Study of acupuncture for low back pain in recent 20 years: a bibliometric analysis via CiteSpace

Abstract

BackgroundAcupuncture has been applied to relieve low back pain (LBP) in many countries. However, a bibliometric analysis of the global use of acupuncture for LBP is rare.ObjectiveThe aim of this study was to demonstrate the state of the art and trends concerning the global use of acupuncture for LBP in recent 20 years.MethodsLiterature relating to acupuncture for LBP from 1997 to 2016 was retrieved from Web of Science. CiteSpace was used to analyze country/institution, cited journals, authors/cited authors, cited references, and keywords. An analysis of counts and centrality was used to reveal publication outputs, countries/institutions, core journals, active authors, foundation references, hot topics, and frontiers.ResultsA total of 958 references were obtained, and the total number of publications continually increased over the investigated period. Journal articles (662) were the most frequently occurring document type. The most productive country and institution in this field was the USA (342) and Harvard University (47), respectively. The J Altern Complem Med (69) was the most productive journal, and Pain (636) was the most cocited journal, which reflected the nature of the research. The Haake’s (2007) article (cocitation counts: 130) and the Cherkin’s (2001) article (centrality: 0.59) were the most representative and symbolic references, with the highest cocitation number and centrality, respectively. Cherkin was the most influential author, with the highest number of publications of 25 and a cocitation number of 226. The four hot topics in acupuncture for LBP were research method, evaluation, economy, and comprehensive therapy. The three frontier topics were intervention, test reliability, and prevalence.ConclusionThis study provides an insight into acupuncture for LBP and valuable information for acupuncture researchers to identify new perspectives on potential collaborators and cooperative institutions, hot topics, and research frontiers.

Depicting developing trend and core knowledge of hip fracture research using bibliometric and visualized analysis

“…The size of the nodes re ected the amount of the publications or frequency 11 . The links between nodes represented the associations including coauthorship or co-occurrence, while the color of the node/lines re ected diverse clusters or years 12 . The strength of the link was presented as total link strength (TLS).…”

A narrative review of non-operative treatment, especially traditional Chinese medicine therapy, for lumbar intervertebral disc herniation

“…Advice to stay active and to continue ordinary activities results in a faster return to work, less chronic disability, and fewer recurrent problems (23). Moreover, two systematic reviews conducted by Hagen et al and Hilde et al showed that for nonspecific low back pain, there is strong evidence that advice to stay active rather than rest in bed results in less time missed from work, improved functional status, and less pain, while for patients with sciatica, there is no difference as a type of TCM therapy, has shown respectable efficacy and is broadly accepted internationally (32).…”
