The possibility that prephonatory chest wall posturing is abnormal in stutterers was explored by observing rib cage and abdominal hemicircumference changes during the interval between the presentation of a stimulus and the production of/alpha/by a group of stutterers (N = 5). It was found that the patterns of chest wall adjustment for phonation were qualitatively identical in the stutterers and in a comparable group of normal men studied previously. There was, however, a significant difference in the way in which lung volume changed during the execution of the chest wall adjustment. This was considered to be indicative of delayed glottal closure among the stutterers rather than representative of a primary ventilatory disturbance.
通过观察一组口吃者（N = 5）在刺激呈现与发出/α/音之间的间隔期内胸廓和腹部半周长的变化，探讨了发声前胸壁姿势异常在口吃者中的可能性。研究发现，口吃者和先前研究的一组正常男性在发声时胸壁调整模式在质量上是相同的。然而，在胸壁调整过程中肺容积变化的方式存在显著差异。这被认为表明口吃者声门闭合延迟，而非代表原发性通气障碍。
