快速用力呼气法对发育迟缓儿童言语呼吸支持不足矫治的个案研究

A case study： The effectiveness of fast and forceful breathing training in the treatment of developmentally delayed children with insufficient respiratory support for speech

目的探索快速用力呼气法对治疗发育迟缓儿童言语呼吸支持不足问题的有效性。方法采用单一被试单基线A-B实验设计，运用快速用力呼气法对1名存在言语呼吸支持不足问题的发育迟缓儿童进行康复训练，测量、分析训练前后的最长声时和平均言语强度。结果训练后，该儿童最长声时和平均言语强度显著提高。结论快速用力呼气法对解决发育迟缓儿童呼吸支持不足的问题是有效的。

Objective TO explore the effectiveness of fast and forceful breathing train su in PP th ng in the treatment of developmentally delayed children with insufficient respiratory ort for speech. Methods A single-case baseline A-B experimental design was used s study. A child with insufficient respiratory support for speech received the fast and forceful breathing training. After the training, the maximum phonation time （MPT） and average speech intensity were measured before and after the training. Results After the training, the MPT and average speech intensity were improved significantly. Conclusion Fast and forceful breathing training is effective in solving the problem of insufficient respiratory support for speech in developmentally delayed children.
