OBJECTIVE ASSESSMENT OF VOCAL HYPERFUNCTION

最常见的发音障碍类型是那些 与发声滥用和/或误用有关，即“发声功能亢进”。 然而，缺乏关于以下方面的硬数据：1)具体 声带功能亢进的生理和声学表现(2) 功能亢进在心力衰竭的发展和维持中的实际作用 嗓音障碍。因此，该项目的主要目标是进一步 开发和使用发声的量化措施，以提供 客观描述称为发声功能亢进的情况。 这项工作将涉及使用非侵入性的、间接的措施 声门空气流量、跨声门气压、相对声带接触 面积(EGG)、呼吸功能和一些衍生措施 研究有机(结节、息肉、接触性溃疡)和非有机 (功能性发音障碍/失声)发声功能亢进的表现。 这些措施将结合以下编码描述进行检查 喉部的病理生理状态(摘自 视频喉镜/频闪镜)，相关的医疗和心理社会 声音的因素和知觉特征。解读 结果将通过使用一个简单的声带模型来添加 震动。 该项目的总体设计继续基于一套 构成声乐描述性框架的相互关联的假设 机能亢进。该框架认为，有不同的类型和 与过度功能相关的发声障碍的分期。数据分析和 口译将继续与这一框架相关。这个 拟议的工作将在以前努力的基础上，侧重于以下几个方面 与功能亢进和正常嗓音相关的具体研究 制作包括：对不同类型的 功能亢进性嗓音障碍，“声带压力测试”，疗效 以行为为基础的发声疗法，以及对正常发声和发声的研究 受试者内部的变异与发声功能的测量有关。这个 从这些努力中获得的信息应该会带来新的见解 关于发声功能亢进的病因，以及对 用于诊断和治疗这些疾病的临床方法。

The most frequently occurring types of voice disorders are those that are related to vocal abuse and/or misuse, i.e., "vocal hyperfunction". However, there is a paucity of hard data concerning: 1) specific physiologic and acoustic manifestations of vocal hyperfunction, and 2) the actual role of hyperfunction in the development and maintenance of voice disorders. Thus, the major goal of this project is to further develop and use quantitative measures of voice production to provide objective descriptions of conditions referred to as vocal hyperfunction. This work will involve the use of non-invasive, indirect measures of glottal air flow, transglottal air pressure, relative vocal fold contact area (EGG), respiratory function, and a number of derived measures to study both organic (nodules, polyps, contact ulcers) and non-organic (functional dysphonia/aphonia) manifestations of vocal hyperfunction. These measures will be examined in relation to encoded descriptions of the pathophysiologic status of the larynx (from videolaryngoscopy/stroboscopy), pertinent medical and psychosocial factors and perceptual characteristics of the voice. Interpretation of results will be added through use of a simple model of vocal-fold vibration. The overall design of this project continues to be based on a set of interrelated hypotheses which form a descriptive framework for vocal hyperfunction. The framework holds that there are different types and stages of hyperfunctionally-related voice disorders. Data analysis and interpretation will continue to be related to this framework. The proposed work will build on previous efforts by focusing on a number of specific investigations related to hyperfunctional and normal voice production including: group-based studies of different types of hyperfunctional voice disorders, "vocal stress testing", efficacy of behaviorally-based voice therapy, and studies of normal inter- and intra-subject variation associated with measures of vocal function. The information gained from these efforts should lead to new insights concerning the etiology of vocal hyperfunction, and to improvements in clinical methods used to diagnosis and treat these disorders.
