简介:目的考察音乐教育对3-4岁听障儿童听觉能力、言语能力发展的影响。方法将40名3-4岁语前聋儿童随机分成实验组和对照组,每组20人。在5个月内,实验组持续参加每周1次、每次1小时的音乐教育课程;对照组只接受常规的康复教育。采用《听障儿童听觉、言语能力测试表》测试两组被试在实验前后的听觉能力和言语能力。结果①在听觉能力、言语能力测试总分上,实验组和对照组的前测、后测成绩均没有显著差异;②在听觉能力测试中,实验组的各项后测成绩均显著高于其前测成绩,包括声母识别率(t=-4.736,P〈0.01)、韵母识别率(t=-3.603,P〈0.01)、双音节识别率(t=-3.432,P〈0.01)、短句识别率(t=-4.228,P〈0.01)、总分(t=-5.067,P〈0.01)。对照组只在声母识别率(t=-2.877,P〈0.05)、韵母识别率(t=-2.779,P〈0.05)及总分(t=-2。393,户〈0.05)3项上的后测成绩显著高于其前测成绩;③在言语能力测试中,实验组和对照组的各项后测成绩均显著高于其前测成绩,且实验组在主题对话部分的后测成绩显著高于对照组(t=-2.076,P〈0.05)。结论音乐教育是听障儿童康复训练中可以选择使用的一种康复方式,对听障儿童的听觉能力、言语能力发展有一定的帮助。
简介:目的:分析大前庭水管综合征(largevestibularaqueductsyndrome,LVAS)患者家系的SLC26A4基因突变方式并确定其是否致病。方法采集3个特殊LVAS家系的血样,测序分析SLC26A4基因型。采用在线软件SIFT、Polyphen-2预测这3个家系中所携带的罕见突变方式的致病性,利用排除法证明c.2343+69C>A的非致病性。结果共检出5种突变方式,其中4种为致病性基因突变。先证者基因型为IVS7-2A>G/c.1594A>C,IVS7-2A>G/c.1327G>C,IVS7-2A>G/c.1667A>G,均为LVAS。基因型为c.1594A>C/2343+69C>A,c.1327G>C/c.2343+69C>A,c.1667A>G/c.2343+69C>A的受检者听力正常。结论SLC26A4基因c.2343+69C>A突变方式是非致病的基因多态;3个家系先证者的父母再次妊娠出现聋儿的风险为25%。
简介:目的探索听障儿童精神发育规律及特点,为科学制订听障儿童康复策略及措施提供理论依据。方法采用格雷菲斯(Griffith)精神发育量表中运动、手眼协调、操作3个分测验对25个省308名0~3岁听障儿童进行精神发育评估,采用相同方法对14省473名0~3岁健听儿童进行测查,常模参照1995年修订标准,采用发育商=(发育年龄/实际年龄)×100表述精神发育水平,用成组比较啦验进行对比分析。结果①308名0~3岁听障儿童平均发育商为102.46±11.16,运动维度发育商为105.92±15.72、手眼协调维度发育商为100.84±11.99、操作维度发育商为101.02±14.29。473名健听儿童平均发育商为110.09±19.67,运动维度发育商为115.40±12.25、手眼协调维度发育商为108.84±23.34、操作维度发育商为106.03±21.98。听障儿童与健听儿童相比,总发育商低约8(t=-9.985,P=0.000)、运动维度低约10(f=-6.024,P=0.000)、手眼协调维度低约8(t=-5.825,P=0.000)、操作维度低约5(t=-3.603,P=0,000),差别均有统计学意义;②出生后到6个月,听障儿童与健听儿童精神发育无任何差别,从12个月龄开始,听障儿童精神发育逐渐落后于健听儿童,36个月龄时,落后近2个月龄;③无论听障儿童或健听儿童,不同性别发育商差别均无统计学意义。结论0~3岁听障儿童与健听儿童精神发育有一定差距,随年龄增加,差距逐渐明显。早期发现听力障碍,及时给予听力补偿或听力重建,优化听障儿童早期生活环境,提早进入科学规范的康复训练和教育程序,能为缩小听障儿童和健听儿童的智力差距打下良好基础。
简介:目的研究北京市听障儿童智力发育的特点,比较听障儿童与健听儿童智力发育的差别,为北京市听障儿童康复工作提供理论依据。方法采用希一内学习能力测验的健听常模对56名听障儿童和56名相同年龄的健听儿童的智力进行测验。结果3~7岁听障儿童的比率智商是94.99±14.27,56名健听儿童的比率智商是96.49±12.98,两者的差别没有统计学意义;4岁之前二者的智力水平发展一致,随着年龄的增加,二者的差距增大,差别无统计学意义。与健听儿童相比,听障儿童的手眼协调、空间知觉、视觉记忆和抽象思维发展较好,而色彩记忆和分析综合能力发展滞后。结论北京市听障儿童智力发育良好,已接近健听儿童的水平,社会和家庭应继续关注听障儿童的早期干预和心理健康,以期达到全面康复的目的。
