Objective To investigate the test-retest reliability and inter-rater reliability of the Fugl-Meyer assessment (FMA),Wolf's motor function test (WMFT),the box-block test (BBT) and the nine-hole peg test (NHPT) in assessing the upper limb motor function of stroke patients.Methods Eighteen stroke patients participated in the study.Each patient was assessed twice within 2 hours with the U-FMA,WMFT,the BBT and the NHPT.Two raters recorded each session separately.Test-retest reliability was investigated by comparing the assessment results of different sessions; interrater reliability was identified by analyzing the assessment results of different raters.Results The intraclass correlation coefficients (ICC) for the U-FMA were 0.988 on test-retest reliability and 0.959 on inter-rater reliability.The ICC of WMFT by mean and median time were respectively 0.996 and 0.393 on test-retest reliability and both 1.000 on inter-rater reliability.The ICC of WMFT by score mean was O.989 for test-retest reliability and 0.977 for inter-rater reliability.The ICC for test-retest reliability of the BBT using affected hand counts and the difference in counts between the affected and un-affected hand were respectively 0.975 and 0.982.The ICC of the NHPT using affected hand times and the difference between the affected hand and unaffected hand times were respectively 0.937 and 0.936 for test-retest reliability,and both 1.000 for inter-rater reliability.Conclusion The U-FMA,WMFT,the BBT and the NHPT are all measurements with good test-retest reliability and inter-rater reliability.They are reliable for assessing the upper extremity motor function of stroke patients.

Objective To investigate the criterion validity of Wolf motor function test (WMFT), BOX-BLOCK TEST (BBT), Nine-Hole Peg Test for assessing upper limb motor function in stroke patients with hemiplegia, as well as the correlation between them. Methods 21 stroke patients participated in the study. 21 stroke patients were assessed once with WMFT, BBT, Nine-Hole Peg Test and U-FMA by one rater. All the 4 tests were assessed on the same day for each patient. The total time of WMFT, the total score of WMFT, the counts of BBT, the time of Nine-Hole Peg Test and the sore of U-FMA were recorded. The Spearman correlation was used to analyze the criterion validity and the correlation. Results and Conclusion Both the total score of WMFT and the BBT counts correlated with U-FMA score (P<0.01). The time of Nine-Hole Peg Test and the total time of the WMFT were not correlated with U-FMA score (P>0.05). The total time of the WMFT and the total score of the WMFT were not correlated (P>0.05). The BBT counts and the total score of the WMFT were correlated (P<0.01). The time of Nine-Hole Peg Test and the total time of WMFT were correlated (P<0.01).

Objective To investigate the situation and progress in technology of brain computer interfaces (BCI) by using the bibliometric approach.Methods Literature searching was done in China national knowledge infrastructure (CNKI) database using keyword brain computer interface.Subsequent results were analyzed by using softwares concerning the periodical distribution,subjects' distribution,foundations,authors,institutes,journal types and key words.Results Overall 425 publications from 160 journals were included.The amount of the relevant articles showed an increasing trend in 2002 to 2012.The research in BCI in China was supported by a large amount of funds.There were a lot of Chinese authors and institutions participating in BCI study,and they were widely distributed across the country.However,only 32.56％ of all authors and 51.85％ of all institutions published more than 1 article.Moreover,research on BCI mainly was focused on the biomedical engineering aspect.Conclusions Research on BCI developed rapidly in the past 12 years in China and will continue to develop in the following decades.In the future studies,the focus should shift to clinical research instead of biomedical engineering,and to make this technology a useful clinical practice is the first priority.

ObjectiveTo evaluate the Chinese guidelines and consensus of rehabilitation medicine published in the medical journals in 2022 using Scientific, Transparent and Applicable Rankings (STAR). MethodsGuidelines and consensus which were developed by Chinese institutions or led by Chinese scholars were retrieved in databases of CNKI, Wanfang Data, CBM, Chinese Medical Journal Network, PubMed and Web of Science, in 2022, followed by screening for rehabilitation medicine field. The literature were rated with STAR. ResultsSeven guidelines and eleven consensuses were included. The STAR scores ranged from 11.7 to 69.6, with a median score of 25.9 and mean score of 28.3. There was a significant difference in the total score between guidelines and consensus (U = 12.000, P = 0.014). The score ratio was high in the domains of recommendations (73.6%), evidence (39.5%) and others (33.3%), while it was low in the domains of protocol (1.4%), clinical questions (12.5%) and conflicts of interest (13.9%). The score ratio was high in the items of listing the institutional affiliations of all individuals involved in developing the guideline (94.4%), identifying the references for evidence supporting the main recommendations (94.4%), indicating the considerations (e.g., adverse effects) in clinical practice when implementing the recommendations (88.9%), and making the recommendations clearly identifiable, e.g., in a table, or using enlarged or bold fonts (75%); and it was low in the items of describing the role of funder(s) in the guideline development (0), indicating information about the evaluation and management of conflicts of interest (0), providing tailored editions of the guidelines for different groups of target users (0), presenting the guideline or recommendations visually, such as with figures or videos (0), providing details of the guideline protocol (2.8%), assessing the risk of bias or methodological quality of the included studies (2.8%), describing the responsibilities of all individuals or sub-groups involved in developing the guideline (5.6%), indicating how the clinical questions were selected and sorted (5.6%), formating clinical questions in PICO or other formats (5.6%), making the guideline accessible through multiple platforms (5.6%), and declaring that the funder(s) did not influence the guideline's recommendations (8.3%). ConclusionThe quality of current clinical practice guidelines and consensus of rehabilitation medicine is poor, which should be developed in accordance with the relevant standards.

ObjectiveTo describe the medical services, quality and safety of rehabilitation medicine departments in general hospitals and rehabilitation hospitals in 2020 from the aspects of structure, link and outcome quality. MethodsThrough the National Clinical Improvement System of the National Health Commission, all secondary and above general hospitals and rehabilitation hospitals were investigated in 2021, the relevant data from 9 138 hospitals, including traditional Chinese Medicine hospitals and integrated traditional Chinese and Western medicine hospitals in 2020. A total of 2 676 sampling hospitals were equipped with rehabilitation medicine wards. After cleaning, a total of 2 268 samples of hospitals were included for analysis. Then, the setting of wards of rehabilitation medicine departments in 6 336 hospitals that participated in the questionnaire of rehabilitation medicine departments from 2017 to 2020 was analyzed. ResultsAmong the 9 138 general hospitals surveyed this year, only 2 676 had rehabilitation wards, and three general hospitals administrated to National Health Commision had not yet set up wards. In general hospitals, the average number of physicians per bed in 57.92% hospitals, the average number of rehabilitation therapists per bed in 80.44% hospitals, and the average number of nurses per bed in 53.92% hospitals did not meet the national requirements, and the average number of rehabilitation medical personnel per bed in rehabilitation medicine departments in different regions was significantly different. The rates of early rehabilitation intervention were 13.20%, 18.90% and 29.25% respectively in the department of orthopedics, department of neurology and department of intensive care in general hospitals. The average activity of daily living improvement rate of discharged patients from rehabilitation department of general hospital was 76.35%, and that of discharged patients from rehabilitation specialized hospital was 64.30%. ConclusionProfessional medical services and quality safety of rehabilitation medicine in China improve steadily, and the degree of homogenization is further strengthened. However, from the perspective of the current prominent problems, in 2020, most general hospitals in China have not configured the wards of rehabilitation medicine, and there are problems such as the total number of rehabilitation medical personnel in the country does not meet the requirements, uneven distribution, insufficient early intervention in rehabilitation, and room for improvement of rehabilitation treatment effect, which need continuous improvement.

ObjectiveTo analyze the medical services, quality and safety of rehabilitation medicine departments in general hospitals and rehabilitation hospitals in 2021 in perspectives of structure, segment and outcome quality. MethodsWe analyzed the data from National Clinical Improvement System of the National Health Commission, involving 9 328 hospitals, including all secondary and above general hospitals and rehabilitation hospitals, as well as traditional Chinese Medicine hospitals and integrated traditional Chinese and Western medicine hospitals in 2021. A total of 2 513 sampling hospitals that equipped with rehabilitation wards were included. ResultsAmong the 9 328 general hospitals surveyed this year, only 2 713 had rehabilitation wards. In general hospitals, the average number of physicians per bed in 56.77% hospitals, the average number of rehabilitation therapists per bed in 80.36% hospitals, and the average number of nurses per bed in 53.53% hospitals did not meet the national requirements, and the average number of rehabilitation medical personnel per bed in rehabilitation medicine departments in different regions was significantly different. The rates of early rehabilitation intervention were 13.45%, 20.67% and 29.74% respectively in department of orthopedics, department of neurology and intensive care units in general hospitals. The average improvement rate of activities of daily living of discharged patients was 77.87% in rehabilitation department of general hospitals, and 69.01% in rehabilitation hospitals. ConclusionIn 2021, professional medical services, quality and safety of rehabilitation medicine in China have improved steadily. However, most general hospitals in China still have not configured the rehabilitation wards, and there are problems such as the total number of rehabilitation medical personnel in the country does not meet the requirements, early rehabilitation intervention is significantly insufficient, and the implementation of important evaluation and therapies is deficient. The effect of rehabilitation still needs to improve. It is necessary to continuously promote capacity building of the medical rehabilitation to improve the quality of medical rehabilitation services.

ObjectiveTo investigate rehabilitation competence among trainers and trainees whom participated in the training program entitled National Training Program of Shortage Rehabilitation Physicians (NTPSRP) using World Health Organization rehabilitation competency framework (RCF). MethodsBased on RCF, a questionnaire was developed and administrated through network using Questionnaire Star. All the trainers and trainees who participated in NTPSRP were investigated in September, 2023. ResultsA total of 911 subjects were collected from 27 provinces, including 426 trainers (teachers) and 485 trainees (students). The average age of the teachers was older, with more years of work experience and professional experience in rehabilitation medicine. The degree and professional title of the teachers was also higher. The overall internal consistency reliability of the questionnaire was good (Cronbach's α = 0.988), and all the internal consistency reliability in five fields was good (Cronbach's α > 0.9). The five dimensional structure of RCF in the results was consistent with the prior model established by RCF theory. The self-ratings of all physicians in the five fields were higher than the median level, and was higher in the teachers than in the students [(3.42±0.68) vs. (2.73±0.80), P < 0.001]. Gender and years of experience in rehabilitation medicine were independent factors for the total score of the questionnaire. The total self-rating of female students was 9.65 points lower than that of the male (95%CI 4.386 to 14.914); and one more year in rehabilitation medicine would increase 1.78 points in self-rating (95%CI 1.140 to 2.419). ConclusionThe structure and content of RCF can be used to evaluate the competence of rehabilitation physicians. The teachers and students of NTPSRP are eligible to RCF. RCF-based evaluation can be used to guide the development of continuing education courses for rehabilitation professionals.

BACKGROUNDThe objective of this study was to analyze the trend in the publication of systematic reviews on hip fractures through a bibliometric approach.

METHODSLiterature including systematic reviews or meta-analyses on hip fractures was searched from the ISI Web of Science citation database. The search results were analyzed in terms of geographical authorship and frequency of citation by country, institution, author, and periodical distribution.

RESULTSA total of 654 published systematic reviews from 1995 to 2013 in 48 countries or regions were retrieved. The United States (171) was the predominant country in terms of the number of total publications, followed by the United Kingdom (149), Canada (120), Australia (76), and China (54). The number of systematic reviews significantly increased during the last 6 years, especially in China. The production ranking changed in 2012, at which time the United States and China were the leaders in the yearly production of systematic reviews on hip fractures. The amount of literature (27 publications) from China contributed almost one-quarter of the total literature (109 publications) in 2012. However, the average number of citations of each article from China was still low (6.70), while the highest number of citations of each article was from Sweden (193.36). The references were published in 239 different journals, with 15 journals contributing to 41.3% of the systematic reviews on hip fractures. The two journals that contributed the most were Osteoporosis International (10.6%) and the Cochrane Database of Systematic Reviews (7.6%). The predominant institution in terms of the number of publications was McMaster University (36) in Canada.

CONCLUSIONSThe best evidence in the field of hip fractures has attracted increasing attention. Systematic reviews on hip fractures from China have been increasingly more frequent during the past 6 years, particularly in 2012.
