重复刻板行为是孤独症谱系障碍患者最具特征性的行为，其病因复杂，临床表现高度异质且受多种因素（睡眠质量以及胃肠健康、年龄性别等）影响，缺乏明确的诊断标准，目前临床干预效果也甚微。本文主要对近年来孤独症重复刻板行为相关临床研究进行梳理，探讨其诊治相关研究进展与面临的挑战，以期为未来的临床诊治工作提供新的思路。

Restricted repetitive behaviors (RRBs) are the most characteristic behaviors of autism spectrum disorder. The clinical diagnosis and treatment of RRBs are extremely difficult resulting from its complex and variable etiology, highly heterogeneous clinical manifestations influenced by multiple factors (sleep quality, gastrointestinal health, age and gender), lack of precise diagnostic criteria and low effectiveness of current clinical interventions. This article mainly reviews the recent related studies on RRBs and discusses the challenges and progress in clinical diagnosis and treatment of RRBs so as to provide new ideas for future clinical diagnosis and treatment.
