Effect of socalled tonic reflexes on central processing of acoustic stimuli was studied by stimulating the patterns of tonic reflexes in 18 adults with normal hearing abilities. The parameters were: hearing threshold level, acoustical stapedius reflex and slow auditory evoked potential. Only in three positions-corresponding to the symmetrical tonic neck reflex (STNR) and tonic labyrinthine reflex in supine and prone position a hearing threshold shift of 1 dB could be observed. The level of the stapedius reflex showed an increase of 5 dB in one of these three positions. In the acoustical evoked slow potential only the amplitude but not the latency was influenced. In some cases we found an increase of amplitude, in others a decrease or even a complete suppression. In using ERA to evaluate possible auditory disturbances in children with cerebral palsy it seems necessary to consider these possible influences on the evoked potential.
通过刺激18名听力正常的成年人的紧张性反射模式，研究了所谓的紧张性反射对听觉刺激中枢处理的影响。参数包括：听力阈值水平、镫骨肌声反射和慢听觉诱发电位。仅在三个位置——对应于仰卧位和俯卧位的对称紧张性颈反射（STNR）和紧张性迷路反射——可观察到1 dB的听力阈值变化。在这三个位置中的一个位置，镫骨肌反射水平增加了5 dB。在听觉诱发慢电位中，仅振幅受到影响，潜伏期未受影响。在某些情况下，我们发现振幅增加，在其他情况下则减少甚至完全抑制。在使用听觉脑干反应（ERA）评估脑瘫儿童可能存在的听觉障碍时，似乎有必要考虑这些对诱发电位的可能影响。
