Abstract

A wealth of information concerning the caloric test has accumulated since the test was introduced more than eight decades ago. Both convective and nongravity-dependent forces on endolymph are believed to underlie the response at the end-organ level. Higher-order influences are equally important and make the test findings highly dependent on specific test conditions. Slow-component eye velocity is the most widely accepted index of vestibular response, although success using nystagmus beat frequency has also been reported. Both bithermal and monothermal calorization sequences have been studied. Standardization of technique and a consensus on methods of interpretation will be necessary for the determination of the optimal clinical caloric test.

眼震电图中的热量测试。
自从80多年前引入热量测试以来,积累了大量关于热量测试的信息。内淋巴上的对流和非重力依赖力被认为是终末器官水平反应的基础。高阶影响同样重要,并使测试结果高度依赖于特定的测试条件。慢速成分眼速度是最被广泛接受的前庭反应指标,尽管也有报道成功地使用眼球震颤的节拍频率。研究了双热和单热化过程。技术的标准化和解释方法的共识对于确定最佳的临床热试验是必要的。
