Background: Following total knee arthroplasty (TKA), postoperative patient rehabilitation is important to achieve the optimal level of knee function and mobility. Clinical research in this field is growing, and bibliometric analysis of publication may provide direction for research clinicians and raise awareness of research trends, journal selection, and key topics. Therefore, this bibliometric study aimed to analyze the current status and trends during the past two decades, between 1999 and 2018, of publications on rehabilitation after total knee arthroplasty (TKA) and used CiteSpace. Material/Methods: The global literature was searched between 2018 to 2019 for publications related to rehabilitation after TKA. Publication data were identified using relevant search terms and the Web of Science Core Collection database. CiteSpace (5.3.R11) software was used to analyze the journals, authors, institutions, countries, cited references, and keywords using standard bibliometric indicators. Results: A total of 1,292 publications were retrieved between 1999 to 2018, and the most active journals, countries, authors, and institutions in the field of TKA rehabilitation were identified. Key areas of research included postoperative analgesia, muscle inhibition, range of motion, inhibitors, knee flexion, pain control, self-reporting, spectral analysis, in vivo forces, and rotator cuff repair. The emerging research topics included epidural analgesia, physiotherapy, postoperative analgesia, recovery, and the use of ropivacaine local analgesia. Conclusions: The findings from this bibliometric study provided insight into trends in clinical research publications in the field of rehabilitation following TKA for the past 20 years, including global trends in emerging areas of research.
Objective: To investigate whether hip abductor strength–based exercise therapy could result in further function improvement and more pain relief in women with knee osteoarthritis. Design: Randomized controlled trial. Settings: Rehabilitation department of Affiliated Hospital of Southwest Medical University from years 2016 to 2018. Subjects: In total, 82 women aged 50–70 years, with knee osteoarthritis grade II–IV on the Kellgren–Lawrence scale. Intervention: The experimental group engaged in hip abductor strength–based exercises under the supervision of physical therapists (once a day for six weeks), while the control group engaged in quadriceps femoris strength–based exercises. Main measures: Osteoarthritis severity measured by the Western Ontario and McMaster Universities Osteoarthritis Index, pain on a visual analogue scale and three objective functional tests were assessed at the sixth and 12th week. Repeated measures analysis of variance and multivariable analysis were applied. Results: Finally, 72 participants completed the study: 35 in the experimental group and 37 in the control group. The self-reported functional difficulties score in the experimental group was significantly lower than that in the control group both at the sixth week and at the 12th week ( P < 0.001). There were significant differences between groups in the stair ascent/descent task and Figure of 8 Walk test, but not in the Five Times Sit-to-Stand Test. The pain in the experimental group decreased compared with that in the control group at the sixth week ( P < 0.05), but not at the 12th week ( P > 0.05). Conclusion: Hip abductor strength–based exercises could result in better performance and higher self-reported function in women with symptomatic knee osteoarthritis.
Delirium is a cognitive disorder with complex etiology, which brings a great burden to social health care. Articles with high citation frequency can provide important information about the current research situation in a certain field. Web of Science was used to search the 100 most-cited articles and we extracted key information, such as the authors, countries/regions, institutions, journals, and study types of these articles. CiteSpace was used to visually analyze the keywords. Our bibliometric analysis shows that the attention in this field continues to rise. Authors from the United States published the most articles and Inouye SK is the most influential author in the field. The journals that published these articles have high impact factors. Cohort studies are the main cited articles in this field, and there are a large number of systematic reviews or meta-analyses of cohort studies. Risk factors for delirium, psychometric evaluation, hospital care, and various clinical study design are still the focus of research. In short, we summarized the 100 most-cited articles in the field of delirium to identify the current status and global trends. These results enable researchers to understand the quality and trend of research in the field of delirium and make better use of the classical literature.
BackgroundNon-coding RNAs (ncRNA) are a kind of RNA that does not encode protein, which play an important role in Alzheimer’s disease (AD). However, there is a lack of bibliometric analysis and visualization analysis of the research related to AD and ncRNAs.Materials and methodsLiterature related to AD and ncRNAs in the last decade were searched through the Web of Science Core Collection (WOSCC). The relevant information from all the searched articles was collected. The bibliometric visualization website, CiteSpace, and VOSviewer were used for visualization analysis of countries/regions, institutions, authors, and keywords.ResultsIn total, 1,613 kinds of literature were published in the field. Literature in this field were published in 494 journals. The Journal of Alzheimer’s Disease was the most popular journal. China, Louisiana State University System, and Lukiw WJ were the countries/regions, institutions, and authors with the highest scientific productivity, respectively. The research hotspots in this field focused on the role and mechanism of ncRNAs, especially microRNAs, in AD. The level of research was mainly based on basic research, focusing on animal and cellular levels, and related to proteomics. “Circular RNAs,” “regulation of neuroinflammation,” and “tau protein” were the future research directions.ConclusionTaken together, the field of AD and ncRNAs is developing well. The research hotspots and frontiers in this field can provide a reference for researchers to choose their research direction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
