Abstract

Background: Persons with nonfluent aphasia (PWNA) use feedback from external agents (e.g., speech-language pathologists) and self-feedback to improve their language production. The extent to which PWNA can improve their language production using their self-feedback alone is underexplored. In a proof-of-concept study, we developed an automated recursive self-feedback procedure to demonstrate the extent to which two PWNA who used self-feedback alone improved their production of sentences from trained and untrained scripts. In the current study, we use the Rehabilitation Response Specification System as a framework to replicate our initial findings.

Method: We tested the effects of two treatments: script production with recursive self-feedback and script production with external feedback in four persons with chronic nonfluent aphasia. We compared the effects of treatment by measuring percent script produced, speaking rate, and speech initiation latency of trained and untrained scripts. The participants received the treatments remotely through mini tablets using two versions of a mobile app we developed. All the participants received each treatment intensively for 14 sessions across 2-3 weeks. We estimated clinical improvements of production of sentences from trained and untrained scripts through nonoverlap of all pairs analysis of performance pretreatment and posttreatment.

Results: Both treatments improved PWNA's language production. Recursive self-feedback improved speaking rate and speech initiation latency, which generalized to untrained scripts in all participants. External feedback treatment did not generalize to improvement in speaking rate in two participants.

Conclusions: Our findings confirm our initial evidence that PWNA can self-improve their sentence production from scripts through recursive self-feedback. This novel procedure enables PWNA to autonomously enhance their language production over time. Given the evidence and the mechanics of the procedure, we propose that its utility is not constrained by linguistic idiosyncrasies across cultures. Consequently, it has the potential to bypass linguistic barriers to aphasia care.

通过自动递归自我反馈提高非流利性失语症患者的语言能力

背景：非流利性失语症患者（PWNA）通过外部机构（如言语病理学家）的反馈和自我反馈来提高语言能力。目前还没有充分研究 PWNA 在多大程度上可以仅通过自我反馈来提高语言能力。在一项概念验证研究中，我们开发了一种自动递归自我反馈程序，以证明两名仅使用自我反馈的残疾人语言学家在多大程度上提高了他们用训练过和未训练过的脚本造句的能力。在目前的研究中，我们将康复反应规范系统作为一个框架，以复制我们的初步研究结果：我们在四名慢性非流利性失语症患者身上测试了两种治疗方法的效果：递归自我反馈的脚本制作和外部反馈的脚本制作。我们通过测量训练脚本和未训练脚本的脚本生成百分比、说话速度和说话启动潜伏期来比较治疗效果。参与者使用我们开发的两个版本的移动应用程序，通过迷你平板电脑远程接受治疗。所有参与者都在 2-3 周内集中接受了 14 次治疗。通过对治疗前和治疗后的表现进行非重叠分析，我们估算了训练过的和未训练过的脚本造句的临床改善情况：结果：两种治疗方法都改善了 PWNA 的语言表达能力。递归自我反馈提高了说话速度和说话启动潜伏期，这在所有参与者的未训练脚本中都得到了推广。外部反馈治疗并不能改善两名参与者的说话速度：我们的研究结果证实了我们的初步证据，即 PWNA 可以通过递归自我反馈来自我改善根据脚本造句的能力。这种新颖的程序使 PWNA 能够随着时间的推移自主提高语言能力。鉴于这些证据和该程序的机制，我们认为它的效用不受不同文化间语言特异性的限制。因此，它有可能绕过失语症护理的语言障碍。补充材料：https://doi.org/10.23641/asha.27007060。

期刊介绍： Mission: AJSLP publishes peer-reviewed research and other scholarly articles on all aspects of clinical practice in speech-language pathology. The journal is an international outlet for clinical research pertaining to screening, detection, diagnosis, management, and outcomes of communication and swallowing disorders across the lifespan as well as the etiologies and characteristics of these disorders. Because of its clinical orientation, the journal disseminates research findings applicable to diverse aspects of clinical practice in speech-language pathology. AJSLP 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 speech-language pathology, including aphasia; apraxia of speech and childhood apraxia of speech; aural rehabilitation; augmentative and alternative communication; cognitive impairment; craniofacial disorders; dysarthria; fluency disorders; language disorders in children; speech sound disorders; swallowing, dysphagia, and feeding disorders; and voice disorders.
