Abstract

Recent reports suggest that high frequency eye tremor or ocular microtremor (OMT) may be a useful indicator of brainstem function. The method of record analysis, and in particular the amount of record subjected to such analysis, has varied widely. We have recorded OMT from 10 normal subjects. Using these records we have performed 42 distinct replication reliability studies. We suggest seven parameters of OMT (including overall frequency of tremor) which may be of value in comparing abnormal with normal records. For each parameter we have determined the optimal duration of the record to analyse and the reliability of such analysis. Our results suggest that at least 5 s of OMT should be analysed to yield an acceptable estimate of all seven parameters.

高频眼震颤:测量的可靠性。

最近的报道表明，高频眼震颤或眼微颤(OMT)可能是脑干功能的一个有用指标。记录分析的方法，特别是进行这种分析的记录的数量，差别很大。我们记录了10名正常受试者的OMT。利用这些记录，我们进行了42项不同的复制可靠性研究。我们提出了七个参数(包括震颤的总频率)，这些参数在比较异常和正常记录时可能有价值。对于每个参数，我们都确定了要分析的记录的最佳持续时间和这种分析的可靠性。我们的结果表明，至少要分析5秒的OMT才能对所有7个参数产生可接受的估计。
