最近开发的Radioear B81骨振荡器允许更高的骨传导振动输出;然而，缺乏关于其在前庭诱发肌源性电位（VEMP）测试中使用的规范性数据。本研究的目的是检查年龄对颈部和眼部VEMP（c-和oVEMP）反应的影响，并比较空气传导刺激（ACS）和脉冲锤（IH）VEMP反应特征。在健康受试者（年龄范围= 10-87岁，n = 85）中使用ACS、B81和IH刺激完成c-和oVEMP。无论刺激类型，c-和oVEMP振幅和反应率随年龄的增长而下降。对于cVEMP缓解率，ACS的表现优于或等于B81，上级IH。对于cVEMP校正振幅，ACS的振幅显着高于B81和IH。B81和IH的cVEMP校正幅度无差异。对于oVEMP，反应率在刺激之间具有可比性，其中最大的反应率差异发生在最老的组中，其中IH优于ACS和B81。对于oVEMP振幅，IH的振幅显著高于B81和ACS。B81和ACS的oVEMP振幅无差异。年龄显着影响c和oVEMP振幅，无论刺激类型（ACS，B81，IH）。所有刺激都适合于在年轻个体中诱发c-和oVEMP。虽然ACS导致更高的cVEMP校正振幅，但ACS或B81均适用于老年人。然而，对于oVEMPs，IH的应答率更高，振幅更大，其次是B81和ACS。总体而言，B81在c-和oVEMP的整个生命周期内表现良好，可能是ACS VEMP缺失患者的合理BCV选择，但目前不建议作为ACS的替代品。
Recently developed, the Radioear B81 bone oscillator allows for higher bone conduction vibration output; however, normative data is lacking regarding its use in vestibular evoked myogenic potential (VEMP) testing. The purpose of this study was to examine the effect of age on cervical and ocular VEMP (c- and oVEMP) responses using the B81 and to compare to air-conduction stimuli (ACS), and impulse hammer (IH) VEMP response characteristics. c- and oVEMP were completed with ACS, B81, and IH stimuli in healthy participants (age range = 10-87 years, n = 85). Regardless of stimulus type, c- and oVEMP amplitudes and response rates decreased with age. For cVEMP response rates, ACS performed better or equal to B81, which was superior to the IH. For cVEMP corrected amplitude, ACS had significantly higher amplitudes compared to B81 and IH. There was no difference in cVEMP corrected amplitude between B81 and IH. For oVEMP, response rates were comparable between stimuli with the largest disparity in response rates occurring in the oldest groups where IH outperformed both ACS and B81. For oVEMP amplitude, IH had significantly higher amplitudes compared to B81 and ACS. There was no difference in oVEMP amplitude between B81 and ACS. Age significantly affected c- and oVEMP amplitudes regardless of stimulus type (ACS, B81, IH). All stimuli are appropriate for eliciting c- and oVEMP in the young individuals. While ACS resulted in higher cVEMP corrected amplitudes, either ACS or B81 are appropriate for older individuals. However, for oVEMPs, higher response rates and larger amplitudes were noted for IH followed by B81 and ACS. Overall, the B81 performed well across the lifespan for c- and oVEMPs and may be a reasonable BCV option for patients with absent ACS VEMPs, but at this time is not recommended as a replacement to ACS.
