方法研究对象为20例先天性耳聋婴儿，其中2例在1岁6个月时因脑膜炎致聋。所有受试者的听力水平均被诊断为重度或完全耳聋。他们佩戴了助听器，并在聋人幼儿园接受了培训，但没有发展出听觉/语言交流能力。受试者植入人工耳蜗时的年龄在 2 岁至 7 岁 4 个月之间。表 1 总结了婴儿的特征。他们都佩戴了采用 SPEAK 策略的 Nucleus 设备。在我们的中心，通常只测量阈值水平，以保护婴儿在第一次映射期间免受过度刺激，并将舒适水平设置为高于阈值水平 20-30 的“刺激水平”。当婴儿似乎习惯听声音时，就可以评估舒适程度。舒适度评估的时间段因婴儿而异，但大多数婴儿为1个月至4个月。母亲必须参与适应训练，因为预计母亲与婴儿积极互动的方式，包括使用“母亲语”，可以为婴儿提供听觉/语言交流的动力。母亲关于婴儿在家中言语表现的报告对工作人员很有帮助，并且可能反映出一种新的培训方法。
MethodThe subjects were 20 congenitally deaf infants except 2, who were both deafened due to meningitis at 1 year 6 months. Hearing levels of all subjects were diagnosed as being profoundly or completely deaf. They had worn hearing aids and were trained in the nursery school for the deaf, but did not develop auditory/verbal communication. The ages of the subjects were between 2 years and 7 years 4 months at the time of cochlear implantation. Infant characteristics are summarized in table 1. All of them wore the Nucleus device with the SPEAK strategy.In our center, usually only threshold levels are measured to protect the infant from overstimulation during the first mapping, and the comfortable level is set at the ‘stimulus level’of 20–30 above the threshold level. The comfortable level is evaluated, when the infant seems to get used to listening to sounds. The period of comfortable level evaluation varies from one infant to the next, but it was from 1 month to 4 months for most infants. The mother must be included in habilitation, as it is anticipated that the mother’s style of active interaction with the infant, involving the use of ‘motherese’can provide the infant’s motivation for auditory/verbal communication. The mother’s reports on the infant’s speech performance in the home are helpful to the staff and may reflect a new approach of training.
