This study examines the relationship of time to cochlear implant patient performance and the effect of device design on patient performance over time. Data were collected for patients who were implanted with Nucleus 22, Smith & Nephew Richards Ineraid, or 3M/Vienna cochlear implants as part of the Veterans Administration study on cochlear implants. Patients were administered a comprehensive audiological test battery prior to implantation, at stimulation, and 3 months, 1 year, and 2 years poststimulation. Results show that patient performance improved over the course of the study, with performance levels with each multichannel implant being similar at the study end point. The Nucleus device produced maximum performance sooner than the Ineraid device did, and performance of the single-channel 3M was consistently below that of the multichannel devices.
本研究探讨了时间与人工耳蜗植入患者表现之间的关系，以及随着时间推移设备设计对患者表现的影响。作为退伍军人管理局人工耳蜗植入研究的一部分，收集了接受Nucleus 22、施乐辉·理查兹Ineraid或3M/维也纳人工耳蜗植入患者的数据。在植入前、刺激时以及刺激后3个月、1年和2年，对患者进行了全面的听力学测试。结果表明，在研究过程中患者表现有所改善，在研究终点时，每种多通道植入设备的表现水平相似。Nucleus设备比Ineraid设备更快达到最佳表现，单通道3M设备的表现始终低于多通道设备。
