A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Databases were searched using a comprehensive search strategy including the terms \"Vibration-induced nystagmus\" or \"SVINT\" or \"skull vibration-induced nystagmus test\" or \"skull vibration-induced nystagmus\" from inception to May 2020.
A total of 79 articles were identified, and 16 studies met the inclusion criteria. The methodology for performing the SVINT and determining positivity is varied. Most authors refer to reproducibility, sustained response, ending with withdrawal of stimulus, nondirection changing, and response in more than one point of stimulation, as necessary for a positive test. Only seven studies included a slow phase velocity of 2 degrees/s or 2.5 degrees/s as a criterion. Most studies employed 100 Hz stimulus for 10 seconds, while longer duration is suggested for pediatric patients. For partial and total unilateral vestibular loss, positivity varied from 58 to 60%, and 93 to 100%, respectively. Sensitivity ranged from 50 to 100%, and specificity from 62 to 100%. Importantly, the SVINT may decrease with time but does not usually disappear, hence, can provide information of past/compensated vestibular events.
The SVINT can be used in pediatric and adult patients. It provides information regarding unilateral vestibular loss, acute, or compensated. It is a quick, safe, and noninvasive test, and is complementary to the dynamic vestibular and positional tests.

根据系统评价和荟萃分析指南的首选报告项目进行系统评价。从开始到2020年5月,使用全面的搜索策略搜索数据库,包括术语“振动诱发的眼球震颤”或“SVINT”或“颅骨振动诱发的眼球震颤测试”或“颅骨振动诱发的眼球震颤”。
共确定了79篇文章,16项研究符合纳入标准.用于执行SVINT和确定阳性的方法是变化的。大多数作者提到可重复性,持续的反应,以退出刺激计划结束,无方向改变,在不止一个刺激点的反应,作为一个积极的测试所必需的。只有7项研究包括2度/s或2.5度/s的慢相速度作为标准。大多数研究使用100赫兹刺激10秒,而对于儿科患者建议持续时间更长。对于部分和全部单侧前庭丢失,积极性从58%到60%不等,93%到100%,分别。灵敏度范围从50%到100%,特异性从62%到100%。重要的是,SVINT可能会随着时间的推移而减少,但通常不会消失,因此,可以提供过去/代偿性前庭事件的信息。
SVINT可用于儿科和成人患者。它提供了有关单侧前庭丢失的信息,急性,或补偿。这是一个快速的,安全,和非侵入性测试,并且是动态前庭和位置测试的补充。
