ABSTRACT
Objective:To analyze the trend and hot spots of research on multimorbidity.Methods:The Chinese and English literature in databases of CNKI, Wanfang data and Web of science from inception to July 2022 were retrieved using "multimorbidity" and "multiple chronic conditions" as the search terms. The scientific knowledge mapping software VOSviewer was used to analyze the co-occurrence network of scientific knowledge from the aspects of countries, Chinese and English keywords,burst terms and existing research results; and the status quo and hot trends of studies on multimorbidity at home and abroad were summarized and compared.Results:A total of 251 Chinese publications and 6 351 English publications were included. From the perspective of research trends, the overall trend of domestic and international publications showed a fluctuating upward trend in general, but the pace of development was different. The cooperation network represented by the United States, England, Canada, China, Japan, Australia and other countries was the largest regional cooperation network. Germany, the Netherlands, the United States, Australia and other countries were the first regions to carry out studies on multimorbidity. Studies on multimorbidity in China mainly focused on three topics: diagnosis, treatment and care of multimorbidity, common disease management of multimorbidity, and research methods of multimorbidity. The English literature mainly focused on the clustering of three topics: multi-disease co-diagnosis and care research, multi-disease co-management model research, and multimorbidity related research. The analysis of burst terms indicated the research focus and trend change in different time periods. The results of the outburst word analysis showed that the recent research hotspots of multimorbidity were public health, machine learning, geriatric medicine and so on.Conclusions:The number of studies on the multimorbidity is rapidly increasing both domestically and internationally, and related research in China is still in the early stages of development. In terms of research hotspots, the research of multimorbidity has gradually shifted from phenomenon description to topics such as medical services and research methods of multimorbidity.

ABSTRACT
ObjectiveTo conduct a visualized analysis of the research related to the use of brain-computer interface technology for stroke rehabilitation in the past ten years, and identify and predict the hot spots and hot trends in order to promote the further development of this field. MethodsThe Web of Science Core Collection database was searched for literature related to brain-computer interface technology for stroke rehabilitation from January, 2011 to October, 2022. CiteSpace 5.8.R3 was used to analyze the number of publications, countries, institutions, authors, keywords, co-citations, and grant support. Results and ConclusionA total of 592 papers were included, and the annual number of publications in this field of research showed a rapid growth trend, and the research enthusiasm continued to increase. The United States was in the leading position in this field, with the highest number of cooperative publications and the highest intermediary centrality; China had certain advantages in this field, but still needed to strengthen the exchange and cooperation with other countries/regions. Foreign institutions and authors had formed a network of close cooperative relationships, and formed a high-impact team represented by Niels Birbaumer, Cuntai Guan, Kai Keng Ang, etc.; there were poor cooperative relationships among domestic authors and institutions, and there were geographical restrictions and lack of high-impact academic groups. The keywords "motor imagery" and "recovery" formed ten major clusters and 15 prominent words with high variation rates, showing a trend of diversification in research directions. The study of the efficacy of upper limb motor rehabilitation and central mechanisms has been the hot topics in this field and will continue for some time in the future; the use of lower limb brain-computer interface systems for improving foot drop, gait and balance in stroke patients and the application of multimodal brain-computer interfaces will probably become a hot topic in the future. Finally, the use of brain-computer interface-guided neurofeedback training for cognitive and language rehabilitation in stroke also needs attention.

ABSTRACT
ObjectiveTo perform a visualized analysis on the relevant literature about rehabilitation in pelvic floor dysfunction (PFD) domestic and abroad, and summarize the current hot spots and frontiers in this field. MethodsThe literature related to PFD rehabilitation from January, 2012 to June, 2022 was searched and screened from the databases of CNKI and Web of Science, and the CiteSpace software was used to analyze the trends of publications, authors, institutions and key words. ResultsA total of 2 448 articles were included. Relatively few high-quality domestic researches were published. In terms of research hotspots, both domestic and international researches focused on causes, mechanisms, rehabilitation techniques and evaluation indicators of PFD, but domestic researches had not paid enough attention to evaluation indicators and prevention of PFD. The key words constantly appeared in 2022 were mechanisms of PFD due to pregnancy, treatment of postoperative complications in prostate cancer patients, the role of pelvic floor muscle training, and quality of life studies in women. ConclusionResearch related to the field of PFD rehabilitation is increasing. There is still a large gap for future development in China.
ABSTRACT
ObjectiveTo understand the current research status, research hotspots and development trends of constraint-induced movement therapy (CIMT) in the field of rehabilitation. MethodsThe relevant articles of CIMT in rehabilitation from January, 2000 to October, 2022 in CNKI and Web of Science were retrieved. The authors, institutions, countries, keywords and burst words were extracted with CiteSpace 6.1.R3 to draw knowledge mapping. ResultsA total of 1 165 articles were included, 359 articles in Chinese and 806 in English. The trend of annual publications was generally consistent, and after a period of rapid growth, the current annual publications showed a fluctuating trend. There was more cooperation among the institutions in English articles, with geographical limitation. The institutions in Chinese articles had the problem of insufficient cooperation. The researches mainly focused on the application of CIMT in different diseases, the improvement of motor function by CIMT, the application of CIMT in combination with other therapies, and the study of the related mechanisms of CIMT. In recent years, Chinese burst keywords included modified constraint-induced movement therapy, stroke hemiparesis, clinical efficacy and repetitive transcranial magnetic stimulation; English burst keywords included transcranial direct current stimulation, non-invasive brain stimulation, and unilateral cerebral palsy. ConclusionResearch on CIMT in the field of rehabilitation is in a period of steady development, and CIMT combined with non-invasive brain stimulation is likely to be a hotspot in future research.

ABSTRACT
ObjectiveTo analyze the research hotspots and development trends of postpartum rehabilitation at home and abroad in the past ten years. MethodsCiteSpace 6.2.R2 was used to analyze the co-occurrence, cluster, and bursting of keywords of the relevant literature in the field of postpartum rehabilitation in CNKI and Web of Science (WOS) in the past ten years. ResultsTotally, 2 686 Chinese papaers were included in CNKI and 1 247 English papers were included in WOS. Both databases showed an increasing trend in the number of publications related to the field of postpartum rehabilitation, but the overall number of publications in CNKI grew faster and the total number of publications was more than that in WOS. For CNKI, there were 455 nodes, 1 102 links, with a density of 0.010 7; nine clusters were obtained; the bursting keywords showed that the diseases of concern shifted from breast distension and pain to pelvic floor diseases, and the hot spots of treatment methods shifted from Chinese medicine to electrical stimulation, biofeedback, and then pelvic floor training. For WOS, there were 463 nodes, 1 633 connected lines, with a density of 0.015 3; 14 clusters were obtained; the bursting keywords showed that the disease hotspots of concern shifted from anal prolapse and postpartum hemorrhage to organ prolapse, the hotspots of treatment methods shifted from analgesia to exercise, and the focus of research methods shifted from trial to qualitative research and meta-analysis. ConclusionDomestic postpartum rehabilitation started later than foreign countries. Although certain research results have been achieved, there is still a certain gap compared with the development of foreign postpartum rehabilitation.
ABSTRACT
ObjectiveTo summarize the current situation, hot spots and frontiers of the application of functional near-infrared spectroscopy (fNIRS) in rehabilitation in recent ten years. MethodsLiterature related to the application of fNIRS in rehabilitation was retrieved from the core collection of Web of Science from January, 2003 to December, 2022, and the visualized analysis was performed by CiteSpace 6.1.R6 software. ResultsA total of 828 literatures were included. The annual publication volume was on the rise. The most prolific author was LI Zengyong. The most published country was the United States. And the most published institution was Karolinska Institute. Hot keywords included children, stroke, activation, quality of life, cerebral palsy, etc. The hot keywords of bursting intensity included early intervention, speech perception, cerebral palsy, plasticity, spinal cord injury, physical therapy, visual feedback, Parkinson's disease, etc. Cluster analysis suggested that in the past decade, the application of fNIRS in rehabilitation involved physical therapy, speech therapy, occupational therapy, pre-rehabilitation and early rehabilitation of surgery, mainly focusing on six themes: the rehabilitation of motor dysfunction after stroke, cognitive impairment, hearing and speech dysfunction, children with cerebral palsy, cardiopulmonary function monitoring in severe diseases and long-term nursing of chronic diseases. Among them, the application of fNIRS in neurological rehabilitation of stroke patients occupied a large proportion, which might be the current research hot spot and trend. ConclusionThe application of fNIRS in rehabilitation is on the rise. In the future, more attention should be paid to the application of fNIRS in the study of the injury and recovery mechanism of neurological disorders, especially the effects of various rehabilitation interventions on cortical plasticity and the etiology of neurological disorders.
ABSTRACT
ObjectiveTo visualize the research trends of verbal and nonverbal cognitive functions in patients with post-stroke aphasia (PSA). MethodsPapers about verbal and nonverbal cognitive functions after stroke were extracted from Web of Science Core Collection from establishment to August, 2022, and a bibliometric analysis was conducted on the distribution of articles published by year, author, journal, institution, and country. Author cooperation, author co-citation, journal co-citation, country/institution cooperation, dynamic evolution, keyword hotspots, and trends were visually analyzed by using VOSviewer software. ResultsA total of 1 630 publications were identified for final analysis. The first article related to the topic was retrieved in 2004. After that, the number of published papers showed an increasing trend year by year, with some fluctuations after 2019. Matthew A. Lambon Ralph and Elizabeth Jefferies were the authors who produced the most, were cited the most, and were the most influential. Neuropsychologia was a highly productive and well-cited publication. The University of Manchester in the United Kingdom and Johns Hopkins University in the United States were the nations/institutions with high yield and high centrality. Although China had a high yield and was in the top five, the centrality was insufficient. The dynamic emergence of keywords revealed that the research had gone through the following stages: evaluating the mechanism of language and nonverbal cognitive function impairment based on neuroimage, exploring the role of nonverbal cognitive dysfunction in pathology and recovery mechanisms of patients with PSA, examining the therapeutic mechanism of non-invasive brain stimulation and electronic tele-rehabilitation equipment, and revealing not only the frontal and temporal areas but also brain network supporting nonverbal cognition. ConclusionIn recent years, some achievements have been made in the researches on verbal and nonverbal cognitive function, particularly in the studies of the neuroimaging-based mechanisms of common damage and the intervention effects of synergistic therapy. In the future, academic cooperation between different regions and different teams needs to be strengthened. Further exploration should be focused on refining the cognitive neuropsychology and exploring new technologies to improve the therapeutic effect of PSA.
