Studies of the audiospinal effect on the H-reflex demonstrated that in normal test subjects and in patients with injuries to the spinal cord coupled with parapareses and in part of patients with paraplegia of the lower limbs, there was a sound-induced 30-70% increase in the amplitude of the H-reflex. As the interval between the conditioning sound and testing electric stimulations was raised, two maxima of the increment of the H-reflex amplitude within 30-40 ms and 80-100 ms were revealed. The increased H-response within these intervals seems likely to be connected with the conduction of excitation from the brain cortex via the pyramidal tract and the reticulospinal tract. Part of the patients with spinal cord injuries and paraplegia of the lower limbs did not manifest any sound-induced increase in the H-reflex. Apparently, such lack of increase is either a consequence of the functional blockade of the afferent conduction tract or that of their anatomical disturbance. The method of the audiospinal effect on the H-reflexes may be used for diagnostic purposes, namely for the determination of the conduction via the afferent cerebrospinal tract.
对H反射的听觉脊髓效应的研究表明，在正常测试对象、伴有截瘫的脊髓损伤患者以及部分下肢截瘫患者中，声音可使H反射的幅度增加30%至70%。随着条件声音与测试电刺激之间的间隔增加，在30至40毫秒和80至100毫秒内发现了H反射幅度增加的两个最大值。这些间隔内H反应的增加似乎与兴奋从大脑皮层通过锥体束和网状脊髓束的传导有关。部分脊髓损伤和下肢截瘫患者未表现出任何声音诱发的H反射增加。显然，这种增加的缺乏要么是传入传导束功能阻断的结果，要么是其解剖结构紊乱的结果。对H反射的听觉脊髓效应方法可用于诊断目的，即用于确定通过传入脑脊髓束的传导。
