This investigation was designed to systematically examine the acquisition, maintenance, and response generalization effects of Sound Production Treatment (SPT) delivered via telehealth in comparison to existing in-person outcomes for SPT.
A multiple-baseline design across behaviors and participants was used with two individuals with chronic apraxia of speech (AOS) and aphasia. Accuracy of target speech sounds in treated and untreated words within phrases served as the dependent variable.
Both participants demonstrated positive gains for treatment and generalization items. Participant 1 demonstrated gains for both sets of treatment items with the application of treatment, but production accuracy at 2 and 6 weeks posttreatment was inconsistent. Participant 2 demonstrated large gains for both sets of treatment items with good maintenance at 2 and 6 weeks posttreatment. Effect sizes for both participants were similar to the traditional (in-person) SPT effect size benchmarks.
The positive outcomes from this study indicate that individuals with AOS can benefit from SPT delivered via telehealth. These findings warrant further research examining the effects of SPT through telehealth and should include individuals with AOS with varying severity. This investigation serves as the first telehealth study to systematically examine treatment outcomes for SPT.
本研究旨在系统地考察通过远程医疗提供的语音产生治疗（SPT）的获得、维持和反应泛化效果，与现有的 SPT 面对面治疗结果进行比较。
采用跨行为和参与者的多项基线设计，对两名慢性言语失用症（AOS）和失语症患者进行研究。短语中治疗和未治疗单词中的目标语音的准确性作为因变量。
两名参与者在治疗和泛化项目上都表现出积极的收益。参与者 1 在应用治疗后，两组治疗项目都取得了收益，但治疗后 2 周和 6 周的发音准确性不一致。参与者 2 在两组治疗项目中都取得了较大的收益，并且在治疗后 2 周和 6 周的维持效果良好。两名参与者的效果大小与传统（面对面）SPT 效果大小基准相似。
这项研究的积极结果表明，AOS 患者可以从远程医疗提供的 SPT 中受益。这些发现需要进一步研究通过远程医疗进行 SPT 的效果，并应包括具有不同严重程度的 AOS 患者。本研究是第一个系统地考察 SPT 远程治疗结果的研究。
