Velopharyngeal control in individuals with Parkinson's disease (PD) was studied by obtaining rates of nasal airflow during syllable repetitions. Nasal airflows were described with respect to disease progression, phonetic context, and speaking rate. Significant differences in nasal airflows were obtained for disease progression and phonetic context. The data suggested that velopharyngeal control deteriorates systematically with disease progression. Parkinson's patients at mild and moderate levels of disease progression differentiated the nasal consonant from the oral consonants with increased nasal airflow associated with the nasal consonant. Differences, while not significant, were also observed in nasal flow rate values when the PD patients increased speaking rate from 1 to 5 syllables per second.
通过获取音节重复过程中的鼻气流速率，对帕金森病（PD）患者的腭咽控制进行了研究。根据疾病进展、语音背景和说话速率对鼻气流进行了描述。在疾病进展和语音背景方面，鼻气流存在显著差异。数据表明，腭咽控制随着疾病进展而系统性恶化。处于轻度和中度疾病进展水平的帕金森病患者能够区分鼻音辅音和口腔辅音，与鼻音辅音相关的鼻气流增加。当帕金森病患者的说话速率从每秒1个音节增加到每秒5个音节时，鼻气流速率值也观察到了差异，尽管不显著。
