Objective To 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.
Methods The 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.
Results A 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.
Conclusion Research related to the field of PFD rehabilitation is increasing. There is still a large gap for future development in China.

Objective To observe the effect of music therapy on cognitive function, motor function, and activities of daily living (ADL) of patients with post-stroke cognitive impairment.
Methods From December, 2020 to July, 2022, 48 patients with post-stroke cognitive impairment in Beijing Bo'ai Hospital were enrolled and randomly divided into control group (n = 24) and experimental group (n = 24). Both groups received conventional medication, nursing, and conventional rehabilitation, while the experimental group received music therapy additionally, for eight weeks. Before and after intervention, the cognitive function was assessed by Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), and motor function and ADL were assessed with Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI), respectively.
Results Six cases in the control group dropped down. The increase in the scores of LOTCA and FMA was more in the experimental group than in the control group (t > 2.665, P < 0.05), however, no significant difference was found in the increase of MBI score between two groups.
Conclusion Music therapy could improve the cognitive function and motor function of patients with post-stroke cognitive impairment.

Objective To synthesize the structure, content and psychometric properties of physical activity measurement/reporting tools applied in children and adolescents with disabilities.
Methods Literature on physical activity measurement/reporting tools for children with disabilities were retrieved from PubMed, Medline, EBSCO, Web of Science and CNKI, from establishment to June, 2023. The main structure and content characteristics of the tools were analyzed using the International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY). The psychometric properties of the tools was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN).
Results Six tools were selected, and nine papers were finally included. Two tools were globalized standard tools, namely Global Matrix 4.0 Physical Activity Report Card for Children and Youth (Global Matrix 4.0) and the Global Matrix of Para Report Card on Physical Activity of Children and Adolescents with Disabilities (Para Report Card), measuring b455 functions of motor tolerance function, b7 neuromusculoskeletal and motor-related functions; d4 mobility, d450 walking, d470 using transportation, d820 school education, d910 community life, d920 recreation and leisure; e310 immediate family, e320 friends, e460 societal attitudes, and e575general social support services, systems and policies, etc. These tools showed a complete structure, high reliability, validity and feasibility, and could be performed in a self-reported manner or completed by the custodian or school teacher. The International Physical Activity Questionnaire (IPAQ) might measure d4 mobility, d450 walking, d640 doing housework, d820 school education, d920 recreation and leisure. IPAQ was good in terms of internal consistency, content and construct validity, and cross-cultural validity, with different test-retest reliability and hypothesis testing results reported in different applied studies. Children and Adolescents Physical Activity and Sedentary-Questionnaire (CAPAS-Q) might measure the d4 mobility, d450 walking, d470 using transportation, d820 school education, and d920 recreation and leisure. CAPAS-Q was good in internal consistency, retest reliability, content and construct validity, but hypothesis testing results and cross-cultural validity were unknown. Physical Activity Questionnaire for Older Children (PAQ-C) and Physical Activity Questionnaire for Adolescents (PAQ-A) might measure d4 mobility, d450 walking, d470 using transportation, d820 school education, and d920 recreation and leisure. PAQ-C and PAQ-A were strong in internal consistency, retest reliability, content and construct validity, and cross-cultural validity, without hypothesis testing results.
Conclusion In terms of content, Para Report Card is the most comprehensive and extended physical activity measurement/reporting tool for children and adolescents with disabilities. In terms of the psychometric properties of the instruments, the multidimensional, structured physical activity measures show high internal consistency, retest reliability, and content and construct validity, with varying retest reliability and correlational validity with objective measures across studies.

Objective To explore sleep disturbance in preschool children with autism spectrum disorder (ASD) and analyze the relationship between sleep disturbance and social behavior.

Methods From December, 2020 to December, 2022, 221 preschool children with ASD from Beijing Bo'ai Hospital and other two institutes, and 246 healthy preschool children socially recruited were investigated with Children's Sleep Habits Questionnaire (CSHQ). A total of 47 ASD children and 47 healthy children were selected from them to wear a sleep monitoring watch for seven days, while the ASD children were evaluated with Gesell Development Diagnosis Scale (GDDS), Psychoeducational Profile-Third Edition (PEP-3), Autism Diagnostic Observation Schedule-2 (ADOS), Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS) and Social Responsiveness Scale (SRS).

Results All the factor-scores were more in the ASD children than in the healthy children (t > 2.491, P < 0.05), except that of daytime sleepiness. The prevalence of sleep disturbance (CSHQ ≥ 41) was 89.6% in ASD children, which was more than that of the healthy children (76.8%) (χ² = 13.360, P < 0.001). The sleep problems in ASD children included bedtime resistance, sleep anxiety, sleep duration, sleep onset delay, parasomnias and sleep disordered breathing. ASD children were shorter in total bedtime, shorter in total sleep time, longer in sleep latency, longer in awake time and lower in sleep efficiency (|t| > 2.001, P < 0.05), compared with those of healthy children. For ASD children, the total bedtime negatively correlated with GDDS-language, PEP-3-expressive language, PEP-3-communication and PEP-3-maladaptive behaviors (r < -0.300, P < 0.05); the sleep efficiency negatively correlated with total score of CARS (r = -0.365, P < 0.05); sleep latency correlated with GDDS-social, PEP-3-cognitive, PEP-3-expressive language, PEP-3-receptive language, PEP-3-visual-motor imitation, PEP-3-characteristic verbal behaviors, PEP-3-communication, original score of ADOS, ADOS-social affect, and total score of CARS (|r| > 2.90, P < 0.05); and total awake time positively correlated with total score of CARS (r = 0.406, P < 0.05).

Conclusion Sleep disturbance is prevalent and various in preschool ASD children, and influence their social behaviors.

Objective To evaluate the main structural and content features of four instruments for motor function and motor ability assessment and their psychometric properties for children and adolescents with disabilities, based on International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY).
Methods PubMed, Medline and Web of Science databases were searched for literature on motor function and motor ability assessment for children and adolescents with disabilities published from establishment to May, 2023. The main structural and content characteristics of the tools were analyzed using ICF-CY, and the quality of measurement tools was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN).
Results Nine papers were eventually included, and four assessment tools were identified, including Gross Motor Function Measure-88 (GMFM-88), Peabody Developmental Motor Scales second edition (PDMS-2), Bruininks-Oseretsky Test of Motor Proficiency second edition (BOT-2), and Movement Assessment Battery for Children second edition (MABC-2). The GMFM-88 consisted of 88 items in five dimensions: zone A (lying and rolling), zone B (sitting), zone C (crawling and kneeling), zone D (standing), and zone E (walking and running and jumping); it involved joint movement function (b710), random movement control function (b760), etc., in body function; and the change of basic body posture to maintain a body posture (d410) and maintain a body posture (d415) in activity and participation, with good to excellent levels of internal consistency reliability, test-retest reliability, content validity, and structural validity. The PDMS-2 consisted of six subtests, including reflexes, posture, movement, physical manipulation, grasping and visuomotor integration, with a total of 249 items; it involved memory function (b144) and joint mobility function (b710) in body function; as well as looking (d110) and imitation (d130) in activity and participation; with good psychometric properties in terms of internal consistency reliability, test-retest reliability, content validity, structural validity, and hypothesis testing and cross-cultural feasibility. There are two versions of BOT-2: long form and short form. The long form consisted of eight subtests with 53 items, involving joint mobility function (b710) and joint stability function (b715) in body function; as well as imitation (d130) and learned calculation (d150) in activity and participation; it achieved excellent levels of psychometric properties in terms of internal consistency reliability, content validity, and structural validity, and good level in reliability and test-retest reliability. MABC-2 consisted of two parts: an activity ability test and a checklist with 30 items; it involved joint mobility function (b710), joint stability function (b715), etc., in body function; as well as fine-hand use (d440), hand and arm use (d445) in activity and participation; with good psychometric properties such as reliability, content validity, and structural validity.
Conclusion This systematic review analyzed the main structural and content characteristics of four types of measurement tools for assessing motor function and motor ability in children and adolescents with disabilities based on the ICF-CY, and evaluated the quality of psychometric properties (internal consistency reliability, test-retest reliability, content validity, structural validity, and cross-cultural consistency, etc.) of the four types of measurement tools using the COSMIN criteria. For the structure and content, PDMS-2 appears the broadest content, and measures fine hand movements, dynamic and static balance, along with the BOT-2 and MABC-2. GMFM-88 focuses more on gross motor functions such as postural control. Four instruments show high internal consistency reliability, test-retest reliability, content validity and structural validity, while the BOT-2 and PDMS-2 show better reliability. To ensure the reliability and validity of the measures, rehabilitation workers and educators need to receive standardized training and qualification before using the standardized instruments for motor function and motor ability for children with disabilities. With norm-referenced measures, the results need to be converted to standard scores.

Methods From January to December, 2022, 60 stroke patients from Zhejiang Provincial People's Hospital were randomly divided into atDCS group (n = 20), CCFES group (n = 20) and combined group (n = 20). All the groups accepted routine rehabilitation, while atDCS group accepted atDCS on the primary motor (M1) area of the damaged hemisphere, CCFES group accepted CCFES on the triceps brachii and extensors carpi muscles, and the combined group accepted atDCS on the M1 area of damaged hemisphere and CCFES on triceps brachii and extensors carpi muscles, for six weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), and the electromyography root mean square (RMS) ratio of bilateral triceps brachii muscles and extensor carpi muscles, before and after treatment.

Results The FMA-UE score, WMFT score, and the RMS ratio of the triceps brachii muscles and extensor carpi muscles improved in all the groups after treatment (|t| > 5.007, P< 0.001), and improved the most in the combined group (F> 14.492, P < 0.001).

Conclusion atDCS combined with CCFES can effectively improve upper limb motor function of stroke patients.

Objective To explore the weights and comprehensive indices of each field of intrinsic capacity of old adults, and the correlation between intrinsic capacity and activities of daily living (ADL).
Methods The data of 5 506 cases aged more than 60 years in the 2015 China Health and Retirement Longitudinal Study (CHARLS) were used to collect the assessment of intrinsic capacity and the measurement of ADL. The assessment of intrinsic capacity included cognition, motor, vitality, sensory and psychology; while the ADL scale included six indicators, namely dressing, bathing, eating, getting in or out of bed, going to the toilet, and controlling urine and feces.
Results A total of 1 343 cases were limited in ADL (24.4%). Women, lower education level, older age, the widowed, greater number of chronic diseases, and poorer self-rated health were the factors more likely to be limited in ADL. Principal component analysis showed that the largest weight value was in psychological domain, followed by the cognitive domain, and the lowest weight value was in the motor domain. After controlling for the effects of age, gender, living environment, economic income, education level, marriage, smoking and drinking, number of chronic diseases, and self-rated health, the Logistic regression analysis showed that low exercise capacity (OR = 0.581, 95%CI 0.501 to 0.674), depression (OR = 0.426, 95%CI 0.368 to 0.493), audile and visual impairment (OR = 0.813, 95%CI 0.699 to 0.947; OR = 0.684, 95%CI 0.578 to 0.809), overweight (OR = 1.203, 95%CI 1.014 to 1.428) and obesity (OR = 1.584, 95%CI 1.312 to 1.912) were independent risk factors for ADL limitation in older adults.
Conclusion Decrease of intrinsic capacity is a predictor for ADL limitation in older adults.

Objective To explore the current status and frontier hotspots of functional near-infrared spectroscopy (fNIRS) in the field of stroke.

Methods Relevant 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.

Results A 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.

Conclusion Researches 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.

Objective To understand the current research status, research hotspots and development trends of constraint-induced movement therapy (CIMT) in the field of rehabilitation.

Methods The 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.

Results A 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.
