快速音节转换疗法(Rest)和超声生物反馈是治疗儿童言语失用(CAS)的有效方法。该研究的目的是比较这两种基于运动的治疗方法对患有CAS的学龄儿童的疗效。在单点、单盲随机对照试验中，14名6-13岁的CAS儿童被随机分配到超声生物反馈治疗(具有言语运动链练习结构)或休息6周的12个疗程。在悉尼大学，治疗由经过认证的言语语言病理学家培训和监督的学生进行。两组受试者分别于治疗前、治疗后即刻、治疗后1个月比较两组未治疗的词和句子的语音准确率(音素正确率)和韵律严重程度(词汇重音错误和音节分离)。两组在治疗项目上均有显著改善，表明治疗效果。在任何时候，不同的组之间都没有区别。从实验前到实验后，两组受试者在未经处理的单词和句子上的语音准确度均有显着提高，而两组受试者在实验前的韵律测试中均未表现出明显改善。两组在1个月的随访中都保留了语音准确度的变化。据报道，在1个月的随访中，韵律准确性有了显著的改善。休息和超声生物反馈同样有效。对于患有CAS的学龄儿童，休息或超声生物反馈可能是可行的治疗选择。Https://doi.org/10.23641/asha.22114661
Both Rapid Syllable Transition Treatment (ReST) and ultrasound biofeedback are effective approaches to treating childhood apraxia of speech (CAS). The purpose of the study was to compare outcomes from these two motor-based treatment approaches for school-age children with CAS. In a single site, single blind randomized control trial, 14 children with CAS ages 6–13 years were randomly assigned to 12 sessions over 6 weeks of either of ultrasound biofeedback treatment (with a speech motor chaining practice structure) or ReST. Treatment was delivered at The University of Sydney by students trained and supervised by certified speech-language pathologists. Transcriptions from blinded assessors were used to compare the two groups on speech sound accuracy (percent phonemes correct) and prosodic severity (lexical stress errors and syllable segregation) in untreated words and sentences at three time points: pretreatment, immediately posttreatment, and 1-month posttreatment (i.e., retention). Both groups showed significant improvement on treated items indicating a treatment effect. At no time was there a difference between groups. Both groups showed a significant improvement in speech sound accuracy on untreated words and sentences from pre to post and neither group showed an improvement in prosody pre–post. Changes to speech sound accuracy were retained by both groups at 1-month follow-up. Significant improvement in prosodic accuracy was reported at the 1-month follow-up. ReST and ultrasound biofeedback were equally effective. Either ReST or ultrasound biofeedback may be viable treatment options for school-age children with CAS. https://doi.org/10.23641/asha.22114661
