cooperative team map with the core of Fu Zhonghua was obtained by the author collaboration network;the first institution in terms of number of documents issued was the Guangdong Second Traditional Chinese Medicine Hospital,which issued 17 documents;the trend of publications showed that the studies on floating needles have developed faster since 2002,and the publications increased rapidly,basically conforming to the exponential model of y=3E-120e0.1385x,R2=0.9243,all 135 documents are expected to be issued in 2021,and total literature would exceed 900 documents;the main cluster of the keywords contain floating needles,the affected muscles,lumbar disc herniation,knee osteoarthritis and cervical spondylosis,the top ten keywords in terms of frequency,obtained by co-occurrence analysis,cover floating needles,floating needles therapy,lumbar disc herniation,acupuncture,frozen shoulder,acupuncture therapy,reperfusion activity,clinical effects,clinical observation and pain;the buzzwords in the field of floating needles in the recent four years obtained by emergent analysis are reperfusion activity,clinical effects,the affected muscles and Meta analysis.Conclusion:Clinical efficacy of floating needles and reperfusion activity are the research hotspots at present,high-quality clinical studies are needed for elaboration and validation.
