This study investigated the development of aided long-latency response (ALLR) in children with cochlear implants (CI) within 18 months of implantation.
ALLR was recorded in 33 children with CI who had an experience of less than 18 months with the implant. All the participants were in the age range of 3-7 years and were divided into 3 groups based on implant age, as 0-6 months, 6.1-12 months, and 12.1-18 months. Latency of the P1 component was recorded.
P1 latency was observed to be 142.105 ms at 0-6 months of implant age, 135.141 ms at 6.1-12 months of implant age, and 122.952 ms. at 12.1-18 months of implantation. CI recipients require 1 year of experience in order to obtain a significant difference in the P1 latency value. It was also found that gender does not influence P1 latency.
These preliminary findings suggest that with adequate stimulation, there is a gradual decrease in P1 latency, which indicates maturation of the central auditory structures. It was also found that the gender does not influence P1 latency.
本研究调查了人工耳蜗植入（CI）儿童在植入后18个月内辅助长潜伏期反应（ALLR）的发展情况。
记录了33名人工耳蜗植入时间少于18个月的儿童的ALLR。所有参与者年龄在3至7岁之间，根据植入年龄分为3组，即0至6个月、6.1至12个月和12.1至18个月。记录P1成分的潜伏期。
在植入年龄0至6个月时，观察到P1潜伏期为142.105毫秒，在6.1至12个月时为135.141毫秒，在12.1至18个月时为122.952毫秒。人工耳蜗接受者需要1年的使用经验才能在P1潜伏期值上获得显著差异。还发现性别不影响P1潜伏期。
这些初步研究结果表明，在适当刺激下，P1潜伏期逐渐缩短，这表明中枢听觉结构成熟。还发现性别不影响P1潜伏期。
