A Review of Vocal Loading Tasks in the Voice Literature

SummaryVocal loading tasks (VLTs) are used to assess range of function and vulnerability of the laryngeal system. The manner in which VLTs compromise the laryngeal mechanism is multifaceted and only partially understood. This paper presents a scoping review of the literature on VLTs and their effects on the healthy voice. This review paper details the varied nature of VLT duration, task type, and additional factors including hydration and ambient noise that have been used to compromise the larynx. In addition, the voice measures used to assess the effects of VLTs on the healthy larynx are discussed. This study details the current state of the literature, draws conclusions from our current knowledge, and provides directions for further research.
