BACKGROUND: Patellofemoral pain syndrome is a common disease in the field of sports injuries. Research in and outside China is increasing year by year, but there is no visual analysis for patellofemoral pain syndrome. OBJECTIVE: To objectively analyze the literature research on patellofemoral pain syndrome in and outside China in the past 13 years, to summarize the recent research directions in this field and to sort out the knowledge structure in and outside China. METHODS: Relevant articles on patellofemoral pain syndrome were collected from Web of Science and CNKI. Citespace software was used for visual analysis to show the research hotspots and development trends of this field. RESULTS AND CONCLUSION: (1) A total of 1 679 articles were finally included in the Web of Science database. The authors with the most articles are De Oliveira Silva D from La Trobe University in Melbourne, Australia and Crossley KM from the University of Melbourne, Australia. Hot keywords are hip, biomechanics, prevention (prognosis), prevalence disease rate, consensus statement, gender differences, electromyographic activity, risk factor, and osteoarthritis. (2) A total of 214 articles were included and analyzed in the CNKI database. The author with the most articles is Miao Ping from the Rehabilitation Department of the Second Affiliated Hospital of Guangzhou Medical University. Hot keywords are arthroscopy, biomechanics, strength training, lateral femoral muscle, surface electromyography, patellofemoral arthritis, and joint replacement. (3) International research hotspots show the biomechanical characteristics of increased knee external rotation, increased hip adduction, and decreased hip internal rotation during patient exercise. Strengthening the hip abductors and external rotators can effectively improve the pain and function of patients. At present, the most appropriate method to treat the disease in the world is a customized multi-modal intervention program, including strengthening of the gluteal muscles and quadriceps, emphasizing education and activity adjustment. (4) The results of major Chinese studies in this field confirm that the use of arthroscopic surgery can improve the pain of patients with patellofemoral pain syndrome, and patellofemoral joint replacement has a certain effect on early severe patellofemoral arthritis in such patients. Rehabilitation training methods are mainly based on hip joint strength training, supplemented by core muscles, lower limb eccentric strength and neuromuscular control training. Compared with foreign countries, the unique research hotspots in China are acupuncture and Chinese medicine. [ABSTRACT FROM AUTHOR]

BACKGROUND: Transcranial magnetic stimulation (TMS) technology has been widely used in neuropsychology, rehabilitation medicine, and pediatrics, due to its advantages of painlessness, non-invasiveness, effectiveness and safety. However, there is yet no visual analysis of literature on TMS for treating stroke. OBJECTIVE: To objectively analyze global research on TMS in the treatment of stroke in recent 10 years, and summarize the recent research direction of this field and sort out the knowledge structure worldwide. METHODS: Based on the relevant literature on TMS for stroke in databases of CNKI and Web of Science, Citespace software was used to visualize the use of TMS in the treatment of stroke. The number, countries, authors, research institutions, keywords, cited references and journals of relevant literatures and funding grants were analyzed to explore the research hotspot and development trend in this field. RESULTS AND CONCLUSION: A total of 1 729 articles were included in the Web of Science database. Among them, the institution with the most publications was Harvard Medical School, and the country with the most publications was the United States, followed by China. China ranks first in international fund support. The hot keywords included rehabilitation, excitability, motor cortex and etc. As described in a representative English article, TMS therapy at a frequency of 1 Hz was found to improve patients’ motor function to a greater extent. A total of 455 literatures were included in CNKI database. Among them, the institution with the most publications was the Department of Rehabilitation Medicine of Huashan Hospital affiliated to Fudan University, and the hot keywords were rehabilitation, depression, motor function, aphasia and so on. As described in a representative Chinese article, high-frequency TMS was found to be more effective than low-frequency TMS in improving post-stroke depression and daily living ability. Further analysis of the results shows that, in recent 10 years, the international research frontier and future development trend mainly focus on the mechanism of TMS on cerebral cortical motor areas and the efficacy of TMS combined with other rehabilitation therapies (motor learning and mirror therapy) in the treatment of various functional disorders after stroke. In China, the research frontier and future trend mainly focus on TMS in the treatment of post-stroke depression and motor function. [ABSTRACT FROM AUTHOR]

BACKGROUND: Currently, there is still no visual analysis using Citespace software in the field of "Sports and Cognition. OBJECTIVE: As increasing concern has been paid on the effect of sports on cognition, to summarize the research development in this field that can provide references for researchers in relevant fields. METHOD: Web of Science database was retrieved as the following strategy: (Tl=(exercise AND cognit*) OR Tl=(exercise AND learning) OR Tl=(exercise AND memory) OR Tl={exercise AND feeling) OR Tl=(exercise AND thinking) OR Tl=(exercise AND imagination} OR Tl=(exercise AND language) OR Tl=(exercise AND perception)} AND type of literature:(Article OR Review). The length of search time was from January 1st 1989 to December 25th, 2018. Based on the 2 175 related literature in the Web of Science database, CiteSpace software was used for visual analysis. RESULTS AND CONCLUSION: In recent years, research on the field of "Sports and Cognition" has developed dramatically. The most popular countries and regions are mainly located in North America and Europe. The research in this field includes both applied research and basic research, involving almost all diseases associated with cognition. Aerobic exercise is mainly used, but it is unclear about the cognitive levels of different populations under different forms of aerobic exercises. Various classic research methods of many disciplines have been used in this field to study cognitive indicators and neurobiological indicators related to aerobic exercises. There are two major knowledge groups in this field, including "changes in cognition caused by sports" and "mechanism of cognition caused by sports." Further cross-regional and cross-national cooperation is needed. We should strengthen the research on the mode and intensity of various kinds of exercises and seek for the optimal exercise to improve the cognitive level of different populations, and use as many indicators as possible to assess the effects of exercise on cognition.
