Abstract: Objective To explore the phonological characteristics and rehabilitation training efficacy of abnormal lingua-palatal phoneme in patients with functional articulation disorders (FAD). Methods Totally 120 children with FAD were enrolled from February 2016 to February 2017 and received rehabilitation training. The training efficacy and the correlation between abnormal lingua-palatal phoneme articulation and age were analyzed. Results The articulation disorder of /j/ mainly showed being replaced by /x/,/d/, lateral misarticulation or omission;/q/ mainly showed replacement by/j/,/x/,/t/ or lateral misarticulation; /x/ mainly showed replacement by/j/ or lateral misarticulation. The common erroneous articulation forms of /j/,/q/, /x/ were replacement and lateral misarticulation.Finally, 104 cases were cured and 13 cases improved after 3~6 weeks of rehabilitation, and the overall cure rate was 86.67% (104/120). The cure rates of mild, moderate and severe disorder were 100% (7/7), 82.61% (19/23) and 86.67 % (78/90) respectively. The number of erroneous wordssignificantly decreased from 23.11±9.41 to 1.85±6.17 after training(Z＝-13.012,P＜0.001). The number of erroneous words was not correlated with age (r＝-0.045,P=0.626). Conclusions The articulation disorder of lingua-palatal phoneme is mainly replacement and lateral misarticulation. And specific speech rehabilitation training is effective for FAD.

摘要： 目的 探讨功能性构音障碍(FAD)患者舌面音异常的语音特点及康复效果。方法 选择2016年2月—2017年2月收治的120例FAD患者,分析其舌面音异常的语音特点,并对其进行针对性康复训练,对舌面音构音异常和年龄的关系进行关联性分析。结果 /j/音构音错误主要置换成/x/和/d/、侧化、脱落;/q/音主要置换成/j/、/x/、/t/和侧化;/x/音主要置换成/j/和侧化;三者均涉及的错误方式主要为置换(与u、i为介母的韵母组合时)和侧化(与i为介母的韵母组合时)。经过3~6周的针对性训练,104例痊愈,13例好转,总治愈率为86.67%(104/120),轻、中、重三组治愈率分别为100%(7/7)、82.61%(19/23)、86.67%(78/90)。发音错误字数由训练前的23.11±9.41减少到1.85±6.17,差异具有统计学意义(Z=-13.012,P<0.001)。FAD患者舌面音错误字数与年龄无明显相关性(r＝-0.045,P=0.626)。结论 舌面音构音错误类型主要为置换、侧化;针对性的康复训练是矫治FAD患者舌面音异常的有效措施。
