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.

项目摘要/摘要声带疲劳是一种传播障碍，对职业语音用户的影响不成比例作为老师，呼叫中心的工人和宗教官员。1-3经典，疲劳由两个维度组成： 4-6运动科学研究人员使用各种任务引起感知疲劳和任务绩效降低肌肉的方案。只有一个任务协议，但是 - 口头阅读 - 语音研究很普遍。7大声的口头阅读任务需要1-2个小时才能 Administer7并将声音脆弱的参与者暴露于大声折振动剂量8-10，可能会将其放置有受伤的风险。在理想的情况下，声音需求任务（1）需要不到30分钟才能管理，（2）最小化人声折叠剂量，（3）最大化固有喉部骨骼肌肉的收缩需求最容易受到疲劳的影响。拟议的研究的目的是验证声音需求任务（流体间隔测试声音或fit-v）与这些想法尽可能接近的裂缝，目的是激发未来的声音在残疾点之前，疲劳研究和检测，诊断和治疗声带疲劳。三个具体目标支持此目标：（SA1）比较FIT-V任务协议之间感知到的声音努力的变化和两个控制任务协议，（SA2）比较三个任务之间的人声折叠距离剂量，评估 FIT-V是否不属于当前职业振动风险的标准，10,11和（SA3）任务绩效降低的几个潜在指标，包括压力，流量和生物力学测量值。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带疲劳并成为独立的产品研究科学家的能力。首先，在学科中进行了面对面和虚拟培训，例如感知的劳累，生物能学和神经肌肉生理学将继续发展申请人在疲劳理论方面的熟练程度并综合生理系统。第二，临床运动生理学仪器的课程和范例绩效测试将增加申请人的跨学科严格性和进口新技术的能力，方法和语音科学的观点。第三，受过指导的面对面培训和课程将支持申请人使用高级统计技术来分析时间序列数据并准确描述的能力随着时间的推移，疲劳性会变化。第四，数据管理培训将提高申请人的能力传播研究结果并保护参与者的机密性。第五，最后是指导培训，远程课程将教授应用程序以创建物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，以基于现有的实验疲劳范式和创新的新方法研究了这种禁用通信障碍。
