Speech Development in Children with Cerebral Palsy

描述(申请人提供)：脑性瘫痪(CP)是一种非进行性的、以神经学为基础的运动障碍综合征，通常在出生后18个月内被诊断出来(Rosenbaum等人，2002年)。研究表明，高达88%的CP患者有构音障碍(阿喀琉斯，1955)。构音障碍的一个重要后果是言语清晰度降低(York kston et al.，1999)，这反过来又经常导致对社会参与和教育/职业追求的干扰。尽管有越来越多的文献研究脑性瘫痪儿童的粗大和精细运动发育(Hanna等人，2003；Rosenbaum等人，2002)，但还没有研究这一人群中言语的纵向发展。因此，通过自然语言进行交流的长期前景和结果是不确定的。对患有构音障碍的儿童的言语发展的研究提供了一个机会，通过确定影响构音障碍儿童可懂度的具体变量，并明确这些变量如何随时间变化以及这些变化对可懂度的相对影响，来推进语音可懂度的综合理论。凯瑟琳·赫斯塔德博士是威斯康星大学麦迪逊分校终身教职助理教授。她的目标是将她目前专注于成人CP的研究扩展到CP儿童的言语发展研究。这项拟议的前瞻性纵向研究将在四年内收集26名患有脑瘫的儿童的语音清晰度、频谱和时间声学测量以及言语的感知/分段特征的数据。韦斯曼中心和威斯康星大学麦迪逊分校非常适合实现职业发展计划的目标，该计划将重点放在以下方面：儿童运动发育和运动性言语障碍领域的高级内容知识；言语测量技术方面的技术专长，包括声学分析程序和构音障碍的分段特征；以及纵向研究设计和分析方面的技术专长，包括临床调查和测量方面的一般问题。该项目的主要导师雷·肯特教授在构音障碍和言语科学方面拥有丰富的研究经验和专业知识。他将在言语发展、儿童运动性言语障碍和声学分析程序等领域提供一对一的指导和指导。

DESCRIPTION (provided by applicant): Cerebral palsy (CP) is a non-progressive, neurologically-based, motor impairment syndrome that is usually diagnosed within the first 18 months of life (Rosenbaum et al., 2002). Research suggests that up to 88% of those with CP have dysarthria (Achilles, 1955). One important consequence of dysarthria is reduced speech intelligibility (Yorkston et al., 1999), which in turn frequently results in interference with social participation and educational / vocational pursuits. Although there is a growing body of literature examining gross and fine motor development in children with CP (Hanna et al., 2003; Rosenbaum et al., 2002), there have been no studies examining the longitudinal development of speech in this population. Thus, long-term prognoses and outcomes for communication via natural speech are uncertain. The study of speech development in children with CP presents an opportunity to advance a comprehensive theory of speech intelligibility by identifying specific variables that contribute to intelligibility in children with dysarthria; and specifying how these variables change over time along with the relative effects of these changes on intelligibility. Katherine Hustad, Ph.D., is a tenure-track assistant professor at the University of Wisconsin - Madison. Her goal is to extend her current research, focused on adults with CP, to the study of speech development in children with CP. The proposed prospective longitudinal study will gather data regarding speech intelligibility, spectral and temporal acoustic measures and perceptual / segmental features of the speech of a cohort of 26 children with CP beginning between the ages of 24 and 48 months over a four year period. The Waisman Center and the University of Wisconsin - Madison are ideally suited to meet the goals of the career development plan, which will focus on the Pl's acquisition of: advanced content knowledge in the domains of motor development and motor speech disorders in children; technical expertise in speech measurement techniques including acoustic analysis procedures and segmental characterization of dysarthric speech; and technical expertise in longitudinal research design and analysis, including general issues in clinical investigation and measurement. The primary mentor for this project, Professor Ray Kent, has extensive research experience and expertise in dysarthria and speech science. He will provide one-on-one instruction and mentorship in the areas of speech development, motor speech disorders in children, and acoustic analysis procedures.
