Computer-based auditory training (CBAT) has been shown to improve outcomes in adult cochlear implant (CI) users. This study evaluates in new CI users whether starting CBAT within 3 months of activation or later impacts CI outcomes.
Prospective natural experiment.
Tertiary academic medical center.
Sixty-five new adult CI users.
CBAT use over the first-year postactivation.
Speech recognition scores and CIQOL-35 Profile score improvements between CI recipients who started CBAT resources early (<3 mo) and late (3-12 mo) postactivation.
A total of 43 CI recipients started using CBAT within 3 months postactivation (early) and 22 after 3 months (late). Patients who used CBAT within 3 months postactivation showed significantly greater improvement in consonant-nucleus-consonant words (CNCw) (48.3 ± 24.2% vs 27.8 ± 24.9%; d = 0.84), AzBio Sentences in quiet (55.1 ± 28.0% vs 35.7 ± 36.5%; d = 0.62), and CIQOL-35 listening domain scores (18.2 ± 16.3 vs 6.9 ± 12.9, d = 0.73 [0.023, 1.43]), at 3 months postactivation, compared to those who had not yet initiated CBAT. However, by 12 months postactivation, after which all CI recipients had started CBAT, there were no differences observed between patients who started CBAT early or late in speech recognition scores (CNCw: d = 0.26 [-0.35, 0.88]; AzBio: d = 0.37 [-0.23, 0.97]) or in any CIQOL global or domain score (d-range = 0.014-0.47).
Auditory training with self-directed computer software (CBAT) may yield speech recognition and quality-of-life benefits for new adult CI recipients. While early users showed greater improvement in outcomes at 3 months postactivation than users who started later, both groups achieved similar benefits by 12 months postactivation.
已证实基于计算机的听觉训练（CBAT）可改善成人耳蜗植入（CI）使用者的结果。本研究评估了新的 CI 用户中，激活后 3 个月内开始 CBAT 或更晚开始对 CI 结果的影响。
前瞻性自然实验。
三级学术医疗中心。
65 名新的成年 CI 用户。
激活后第一年期间的 CBAT 使用情况。
CI 接受者中，在激活后 3 个月内（早期）和 3-12 个月后（晚期）开始使用 CBAT 资源的患者之间的言语识别分数和 CIQOL-35 概况评分的改善。
共有 43 名 CI 接受者在激活后 3 个月内（早期）开始使用 CBAT，22 名在 3 个月后（晚期）开始使用。在激活后 3 个月内使用 CBAT 的患者在辅音-核-辅音词（CNCw）（48.3 ± 24.2%比 27.8 ± 24.9%；d = 0.84）、AzBio 安静句子（55.1 ± 28.0%比 35.7 ± 36.5%；d = 0.62）和 CIQOL-35 听力域评分（18.2 ± 16.3%比 6.9 ± 12.9%，d = 0.73 [0.023, 1.43]）方面的改善显著更大，而那些尚未开始 CBAT 的患者。然而，在激活后 12 个月时，所有 CI 接受者都开始使用 CBAT，在言语识别评分（CNCw：d = 0.26 [-0.35, 0.88]；AzBio：d = 0.37 [-0.23, 0.97]）或任何 CIQOL 整体或域评分方面，早期或晚期开始 CBAT 的患者之间均未观察到差异（d 范围= 0.014-0.47）。
使用自我指导的计算机软件（CBAT）进行听觉训练可为新的成年 CI 接受者提供言语识别和生活质量益处。虽然早期使用者在激活后 3 个月时的结果改善大于后期使用者，但两组在激活后 12 个月时都获得了相似的益处。
