舌边音构音障碍的临床特点及康复训练

Clinical Characteristics and Rehabilitation Training of Lateral Consonant Articulation Disorders

目的探讨功能性构音障碍(FAD)患者舌边音/l/构音障碍的临床特点和康复训练方法。方法分析107例FAD患者舌边音构音障碍特点;对其中30例舌边音构音障碍患者进行康复训练;对舌边音构音障碍和年龄的关系进行关联性分析和简单线性回归分析。结果 /l/的构音错误形式主要是置换成/n/、/y/、/r/、/d/或脱落;当/l/与含有前元音/i/、/ü/的韵母相拼时,构音错误以脱落为主;当/l/与含有/a/、/o/、/e/、/u/的韵母相拼时,置换稍多于脱落。语音训练后,患者舌边音构音错误数显著减少(P<0.001)。FAD患者舌边音错误数与年龄呈负相关(r=-0.840),年龄对舌边音构音错误的决定系数为0.422。结论舌边音构音错误形式主要为置换或脱落,舌边音与不同韵母相拼时出现的错误不同;有针对性的康复训练疗效确切;年龄是影响舌边音构音障碍预后的重要因素。

Objective To explore the clinical characteristics and rehabilitation training of abnormal lateral consonant, namely/l/, of pa-tients with functional articulation disorders （FAD）. Methods 107 patients with FAD were observed of the clinical characteristics of/l/. 30 pa-tients with/l/articulation disorder accepted speech training. The correlation and simple linear regression analysis were carried out on/l/ar-ticulation disorders and age. Results The articulation disorder of/l/ mainly showed replacement for/n/,/y/,/r/,/d/ or omission. When/l/combined with vowels contained/i/and/u/, the main error was omission. When/l/combined with vowels contained/a/,/o/,/e/or/u/, the er-rors trended to be replacement rather than omission. After speech training, the patients made less mistakes about/l/（P〈0.001）. The frequen-cy of/l/articulation disorders was negatively correlated with age （r=-0.840）. The result of simple linear regression analysis showed that the determination coefficient was 0.422. Conclusion The/l/articulation disorder mainly shows replacement or omission, varied with the vow-els. The targeted rehabilitation training may be helpful. Age plays an important role in the outcome of/l/articulation disorder.
