Project Summary/Abstract Vocal fatigue is a communication disorder that disproportionately affects occupational voice users such as teachers, call center workers, and religious officials.1–3 Classically, fatigue is composed of two dimensions: perceived fatigue and decrements in task performance.4–6 Researchers in exercise science use a variety of task protocols to elicit perceived fatigue and task performance decrements in the muscle. Only one task protocol, however—loud oral reading—is prevalent in voice research.7 Loud oral reading tasks take 1-2 hours to administer7 and expose vocally vulnerable participants to large vocal fold vibratory doses8–10 that may place them at risk of injury. In the ideal, vocal demand tasks (1) take fewer than 30 minutes to administer, (2) minimize vocal fold vibratory dose, and (3) maximize the contractile demands placed on the intrinsic laryngeal skeletal muscles most susceptible to fatigue. The goal of the proposed study is to validate a vocal demand task (the Fluid Interval Test for Voice, or FIT-V) that cleaves as closely as possible to these ideals, with the goal of sparking future vocal fatigue research and detecting, diagnosing, and treating vocal fatigue prior to the point of disability. Three specific aims support this goal: (SA1) to compare changes in perceived vocal exertion between the FIT-V task protocol and two control task protocols, (SA2) to compare vocal fold distance dose between the three tasks, assessing whether the FIT-V is non-inferior to the current standard in occupational vibratory risk,10,11 and (SA3) to screen several potential indices of task performance decrement, including pressure, flow, and biomechanical measures. The proposed training plan overseen by the University of Delaware uses multiple modalities to enhance the applicant’s ability to investigate vocal fatigue and become an independent, productive research scientist. First, mentored in-person and virtual training in disciplines such as perceived exertion, bioenergetics, and neuromuscular physiology will continue to develop the applicant’s proficiency in fatigue theory and integrated physiological systems. Second, coursework in clinical exercise physiology instrumentation and paradigms of performance testing will augment the applicant’s interdisciplinary rigor and ability to import new techniques, methods, and perspectives to voice science. Third, mentored in-person training and coursework will support the applicant’s ability to use advanced statistical techniques to analyze time-series data and accurately describe intrasubject change in fatigability over time. Fourth, data management training will improve the applicant’s ability to disseminate research findings and protect participant confidentiality. Fifth and finally, mentored training and distance coursework will teach the applicant to create simulation models of physiological systems and fatigue. These training aims will give the applicant multiple avenues through which to build upon existing experimental fatigue paradigms and innovate new approaches to the study of this disabling communication disorder.

项目摘要/摘要 发声疲劳是一种交流障碍，对职业性发声用户的影响不成比例，例如 作为教师、呼叫中心工作人员和宗教官员。1-3传统上，疲劳由两个维度组成： 运动科学领域的4-6名研究人员使用各种任务 导致肌肉疲劳和任务表现减退的方案。只有一个任务协议， 然而，大声朗读在语音研究中很普遍。7大声朗读任务需要1-2个小时 给容易发声的参与者使用声带振动剂8-10，这可能会使他们 冒着受伤的危险。在理想情况下，发声需求任务(1)只需不到30分钟的时间即可完成，(2)尽量减少发声 折叠振动剂量，(3)最大限度地增加对喉内骨骼肌的收缩需求 最容易疲劳。拟议研究的目标是验证发声需求任务(液体间隔 测试声音，或FIT-V)尽可能接近这些理想，目标是激发未来的声音 研究和检测，诊断和治疗发声疲劳之前的伤残。三个具体的 AIMS支持这一目标：(SA1)比较FIT-V任务方案和FIT-V任务方案在感知发声用力方面的变化 和两个控制任务协议，(SA2)比较三个任务之间的声带距离剂量，评估 FIT-V在职业振动风险方面是否不逊于现行标准，10，11和(SA3)筛查 任务绩效下降的几个潜在指标，包括压力、流量和生物力学测量。 由特拉华大学监督的拟议培训计划使用多种模式来增强 申请人研究发声疲劳的能力，并成为一名独立的、多产的研究科学家。 首先，在感知体力、生物能量学和 神经肌肉生理学将继续培养申请者对疲劳理论的熟练程度和综合能力 生理系统。第二，临床运动生理学仪器和范例的课程作业 性能测试将增强申请者跨学科的严谨性和引入新技术的能力， 发声科学的方法和前景。第三，有指导的面对面培训和课程作业将支持 申请人能够使用先进的统计技术分析时间序列数据并准确描述 受试者体内的疲劳性随时间的变化。第四，数据管理培训将提高申请者的能力 传播研究成果并保护参与者的机密性。第五也是最后一点，有指导的培训和 远程课程将教申请者创建生理系统和疲劳的模拟模型。 这些培训目标将为申请者提供多种途径，通过这些途径在现有实验的基础上进行改进 疲劳范式和创新的方法来研究这种致残的沟通障碍。
