背景:前庭功能障碍是在神经和耳科环境中经常遇到的一种使人衰弱的疾病。前庭系统是外周和中枢机制之间的复杂网络。前庭系统的这种固有复杂性需要用于基于证据的诊断配方和干预的客观测试程序。客观测试有助于评估周围和中央前庭病变。为这些客观测试建立和提供全面的规范数据对于临床医生和研究人员都至关重要。
方法:这是一项前瞻性研究,涉及120名年龄在18至55岁之间的参与者(男性和女性)。所有参与者都是右撇子个体,没有明显的病史。在预先设定的协议上,cVEMP(宫颈前庭诱发肌源性电位),oVEMP(眼前庭诱发肌源性电位),vHIT(视频头脉冲测试),和VNG(视频眼震描记术)完成。
结果:虽然所有参与者(n=120)都接受了cVEMP,oVEMP,vHIT,扫视,顺利的追求,和光动力学测试,只有109名参与者同意热量测试。每个测试的平均值,标准偏差,中位数,四分位数,并记录了第三个四分位数。左右比较在cVEMP上没有显着差异,oVEMP,热量测试,顺利的追求,和光动力学测试。然而,很少有vHIT和扫视参数确实显示出显著差异。
结论:本研究提供了cVEMP的全面规范数据,oVEMP,vHIT,VNG的热量测试,和动眼测试(平稳追踪,扫视,视动)在VNG上。测试结果与先前公布的数据一致。vHIT中右侧和左侧之间的显着差异可能是因为用于测试的单眼护目镜。
结论:这项研究为年龄在18-55岁之间的个体提供了各种前庭测试的规范数据。这些信息可以帮助临床医生和研究人员在前庭科学领域工作。
BACKGROUND: Vestibular dysfunction is a debilitating disorder frequently encountered in neurological and otological settings. The vestibular system is a complex network between peripheral and central mechanisms. This innate complexity of the vestibular system necessitates objective test procedures for evidence-based diagnostic formulations and intervention. Objective tests aid in the evaluation of both peripheral and central vestibular pathologies. Establishing and availability of comprehensive normative data for these objective tests is crucial for clinicians and researchers alike.
METHODS: This is a prospective study involving 120 participants (both males and females) aged between 18 and 55 years. All participants were right-handed individuals and had no significant medical history. On pre-set protocols, cVEMP (cervical vestibular evoked myogenic potential), oVEMP (ocular vestibular evoked myogenic potential), vHIT (video head impulse test), and VNG (videonystagmography) were done.
RESULTS: While all participants (n=120) underwent cVEMP, oVEMP, vHIT, saccade, smooth pursuit, and optokinetic tests, only 109 participants consented to the caloric test. Each test\'s mean, standard deviation, median, quartile, and third quartiles have been recorded. A right-left comparison yielded no significant difference on cVEMP, oVEMP, caloric test, smooth pursuit, and optokinetic test. However, few vHIT and saccade parameters did reveal significant differences.
CONCLUSIONS: This study presents comprehensive normative data for cVEMP, oVEMP, vHIT, caloric test on VNG, and oculomotor tests (smooth pursuit, saccade, optokinetic) on VNG. The test results were in concordance with previously published data. The significant difference between the right and left sides in vHIT may be because of the monocular goggles used for the testing.
CONCLUSIONS: This study brings out the normative data for various vestibular tests on individuals aged between 18-55 years. This information could aid both clinicians and researchers working in the field of vestibular science.
