Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Studies have shown that children with ASD simultaneously have deficits in overall executive function and impairments in basic motor skills, which have a negative impact on cognitive and social all-round development. In recent years, intervention measures for the motor skills of children with ASD have gradually developed. However, based on the existing literature, there is still a lack of recommendations for sports training at present. The sustained effect of exercise intervention training on the core symptoms of ASD remains unclear. In terms of executive function, there are relatively few studies on the executive function of preschool children. The impact of motor training on working memory in school-aged children is still inconsistent. Furthermore, the connection characteristics of different brain regions in children with ASD after physical training remain unclear. This study will include 70 children with ASD aged 3 to 9 years for a multicenter randomized controlled trial (RCT). These children will be randomly assigned to the intervention group (Child-Parent-Trainer program) and the control group (regular physical education program) for 12 weeks, 5 days/week, 60 minutes/day training. Children's core symptoms, executive function, child/family quality of life, and functional near-infrared spectroscopy (fNIRS) were assessed at baseline (training weeks 0) and endpoints (training weeks 13 and 17), respectively. To verify the improvement effect of this exercise program on the autism severity, core symptoms and executive functions of children with ASD, as well as its impact on family quality of life. Furthermore, through fNIRS for monitoring changes in brain function, the potential neural physiological mechanisms will be explored.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. Procedures. The children in the group are randomly divided into a intervention group and a control group. The children will be trained for 12 weeks (5 days/week, 60 minutes/day) and the children will be evaluated for the severity of autism, core symptoms, executive function, child/family quality of life, and fNIRS at training weeks 0, 13, and 17, respectively.
2. Demographic questionnaire and clinical data. The demographic questionnaire is completed by the child's primary caregiver, detailing child's name, gender, date of birth, height, weight, heart rate. Clinical data will be ascertained from the medical records, including information about DSM-5 diagnosis and comorbid conditions.
3. Sample size. This study is a randomized controlled trial. The proposed sample size is based on using the sample size formula, which compares the two sample means, . Where, tα is the standard normal difference corresponding to the level, taking α=0.05 and tα=1.96; tβ is the u value corresponding to the probability β of type II error, taking β=0.10 and tβ=1.28; σ is the estimate of the population standard deviation; δ is the allowable error, the difference between two population means. According to literature review, taking the adjustment ability in executive function as the main observation index, it is calculated that δ/σ =0.84. The sample size of intervention group and control group was 30 children, respectively. Considering the sample loss rate of 15%, the two groups are finally determined to be 35 children respectively.
4. Statistical analysis. SPSS 25.0 software (SPSS Inc) was used for statistical analysis for the scale data, including core symptoms and executive function, and the data were expressed as (M±SD). The scales scores and demographic variables of both groups of children will be compared using independent samples t-tests. Differences between baseline and 1 week and 1 month after exercise will be analysed using a repeated measures F-test. All statistical analyses were conducted with a statistical threshold P-value of \<0.05. The data collected through fNIRS will be performed via NirSpark analysis software. The general linear model (GLM) will be applied to integrate task effects and assess activation in relevant brain regions. To analyze the rsFC of brain in children with ASD before and after the exercise intervention, the FC\_NIRS toolbox is used.
5. Ethical matters and data protection. The patients participated in the study will sign the informed consent (obtained from the guardian). And this study was approved by the local ethics committee. Patient's name will be abbreviated and the research data will be assigned a code then to provide to the researcher. The authorization from parents on the patient's health information remains valid until the study is completed. After that, researchers will delete private information from the study record.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group

The intervention group received systematic exercise training (the Child-Parent- Trainer exercise program) for 12 weeks (5 days/week, 60 minutes/day).

Group Type EXPERIMENTAL

The Child-Parent- Trainer exercise program

Intervention Type PROCEDURE

The Child-Parent-Trainer exercise program is a 12-week exercise training program, which is based on the sensory and cognitive needs of children with ASD, multiple game forms are integrated to form a multi-sensory intervention model. The exercise program is developed according to the types of exercise recommended in the Exercise Guidelines for Preschool Children of China, including the development of basic motor skills, such as physical movement, posture control, object control; development of important physical qualities, such as agility, balance, coordination. The training program for different age group consists of physical movement items, object control items and limb coordination items. The exercise intensity is moderate.

Control group

The control group received regular physical training courses for 12 weeks (5 days/week, 60 minutes/day).

Group Type ACTIVE_COMPARATOR

The regular physical training

Intervention Type PROCEDURE

The regular physical training courses will last for 12 weeks. It is training in motor skills and fine motor skills. The items include passing the ball, lifting small dumbbells, running, handicrafts, etc. There is no requirement for the intensity of the exercise.
