Objective To systematically review the effects of the early childhood physical activity program (ECPAP) on gross motor skill (GMS) in preschool children. Methods We searched Web of Science, PubMed, Cochrane Library, EBSCO SPORTDiscus with Full Text, CNKI, WanFangData and VIP databases to collect randomized controlled trails (RCT) about ECPAP for improving GMS in preschool children from the establishment of the database to August 8, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4.1 and Stata 15.0 software. Results A total of 18 studies including 1 141 children in experimental group and 1 135 children in control group were included. The results of meta-analysis showed that after ECPAP, the GMS (SMD=1.96, 95%CI 1.44 to 2.49), locomotor skills (SMD=1.15, 95%CI 0.83 to 1.46) and manipulative skills (SMD=1.25, 95%CI 0.84 to 1.65) of the experimental group were significantly better than those of the control group (P<0.05). Conclusion ECPAC is considered to significantly promote the GMS of preschool children. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To evaluate the application of the Huaxi Intelligent Endoscopic Skill Training and Assessment System in minimally invasive surgery (MIS) skills training and provide insights for optimizing MIS training models, we analyze trainee performance during training and assessment. Methods A retrospective analysis was conducted on the use of this system across 28 medical institutions from January 2022 to January 2025. Results By January 2025, the standardized deployment of 139 simulation units had been completed. A total of 403 trainees from various surgical specialties, including thoracic surgery and general surgery, participated in five customized endoscopic skill training modules: endoscopic recognition, grasping training, positioning and placement, cutting training, and suturing training. Throughout the training period, a total of 78 participants took part in 27 formal assessments. Correlation analysis based on Spearman showed that pre-assessment training pass rates were significantly correlated with final assessment scores, indicating enhancing the quality of each training module and overall training efficacy is a key to improving the effectiveness of MIS training. Conclusion The Huaxi Intelligent Endoscopic Skill Training and Assessment System effectively supports MIS training and evaluation.
