摘要
目的观察语后聋人工耳蜗植入者开机后安静环境中视听言语感知能力的变化情况,分析视觉言语信息在言语感知中的作用。方法评估12名(12~43岁)语后聋国产诺尔康人工耳蜗使用者开机后1、2、4、6个月时在安静环境中单一视觉、单一听觉和视听结合三种模式下的语句识别率。结果在开机后半年内,随着开机时间的延长,12名受试者在视听结合和单一听觉模式下,安静环境中语句识别率呈上升趋势,使用重复测量方差分析,两种模式下不同时间点测试结果之间的差异均有统计学意义(P<0.05),其中视听结合模式下开机后2月和4月时的测试平均分差异无统计学意义,单一听觉模式下,开机后4月和6月时测试平均分差异无统计学意义。单一视觉模式下,各个时间点的测试结果无明显变化,经重复测量方差分析,各个时间点测试结果的差异无统计学意义(P>0.05)。视听结合模式下各个时间点语句识别平均得分均明显高于单一视觉、单一听觉两种模式。结论语后聋人工耳蜗植入者在开机后半年内视听结合和单一听觉模式下的言语感知能力不断提高,单一视觉模式下的言语感知能力无明显变化;视觉言语信息对安静环境中的言语感知有较大帮助。
