ABSTRACT

Speech-language pathology caseloads often include individuals with hearing loss and a coexisting neurogenic communication disorder. However, specific treatment techniques and modifications designed to accommodate this population are understudied. Using a single-case experimental design, the current study investigated the utility of modified Video Implemented Script Training for Aphasia (VISTA) for an individual with nonfluent/agrammatic variant primary progressive aphasia and severe-to-profound, bilateral hearing loss. We analyzed the impact of this intervention, which incorporates orthographic input and rehearsal, on script production accuracy, speech intelligibility, grammatical complexity, mean length of utterance, and speech rate. Treatment resulted in comparable positive outcomes relative to a previous study evaluating script training in nonfluent/agrammatic primary progressive aphasia patients with functional hearing. Follow-up data obtained at three months, six months, and one year post-treatment confirmed maintenance of treatment effects for trained scripts. To our knowledge, this is the first study to investigate a modified speech-language intervention tailored to the needs of an individual with PPA and hearing loss, with findings confirming that simple treatment modifications may serve to broaden the range of treatment options available to those with concomitant sensory and communication impairments.

摘要

言语语言病理学案例通常包括患有听力损失和并存的神经源性交流障碍的个体。然而，旨在适应这一人群的特定治疗技术和修改尚未得到充分研究。本研究使用单案例实验设计，研究了针对患有非流利/语法变异的原发性进行性失语症和重度至重度双侧听力损失的个体，改进的失语症视频实施脚本训练 (VISTA) 的效用。我们分析了这种干预（包括正字法输入和排练）对脚本制作准确性、语音清晰度、语法复杂性、平均话语长度和语速的影响。相对于之前的一项评估具有功能性听力的非流利/语法不全的原发性进行性失语症患者的脚本训练的研究，治疗产生了可比的积极结果。在治疗后三个月、六个月和一年获得的后续数据证实了训练脚本的治疗效果得以维持。据我们所知，这是第一项针对 PPA 和听力损失患者的需求量身定制的改良言语语言干预研究，研究结果证实，简单的治疗修改可能有助于扩大那些患有 PPA 和听力损失的人可用的治疗选择范围伴随的感觉和沟通障碍。一年后治疗确认维持训练脚本的治疗效果。据我们所知，这是第一项针对 PPA 和听力损失患者的需求量身定制的改良言语语言干预研究，研究结果证实，简单的治疗修改可能有助于扩大那些患有 PPA 和听力损失的人可用的治疗选择范围伴随的感觉和沟通障碍。一年后治疗确认维持训练脚本的治疗效果。据我们所知，这是第一项针对 PPA 和听力损失患者的需求量身定制的改良言语语言干预研究，研究结果证实，简单的治疗修改可能有助于扩大那些患有 PPA 和听力损失的人可用的治疗选择范围伴随的感觉和沟通障碍。
