Aural rehabilitation focused on music for individuals with cochlear implants (CIs) and/or hearing aids (HAs) typically emphasizes perceptual skills rather than enjoyment of music. Yet, those with CIs and/or HAs often struggle to enjoy music, complaining that it sounds distorted with the implant or HAs. Typically, aural rehabilitation programs require a significant time commitment, but this may not be feasible or preferable for many patients. This study aimed to evaluate the efficacy of two individualized intensive 3-week home practice programs focused on enjoyment of music, a personal goal for this subject.
The subject was a professional musician who used a CI and HA. Cognitive measures of global cognitive function, executive function, processing speed, auditory working memory, visual-spatial abilities, verbal fluency, and auditory-verbal memory, as well as auditory electrophysiology (EEG) measures were conducted pre-post experiment 2. Two experiments were undertaken to evaluate responses to two practice programs that incorporated different variations in listening dosage and intervention activities.
Experiment 1 resulted in minimal measurable improvements related to music likability ratings, with the highest dosage condition showing a small increase in average likability rating from baseline to week 3. The results of experiment 2 revealed an improvement in likability ratings only when dosage steadily increased each week. The subject also reported improved mood and decreased frustration during weeks two and three of experiment 2. Finally, we found improvement pre-post experiment 2 on several cognitive and EEG measures.
The results of these experiments are encouraging and support the use of an individualized, person-centered, and semi-structured home practice program to increase music enjoyment and improve quality of life and auditory processing for individuals with hearing loss. Future studies should aim to increase sample size and explore pairing person-centered home practice programs with concurrent clinician-lead aural rehabilitation.
针对使用人工耳蜗（CI）和/或助听器（HA）的个体开展的以音乐为重点的听觉康复，通常强调感知技能而非对音乐的欣赏。然而，使用CI和/或HA的人往往难以欣赏音乐，抱怨通过植入物或HA听到的音乐声音失真。通常，听觉康复计划需要投入大量时间，但这对许多患者来说可能不可行或并非首选。本研究旨在评估两个为期3周的个性化强化家庭练习计划的效果，该计划侧重于将欣赏音乐作为该主题的个人目标。
受试者是一名使用CI和HA的专业音乐家。在实验2前后进行了全球认知功能、执行功能、处理速度、听觉工作记忆、视觉空间能力、语言流畅性和听觉语言记忆的认知测量，以及听觉电生理（EEG）测量。进行了两项实验，以评估对两个练习计划的反应，这两个计划在听力剂量和干预活动方面纳入了不同的变化。
实验1在音乐喜爱度评分方面的可测量改善极小，最高剂量条件下从基线到第3周平均喜爱度评分略有增加。实验2的结果表明，只有当剂量每周稳步增加时，喜爱度评分才会提高。受试者还报告说，在实验2的第2周和第3周，情绪有所改善，挫败感有所降低。最后，我们发现实验2前后在几项认知和EEG测量方面有所改善。
这些实验的结果令人鼓舞，并支持使用个性化、以人为本和半结构化的家庭练习计划来增加音乐欣赏度，并改善听力损失个体的生活质量和听觉处理能力。未来的研究应旨在增加样本量，并探索将以人为本的家庭练习计划与临床医生主导的同步听觉康复相结合。
