Anteroposterior diameters of the rib cage and abdomen were measured in profoundly hearing-impaired individuals in a standing position during respiratory maneuvers and utterance tasks. Data were charted in relative motion diagrams (rib cage vs abdomen) which enabled graphic solution for lung volume change, relative volume displacements of the rib cage and abdomen, and chest wall configuration. Function during resting tidal breathing was within normal limits. Function during utterance was frequently deviant in one or more of the following regards: (1) linguistic programming, (2) mechanical adjustments of respiratory origin, and (3) mechanical adjustments of the larynx and upper airway. Deviancies in mechanical adjustments of respiratory origin were confined mainly to lung volume events. Overall function is discussed with respect to the potential muscular mechanisms governing different respiratory behaviors. We conclude that both a lack of normal auditory sensation and inappropriate early speech skill instruction are responsible for the respiratory behaviors observed. Implications for clinical endeavors are detailed and data are presented to illustrate the power of biofeedback in managing speech disorders in the profoundly hearing impaired, when those disorders are partially respiratory based.
在呼吸动作和发声任务期间,对深度听力受损个体站立位时的胸廓和腹部前后径进行了测量。数据记录在相对运动图(胸廓与腹部)中,这使得能够通过图形求解肺容积变化、胸廓和腹部的相对容积位移以及胸壁形态。静息潮式呼吸期间的功能在正常范围内。发声期间的功能在以下一个或多个方面经常出现异常:(1)语言编程,(2)呼吸起源的机械调节,以及(3)喉和上气道的机械调节。呼吸起源的机械调节异常主要局限于肺容积事件。就控制不同呼吸行为的潜在肌肉机制讨论了整体功能。我们得出结论,缺乏正常的听觉感觉和不适当的早期言语技能指导是观察到的呼吸行为的原因。详细阐述了对临床工作的影响,并提供了数据以说明生物反馈在管理深度听力受损者的言语障碍方面的作用,当这些障碍部分基于呼吸时。
