OBJECTIVE
This study aimed to characterise the ipsilateral, contralateral and bilateral masseter vestibular-evoked myogenic potential using clicks and 500 Hz tone burst stimuli in healthy adults.
METHOD
Masseter vestibular-evoked myogenic potential was recorded from 20 healthy participants aged 19-28 years (11 males and 9 females). Masseter vestibular-evoked myogenic potential was recorded using 500 Hz tone burst and click stimuli in ipsilateral, contralateral and bilateral modes.
RESULTS
A statistically significant difference was observed between ipsilateral and contralateral stimulation for p11 latency, n21 latency and p11-n21 amplitude for both click and 500 Hz tone burst stimuli. The amplitude of the p11-n21 complex was higher for ipsilateral, contralateral and bilateral stimulations for 500 Hz tone burst than for click stimulus.
CONCLUSION
This study showed a significant difference for p11-n21 amplitude between click and 500 Hz tone burst evoked masseter vestibular-evoked myogenic potential. In addition, bilateral stimulation elicited a larger response than ipsilateral and contralateral stimulation.
目的
本研究旨在描述健康成年人使用 click 和 500 Hz 短音刺激时，同侧、对侧和双侧咬肌前庭诱发肌源性电位的特征。
方法
采用 500 Hz 短音和 click 刺激，在 19-28 岁的 20 名健康参与者（男性 11 名，女性 9 名）中记录咬肌前庭诱发肌源性电位。
结果
click 和 500 Hz 短音刺激的同侧和对侧刺激之间，p11 潜伏期、n21 潜伏期和 p11-n21 振幅均存在统计学显著差异。500 Hz 短音刺激的 p11-n21 复合波振幅大于 click 刺激。
结论
本研究表明，click 和 500 Hz 短音诱发的咬肌前庭诱发肌源性电位的 p11-n21 振幅存在显著差异。此外，双侧刺激比同侧和对侧刺激引起的反应更大。
