音乐音符训练提高人工耳蜗植入青少年音符听辨能力的临床研究

The clinical study on the efficiency of music training in improving the music perception ability of teenagers receiving cochlear implantation

目的探讨交互式的音乐音符训练是否能提升人工耳蜗植入青少年的音符听辨能力,进而提升其欣赏音乐的能力。方法 30例语前聋行人工耳蜗植入的青少年参加了这项试验,在音符听辨训练之前,先用QuickTest和QuickStar软件进行评估,评估后采用SOUNDANDBEYOND训练软件进行基准测试至少4次。之后所有试验者进行音符听辨训练,5d/周,练习30min/d(可分多次进行),持续4周,共训练600min。然后立即用QuickTest和QUICKSTAR软件进行评估,2月后再次进行一次评估。结果训练前受试者旋律轮廓识别正确率为(27±11)%,训练后受试者旋律轮廓识别正确率为(36±12)%,差异有统计学意义(P<0.01)。训练后双耳纯音听阈较训练前均减低,左耳差异有统计学意义(P<0.05),右耳差异无统计学意义(P>0.05)。结论交互式的音乐音符训练可以提升人工耳蜗植入青少年的音符听辨能力,进而提升他们欣赏音乐的能力;同时通过训练,应用人工耳蜗植入青少年的听力亦可得到提高。

Objective To observe weather the interactive music auditory training could improve the teenagers＇ music perception ability who use artificial cochlea. Methods 30 prelingual teenagers who used artificial cochlea were trained with interactive music auditory training （ recorded at House Ear Institute as part of the CAST program）. First, all the teenagers were evaluated by QUICKTEST and QUICKSTAR software, then the benchmark tests were conducted as baseline for at least 4 times by SOUND and BEYOND training software, next all the subjects were trained with music perception,30min a day,5 times a week for 4 weeks, with total training time of 600 min, immediately after the training the music perception abilities of the subjects were evaluated by QUICKTEST and QUICKSTAR software, and the evaluation was repeated after 2 months. Results Before the training the correct rate of melodic contour recognition in the subjects was（27 ± 11 ）%, however,which was （36 ± 12） % after training, and there was a significant difference before and after the training （ P 〈 0.01 ）. As compared with that before training, the pure tone auditory threshold of both ears was decreased after training, and there was a significant difference in the right ear （ P 〈 0.05 ）, but there was no significant difference in the left ear （ P 〉 0.05）. Conclusion The interactive music auditory training can improve music perception of the teenagers who receive cochlear implantation, as a result, which can increase their abilities for enjoying music, meanwhile, their audition can also be improved by the training.
