To describe the origins of the task elicitation procedure for determining phonation threshold pressure and, through a literature review and online survey, describe published procedural, environmental, and participant variable departures from the original methodology.
Literature search terms included phonation threshold pressure, subglottal pressure and phonation, pressure measurement and phonation, lung pressure and phonation, and vocal fold oscillation onset. Inclusion criteria were limited to indirect assessment of phonation threshold pressure, English language publications between 1980 and 2009, and peer-reviewed journals. Studies including animals, computer or physical models, alaryngeal speakers, laryngeal airway resistance, or any airflow interruption technique were excluded. Twenty-four articles matched the inclusionary criteria. An online survey to query task elicitation procedures was then developed from the literature review.
The scientific rationale for inclusion of phonation threshold pressure data was consistent across published studies; however, variations in procedural methodology for task elicitation were identified, as were environmental and participant inconsistencies that might affect phonation threshold pressure values. Findings of the online survey mirrored the inconsistencies identified in the literature review.
The methodological differences for task elicitation identified in this comprehensive review of the literature and the online survey, while bringing into question the reliability of phonation threshold pressure measurement, illuminate scientific questions yet to be answered to further refine and potentially standardize phonation threshold pressure as a more reliable research and clinical measurement.
描述确定发声阈压的任务诱发程序的起源，并通过文献回顾和在线调查，描述从原始方法学中偏离的已发表的程序、环境和参与者变量。
文献检索词包括发声阈压、声门下压和声门、压力测量和声门、肺压和声门和声带振动起始。纳入标准仅限于发声阈压的间接评估、1980 年至 2009 年期间的英文出版物以及同行评审期刊。排除包括动物、计算机或物理模型、喉切除者、喉气道阻力或任何气流中断技术的研究。有 24 篇文章符合纳入标准。然后，根据文献综述开发了一项在线调查，以查询任务诱发程序。
纳入发声阈压数据的科学依据在已发表的研究中是一致的；然而，任务诱发的程序方法存在差异，环境和参与者的不一致性也可能影响发声阈压值。在线调查的结果反映了文献综述中发现的不一致性。
本研究对文献的全面回顾和在线调查中发现的任务诱发方法学差异，虽然对发声阈压测量的可靠性提出了质疑，但阐明了尚未回答的科学问题，以进一步完善和可能标准化发声阈压作为更可靠的研究和临床测量。
