Outcomes of script training for individuals with apraxia of speech (AOS) and mild anomic aphasia were investigated. Script training is a functional treatment that has been successful for individuals with aphasia but has not been applied to individuals with AOS. Principles of motor learning were incorporated into training to promote long-term retention of scripts.
Three individuals with AOS completed script training. A multiple-baseline, across-behaviors design examined acquisition of client-selected scripts. Errors and speaking rates were also analyzed. Random practice and delayed feedback were incorporated into training to promote motor learning. Probes for long-term retention were elicited up to 6 months after treatment.
All clients successfully acquired their scripts, and probes demonstrated script retention 6 months after treatment. Errors generally decreased but remained variable even during maintenance and retention probes. Speaking rate increased for 2 clients but also remained variable.
Script training was successful and functional for clients with AOS. Clients reported increased confidence, speaking ease, and speech naturalness. Although scripts did not become errorless, clients retained their scripts and reported using them frequently. Whether principles of motor learning may have promoted the long-term retention of scripts exhibited by participants must be determined through future research.
研究脚本训练对言语失用症（AOS）和轻度命名性失语症患者的治疗效果。脚本训练是一种功能治疗方法，对失语症患者有效，但尚未应用于言语失用症患者。运动学习原则被纳入训练中，以促进脚本的长期保留。
3 名言语失用症患者接受了脚本训练。采用跨行为的多基线设计来检验患者对所选脚本的习得情况。同时分析错误和说话速度。随机练习和延迟反馈被纳入训练中以促进运动学习。在治疗后 6 个月进行长期保留测试。
所有患者都成功习得脚本，并且在治疗后 6 个月的测试中保留了脚本。错误通常减少，但即使在维持和保留测试期间，错误仍然存在且多变。2 名患者的说话速度有所提高，但仍存在变化。
脚本训练对言语失用症患者是成功且有效的。患者报告说，他们的信心、说话的轻松程度和言语自然度都有所提高。尽管脚本没有变得完全无错误，但患者保留了他们的脚本并报告经常使用。未来的研究需要确定运动学习原则是否促进了参与者展示的脚本的长期保留。
