Seventeen adult subjects participated in a multicentre trial to compare the performance between an NRT-based MAP and their behavioural MAP. The NRT-based MAP was made using a correction factor to predict T/C levels, calculated from the difference between the ECAP threshold ('T-NRT') and the measured T/C levels at electrode 10, as described by Brown et al. (2000). A secondary aim was to compare T/C levels in behavioural MAPs at different stimulation rates with the predicted T/C levels in NRT-based MAPs. Performance with both MAPs was evaluated using CNC words and sentences. Variations in the T/C levels between all MAPs were found, although results of the speech discrimination tests demonstrated no statistically significant difference between behavioural and NRT-based MAPs.
17名成年受试者参与了一项多中心试验,以比较基于NRT的言语听觉评估图谱(MAP)与行为学言语听觉评估图谱之间的性能。基于NRT的言语听觉评估图谱是使用一个校正因子来预测T/C水平制作而成的,该校正因子根据听性脑干反应(ECAP)阈值(“T-NRT”)与电极10处测得的T/C水平之间的差异计算得出,如Brown等人(2000年)所述。第二个目的是比较不同刺激率下行为学言语听觉评估图谱中的T/C水平与基于NRT的言语听觉评估图谱中预测的T/C水平。使用CNC单词和句子对两种言语听觉评估图谱的性能进行了评估。尽管言语辨别测试结果表明行为学言语听觉评估图谱与基于NRT的言语听觉评估图谱之间没有统计学上的显著差异,但在所有言语听觉评估图谱之间均发现T/C水平存在差异。
