Background The Rapid Syllable Transition (ReST) treatment is an effective intervention designed to address the planning and programming disorder found in childhood apraxia of speech. To date, no study has considered its use with children who speak languages other than English. Aim This pilot study aimed to examine the use of ReST treatment with Italian children. We hypothesized that the ReST approach would improve the overall accuracy of the targeted behaviors of lexical stress, smoothness, and phonemic accuracy, whereas phonemic and phonetic accuracy of untreated items would remain stable. Method Two monolingual Italian-speaking children with childhood apraxia of speech received therapy in 12 one-hour sessions, 2-3 times per week, using a single-case experimental design. The treatment procedures used in English were replicated in Italian with one change: In English, two stress patterns are treated. Italian commonly uses three stress patterns; therefore, the stimuli were modified accordingly. Accuracy of articulation, lexical stress, and smoothness were assessed at pretreatment and 1 day, 1 week, and 4 months posttreatment in treated and untreated pseudowords and in real words and sentences. Results Both children improved on treated pseudowords and real words with moderate effect sizes, but only one child generalized to untreated pseudowords. Maintenance of treatment results was observed in both participants. Articulation of control phonemes did not change. Conclusions ReST treatment in Italian is feasible, and a treatment effect was found, showing that its use may be valid in languages other than English. Further research is required.

对患有言语失用症的意大利儿童进行快速音节过渡治疗的单例试验性实验设计研究。

背景快速音节过渡（ReST）治疗是一种有效的干预措施，旨在解决儿童言语失用症中发现的计划和编程障碍。迄今为止，还没有研究考虑将其用于说英语以外的语言的孩子。目的这项初步研究旨在研究意大利儿童对ReST疗法的使用情况。我们假设，ReST方法将提高词汇重音，平滑度和音素准确性的目标行为的整体准确性，而未处理项目的音素和语音准确性将保持稳定。方法使用单例实验设计，两个12个小时的一小时课程，每周2-3次，接受了2种讲意大利语的小语种儿童语言失语的儿童接受的治疗。英语中使用的治疗程序以意大利语进行了复制，但有一个变化：英语中，处理了两种压力模式。意大利人通常使用三种压力模式：因此，刺激被相应地修改。在处理前和处理后的和未处理的伪词以及真实单词和句子中，评估了在预处理以及处理后1天，1周和4个月时的清晰度，词法重音和平滑度的准确性。结果这两个孩子在处理的伪单词和真实单词方面都有中等程度的效果改善，但是只有一个孩子推广到未处理的伪单词。两名参与者均观察到治疗结果的维持。控制音素的发音没有改变。结论用意大利语进行ReST治疗是可行的，并且具有治疗效果，表明其在英语以外的其他语言中的使用可能是有效的。需要进一步的研究。补充材料https://doi.org/10.1044/2021_AJSLP-20-00133。
