Abstract: Objective To investigate the etiology and pathology of functional articulation disorder (FAD) by minimal phoneme contrast test in children with FAD. Methoods One hundred FAD children and one hundred typical children matched for ages were selected as testees.The auditory recognition abilities were examined by Minimal Phoneme Recognition Scale in a quiet room.Intelligence and language developments were evaluated in test groups. Results The recognition abilities of Consonant Phoneme Contrast (CPC),Vowel Phoneme Contrast (VPC) and the subtests in FAD children were all much inferior to typical children (P<0.05).There was a negative correlation between the recognition abilities of all tests and impairments in FAD children,except the type of CPC described as "the same manner with different places",the VPC of retroflex and unretroflex and the VPC of front nasal and back nasal; Except the CPC of fricatve and unfricative (P>0.05),the recognition abilities of CPC,VPC and the other subtests in FAD with language impairment (n=36) were all much inferior to FAD (n=64) (P<0.05).Twenty-nine patients were moderate to severe disorder in FAD with language impairment (80.56%). Conclusion The recognition abilities of Phoneme Contrast (PC) in FAD children are much inferior to typical children,which might contribute to FAD.

摘要： 目的 研究功能性构音障碍(functional articulation disorder,FAD)儿童的音位对比式言语识别能力,以探讨其病因及发病机制。方法 选择符合FAD诊断标准的儿童及同年龄段正常儿童各100例作为被试,采用《儿童音位对比式识别能力评估(孙喜斌-刘巧云词表)》在安静房间中进行听觉识别能力评估,并对其分别进行智力及语言发育水平测定。结果 FAD儿童的声母、韵母及各项分测试识别能力均低于对照组,且差异有统计学意义(P<0.05)。除相同方式不同部位、卷舌音与非卷舌音、前鼻韵母与后鼻韵母外,FAD儿童的各项识别能力得分与构音障碍程度呈负相关。擦音与无擦音测试中,伴有语言发育迟缓的FAD儿童(36例)的识别能力低于单纯FAD儿童(64例),但差异无统计学意义(P>0.05);其余各项测试中,伴有语言发育迟缓的FAD儿童的识别能力低于单纯FAD儿童,且差异有统计学意义(P<0.05)。且伴语言发育迟缓的FAD儿童中中重度构音障碍者占80.56%。结论 FAD儿童的音位对比式言语识别能力明显落后于正常儿童,音位识别能力落后可能为FAD病因之一。
