听觉言语障碍儿童言语时呼吸特征研究

目的研究听觉言语障碍儿童与正常儿童在言语状态下呼吸特性的差异,为探索听觉言语障碍儿童言语时呼吸训练方法提供参考。方法使用RM6240生理信号采集处理系统和Hx 100型呼吸换能器分别测量10例6～8周岁听觉言语障碍儿童和10例6～8周岁正常儿童在言语状态下的吸气最大值、呼气最大值及呼吸频率,比较两组结果。结果在言语状态下,听觉言语障碍儿童与正常儿童的腹式吸气最大值分别为29.03±1.51和39.67±1.34cmH2O,腹式呼气最大值分别为50.95±2.36和45.35±1.87cmH2O,胸式吸气最大值分别为21.46±0.87和27.97±0.63cmH2O,胸式呼气最大值分别为43.70±1.07和34.77±1.25cmH2O,听觉言语障碍儿童胸腹式呼吸状态的吸气最大值均低于正常儿童组,而呼气最大值均高于正常儿童组,且差异均有统计学意义(P<0.05);听觉言语障碍儿童在言语状态下呼吸频率值均高于正常儿童,且差异有显著统计学意义(P<0.01)。结论听觉言语障碍儿童言语状态下的言语动力源不能提供足够的呼吸支持,不能为正确发音提供强有力的气息,从而导致其呼吸器官、发音器官及构音器官不能很好的进行协调;在其听觉言语康复训练时应注重呼吸训练。

The Breathing Characteristics of Children with Hearing Speech Disorder When Speaking

Objective To study the breathing characteristics of 6~8 year old children with hearing speech disorder and normal children when speaking to provide evidence for speech training. Methods The RM 6240 physiological signal collection and processing system and Hx 100 respiratory transducer were used to collect the inspiration maximum,exhalation maximum and respiratory rate of ten 6~8 year old children with hearing speech disorder and ten normal children when speaking respectively. Results When speaking,the abdominal inspiration maximum for deaf children and normal children were 29.03±1.51 cmH2O and 39.67±1.34 cmH2O(P<0.01),the abdominal exhalation maximum for deaf children and normal children were 50.95±2.36 cmH2O and 45.35±1.87 cmH2O(P<0.05);the thoracic inspiration maximum for deaf children and normal children were 21.46±0.87 cmH2O and 27.97±0.63 cmH2O(P<0.05),the thoracic exhalation maximum for deaf children and normal children were 43.70±1.07 cmH2O and 34.77±1.25 cmH2O(P<0.01).The respiratory rate of children with hearing speech disorder was significantly higher than that of normal children(P<0.01). Conclusion Children with speech and hearing disorder showed poor coordination between respiration and speech because of a lack of respiration support.
