In many clinics and medical offices the electrographical registrations of vestibular reactions are only available for patients with special problems. For routine explorations Frenzel's glasses are still in use. It was one purpose of our studies to show that the observation with Frenzel's glasses is no less effective than ENG registration, in regard to nystagmus frequency. This result is based on investigations with special equipment for simultaneous registration and computerized evaluations. The disadvantage using Frenzel's glasses without any other equipment is the impossibility of determining the culmination phase exactly. Therefore we looked for a defined period in which the frequency was correlated best to the frequency of the culmination phase determined by ENG recordings. A total of more than 100 different intervals were analyzed. The optimal period for routine investigations is a 1 min interval beginning 10 sec after the end of irrigation. Limiting the evaluation of a caloric response to this defined observation period is recommended for various reasons.
在许多诊所和医疗办公室，前庭反应的电图记录仅适用于有特殊问题的患者。对于常规检查，仍在使用弗伦泽尔眼镜。我们研究的一个目的是表明，就眼球震颤频率而言，使用弗伦泽尔眼镜进行观察的效果并不亚于眼震电图记录。这一结果是基于使用特殊设备进行同步记录和计算机评估的调查得出的。不使用任何其他设备而仅使用弗伦泽尔眼镜的缺点是无法精确确定峰值阶段。因此，我们寻找了一个确定的时间段，在此期间，频率与通过眼震电图记录确定的峰值阶段的频率相关性最佳。总共分析了100多个不同的间隔。常规检查的最佳时间段是冲洗结束后10秒开始的1分钟间隔。出于各种原因，建议将冷热试验反应的评估限制在这个确定的观察期内。
