Abstract: Objective To explore the oral sensory-motor function and its correlation with consonant pronunciation errors in children with functional articulation disorders (FAD), in order to provide basis and ideas for intervention in FAD children. Methods A total of 61 FAD children admitted to the Department of Child Health in Qingdao University Affiliated Hospital from June 2021 to January 2022 were selected as the case group, and 90 normal healthy children were enrolled into the control group. Speech disorder examination, articulatory organ, hearing examination and oral sensory-motor assessment were performed in children to analyze the correlation between consonant mispronunciation and oral sensory-motor function. Results Compared with those of control group, the total score of oral sensory-motor function (0.85±0.08 vs.0.94±0.03), oral sensation (0.96±0.08 vs.1.00±0.00), mandibular movement (0.80±0.15 vs.0.91±0.05), lip movement (0.86±0.09 vs.0.93±0.04) and tongue movement (0.82±0.12 vs.0.94±0.03) of children in the case group were significantly lower (t=10.307,4.471,6.595,5.865,9.626, P<0.001). There were correlations of bilabial and mid-lingual sounds with the movements of the tongue and jaw (P<0.05), and correlations between labiodental sounds and movements of jaw and lip part (P<0.05), between lingual and tongue part movements (P<0.05). Moreover, correlations ofprelingual, postlingual and lingual root sounds with jaw, tongue and lip part movements were significant (P<0.05). Conclusion Oral sensory-motor function in children with FAD is low, and is correlated with consonant mispronunciation to varying degrees.

摘要： 目的 探究功能性构音障碍(FAD)儿童口部感觉-运动功能及其与辅音发音错误相关性,为FAD干预提供依据和思路。方法 选取2021年6月—2022年1月于青岛大学附属医院儿童保健科FAD儿童61例为病例组,正常健康儿童90例为对照组。对两组儿童进行构音障碍检查、构音器官、听力检查以及口部感觉-运动评估,比较辅音发音错误与口部感觉-运动功能相关性。结果 病例组儿童的口部感觉-运动功能总分(0.85±0.08 vs.0.94±0.03)、口部感觉(0.96±0.08 vs.1.00±0.00)、下颌运动(0.80±0.15 vs.0.91±0.05)、唇运动(0.86±0.09 vs.0.93±0.04)、舌运动(0.82±0.12 vs.0.94±0.03)均值均低于对照组,差异具有统计学意义(t=10.307,4.471,6.595,5.865,9.626,P<0.001);双唇音、舌尖中音与下颌、舌部分运动之间有相关性(P<0.05),唇齿音与下颌、唇部分运动之间有相关性(P<0.05),舌面音与舌部分运动之间有相关性(P<0.05),舌尖前音、舌尖后音、舌根音与下颌、舌、唇部分运动之间有相关性(P<0.05)。结论 FAD儿童口部感觉-运动功能低下,且与辅音发音错误数量呈现不同程度的相关性。
