Abstract

Purpose: The aim was to compare cervical vestibular evoked myogenic potential (cVEMP) findings between pilots who are susceptible to airsickness and those who are not and to determine whether the physiopathology arising from the sacculo-collic reflex pathway occurs during episodes of airsickness in pilots.

Method: The patient group included 32 male pilots susceptible to airsickness, and the control group included 30 male pilots with no airsickness susceptibility. Participants with hearing loss and neuromuscular pathology were excluded. The Graybiel scale and cVEMP test were administered to the participants. The cVEMP thresholds, wave latencies and amplitudes, and interaural amplitude asymmetry ratios (IAARs) were compared between the groups. In addition, correlation analysis was performed between IAAR and susceptibility to airsickness severity in the airsickness susceptible (AS) group.

Results: The right-ear cVEMP threshold in the AS group (85.62 ± 6.05) was lower than that of the control group (91.16 ± 4.85; p < .001). In the right ears of the AS group, the P1 and N1 latencies at 100, 95, and 90 dB nHL levels were found to be shorter than those of the control group (p < .05 for all). Again, the P1N1 wave amplitudes at 100 dB nHL in the right ears of the AS group were higher than those of the control group (p = .009). The IAAR was higher in the AS group than in the control group (p < .001). There was a positive correlation between IAAR and airsickness susceptibility severity in the AS group (ρ = .742, .650, .535 at 100, 95, 90 dB nHL, respectively).

Conclusions: The susceptibility of pilots to airsickness may be related to changes in normative cVEMP latencies and amplitudes. The present study demonstrated a correlation between asymmetry in the integrity of the saccular reflex pathway and the severity of pilots' susceptibility to airsickness. A higher IAAR was observed in subjects with a greater susceptibility to airsickness, indicating a potential correlation between the two variables.

利用颈椎前庭诱发肌源电位研究飞行员晕机易感性的发病机制。

目的：比较易晕机和非晕机飞行员的颈椎前庭诱发肌源性电位（cemp）结果，以确定晕机期间是否发生由糖-结肠反射通路引起的生理病理。方法：患者组为32名易晕机的男性飞行员，对照组为30名无晕机易感性的男性飞行员。排除有听力损失和神经肌肉病变的参与者。对参与者进行Graybiel量表和cemp测试。比较各组cemp阈值、波潜伏期和振幅、耳间振幅不对称比（IAARs）。此外，还对晕机易感人群（AS）的IAAR与晕机严重程度的易感性进行了相关分析。结果：AS组右耳cemp阈值（85.62±6.05）低于对照组（91.16±4.85）；P < 0.001)。在100、95和90 dB nHL水平下，AS组右耳P1和N1潜伏期均短于对照组（p < 0.05）。同样，AS组右耳100 dB nHL时P1N1波幅值高于对照组（p = 0.009）。AS组IAAR高于对照组（p < 0.001）。AS组IAAR与晕机易感程度呈正相关（分别在100、95、90 dB nHL时ρ = 0.742、0.650、0.535）。结论：飞行员对晕机的易感性可能与cemp标准潜伏期和振幅的变化有关。本研究证明了囊状反射通路完整性的不对称性与飞行员晕机易感性的严重程度之间的相关性。在对晕机更敏感的受试者中，观察到较高的IAAR，表明这两个变量之间存在潜在的相关性。补充资料：https://doi.org/10.23641/asha.28300112。

期刊介绍： Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
