【摘要】：目的:探索语前聋儿童人工耳蜗植入术后早期词汇能力的发展,同时探讨现行中文听障儿童语言能力测试工具的可行性。方法:56例重度-极重度语前聋婴幼期患儿参与该研究,使用普通话汉语沟通发展量表(CCDI)、普通话表达与理解词汇量测试(MERVT)等词汇量测评工具,由专业人员对患儿术后的词汇量进行评估。由患儿家长或监护人填写评估问卷;词汇量测试由患儿在评估人员陪同下进行测试。分别在术前和开机后3个月、6个月、1年及2年时对患儿进行评估。评估人员记录测试结果并进行统计学分析。结果:术后早期词汇量的发展随患儿康复时间延长而逐步提高。人工耳蜗植入儿童术后词汇能力不断提高,表现为理解性词汇先于表达性词汇发展。结论:耳蜗植入术后2年,儿童即发展出一定的词汇能力,人工耳蜗植入后儿童的词汇理解能力要先于表达能力的发展。CCDI及MERVT是评估人工耳蜗植入后患儿早期词汇能力的可用工具,词汇能力测试是评估人工耳蜗植入后儿童语言发展的重要指标,可与言语识别评估工具一道,共同构成一个完整的人工耳蜗植入后中国儿童听觉-言语-语言能力的评估体系。
[Abstract]:Objective: to explore the development of lexical ability in children with prelingual deafness after cochlear implantation. Methods 56 children with severe to very severe prelingual deafness were enrolled in the study. They were measured with CCDI and MERVT. The vocabulary of children after operation was evaluated by professionals. Parents or guardians fill out the assessment questionnaire; the vocabulary test is carried out by the child accompanied by the evaluator. The children were evaluated before operation and 3 months, 6 months, 1 year and 2 years after the operation. Assessors record test results and perform statistical analysis. Results: the development of vocabularies increased gradually with the prolongation of rehabilitation time. After cochlear implantation, the vocabulary ability of the children was improved continuously, which showed that the understanding vocabulary developed before the expressive words. Conclusion: two years after cochlear implantation, children developed certain lexical abilities. The vocabulary comprehension ability of children after cochlear implantation is prior to the development of expression ability. CCDI and MERVT are useful tools to evaluate the early lexical ability of children after cochlear implantation. Vocabulary competence test is an important index to evaluate the language development of children after cochlear implantation. It can be combined with speech recognition evaluation tools to form a complete evaluation system of hearing speech language ability of Chinese children after cochlear implantation.
