To investigate the relationship between single-channel and banded neural response imaging (NRI) responses and to evaluate whether banded NRI measurements are better correlated to fitting parameters than single-channel NRI measurements.
Nineteen profoundly deaf subjects implanted with a HiRes 90K cochlear implant from Advanced Bionics Corporation (Valencia, CA).
INTERVENTION(S): Neural response imaging thresholds (tNRIs; single-channel and banded tNRIs) were measured intraoperatively; at first fitting; and after 3, 6, and 12 months of implant use. Relationships between those measurements and correlations between those measurements and implant program parameters were investigated.
MAIN OUTCOME MEASURE(S): Single-channel and banded tNRI collected at each measurement session.
Banded NRI could be recorded reliably and was not more time-consuming than the routine single-channel NRI. Significant correlations (Pearson R; p < 0.05) were observed between first-fitting banded tNRI and most comfortable levels at 12 months, with a higher level of significance than the correlations observed with single-channel tNRI.
Banded NRI may be a more appropriate fitting tool than single-channel NRI. However, the sample size was small, and more data are necessary to confirm these findings.
研究单通道与带状神经反应成像（NRI）反应之间的关系，并评估带状NRI测量值与拟合参数的相关性是否优于单通道NRI测量值。
19名植入了先进生物电子公司（加利福尼亚州瓦伦西亚）HiRes 90K人工耳蜗的极重度聋患者。
术中、初次调试时以及植入使用3个月、6个月和12个月后测量神经反应成像阈值（tNRI；单通道和带状tNRI）。研究这些测量值之间的关系以及这些测量值与植入程序参数之间的相关性。
在每个测量阶段收集的单通道和带状tNRI。
可以可靠地记录带状NRI，且不比常规单通道NRI耗时更多。初次调试时的带状tNRI与12个月时的最舒适响度级之间观察到显著相关性（Pearson相关系数R；p<0.05），其显著程度高于单通道tNRI观察到的相关性。
带状NRI可能是比单通道NRI更合适的调试工具。然而，样本量较小，需要更多数据来证实这些发现。
