OBJECTIVE ASSESSMENT OF VOCAL HYPERFUNCTION

最常见的发音障碍类型是 与发声滥用及/或误用有关，即“发声机能亢进”。 然而，缺乏具体的确凿数据：L)具体 声带功能亢进的生理和声学表现 功能亢进在语音发育和维持中的实际作用 精神错乱。因此，该项目的主要目标是进一步开发和 使用发声的定量测量来提供客观 对称为发声功能亢进的情况的描述。这部作品 将涉及使用非侵入性的、间接的声门空气测量 流量、跨声门气压、相对声带接触面积(EGG)、 呼吸功能，颈表面肌电(EMG)和一些 研究有机(结节、息肉、接触性溃疡)的衍生措施 和非器质性(功能性发音障碍/失声)声带表现 机能亢进。这些测量将与编码的 喉部病理生理状态的描述(摘自 视频喉镜检查/频闪镜检查)，相关的医疗和心理社会因素 以及声音的知觉特征。对结果的解释 将通过使用一个简单的声带振动模型来辅助。 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 与过度功能有关的嗓音障碍。数据分析和 口译将继续与这一框架相关。建议数 工作将在以前努力的基础上，重点放在一些具体的 与功能亢进和正常发声相关的研究 L)对不同类型功能亢进症的分组研究 嗓音障碍；2)继续一项研究，检查 女性声带小结的行为治疗：3)知觉 病理性发声功能的评估(特别是与变化相关的 通过治疗改善发声功能)；以及4)探索潜在的 通过使用声带建模的机制。关于正常嗓音的研究 生产将侧重于扩大我们的标准数据库，包括 男性和老年群体的代表性增加。我们将延长 多变量水平的数据分析，希望能有更多的发展 有效的发声功能统计模型。更多的研究将 重点是直接考察新事物之间的具体关系 从选定的正常和病理中获得的测量的组合 研究对象。从这些努力中获得的信息应该会导致新的 关于发声功能亢进病因的见解，以及 诊断和治疗这些疾病的临床方法的改进 精神错乱。

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: l) 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, neck surface electromyography (EMG) 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 aided 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 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: l) a group-based study of different types of hyperfunctional voice disorders; 2) continuation of a study examining the efficacy of behaviorally-based treatment of vocal nodules in women; 3) perceptual evaluation of pathological vocal function (particularly related to changes in vocal function with treatment); and 4) exploration of underlying mechanisms through the use of vocal fold modeling. Studies of normal voice production will focus on enlargement of our normative data base with increased representation of males and older age groups. We will extend data analysis to the multivariate level in the hopes of developing more effective statistical models of vocal function. Additional studies will focus on the direct examination of specific relationships between new combinations of measures obtained from selected normal and pathological subjects. 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.
