ABSTRACT
ObjectiveTo explore the current status and frontier hotspots of functional near-infrared spectroscopy (fNIRS) in the field of stroke. MethodsRelevant literature on stroke and fNIRS from the Web of Science Core Collection (WoSCC) database was searched from its inception to July, 2023. VOSviewer, CiteSpace and Scimago were utilized for analysis of publication output, countries (regions) and institutions, international collaboration, co-cited references, co-occurring keywords and burst keywords. ResultsA total of 379 articles were included. The research activity in this field showed an overall upward trend with slight fluctuations in the early stage. Among the top five institutions by publication output, four were from China. Co-occurrence analysis revealed that Beihang University and Boston Children's Hospital were central in collaboration networks. This study involved 1 787 authors, with 120 core authors, in which the top five most cited authors were Li Zengyong, Li Wenhao, Huo Congcong, Dou Zulin and Song Ying. The publications in this field were primarily concentrated in disciplines such as neurology, psychiatry, ophthalmology and clinical medicine. Overlay visualization of journal co-citation networks demonstrated associations between medical, clinical, and neurology disciplines with psychology, education, and sociology. Co-occurrence and clustering analysis of keywords indicated research emphasis on stroke rehabilitation, integration of multiple technical modalities, and exploration of innovative training strategies and brain activation connectivity. The research evolution of fNIRS in the stroke domain revealed initial use of photodiode devices for cerebral ischemia reperfusion monitoring. Subsequent studies refined cortical activation through improved laser sources, avalanche photodiodes, single-task experimental designs and transcranial direct current stimulation. Later, research extended to whole-brain detection, multimodal stimulation and the combination of virtual reality technology with audiovisual stimulation, resulting in significantly enhanced brain activation. The application of brain-computer interface technology further facilitated direct restoration of motor function. ConclusionResearches in the field of stroke using fNIRS technology overall demonstrat a continuous upward trend. The researches focuse on post-stroke rehabilitation, integrating multimodal fusion, brain-computer interfaces, virtual reality, and sensory stimulation for real-time monitoring and personalized neurorehabilitation training strategies. It emphasizes interdisciplinary collaboration, expanding innovative research and the application of new technologies.
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.
ABSTRACT
Objective@#To investigate and summarize the effect of narrative nursing on anxiety and depression in patients undergoing coronary artery bypass grafting, and to provide reference for the formulation of clinical nursing plan.@*Methods@#A total of 61 patients underwent coronary artery bypass grafting were selected. 31 cases of narrative nursing were taken as the research group, and routine nursing was used in the other 30 cases as control group. Depression and anxiety were assessed by Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) before, 7 days after and 14 days after surgery.@*Results@#Totally 61 patients were successfully operated and no case died during hospitalization. There was no significant difference in SAS and SDS scores between the 2 groups before surgery. The SAS scores in the study group were 57.9±4.2, 50.8±4.9, 47.1±5.0 on the day of admission,7 days after operation and 14 days after operation, respectively, while those in the control group were 58.4±3.7, 57.9±5.2, 55.7±6.2. There were significant differences between the two groups after intervention (t=5.490, 5.973, P<0.01). The SAS score of the study group decreased 7 days after operation and 14 days after operation compared with that of the admission day (t= 6.125, 9.209, P < 0.01). The SDS scores in the study group were 54.3±4.6, 49.4±4.7, 42.7±4.8 on the day of admission,7days after operation and 14 days after operation, respectively, while those in the control group were 54.1±5.1, 52.3±5.6, 51.6±5.2. There were significant differences between the two groups after intervention (t=2.194, 6.949, P<0.01). SDS scores in the study group decreased 7 days after operation and 14 days after operation compared with the day of admission in this group, with significant differences (t=4.148, 9.715, P < 0.01).@*Conclusions@#Narrative nursing is helpful to relieve anxiety and depression in patients undergoing coronary artery bypass grafting.
