目的　研究儿童发音缺陷的类型与疗效的有关因素 ,不同类型发音缺陷的疗效比较 ,以及语音治疗的临床模式。方法　在排除了器质性发音障碍后 ,对 91例汉语辅音音素性发音缺陷按发音部位进行分类 ;发音缺陷儿童经治疗后按症状的消失与否分成治疗有效组和无效组 ;列出 10个分析因素 ,即性别、年龄、口腔运动功能问题、发育迟缓、语言发育迟缓史、中耳炎史、舌系带问题、智能迟缓、治疗频度和治疗次数。采用SPSS 8 0 (SPSSInc .,1997)统计软件进行Logistic多元逐步回归分析 ,以寻找与疗效有关的因素 ;比较了单一类型和广泛类型发音缺陷 (发音缺陷≥ 2类 )的疗效 ;探讨语音治疗的临床模式。结果　 91例辅音音素性发音缺陷主要分为 4类 ,最多见的是广泛发音缺陷 ,共 37例 ,占 4 1% ;其次是舌后音 ,共 33例 ,占 36 % ;然后舌尖中音 ,共 12例 ,占 13% ;再就是舌尖音 ,共 8例 ,9% ,仅 1例为唇齿音 /f/的缺陷。Logistic多元回归分析表明发育迟缓、语言迟缓和治疗频度与疗效有关。单一类型发音缺陷的治疗有效率高达 87% ,而广泛发音缺陷的治疗有效率仅 2 7% ,二者疗效差异有非常显著意义 (P <0 0 0 0 1)。结论　临床音素性发音缺陷有 4类 ,发育迟缓、语言发育迟缓和语音治疗频度影响疗效 ,应适当增加每周的治疗次 Objective To study the factors related to the type and effect of pronunciation defects in children, the curative effects of different types of pronunciation defects, and the clinical modalities of speech therapy. Methods After excluding organic dysphonia, 91 cases of Chinese consonant phonetic pronunciation defects were categorized according to pronunciation sites. After treatment, children with pronunciation defects were divided into treatment-effective group and invalid group according to the disappearance of symptoms or not. Ten Analysis of factors, namely, gender, age, oral motor function problems, stunting, history of language delay, history of otitis media, tongue laceration, mental retardation, frequency of treatment and frequency of treatment. Logistic multivariate stepwise regression analysis using SPSS 8 0 (SPSSInc., 1997) software was used to find the factors related to efficacy. The curative effects of single type and extensive type of pronunciation defects (type 2) were compared; Clinical model. Results 91 cases of consonant phonemes of pronunciation defects are mainly divided into four categories, the most common is the widespread pronunciation defects, a total of 37 cases, 41%; followed by the tongue after the tone, a total of 33 cases, accounting for 36%; then the tongue midline, A total of 12 cases, accounting for 13%; then there is the tongue apex, a total of 8 cases, 9%, only 1 case of lip teeth / f / defect. Logistic multivariate regression analysis showed that stunting, language delay and frequency of treatment were related to efficacy. The treatment efficiency of single type pronunciation defects was as high as 87%, while the treatment efficiency of extensive pronunciation defects was only 27%. There was significant difference between the two groups (P <0.01 01). Conclusions There are 4 types of defects in clinical phonemic pronunciation, which are related to delayed onset of speech, delay of speech development and frequency of phonetic treatment. Weekly treatment times should be appropriately increased
