Abstract

The variability of the auditory brainstem response (ABR) to bone- and air-conducted clicks was investigated utilizing a test-retest paradigm with 20 normal full-term newborn infants. ABRs to bone-conducted clicks at 15 and 30 dB nHL and air-conducted clicks at 30 dB nHL were obtained. The delivery of the bone-conducted signal was controlled. ABR wave V latencies were measured from each test-retest stimulus condition. The results indicated no statistically significant difference in test-retest variability of ABR wave V latencies or amplitudes between bone- and air-conducted clicks. ABRs to bone-conducted clicks, under controlled clinical conditions, are as reproducible and reliable as ABRs to air-conducted clicks in newborn infants.

摘要

利用重测范式对20名正常足月新生儿进行研究，以探讨听性脑干反应（ABR）对骨导和气导短声的变异性。分别获得了15 dB nHL和30 dB nHL骨导短声以及30 dB nHL气导短声的ABR。骨导信号的传递是可控的。从每次重测刺激条件下测量ABR波V潜伏期。结果表明，骨导和气导短声的ABR波V潜伏期或波幅在重测变异性方面无统计学显著差异。在可控的临床条件下，新生儿对骨导短声的ABR与对气导短声的ABR一样具有可重复性和可靠性。
