The procedures for conducting and interpreting Stapedial Reflex Decay (SRD) are discussed. A modification of currently used procedures and interpretations in which testing is conducted at 750 and 1500 Hz as well as 500, 1000 and 2000 Hz is also discussed. Abnormal decay is defined as fatigue to half-life in less than 6.2 seconds. The SRD test patterns of 464 ears with cochlear lesions and 68 ears with retrocochlear lesions are presented and discussed. The findings are strongly supportive of SRD testing using the proposed procedures and interpretations.
本文讨论了镫骨肌反射衰减（SRD）测试及结果解读的流程。同时也探讨了对当前使用流程和解读方式的一种改进，即在500、1000、2000赫兹以及750和1500赫兹进行测试。异常衰减定义为在不到6.2秒的时间内疲劳至半衰期。文中展示并讨论了464例耳蜗病变耳朵和68例蜗后病变耳朵的SRD测试模式。这些发现有力地支持了使用所提出的流程和解读方式进行SRD测试。
