项目摘要

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.

项目概要/摘要声音疲劳是一种沟通障碍，对职业声音使用者造成不成比例的影响，例如例如教师、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：感知疲劳和任务表现下降。4-6 运动科学研究人员使用各种任务引起肌肉疲劳和任务表现下降的协议只有一个任务协议，然而，大声朗读在声音研究中很普遍。7 大声朗读任务需要 1-2 小时才能完成。管理7并使声音容易受到大声带振动剂量8-10的影响，这可能会使他们在理想的声音需求任务中，(1) 执行时间少于 30 分钟，(2) 尽量减少声音。折叠振动剂量，以及（3）最大化对内在喉骨骼肌的收缩需求拟议研究的目标是验证声音需求任务（流体间隔）。声音测试（FIT-V），尽可能接近这些理想，目标是激发未来的声音在残疾之前研究和检测、诊断和治疗声音疲劳。目标支持这一目标：（SA1）比较 FIT-V 任务协议之间感知发声的变化和两个控制任务协议（SA2）来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劣于现行标准10,11和(SA3)进行筛选任务绩效下降的几个潜在指标，包括压力、流量和生物力学指标。由特拉华大学监督的拟议培训计划采用多种方式来增强申请人调查声音疲劳并成为一名独立、富有成效的研究科学家的能力。首先，在感知努力、生物能量学和神经肌肉生理学将继续培养申请人对疲劳理论和综合能力的熟练程度第二，临床运动生理学仪器和范例的课程。性能测试将增强申请人的跨学科严谨性和引进新技术的能力，第三，指导性的面对面培训和课程将支持声音科学。申请人使用先进统计技术分析时间序列数据并准确描述的能力第四，数据管理培训将提高申请人的能力。第五，最后，指导培训和保护参与者的机密。远程课程将教申请人创建生理系统和疲劳的模拟模型。这些培训目标将为申请人提供多种途径，以利用现有的实验疲劳范式并创新研究这种致残性沟通障碍的新方法。
