SPEECH BREATHING KINEMATICS ACROSS THE HUMAN LIFE SPAN

非侵入性的空气动力学方法将用于研究各种 正常言语呼吸和言语呼吸障碍的方面。 将进行四项初步调查。 第一 调查将记录正常出现的性质 并提供婴幼儿言语呼吸的数据 婴幼儿言语呼吸基地 疾病可以比较。 第二次调查将测试 元音产生过程中喉气道阻力假说 随着年龄的增长而减少，从而导致 呼吸器的补偿调节。 相同的 调查还将提供所需的规范数据， 成人嗓音障碍的临床评估和管理 所有年龄段的人。 第三次调查将阐明机制 参与语言呼吸障碍的个体， 帕金森氏症。 这项调查将扩大了解 神经运动障碍对语言产生的影响， 为评价提供有价值的信息 和帕金森症患者的管理。 第四 一项调查将测试异常束缚对语言的影响 腹部轻瘫或麻痹患者的呼吸 是由脊髓损伤引起的 本次调查的数据 将直接影响临床管理策略 语言呼吸控制的研究 影响腹部肌肉控制的损伤。 的应用 上述四项调查应扩大到各种 由神经运动功能障碍引起的疾病，包括脑 麻痹、脊髓损伤、脊髓灰质炎、重症肌无力、脊髓 肌肉萎缩、周围神经病变、肌营养不良和 他人

Non-invasive aeromechanical methods will be used to study various aspects of normal speech breathing and speech breathing disorders. Four primary investigations will be conducted. The first investigation will document the nature of the emergence of normal speech breathing in infants and young children and provide a data base against which infants and young children with speech breathing disorders can be compared. The second investigation will test the hypothesis that laryngeal airway resistance during vowel production decreases with age and thereby leads to the development of compensatory adjustments of the breathing apparatus. The same investigation also will provide normative data needed to enhance the clinical evaluation and management of voice disorders in adults of all ages. The third investigation will elucidate the mechanism involved in speech breathing disorders in individuals with Parkinson's disease. This investigation will expand understanding of the impact of neuromotor impairments on speech production and contribute information of value for application to the evaluation and management of persons with parkinsonism. The fourth investigation will test the effects of abnormal trussing on speech breathing in individuals with abdominal paresis or paralysis resulting from spinal cord injury. Data from this investigation will have a direct impact on strategies for the clinical management of speech breathing control in individuals with neuromotor impairments affecting abdominal muscle control. Applications of the four investigations mentioned should extend to various disorders caused by neuromotor dysfunction, including cerebral palsy, spinal cord injury, poliomyelitis, myasthenia gravis, spinal muscular atrophy, peripheral neuropathy, muscular dystrophy, and others.
