目的 探讨童趣化视频联合回授法在学龄前期肱骨骨折术后患儿功能锻炼健康教育中的应用效果。 方法 采用便利抽样法，选取2024年1月—6月在浙江大学医学院附属儿童医院骨科创伤中心就诊的156例4~6岁肱骨骨折术后患儿作为研究对象。其中2024年1月—3月就诊的80例患儿作为对照组，2024年4月—6月就诊的76例患儿作为试验组。对照组接受常规功能锻炼健康教育，试验组接受基于童趣化视频联合回授法的功能锻炼健康教育。比较两组入院和出院时的儿童应激障碍检查表中文版得分、术后6个月肘关节Mayo功能评分及术后1个月内功能锻炼依从程度。 结果 试验组患儿出院时儿童应激障碍检查表中文版总得分及各维度得分均低于对照组，术后6个月肘关节Mayo功能评分高于对照组、术后1个月内功能锻炼依从程度高于对照组（均P<0.05）。 结论 童趣化视频联合回授法在学龄前期肱骨骨折术后患儿功能锻炼健康教育中的应用能改善其应激反应症状的程度、肘关节功能、功能锻炼依从性，值得推广。

Objective To explore the application effect of child-friendly video combined with the teach-back method in functional exercise education for preschool children after humeral fracture surgery. Methods A convenience sampling method was used to select 156 children aged 4-6 years who underwent humeral fracture surgery in Orthopedic Trauma Center of Children’s Hospital Affiliated to Zhejiang University School of Medicine between January and June 2024. Participants treated from January to March 2024（n=80） were assigned to the control group receiving routine health education on functional exercise，while those treated from April to June 2024（n=76） classified to the experimental group receiving health education on functional exercise using child-friendly videos combined with the teach-back method. The Chinese version of the Child Stress Disorders Checklist （CSDC） was assessed at admission and discharge，Mayo elbow function was evaluted at 6 months post-surgery，and compliance with functional exercise within 1 month post-surgery were compared between the two groups. Results At discharge，the experimental group demonstrated significantly lower total and subscale scores on the CSDC-Chinese version compared to the control group（all P<0.05）. Additionally，the experimental group achieved higher Mayo elbow function scores at 6 months post-surgery and greater compliance with functional exercise within 1 month post-surgery than the control group（all P<0.05）. Conclusion The integration of child-friendly videos and the teach-back method in health education for preschool children after humeral fracture surgery can effectively reduce stress response symptoms，improve elbow functional recovery，and enhance compliance with rehabilitation exercises. This approach is worthy of wider application in clinical practice.
