The response time and accuracy of inhibition, conversion, and refresh functions decreased in the observation group (t > 2.259, P < 0.05), and were lower than that of the control group (t > 2.007, P < 0.05). Conclusion Aerobic exercise could reduce the core symptoms of poor attention and hyperactivity impulsivity, and improve the executive functioning in children with ADHD.

Objective To explore the psychological and behavioral characteristics of understanding Chinese garden path sentences in children with high-functioning autism (HFA). Methods From April to August, 2019, 35 children with HFA and 35 age-matched typically developing (TD) children were recruited by social recruitment method in the Key Laboratory of Speech and Hearing of East China Normal University in Shanghai. The Garden Path Sentence Comprehension Test was designed based on the psycholinguistic method, and the mental process and the ability of understanding garden path sentences were tested by the agent task experiment paradigm. Finally, the processing strategies and error types of Chinese spoken garden path sentences for HFA children were explored. Results The score in understanding garden path sentences was lower (t = -2.941, P < 0.01), and the reaction time in processing garden path sentences was significantly longer (t = 6.132, P < 0.001) in HFA children than in TD children, however, there was no significant difference in the number of childern mastering garden path sentences between two groups (χ² = 2.954, P > 0.05). In terms of the error types of "animate noun + verb + animate noun + 's + noun" (AVA) and "animate noun + verb + inanimate noun + 's + noun" (AVI) garden path sentences, both groups showed more errors in "pursuit of correct word order" than in "pursuit of semantically correct" (t > 2.503, P < 0.05). In "inanimate noun + verb + animate noun + 's + noun" (IVA) sentences, HFA children showed less erros in "pursuit of correct word order" than in "pursuit of semantically correct" (t = -6.523, P < 0.001), however, no difference was found between them in TD children (t = 2.024, P > 0.05). Conclusion The processing and comprehension ability of Chinese spoken garden path sentences in HFA children aged five to seven yeas are poor. HFA children are more sensitive to semantics, and garden path sentences with semantic violations are more likely to lead to HFA children's understanding errors. In the garden path sentence patterns of AVA and AVI, HFA children appear similar sentence understanding and processing strategies as TD children. In the garden path of IVA, HFA children use a sentence processing strategy combining word order and semantics, but semantics play a more prominent role, while TD children use a more stable word order processing strategy.

Diastasis recti abdominis (DRA) is common in postpartum women. DRA seriously affects the physiological and psychological health of patients. Rehabilitation is the main intervention for DRA.

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 develop a scale for assessment of communication functions in children's daily life.

Methods Based on the International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY) communication function-related categories, test items applicable to children's communication function were developed through a structured interview method and linguistic analysis. Delphi method was used to evaluate and select the items. The items were tested by item analysis and exploratory factor analysis to construct the scale structure. The internal consistency reliability, split-half reliability, structural validity, and criterion-related validity of the scales were tested by 168 children through internet.

Results A children's communication function scale consisting of 42 items was developed, involving four subtests, including preverbal communication (8 items), simple oral communication (5 items), comprehensive oral communication (20 items), and pictorial symbolic communication (9 items). The scale was tested with moderately difficult and high discrimination (0.328 to 0.936). The scale had good internal consistency reliability (0.897 to 0.979) and split-half reliability (0.851 to 0.952), as well as structural validity (r = 0.536 to 0.836). The total scale score was correlated with the Peabody Picture Vocabulary Test-Revised validity scale (r= 0.787, P< 0.05).

Conclusion The ICF-CY-based scale of communication functions in children's daily life consisted of 42 items in four subtests. It has shown good consistency reliability, split half reliability, construct validity and criterion-related validity.

Objective To analyze the content and psychological measurement indicators of the commonly used motor function assessment tools for children and adolescents, based on the theory and method of International Classification of Function, Disability and Health-Children and Youth Version (ICF-CY). Methods Based on the ICF-CY classification framework and coding system, four commonly used functional evaluation tools for children and adolescents were selected, and their motor function measurement methods and psychological measurement indicators were analyzed by applying ICF coding rules and matching principles. Results Finally, nine English articles and two Chinese articles were included, from four countries including South Korea, Spain, China and Brazil. They were mainly published in the journals of clinical medicine, neuroscience, public health, rehabilitation science and other fields from 2011 to 2021. The age of the subjects was 0 to 16 years old involving 987 subjects; the health condition included spastic cerebral palsy, neurodevelopmental disorder, etc. Among the eleven articles included, six articles used Gross Motor Function Measure (GMFM-88), two articles used Fine Motor Function Measure Scale (FMFM), two articles used Peabody Developmental Motor Scales Second Edition (PDMS-2), and two articles used Pediatric Evaluation of Disability Inventory-Functional Skills Scale (PEDI-FSS), and three articles used Pediatric Evaluation of Disability Inventory (PEDI). The measurement methods were objective evaluation, subjective evaluation, and subjective observation, etc. The number of measurements was two to six. The measurement indicators of motor function mainly involved two levels. The first was the physical activity level, including gross movement, fine movement and motor control ability. The second was the functional level of activities, mainly including activities of daily living and functional independence. Conclusion Based on ICF-CY, the evaluation of children's motor function and activity and participation was mainly divided into two levels. At the body function level, the main evaluation indicators included b730, b760, b770, etc. At the level of activities and participation, the main evaluation indicators were d410, d440, d445, etc. GMFM-88 focuses on the evaluation of children's body movement and activity functions, such as sitting, standing, lying, walking and running, mainly involving b760, d410, d455, etc. FMFM focused on autonomous movement, motor motivation and motor coordination, and was mainly used to assess the functional status of upper limbs of children with cerebral palsy aged 0 to 3 years, mainly involving b760, d155, d440, etc. PDMS-2 payed more attention to evaluating the overall motor development level and motor function status of children and adolescents, mainly involving b750, b760, d415, etc. PEDI-FSS move partition focused on children's actual motor function performance in activities of daily living, and evaluated the application and practicability of children's motor function in activities of daily living, mainly involving b760, d410, d450, etc. In terms of measurement methods, the measurement of motor function mainly included objective evaluation and subjective evaluation; the measurement of activity function mainly included objective evaluation and subjective observation. These assessment tools have established norms varies with different age groups according to the movement development. Evaluators need accept professional training before using the above assessment tools to improve the reliability, validity and adaptability of the assessment.
