This study examined the effects of age at implantation on the development of communication abilities in children with early implantation. The 73 participants were prelingually deafened, received a cochlear implant before 5 years of age, and used current cochlear implant technology. The children were administered a battery of speech and language outcome measures before implantation and again at successive 6-month postimplant intervals. A mixed model analysis was used to examine the rate of growth in word recognition and language skills as a function of age at time of implantation. The results revealed significant improvements in communication skills over time. Spoken word recognition improved at a faster rate in the oral children with early implantation. However, the children who underwent implantation before 3 years of age had significantly faster rates of language development than did the children with later implantation. The oral children demonstrated more rapid gains in communication abilities than did the children who used total communication.
本研究考察了植入年龄对早期植入人工耳蜗儿童沟通能力发展的影响。73名参与者为语前聋患者，在5岁前接受了人工耳蜗植入，并使用了当前的人工耳蜗技术。这些儿童在植入前以及植入后连续的6个月间隔期接受了一系列言语和语言结果测量。采用混合模型分析来检验单词识别和语言技能的增长速度与植入时年龄的函数关系。结果显示，随着时间推移，沟通技能有显著改善。早期植入人工耳蜗的口语儿童的口语单词识别能力提高得更快。然而，3岁前接受植入的儿童的语言发展速度明显快于植入时间较晚的儿童。与使用全沟通方式的儿童相比，口语儿童在沟通能力方面取得了更快的进步。
