The respiratory abilities of a group of 19 speech-disordered subjects with idiopathic Parkinson's disease were assessed using both spirometric and kinematic techniques and compared to those of a group of 19 nonneurologically impaired controls matched for age and sex. Results of the spirometric assessment showed that only a minority of the Parkinson's subjects had lung volumes and capacities outside normal limits. Consequently in the majority of cases, the speech disorder could not be related to any abnormality in lung function determined spirometrically. Chest wall dynamics during both conversation and reading were essentially normal in all cases. Approximately half of the Parkinson's subjects, however, exhibited irregularities in their chest wall movements while performing vowel prolongation and syllable repetition tasks. The same irregularities were not present in the chest wall movements exhibited by the control subjects, suggesting that their presence was in some way related to the Parkinson's disease. Results are discussed in terms of the effects of Parkinson's disease on neuromuscular function.
使用肺量计和运动学技术评估了一组19名患有特发性帕金森病的言语障碍受试者的呼吸能力，并将其与一组年龄和性别匹配的19名无神经功能损害的对照组受试者的呼吸能力进行了比较。肺量计评估结果显示，只有少数帕金森病受试者的肺容积和容量超出正常范围。因此，在大多数情况下，言语障碍与通过肺量计测定的肺功能异常无关。在所有病例中，谈话和阅读时的胸壁动力学基本正常。然而，大约一半的帕金森病受试者在进行元音延长和音节重复任务时，胸壁运动出现不规则。对照组受试者的胸壁运动中不存在同样的不规则情况，这表明这些不规则情况在某种程度上与帕金森病有关。根据帕金森病对神经肌肉功能的影响对结果进行了讨论。
