最长声时测量在聋儿言语呼吸中的指导意义

The significance of maximum phonation time measurement in speaking respiration

目的 验证聋儿在口语发展过程中获得呼吸支持的重要性,建立学前和学龄低、中、高年级儿童的最长声时(MPT)常模;体现最长声时在聋儿言语呼吸中的指导价值;证明腹式呼吸较胸式呼吸能够提供更多的言语呼吸支持。方法 在上海市随机选取4-17岁640名健听儿童,从国内外数家省康复中心随机选出共29名配戴助听器且采用腹式呼吸的重度聋儿,以及25名接受胸式呼吸训练的重度佩戴助听器聋儿。方法:根据每个实验目的进行最长声时分组测试,测试设备采用“实时言语矫治仪”。结果(1)最长声时在不同年龄组及性别方面均存在显著差异;(2)耳聋组接受康复前,最长声时显著低于健听组,经过一年康复之后,最长声时重复测量显著高于健听组;(3)耳聋组胸式呼吸的最长声时明显短于腹式呼吸。结论 最长声时作为衡量言语呼吸质量的最佳指标之一,可以在聋儿康复中得到广泛应用,以指导聋儿在言语过程中建立自然的腹式呼吸方式。

Purpose;To testify the importance of acquiring the respiration support during the oral language development for thedeaf children, (1) Established the norms of the maximum phonation time (MPT) of Chinese children; (2) Embodied the guiding value ofMPT in the speech and language training for the deaf children; (3) The abdomen breathing is suitable for the speech and languagedevelopment of the deaf children. Subjects: In Shanghai, selected 840 normal children aged 4-17, 29 deaf children with hearing aids whoadapted the thorax breathing in several provisional rehabilitation center, and 25 deaf children who adapted the abdomen breathingthrough one year of breath training from several countries were randomly selected. Methods: Respectively taking the three subsidiaryexperiments, in which the MPTs of each group were tested according to the purpose of every experiment by“Real time Analysis'.Results: (1) MPTs had significant difference in both age groups and gender groups. (2) Before training, MPTs of deaf children wereshorter than the normal children, and after one year of training, the deaf children had the longer MPT than the normal children. (3)MPTs of thorax breathing were much shorter than the abdomen breathing. Conclusion: As the optimum parameter of measuring thequality of speech breathing, MPT can be used broadly in the speech training for the deaf children, and helps to establish the naturalabdomen breathing style in the process of speech.'
