Bibliometric Study of Pain after Spinal Cord Injury

Abstract

Background. The prevalence of comorbid pain after spinal cord injury (SCI) is relatively high in clinical observations and has continued to increase over time. Neuropathic pain (70.14%) is the most popular subject in academic journals after SCI. However, studies that used the bibliometric method to analyze comorbid pain after SCI are still lacking. This study is aimed at combining and integrating acquired information to analyze the global trends of research on the comorbidity of pain after SCI in the last three decades (1990–2019). Methods. Systematic works of literature published from 1990 to 2019 were obtained from the Web of Science Core Collection. CiteSpace software was used to analyze the relationship of publication year with the country, institution, journals, authors, references, and keywords. The regression analysis is used to evaluate the percentage of the category increase or decrease over time significantly. IBM SPSS Statistics was used in the statistical analysis. Results. A total of 730 publications were included in the analysis. A remarkable increase in the number of publications was observed in the study period ( P < 0.05 ). A total of 202 academic journals focused on the categories of clinical neurology, neurosciences, and rehabilitation, and the annual growth rate of articles in these three categories was statistically significant ( P < 0.05 ). The USA (356, 48.77%) and the University of Miami (64, 8.77%) were the country and institution with the highest number of publications, respectively. Spinal Cord, which was the main journal for research on pain after SCI, had the most publications (88, 12.05%). Burst keywords showed that the individual, inflammation, and central sensitization with pain after SCI are the research development trends and focus in this research field. Conclusions. Overall, this study provides the latest research direction for pain after SCI. This historical overview of research into pain after SCI will be a useful basis for further research into development trends, focus issues, cooperators, and cooperative institutions.

Scientific Knowledge Graph and Trend Analysis of Central Sensitization: A Bibliometric Analysis

“…It is well known that in recent years there had been a significant increase in the number of publications in the field of pain, such as pain after spinal cord injury, 37 chronic postsurgical pain, 38 etc. As shown in Figure 1 , the number of CS-related articles was on a very steady upward trend, which indicated a great potential for future development.…”

“… 42 Besides, “central sensitization” was the research development trends and focus in the pain field after spinal cord injury. 37 Nowadays, there are a growing number of double-blind studies advancing the clinical application of the concept of CS, deepening the understanding of a variety of diseases such as osteoarthritis and migraine. 54–57 CS-related changes in functional brain activity can be observed in rats with endometriosis-related pain: enhanced ReHo signaling in the cingulate cortex, thalamus, and hippocampus, which may be due to neuronal apoptosis or hyperactivity.…”

Knowledge Domains and Emerging Trends of Osteoblasts-Osteoclasts in Bone Disease From 2002 to 2021: A Bibliometrics Analysis and Visualization Study

“…The data analyzed in bibliometrics were downloaded from the WOS database. This database was selected because it currently contains more than 12,400 authoritative and high-impact academic journals worldwide, and thus is regarded as the most influential database that can provide the comprehensive data information required by bibliometrics software (12,(15)(16)(17). The advanced search entry in the database was set as "osteoblast &…”

“…However, CiteSpace was selected owing to its wide range of functions, which not only include network analysis and network visualization but also turning points, clustering automatic naming, macro theory, double graph superposition, concept tree, and timeline functions. As the heat map function of VOSviewer is not available in other analysis software, this software (VOS viewer 1.6.18) was selected, along with CiteSpace 5.8, for visual analysis and knowledge mapping, respectively (12,17,18).…”

Research Hotspots and Effectiveness of Transcranial Magnetic Stimulation in Pain: A Bibliometric Analysis

“…Based on cocitation analysis theory and pathfinding network algorithm, CiteSpace software can analyze literature of specific disciplines or fields from multiple perspectives and draw visual maps, so as to explore the critical paths, research hotspots, and frontiers of the evolution of this discipline or field (Chen and Song, 2019). In recent years, using CiteSpace software combined with relevant authoritative databases to analyze the literature visualization of a certain discipline or field has become a hot research topic for scholars all over the world (Chen et al, 2012;Ugolini et al, 2013;Xu and Sun, 2020;Wang et al, 2021). The aim of this study was two-folded: (1) perform a visual analysis of TMS in pain studies using CiteSpace software, and (2) objectively clarify the time changes of research hotspots and dynamic frontiers in this field.…”
