Abstract

Purpose: There is currently no consensus regarding an evidence-based assessment protocol for normal-hearing patients with a history of brain injury who report auditory difficulties. This work used a large test battery to identify measures that explained the most variability across participants with and without a history of head injury, to determine relationships between measures, and to explore patterns of performance across participants, with the aim of identifying measures that should be considered in future research on developing clinical assessment protocols for this unique patient population.

Method: A principal component analysis was conducted on data from 22 self-report, central auditory processing, and cognitive processing measures completed by a sample of 95 participants. Participants included Veterans with a history of blast exposure, Veterans with a history of nonblast mild traumatic brain injury (mTBI), and a sample of control participants with no history of head injury.

Results: Several central auditory processing and self-report measures explained variance in the data set. However, analyses revealed that performance on the behavioral auditory processing tests was not predictive of self-reported auditory and non-auditory symptom severity. A cluster analysis further revealed spread in performance across participants with a history of blast exposure or nonblast mTBI.

Conclusions: Results from the current study underscore the need for a comprehensive, individualized approach to patient care for those with a history of head injury. The measures identified in the current analysis should be investigated in future studies that aim to develop an auditory assessment protocol for this patient population.

创伤性脑损伤退伍军人听觉缺陷的特征:主成分分析方法。
目的:对于有听力障碍的脑损伤史的正常听力患者的循证评估方案,目前尚无共识。这项工作使用了一个大型测试组来确定解释有和没有头部损伤史的参与者之间最大差异的措施,确定措施之间的关系,并探索参与者之间的表现模式,目的是确定在未来研究中应该考虑的措施,为这一独特的患者群体制定临床评估方案。方法:对95名被试完成的22项自我报告、中央听觉加工和认知加工测量数据进行主成分分析。参与者包括有爆炸暴露史的退伍军人,有非爆炸轻度创伤性脑损伤(mTBI)史的退伍军人,以及没有脑损伤史的对照组。结果:几个中央听觉加工和自我报告测量解释了数据集的差异。然而,分析显示,行为听觉处理测试的表现不能预测自我报告的听觉和非听觉症状严重程度。聚类分析进一步揭示了具有爆炸暴露史或非爆炸mTBI的参与者在表现上的差异。结论:目前的研究结果强调需要一个全面的,个性化的方法来照顾那些有头部损伤史的病人。在当前分析中确定的措施应该在未来的研究中进行调查,旨在为这一患者群体制定听觉评估方案。补充资料:https://doi.org/10.23641/asha.32060232。

期刊介绍: Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
