The use of the MUSS and the SIR scale in late-implanted prelingually deafened adolescents and adults as a subjective evaluation

Abstract

Background: The SIR scale has been widely used to measure speech improvement in late-implanted prelingually deafened adolescents and adults. However the ceiling effect of the SIR scale may lead to the loss of some information.

Aim/objectives: To evaluate the oral ability of late-implanted prelingually deafened adolescents and adults using the MUSS and SIR scale and to analyse the relationship between the SIR score and the MUSS score.

Material and methods: Ninety-four prelingually deafened adolescents and adults who had received cochlear implants were investigated. The MUSS and SIR scale were used to evaluate oral ability.

Results: The relationship between the duration of implant use and the MUSS score was significantly different. No significant differences were found among the groups for age at implantation, gender and side of cochlear implantation. The total score on the MUSS was positively correlated with the SIR score.

Conclusions and significance: The MUSS and the SIR scale could be used to evaluate the oral ability of late implanted patients. The SIR scale could be used to perform a rapid assessment and the MUSS could help provide more information. The combination of the two scales could be used to evaluate vocal ability more accurately and effectively.

Chinese abstract

背景：SIR量表已被广泛用于测量较晚接受植入的语前失聪青少年和成人的语音改善。然而, SIR量表的上限效应可能导致一些信息的丢失。

目的：应用MUSS和SIR量表评价较晚接受植入的语前失聪青少年和成人的口语能力, 分析SIR评分与MUSS评分之间的关系。

材料与方法：对94例接受人工耳蜗植入术的语前失聪青少年和成人进行调查。用MUSS和SIR量表评定口语能力。

结果：植入体使用时间与MUSS评分的关系有显著性差异。人工耳蜗植入年龄、性别、侧位之间并无显著性差异。MUSS总分与SIR总分呈正相关。

结论及意义：MUSS和SIR评分可用于评价较晚植入患者的口语能力。SIR量表可用于进行快速评估, MUSS可帮助提供更多信息。两个量表的结合可以更准确、有效地评价发声能力。
