To examine the effects of cognitive-linguistic deficits and respiratory physiologic changes on respiratory support for speech in individuals with Parkinson's disease (PD) using two speech tasks: reading and extemporaneous speech.
Five women with PD, 9 men with PD, and 14 age- and sex-matched control participants read a passage and spoke extemporaneously on a topic of their choice at comfortable loudness. Sound pressure level, syllables per breath group, speech rate, and lung volume parameters were measured. Number of formulation errors, disfluencies, and filled pauses were counted.
Individuals with PD produced shorter utterances compared with control participants. The relationships between utterance length and lung volume initiation and inspiratory duration were weaker for individuals with PD than for control participants, particularly for the extemporaneous speech task. These results suggest less consistent planning for utterance length by individuals with PD in extemporaneous speech. Individuals with PD produced more formulation errors in both tasks and significantly fewer filled pauses in extemporaneous speech.
Both respiratory physiologic and cognitive-linguistic issues affected speech production by individuals with PD. Overall, individuals with PD had difficulty planning or coordinating language formulation and respiratory support, particularly during extemporaneous speech.
使用两种言语任务（朗读和即兴演讲）来研究认知语言缺陷和呼吸生理变化对帕金森病（PD）患者言语呼吸支持的影响。
5 名女性 PD 患者、9 名男性 PD 患者和 14 名年龄和性别匹配的对照参与者在舒适的音量下朗读一篇文章并就其选择的主题即兴演讲。测量声压级、呼吸群音节数、言语率和肺容积参数。计算构词错误、不流畅和填充停顿的次数。
PD 患者的话语比对照参与者短。与对照参与者相比，PD 患者的话语长度与肺容积起始和吸气持续时间之间的关系较弱，尤其是在即兴演讲任务中。这些结果表明 PD 患者在即兴演讲中对话语长度的规划不太一致。PD 患者在两种任务中都产生了更多的构词错误，并且在即兴演讲中明显减少了填充停顿。
呼吸生理和认知语言问题都影响了 PD 患者的言语产生。总体而言，PD 患者在规划或协调语言构词和呼吸支持方面存在困难，尤其是在即兴演讲中。
