Computerised evaluation of tensor muscle reaction was carried out by using a biosignal analysing unit triggered by nasal inhalation. The trigeminus nerve was stimulated by application of 3-molar acetylacetic acid into the nasal respiratory air, inducing a contraction of the tympanic muscle, followed by a change in impedance. This change in impedance of the tympanic membrane ossicle system was recorded and printed out on a display. In this manner evidence was obtained of a tensor muscle reaction induced by the third branch of the trigeminal nerve as efference, and demonstrated for the first time. This reflex arc had long been considered as being of negligible clinical importance before its stimulation and measurement had become possible. It is a generally accepted theory that the reflex arc of the m. tensor tympani is linked to the formatio reticularis which assesses the sensory afferences. For this reason, the reflex arc habituates rapidly, and continuous stimulation is no longer possible.
通过使用由鼻吸气触发的生物信号分析单元对鼓膜张肌反应进行计算机化评估。通过将3摩尔乙酰乙酸应用于鼻腔呼吸空气来刺激三叉神经，诱发鼓膜肌收缩，随后阻抗发生变化。记录鼓膜听小骨系统的这种阻抗变化并在显示器上打印输出。通过这种方式，首次获得了由三叉神经第三分支诱发的鼓膜张肌反应作为传出神经的证据。在其刺激和测量成为可能之前，这个反射弧长期以来一直被认为在临床上重要性可忽略不计。普遍接受的理论是，鼓膜张肌的反射弧与评估感觉传入的网状结构相连。因此，反射弧会迅速习惯化，不再可能进行持续刺激。
