The respiratory abilities of a group of 20 subjects with a speech disorder resulting from severe closed head injury (CHI) were assessed using both spirometric and kinematic techniques and compared with those of a group of 20 non-neurologically impaired controls matched for age and gender. Results of the spirometric assessment showed that the CHI subjects as a group had lower vital capacities and lower forced expiratory volumes 1 second than the controls. Kinematic assessment also showed that the CHI subjects had problems co-ordinating the action of the rib-cage and abdomen when carrying out speech tasks such as vowel prolongations, syllable repetitions and reading. Results are discussed in terms of the effects of CHI on neuromuscular function.
采用肺活量测定和运动学技术，对一组20名因严重闭合性颅脑损伤（CHI）导致言语障碍的受试者的呼吸能力进行了评估，并与一组年龄和性别匹配的20名无神经功能障碍的对照组受试者的呼吸能力进行了比较。肺活量测定评估结果显示，与对照组相比，CHI受试者作为一个整体，其肺活量和1秒用力呼气量较低。运动学评估还显示，CHI受试者在进行诸如元音延长、音节重复和阅读等言语任务时，在协调胸廓和腹部的动作方面存在问题。根据CHI对神经肌肉功能的影响对结果进行了讨论。
