摘要

目的：喉内收肌张力障碍（AdLD）、声带震颤和声带麻痹/瘫痪等神经源性嗓音疾病会影响发音系统的神经肌肉控制，从而可能导致发音起始/偏移受损。本研究利用喉高速视频内窥镜（HSV），研究了几种神经源性嗓音疾病患者在持续发声时，软声门、习惯性声门和硬声门攻击模式下的声门攻击时间（GAT）和声门偏移时间（GOT）。方法：研究人员同时获得了 14 名神经源性嗓音疾病患者和 14 名正常嗓音患者在软声门、习惯性声门和硬声门攻击模式下两次发出 /i/ 发音时的 HSV 数据和音频记录。使用 HSV 测量了 GAT（定义为发声时声带第一次摆动与声带第一次接触之间的时间间隔）和 GOT（定义为发声偏移时声带最后一次摆动与声带最后一次接触之间的时间间隔）。在各组内比较了不同声门攻击模式下的 GAT 和 GOT，还在不同障碍和正常嗓音参与者之间进行了比较。此外，还比较了正常嗓音参与者和 AdLD 患者在持续发音和连接语音时的这些数值：结果：神经源性障碍组在硬喉音攻击模式下的 GAT 值明显高于正常嗓音参与者。声带震颤的习惯性 GOT 值与单侧声带麻痹和 AdLD 的习惯性 GOT 值明显不同。此外，正常嗓音受试者在不同声门攻击模式下的连贯言语和持续发音的 GAT 有相似的趋势，而 AdLD 组则没有。AdLD 参与者的 GOT 也有相同的趋势，而正常嗓音参与者则没有：本研究提供了不同神经源性嗓音疾病在持续发音时 GAT 和 GOT 值差异的证据，有助于了解这些疾病的病理生理学。这些发现可为神经源性嗓音疾病临床评估策略和语音任务的开发提供参考。

Study of Glottal Attack Time and Glottal Offset Time in Neurogenic Voice Disorders During Sustained Phonation.

Objective: Neurogenic voice disorders like adductor laryngeal dystonia (AdLD), vocal tremor, and vocal paresis/paralysis impact the neuromuscular control of the phonatory system, which might lead to an impaired phonation onset/offset. Utilizing laryngeal high-speed videoendoscopy (HSV), this study investigates the glottal attack time (GAT) and glottal offset time (GOT) during soft, habitual, and hard glottal attack modalities in sustained phonation for several neurogenic voice disorders.

Methods: HSV data and audio recordings were obtained simultaneously from 14 participants with neurogenic voice disorders and 14 normophonic participants during two productions of the /i/ vowel at soft, habitual, and hard glottal attacks. Using HSV, GAT, defined as the time interval between the first oscillation and the first contact of the vocal folds at phonation onset, and GOT, the time interval between the last oscillation and the last contact of the vocal folds at phonation offset, were measured. GAT and GOT for different glottal attack modalities were compared within each group, also among the different disorders and normophonic participants. Additionally, these values were compared between sustained phonation and connected speech for the normophonic participants and those with AdLD.

Results: The neurogenic disorders group exhibited significantly higher GAT values than the normophonic participants during the hard glottal attack modality. Habitual GOTs for vocal tremor were significantly different than those of unilateral vocal fold paralysis and AdLD. Moreover, the normophonic participants shared similar trends between connected speech and sustained phonation across glottal attack modalities for GAT, while the AdLD group did not. AdLD participants shared the same trend for GOT, while normophonic participants did not.

Conclusions: This study provides evidence of differences in GAT and GOT values during sustained phonation across different neurogenic voice disorders, contributing to the understanding of their pathophysiology. These findings may inform the development of strategies and speech tasks for clinical assessment of neurogenic voice disorders.
