摘要

儿童言语失用症（childhood apraxia of speech，CAS）是由神经系统发育性损伤引发的儿童期言语运动障碍，其核心病理特征为言语运动计划与编程功能缺陷，使患儿无法精准完成言语相关肌肉的协调运动，进而出现言语发声、音节组合及声调控制等多重障碍。该障碍会持续损害儿童言语清晰度与沟通可懂度，阻碍其语言表达能力发展，还会对其日常社交互动、学业发展乃至心理健康造成长远的负面影响，降低患儿生活质量，给家庭与社会带来负担。自上世纪中叶以来，CAS已成为国际言语病理学领域的重点研究方向，经过数十年深入探索，在病因病理机制、标准化诊断标准、精准评估工具及循证干预方案等维度积累了大量临床研究数据与实践成果，形成了完善的研究与临床应用体系。我国针对CAS的临床诊疗与科学研究仍处于初步探索阶段，临床诊断普遍存在认知不足、筛查流程不规范、确诊率偏低等问题，同时缺乏针对汉语儿童的特异性干预方案，临床干预多借鉴国外模式，本土化循证依据匮乏，难以满足国内患儿的诊疗需求。为全面引进国际前沿研究成果与临床经验，弥补国内相关研究短板，助力构建符合汉语儿童语言特点的本土化CAS诊断与干预体系，本文系统梳理国外CAS研究进展，从病因与神经机制、临床核心识别特征、标准化评估体系、循证干预策略及面临的挑战等方面展开综述，为国内言语康复临床工作者、相关领域研究者提供科学、实用的参考依据，推动我国CAS诊疗与研究工作规范化、专业化发展。

Abstract

Childhood apraxia of speech (CAS) is a developmental speech motor disorder caused by neurological developmental impairment. Its core feature lies in deficits in speech motor planning and programming. Children with CAS are unable to precisely coordinate speech-related muscle movements

resulting in impairments in phonation

syllable sequencing

and tone control. No only does this disorder hinder the development of expressive language

but also exerts profound and lasting adverse effects on daily social interaction

academic learning

and mental health

greatly reducing children's quality of life and imposing a burden on families and society.Since the mid-20th century

CAS has become a research hotspot in the field of international speech-language pathology. Decades of in-depth research have yielded systematic clinical evidence and practical achievements in multiple dimensions

including etiological and neural mechanisms

standardized diagnostic criteria

precise assessment tools

and evidence-based intervention protocols

forming a relatively mature research and clinical application system. In contrast

the clinical diagnosis and scientific research of CAS in China are still at an initial stage. Common problems include insufficient clinical awareness

non-standardized screening procedures

and low diagnostic rates. Moreover

specific intervention programs tailored to Chinese-speaking children are scarce. Most clinical interventions are directly adopted from foreign models without necessary localization

resulting in a severe lack of evidence-based foundations tailored to Chinese-speaking children

thus failing to meet their clinical needs.To introduce international cutting-edge research and clinical experience

address current research deficiencies in China

and facilitate the establishment of a localized diagnosis and intervention system tailored to the linguistic characteristics of Chinese-speaking children

this paper systematically reviews overseas research progress on CAS. It elaborates on etiology and neural mechanisms

core clinical characteristics

standardized assessment systems

evidence-based intervention strategies

and current research challenges and future directions. The aim is to provide scientific and practical references for clinical practitioners and researchers in the field of speech-language rehabilitation

and to promote the standardized and professional development of CAS diagnosis

intervention

and research in China.
