Abstract
PURPOSE There are multiple frameworks for goal writing that are applicable to the practice of speech-language pathology. Motor-based speech disorders are a subset of speech sound disorders that are thought to require specific elements of intervention that are typically not addressed in the traditional frameworks used in the clinical setting. The purpose of this tutorial is to review general approaches of goal writing and suggest additional elements that may be used to improve the efficiency and effectiveness of treatment for childhood motor speech disorders, specifically childhood apraxia of speech (CAS). METHOD Existing models of goal writing were reviewed to ascertain elements common to most of these models. A basic framework was chosen and modified to include behaviors, conditions, and approaches to goal measurement tailored to the clinical needs of children with CAS. A resource for clinical decision making for children with CAS was developed to inform goal writing at the onset of treatment and adaptations that occur over the course of treatment. Case studies are presented to demonstrate how the presented framework can be applied to writing goals for motor-based treatment for two different children with CAS. DISCUSSION Children with CAS require a specialized approach to intervention, which requires goals to reflect the unique clinical needs of this population. This tutorial offers resources that use the best available research evidence and current understanding of effective treatment practices for CAS to guide clinical decision making for motor-based intervention and goal writing. This tutorial is intended to guide treatment planning across varied settings to facilitate progress and optimize treatment outcomes for children with CAS.

Abstract
PURPOSE The purposes of this review article were to provide an introduction to and "bird's-eye" overview of the current evidence base for treatment of childhood apraxia of speech (CAS), identify some gaps and trends in this rapidly growing literature, and formulate some future research directions, in order to advance the evidence base and clinical practice for children with CAS. METHOD Following a brief introduction outlining important concepts, a narrative review of the CAS treatment literature is provided, and trends and future directions are identified based on this review. The review is organized around four fundamental treatment research questions: (a) "Does Treatment X work?", (b) "Does Treatment X work better than Treatment Y?", (c) "For whom does Treatment X work?", and (d) "What does 'work' mean, anyway?" RESULTS A wide range of CAS treatments with varying degrees of evidence for efficacy exists. Research is beginning to emerge that compares different treatments and seeks to determine optimal treatment parameters. Few studies to date have explored child-level predictors of treatment response, and the evidence base currently is limited in scope with respect to populations and outcomes studied. CONCLUSIONS A growing evidence base supports the efficacy of a number of treatments for CAS. However, many important gaps in the literature were identified that warrant redoubled and sustained research attention. Research is beginning to emerge that addresses treatment optimization, comparison, candidacy, and outcomes. Suggestions for future research are offered, and the concept of a hypothesized pathway was applied to CAS to illustrate how components of an intervention can effect change in a clinical goal and can help guide development and refinement of treatments for children with CAS.

Abstract
PURPOSE Childhood apraxia of speech (CAS) is a multivariate motor speech disorder that requires a motor-based intervention approach. There is limited treatment research on young children with CAS, reflecting a critical gap in the literature given that features of CAS are often in full expression early in development. Dynamic Temporal and Tactile Cueing (DTTC) is a treatment approach designed for children with severe CAS, yet the use of DTTC with children younger than 3 years of age has not been examined. METHOD A multiple single-case design was employed to examine the use of DTTC in seven children with CAS (aged 2.5-5 years) over the course of 6 weeks of intervention. Changes in word accuracy were measured in treated words from baseline to posttreatment and from baseline to maintenance (6 weeks posttreatment). Generalization of word accuracy changes to matched untreated words was also examined. A linear mixed-effects model was used to estimate the change in word accuracy for treated and untreated words across all children from baseline to posttreatment and to maintenance. A quasi-Poisson regression model was used to estimate mean change and calculate effect sizes for treated and untreated words. RESULTS Group-level analyses revealed significant changes in word accuracy for treated and untreated words at posttreatment and maintenance. At the child level, six of seven children displayed medium-to-large effect sizes where word accuracy increased in an average of 3.4/5 words across all children. Each child displayed some degree of generalization to untreated targets, specifically for words with the same syllable shape as the treated words. CONCLUSIONS These results demonstrate that DTTC can yield positive change in some young children with CAS. Key differences in each child's performance are highlighted.

Abstract
Motor Speech Disorders is an umbrella term for a set of separate dysfunctions of speech outcome associated with neurological disorders. Motor speech disorders (MSD) are classified as Speech Motor delay (SMD), Childhood dysarthria (CD), Childhood Apraxia of Speech (CAS), and Concurrent CD and CAS. The incidence and prevalence of MSD in population is uncertain. A research gap exists, making evidence-based practice questionable as regards intervention for MSD and is an area of research. Hence, current narrative review was conducted to review and highlight treatment of MSD since evidence-based treatment approach may benefit patient even years after a brain lesion. To achieve this objective literature search was conducted using search engines and data bases including google, google scholar, web of science & PubMed from 1998 to 2023 with keywords "motor speech disorder, dysarthria, apraxia, speech motor delay and combinations of these words with English language and no other limitations. Our search revealed 170 articles, news, publications of which 34 were used for review (Fig.1).

Abstract
PURPOSE Motor speech and augmentative and alternative communication (AAC) interventions are commonly used with children with cerebral palsy (CP) but there is limited literature comparing the effectiveness of these interventions. The purpose of this study was to investigate the effectiveness of intensive AAC, Rapid Syllable Transition Treatment (ReST), and blended intervention, a combination of motor-speech and AAC, on speech accuracy and sentence length and complexity. METHODS A single case experimental design across participants with repeated measurements across phases (ABACADA design) was used. Four participants aged 8-14 years with CP who used a speech-generating device (SGD) received three 6-week intervention blocks that included ReST, AAC, and blended intervention. Measures were taken during intervention and baseline phases and at maintenance two and four weeks after the last intervention phase. Participants were randomized to starting with either ReST or AAC with the blended intervention delivered last. RESULTS All participants improved their speech accuracy and sentence length and complexity in speech and with their SGD in all three interventions. The data demonstrated overall immediacy of the effect with all interventions and retention of gains across the whole sequence of phases. The order of AAC or ReST interventions or the severity of CP did not impact the intervention gains. CONCLUSION This study suggests that intensive AAC, a multi-modal approach, and ReST improve speech accuracy and sentence length and complexity in children with moderate CP, but all require further investigation.Implications for rehabilitationIn this paper intensive AAC intervention with a speech generating device (SGD), ReST treatment and multimodal blended intervention were effective in improving speech accuracy and sentence length and complexity in both verbal speech and on communication with the SGD.ReST treatment has not been used with children with CP before. This study established a proof of concept for its effectiveness in children with CP. Further research is warranted.

Abstract
Individuals with childhood apraxia of speech often exhibit greater difficulty with expressive language than with receptive language. As a result, they may benefit from alternative modes of communication. Here, we present a patient with childhood apraxia of speech who used pointing as a means of communication at age 2 ¼ years and self-made gestures at age 3½, when he had severe difficulties speaking in spite of probable normal comprehension abilities. His original gestures included not only word-level expressions, but also sentence-length ones. For example, when expressing "I am going to bed," he pointed his index finger at himself (meaning I ) and then put both his hands together near his ear ( sleep ). When trying to convey the meaning of "I enjoyed the meal and am leaving," he covered his mouth with his right hand ( delicious ), then joined both of his hands in front of himself ( finish ) and finally waved his hands ( goodbye ). These original gestures and pointing peaked at the age of 4 and then subsided and completely disappeared by the age of 7, when he was able to make himself understood to some extent with spoken words. The present case demonstrates an adaptive strategy for communication that might be an inherent competence for human beings.

Abstract
CTNNB1 syndrome is an autosomal-dominant neurodevelopmental disorder featuring developmental delay; intellectual disability; behavioral disturbances; movement disorders; visual defects; and subtle facial features caused by de novo loss-of-function variants in the CTNNB1 gene. Due to paucity of data, this study intends to describe feeding issues and oral-motor dyspraxia in an unselected cohort of 10 patients with a confirmed molecular diagnosis. Pathogenic variants along with key information regarding oral-motor features were collected. Sialorrhea was quantified using the Drooling Quotient 5. Feeding abilities were screened using the Italian version of the Montreal Children's Hospital Feeding Scale (I-MCH-FS). Mild-to-severe coordination difficulties in single or in a sequence of movements involving the endo-oral and peri-oral muscles were noticed across the entire cohort. Mild-to-profuse drooling was a commonly complained-about issue by 30% of parents. The mean total I-MCH-FS t-score equivalent was 43.1 ± 7.5. These findings contribute to the understanding of the CTNNB1 syndrome highlighting the oral motor phenotype, and correlating specific gene variants with clinical characteristics.

Abstract
PURPOSE Advancements in genetic testing and analysis have allowed improved identification of the genetic basis of childhood apraxia of speech, a rare speech presentation. This study aimed to understand speech-language pathologists' (SLPs') consideration of incorporation of genetics in clinical practice using a theory-informed qualitative approach. METHOD Semistructured interviews were conducted with 12 pediatric SLPs using a behavior change theory (Theoretical Domains Framework [TDF]) within a case study describing a child with complex co-occurring features, including childhood apraxia of speech. Interviews focused on three stages of the patient journey (prereferral, referral, and postreferral). Interviews were analyzed to identify barriers and enablers to considering incorporation of genetics in current clinical practice. Barriers and enablers were grouped and mapped onto a contextually relevant TDF-coded analysis framework. RESULTS Barriers were identified across several TDF domains, through all stages of the patient journey. Lack of confidence, relevance, and level of experience were most common prereferral, and connection to and awareness of genetics services and contextual factors were barriers in the referral stage. Perception of professional role, knowledge, and beliefs about effects on families were barriers postreferral. Associated enablers were also identified, including seeing value in genetic diagnosis, support from other health care professionals, supervision, and relationships with genetics services. CONCLUSIONS Results of this qualitative study highlight barriers and enablers to incorporating genetics into speech-language pathology clinical practice. These findings will assist in the development of theory-informed implementation strategies to support SLPs into the future. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.24112800.

Abstract
PURPOSE Speech-Music Therapy for Aphasia (SMTA), a method that combines speech therapy and music therapy, is introduced as a treatment method for childhood apraxia of speech (CAS). SMTA will be evaluated in a proof-of-principle study. The first case study is presented herein. METHOD SMTA was evaluated in a study with a single-subject experimental design comparing 10 weeks of treatment with 2 months of no treatment. The research protocol included a pretest, baseline phase, treatment phase, posttest, no-treatment phase, and follow-up test. The participant was a boy with CAS aged 5;8 (years;months). Outcome measures were selected to reflect both intelligibility in daily communication as well as features of CAS and speech motor planning and programming. RESULTS Results on the Intelligibility in Context Scale-Dutch (ICS-Dutch) and in the analysis of a spontaneous speech sample suggest generalization of treatment effects. Improvements were found in measures that reflect complex speech motor skills, that is, the production of consonant clusters and consistency. CONCLUSIONS This case study showed that speech production of the participant improved after treatment with SMTA. Although intelligibility as measured with the ICS-Dutch improved over the study period, objectifying changes at the level of intelligibility in daily communication proved to be difficult. Additional measures may be necessary to gain more insight into treatment effects at this level. Overall, the results of this first case study provide sufficient support and important leads for further evaluation of SMTA in the treatment of CAS in a proof-of-principle study.

Abstract
PURPOSE Much of the research literature on childhood apraxia of speech (CAS) has focused on understanding, diagnosing, and treating the impairment, rather than examining its functional effect on children's daily lives. This study focuses on the Personal Factors component of the World Health Organization International Classification of Functioning, Disability and Health-Children and Youth Version Framework. Specifically, the purpose was to examine the self-reported communication attitudes of children with CAS. METHOD Two validated communication attitude questionnaires were administered to 12 children with CAS enrolled in an intensive speech-focused intervention (age range: 4-10 years old). Children's scores were compared to the questionnaires' typically developing norms. Descriptive analyses explored relationships between communication attitude and CAS severity, caregiver perceptions of communicative participation, frustration ratings during therapy, and change in communication attitude over a brief time. RESULTS Older (ages 6-10 years) but not younger (ages 4-5;11 [years;months]) children with CAS were more likely to have negative attitudes about their speech. No clear relationships were observed between communication attitudes and caregiver perceptions of communicative participation; small positive relationships were observed between communication attitude and frustration during therapy. For the younger children, there was also a relationship with CAS severity. For most children, no change in communication attitude was observed over a brief period, though one child appeared to develop more negative and one appeared to develop more positive attitudes. CONCLUSIONS These initial findings suggest that older children with CAS may be at greater risk for negative communication attitudes than their peers without CAS. The findings also highlight the need to include more child self-report measures in research. Further implications for CAS assessment and intervention are discussed.

Abstract
PURPOSE The Multilevel word Accuracy Composite Scale (MACS) is a novel whole-word measure of speech production accuracy designed to evaluate behaviors commonly targeted in motor-based intervention for childhood apraxia of speech (CAS). The MACS yields a composite score generated through ratings of segmental accuracy, word structure maintenance, prosody, and movement transition. This study examined the validity of the MACS through comparison to established measures of speech accuracy. Reliability was also examined within and between practicing speech-language pathologists (SLPs). METHOD The MACS was used to rate 117 tokens produced by children with severe CAS. Ratings were performed in the laboratory setting by two expert raters and by practicing SLPs (N = 19). Concurrent validity was estimated through comparison of expert MACS ratings (i.e., MACS score and each component rating) to measures of speech accuracy (percent phoneme correct and the 3-point scale) using correlational analyses. Reliability was examined between expert raters and across SLP raters using the intraclass correlation coefficient to examine interrater reliability of expert ratings, in addition to inter- and intrarater reliability of SLP ratings. RESULTS Correlation analyses between MACS ratings (i.e., MACS score and component ratings) and existing measures of speech accuracy revealed small to large positive correlations between measures. Reliability analyses revealed moderate to excellent reliability for MACS ratings performed by expert raters and between (interrater) and within (intrarater) SLP raters. CONCLUSIONS Analyses of concurrent validity indicate that the MACS aligns with established measures, yet contributes novel elements for rating speech accuracy. Results further support the MACS as a reliable measure for rating speech accuracy in children with severe speech impairment for ratings performed by expert raters and practicing clinicians.

Abstract
PURPOSE The aim of this study was to pilot the efficacy of rapid syllable transition (ReST) treatment when provided once per week for a 50-min treatment session for 12 weeks with five children with childhood apraxia of speech. Of central importance was the children's retention and generalization of gains from treatment as indicators of speech motor learning. METHOD A multiple-baseline across-participant design was employed to investigate (a) treatment effect on the 20 treated pseudowords, (b) generalization to 40 untreated real words and 10 untreated polysyllabic word sentences, and (c) maintenance of any treatment and generalization goals to up to 4 months posttreatment. To investigate any difference between in-session performance and retention, a comparison was made between data collected during treatment and probe sessions. RESULTS Treatment data collected during therapy showed all children improving across their 12 treatment sessions. Three of the five children showed a treatment effect on treated pseudowords in the probe sessions, but only one child showed generalization to untreated real words, and no children showed generalization to sentences. CONCLUSIONS ReST treatment delivered at a dose frequency of once per week was efficacious for only one of the five children. In-session treatment data were not a reliable indicator of children's learning. One session per week of ReST therapy is therefore not recommended.

Abstract
PURPOSE The aim of this study was to describe changes in speech intelligibility and interrater and intrarater reliability of naive listeners' ratings of words produced by young children diagnosed with childhood apraxia of speech (CAS) over a period of motor-based intervention (dynamic temporal and tactile cueing [DTTC]). METHOD A total of 120 naive listeners (i.e., listeners without experience listening to children with speech and/or language impairments; age range: 18-45 years) orthographically transcribed single-word productions by five children (age range: 2;6-3;11 [years;months]) across three time points over an intervention period (baseline, post-treatment, maintenance). Changes in intelligibility and interrater and intrarater reliability were examined within and across time points. RESULTS Speech intelligibility significantly increased in children with CAS over the course of treatment, and these gains were also maintained at 6 weeks posttreatment. There was poor-to-fair consistency between listeners (interrater reliability) and excellent consistency within listeners (intrarater reliability) in ratings of speech intelligibility within and across time points. CONCLUSIONS Motor-based intervention increases speech intelligibility following a period of DTTC treatment. Variability among naive listeners of speech intelligibility was also present, with intrarater reliability (within listeners) yielding greater consistency than interrater reliability (between listeners). The implications for including naive listeners as raters of speech intelligibility for research and clinical purposes are discussed.

Abstract
PURPOSE Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of speech (CAS). Furthermore, the degree to which individual patterns of baseline probe word accuracy, receptive language, and cognition predicted response to treatment was explored. METHOD Probe data were collected from seven children with CAS (aged 2;5-5;0 [years;months]) who received 6 weeks of Dynamic Temporal and Tactile Cueing (DTTC) treatment. Using a multidimensional approach to measuring speech performance, auditory-perceptual (whole-word accuracy), acoustic (whole-word duration), and kinematic (jaw movement variability) analyses were conducted on probe words produced pre- and posttreatment. Standardized tests of receptive language and cognition were administered pretreatment. RESULTS There was a negative relationship between auditory-perceptual measures of word accuracy and movement variability. Higher word accuracy was associated with lower jaw movement variability following intervention. There was a strong relationship between word accuracy and word duration at baseline, which became less robust posttreatment. Furthermore, baseline word accuracy was the only child-specific factor to predict response to DTTC treatment. CONCLUSIONS Following a period of motor-based intervention, children with CAS appeared to refine speech motor control in conjunction with improvements in word accuracy. Those who demonstrated the poorest performance at treatment onset displayed the greatest degree of gains. Taken together, these results reflect a system-wide change following motor-based intervention.

Abstract
BACKGROUND Childhood apraxia of speech (CAS) is a pediatric motor-based speech sound disorder that requires a specialized approach to intervention. The extant literature on the treatment of CAS commonly recommends intensive treatment using a motor-based approach, with some of the best evidence supporting the use of Dynamic Temporal and Tactile Cueing (DTTC). To date, a rigorous and systematic comparison of high and low dose frequency (i.e., frequency of therapy sessions) has not been undertaken for DTTC, resulting in a lack of evidence to guide decisions about the optimal treatment schedule for this intervention. The current study aims to fill this gap in knowledge by comparing treatment outcomes when dose frequency is varied. METHODS A randomized controlled trial will be conducted to examine the efficacy of low versus high dose frequency on DTTC treatment outcomes in children with CAS. A target of 60 children, 2;6-7;11 years of age, will be recruited to participate in this study. Treatment will be provided in the community setting by speech-language pathologists who have completed specialized training administering DTTC in a research reliable manner. True randomization with concealed allocation will be used to assign children to either the low or high dose frequency group. Treatment will be administered in 1-h sessions either 4 times per week over a 6-week period (high dose) or 2 times per week over a 12-week period (low dose). To measure treatment gains, probe data will be collected before treatment, during treatment, and 1 day, 1 week, 4 weeks, and 12 weeks post-treatment. Probe data will consist of customized treated words and a standard set of untreated words to assess generalization of treatment gains. The primary outcome variable will be whole word accuracy, encompassing segmental, phonotactic, and suprasegmental accuracy. DISCUSSION This will be the first randomized controlled trial to evaluate dose frequency for DTTC treatment in children with CAS.

Abstract
PURPOSE 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. METHOD 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). RESULTS 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. CONCLUSIONS ReST and ultrasound biofeedback were equally effective. Either ReST or ultrasound biofeedback may be viable treatment options for school-age children with CAS.

Abstract
PURPOSE Dysarthria is common among children with cerebral palsy (CP) and results in poor speech intelligibility and subsequently low communicative participation. Neuroplasticity evidence suggests that adherence to principles of motor learning (PML) improves motor speech intervention outcomes. Motor speech interventions aim to improve speech intelligibility and ultimately facilitate participation, but the effectiveness of these interventions and their inclusion of PML are not clear. Aims are as follows: (a) evaluate the effectiveness motor speech interventions in improving speech intelligibility; (b) summarize the aims, outcome measures, and outcomes relating to the International Classification of Functioning and Disability Child and Youth; and (c) summarize the principles of motor learning used in the intervention. METHOD Eight databases were searched, complemented by a hand search. Studies of any level of evidence were included if they used a motor speech intervention and measured speech in children with CP aged 0-18 years. Studies before 2000 or not in English were excluded. The review was conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study quality was rated using the Single Case Experimental Design Scale and Physiotherapy Evidence Database-P rating scales. The strength of evidence was evaluated with Grading of Recommendations, Assessment, Development and Evaluation. RESULTS Of 1,036 initial articles, 21 were included. Eight interventions were identified including 131 participants aged 3-18 years. All studies aimed to improve speech intelligibility or articulation and reported improvement at sound, word, or sentence level. One study reported improvements in communicative participation. The strength of evidence ranged from very low to moderate for one intervention. Adherence to PML was inconsistent. CONCLUSIONS The quality of evidence is very low to moderate. More research on motor speech interventions that adhere to PML is required. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.21817959.

Abstract
PURPOSE This is a pilot study to apply an articulatory kinematic speech intervention that uses the principles of motor learning (PML) to improve speech and resonance outcomes for children with cleft palate. It is hypothesized that (a) treatment that applies select PML during practice will improve production of treated phonemes, representing both active and inconsistent passive errors, at word level in children with cleft palate; (b) effects of practice on phonemes with active or inconsistent passive errors will generalize to untreated exemplars of treated phonemes; and (c) learning will be retained for at least 1-month posttreatment. METHOD A multiple-baseline design across participants combined with a crossover single-case experimental model was used. Participants attended two 8-week blocks of twice-weekly face-to-face speech therapy (40-50 min/treatment) to treat active and inconsistent passive cleft speech errors using articulatory kinematic speech intervention that applied PML. The participants were four children with cleft-type speech errors. The primary dependent variable measured was percentage of words correct across treatment items, generalization items, and control items. Perceptual accuracy of target words was scored. Effect sizes were calculated to quantify the magnitude of treatment effect. RESULTS For three children with active and inconsistent passive cleft speech errors and one child with active cleft speech errors and developmental phonological speech errors, this approach resulted in improvements to their treated items and generalization to their untreated items. Inconsistent passive cleft speech errors were particularly responsive to the treatment in the three children who presented with these errors. CONCLUSION This Phase I study has shown that articulatory kinematic speech intervention that applies the PML is effective in improving the speech outcomes for children with cleft palate and that there is validity in pursuing further research into this approach.

Abstract
Childhood apraxia of speech (CAS) is a subtype of motor speech disorder usually co-occurring with language impairment. A supramodal processing difficulty, involving executive functions (EFs), might contribute to the cognitive endophenotypes and behavioral manifestations. The present study aimed to profile the EFs in CAS, investigating the relationship between EFs, speech and language severity, and the connectivity of the frontal aslant tract (FAT), a white matter tract involved in both speech and EFs. A total of 30 preschool children with CAS underwent speech, language, and EF assessments and brain MRIs. Their FAT connectivity metrics were compared to those of 30 children without other neurodevelopmental disorders (NoNDs), who also underwent brain MRIs. Alterations in some basic EF components were found. Inhibition and working memory correlated with speech and language severity. Compared to NoND children, a weak, significant reduction in fractional anisotropy (FA) in the left presupplementary motor area (preSMA) FAT component was found. Only speech severity correlated and predicted FA values along with the FAT in both of its components, and visual-spatial working memory moderated the relationship between speech severity and FA in the left SMA. Our study supports the conceptualization of a composite and complex picture of CAS, not limited to the speech core deficit, but also involving high-order cognitive skills.

Abstract
PURPOSE Manual sign is a common alternative mode of communication taught to children with childhood apraxia of speech (CAS). Gesture use is positively related to later increases in vocabulary and syntactic complexity in typical development, but there is little evidence supporting the use of manual sign for children with CAS. We sought to identify the communicative functions of signs and gestures produced by children with CAS and to identify concurrent factors suggesting which children are more likely to benefit from sign-supported speech intervention. METHOD Measures of receptive and expressive language were gathered from 19 children (ages 3.8-11.1 years) with CAS in a school-based sign-supported speech program. Fourteen of the children produced a total of 145 manual signs, which included both gestures and signs from American Sign Language (M = 10.4 per child, SD = 11.6). Manual signs were coded according to whether they conveyed information that was semantically redundant with (complemented) or added information to (supplemented) their speech. RESULTS Children produced 107 complementary manual signs (75.4%) and 38 supplemental (24.6%) manual signs. Of the 38 supplemental signs, 24 (63.2%) provided additional information in the presence of unintelligible or no speech and 14 (36.8%) provided additional information in the presence of intelligible speech. Children's expressive language scores significantly predicted and accounted for 38.4% of the variance in the number of supplemental signs that children used. CONCLUSION Children with CAS whose oral expressive language was relatively more impaired produced the most supplementary signs, suggesting that children with oral expressive language challenges are more likely to rely on them for communicating words they cannot yet speak.

Abstract
PURPOSE The purpose of this study is to identify predictors of treatment outcomes in Rapid Syllable Transition Treatment (ReST) for childhood apraxia of speech through an individual participant data meta-analysis. METHOD A systematic literature search identified nine ReST studies for inclusion. Individual participant data were obtained, and studies were coded for methodological design, baseline participant characteristics, service delivery factors, and treatment outcomes. Bivariate analyses were conducted to identify potential predictor variables. Multiple linear regressions were then performed to identify predictors of treatment outcomes. RESULTS Data for 36 participants from seven studies were included in the statistical analyses. In multivariate modeling, better performance on treated pseudowords posttreatment was predicted by higher baseline expressive language and Goldman-Fristoe Test of Articulation scores, lower speech inconsistency and percentage of vowels correct, and higher pretreatment accuracy on pseudoword targets. Better performance on untreated real words posttreatment was predicted by higher pretreatment accuracy on real words. Gains in performance and retention of gains were not significantly predicted by any individual variable or combination of variables. CONCLUSIONS Baseline speech and expressive language skills and accuracy on pseudowords and real words were significant predictors of absolute posttreatment performance. Regardless of baseline characteristics, all children were statistically as likely to achieve gains during ReST and retain these gains for up to 4 weeks posttreatment. Large-scale prospective research is required to further examine the effects of dose frequency and co-occurring language impairments on treatment outcomes and the complex co-effects of percentage of vowels correct with other potential predictors.

Abstract
PURPOSE Treatment for children with autism spectrum disorder (ASD) and low verbal ability is a largely neglected area of study. Existing research focuses on language abilities; however, a subset of children with ASD also has speech sound disorders (SSDs). The purpose of this tutorial is to provide clinicians with evidence-based recommendations to guide speech assessment and treatment among children with ASD, low verbal ability, and suspected childhood apraxia of speech (CAS). METHOD Multifaceted search procedures were used to identify studies that have assessed or treated speech sound production among children with ASD. A narrative review and synthesis of the literature is followed by practical clinical recommendations based on best available evidence. CONCLUSIONS It is critically important to consider all possible hindrances to the development of functional communication ability for children with ASD. Speech sound production has been identified as a key predictor of expressive language outcomes, yet there are very few studies that address assessment and treatment of SSDs among children with ASD. Less is known about the presentation of CAS among children with ASD and low verbal ability. More research is needed to determine whether existing speech assessment and treatment methods are appropriate for children with ASD, if modifications are needed, or if new methods should be designed.

Abstract
Purpose This study sought to determine if children with childhood apraxia of speech (CAS) plus another major diagnosis (CAS+) are equivalent in communication and motor profiles to those with a primary diagnosis of CAS and no indication or report of any other diagnosis (CAS-Primary). Method This retrospective case-control study included a chart review of 143 children who were suspected of having CAS at Children's Hospital-Wisconsin between 1998 and 2004. Participants were between 30 and 127 months old and included 107 males. Participants were assigned to the suspected CAS-Primary group (n = 114) if they had characteristics of CAS but no other major diagnosis (e.g., galactosemia) and to the CAS+ group (n = 29) if a comorbid diagnosis was present. Groups were compared across demographic, communication, and motor characteristics. Results Children with CAS+ evidenced more severe motor profiles than those with CAS-Primary, χ2 = (1, n = 122) = 4.952, p = .026, and a small-to-medium effect size (Φ = .201). On average, communication profiles also tended to be more severe among those with CAS+ wherein receptive language was poorer and phonemic inventories were smaller than those with CAS-Primary. Conclusions These retrospective data suggest that comorbid diagnosis may play an important role in communication and motor development in children with suspected CAS. These exploratory findings should motivate future prospective studies that consider the role of concomitant diagnoses in symptom profile and response to treatment in children with CAS.

Abstract
Purpose: This study investigated the efficacy of Treatment for Establishing Motor Program Organization (TEMPOSM) in childhood apraxia of speech (CAS).Method: A mixed between- and within-participant design with multiple baselines across participants and behaviors was used to examine acquisition, generalization, and maintenance of skills. TEMPOSM was administered in four one-hour sessions a week over a four-week period for eleven participants (ages 5 to 8), allocated to either an immediate treatment group or a wait-list control group. Acoustic and perceptual variables were measured at baseline, immediate post-treatment, and one-month post-treatment.Results: Children demonstrated significant improvements in specific acoustic measures of segmentation and lexical stress, as well as perceptual measures of fluency, lexical stress, and speech-sound accuracy. Treatment and generalization effects were maintained one-month post-treatment with generalization to untreated stimuli.Conclusion: TEMPOSM was efficacious in improving segmental and suprasegmental impairments in the speech of children with CAS.

Abstract
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.

Abstract
Purpose A subset of children with autism spectrum disorder (ASD) has speech sound disorders, including childhood apraxia of speech (CAS). To date, virtually all speech treatment studies consider ASD an exclusionary criterion, resulting in little scientific evidence for treatment of CAS for children who also have ASD. This study proposes and tests a novel approach, Autism-Centered Therapy for Childhood Apraxia of Speech (ACT4CAS), as a theoretically and clinically informed speech treatment option for this population. Method Using a multiple-baseline design within and across participants, three children with co-occurring ASD and CAS received 11-18 treatment sessions. Treatment targets were individually designed and matched with untreated control words. Probes were administered at the start of each session to assess speech production accuracy perceptually. Changes in production accuracy were examined through visual inspection and quantified with effect sizes. Results Findings were mixed, with one child showing significant gains for half of the treated targets at follow-up and two children showing no clear improvement. Conclusions Preliminary evidence suggests potentially positive treatment effects for ACT4CAS when implemented as intended, although treatment intensity and disorder severity likely influence treatment outcome. Replication and comparison of ACT4CAS to other speech treatments is needed. Supplemental Material https://doi.org/10.23641/asha.14110445.

Abstract
Purpose This case-control study sought to determine if (a) children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development would perform differently on a procedural learning assessment and (b) whether grammatical ability would impact group differences. Method Communication, motor, and procedural learning abilities were assessed in 48 children with CAS (n = 13), SSD (n = 20), and typical development (n = 15), between 43 and 97 months of age (M = 66 months, SD = 12 months). Results On average, children with CAS demonstrated grammatical and motor impairments and required an increased number of exposures to the visuospatial sequence to demonstrate procedural learning, compared to peers with SSD or typical development. A subset of children from each group demonstrated an unanticipated procedural learning pattern wherein they evidenced an uptick in reaction time during the second sequenced block. Children with CAS with this pattern still evidenced procedural learning gains by the fifth sequenced block. In contrast, children with SSD and typical development with this pattern showed poor procedural learning outcomes and were characterized by lower scores on language and motor assessments as well. Conclusions This research provides partial support for the procedural learning deficit hypothesis in children with CAS and for a subset of children with SSD as well. Future research should examine the role of a serial reaction time task in identifying children at risk of multisystem communication and motor deficits.

Abstract
Digital games can make speech therapy exercises more enjoyable for children and increase their motivation during therapy. However, many such games developed to date have not been designed for long-term use. To address this issue, we developed Apraxia World, a speech therapy game specifically intended to be played over extended periods. In this study, we examined pronunciation improvements, child engagement over time, and caregiver and automated pronunciation evaluation accuracy while using our game over a multi-month period. Ten children played Apraxia World at home during two counterbalanced 4-week treatment blocks separated by a 2-week break. In one treatment phase, children received pronunciation feedback from caregivers and in the other treatment phase, utterances were evaluated with an automated framework built into the game. We found that children made therapeutically significant speech improvements while using Apraxia World, and that the game successfully increased engagement during speech therapy practice. Additionally, in offline mispronunciation detection tests, our automated pronunciation evaluation framework outperformed a traditional method based on goodness of pronunciation scoring. Our results suggest that this type of speech therapy game is a valid complement to traditional home practice.

Abstract
Introduction The current work presents a framework of motoric complexity where stimuli differ according to movement elements across a sound sequence (i.e., consonant transitions and vowel direction). This framework was then examined in children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development (TD). Method Twenty-four children (CAS, n = 8; SSD, n = 8; TD, n = 8), 5-6 years of age, participated in this study. The children produced words that varied in motoric complexity while transcription, acoustic, and kinematic data were collected. Multidimensional analyses were conducted to examine speech production accuracy, speech motor variability, and temporal control. Results Analyses revealed poorer accuracy, longer movement duration, and greater speech motor variability in children with CAS than TD (across all measures) and other SSDs (accuracy and variability). All children demonstrated greater speech motor variability and longer duration as movement demands increased within the framework of motoric complexity. Diagnostic grouping did not mediate performance on this task. Conclusions Results of this study are believed to reveal gradations of complexity with increasing movement demands, thereby supporting the proposed framework of motoric complexity. This work also supports the importance of considering motoric properties of sound sequences when evaluating speech production skills and designing experimental and treatment stimuli.

Abstract
Purpose: The aim was to investigate, describe and analyse speech characteristics, intelligibility, orofacial function and co-existing neurodevelopmental symptoms in children with SSD of unknown origin, persisting after six years of age.Method: The study included 61 children with SSD (6-17 years) of unknown origin, referred for a speech and oral motor examination. The severity of SSD was estimated using Percentage Consonants Correct (PCC) and Percentage Vowels Correct (PVC) and assessments of resonance based on Swedish Articulation and Nasality Test (SVANTE). Orofacial function was screened using the Nordic Orofacial Test-Screening (NOT-S). Parents completed the Intelligibility in Context Scale (ICS) and a questionnaire including questions about heredity, medical and neurodevelopmental conditions, and speech development.Result: SSD varied according to PCC (8-95%) and PVC (55-100%) measurements. Percentages of co-occurring disorders included: 51% resonance deviations, 90% intelligibility issues, and 87% orofacial difficulties. The most affected orofacial domains were "Chewing and swallowing" (41%), "Masticatory muscles and jaw function" (38%) and "Sensory function" (38%). The majority (64%) had co-existing dysfunctions relating to general motor and neurodevelopmental disorders.Conclusion: Children with persistent SSD are at risk for orofacial dysfunction, general motor difficulties and other neurodevelopmental disorders and therefore should be screened for co-occurring disorders.

JOURNAL OF COMMUNICATION DISORDERS 2020; 87:106026.

Abstract
PURPOSE One of the key principles of motor learning supports using knowledge of results feedback (KR, i.e., whether a response was correct / incorrect only) during high intensity motor practice, rather than knowledge of performance (KP, i.e., whether and how a response was correct/incorrect). In the future, mobile technology equipped with automatic speech recognition (ASR) could provide KR feedback, enabling this practice to move outside the clinic, supplementing speech pathology sessions and reducing burden on already stretched speech-language pathology resources. Here, we employ a randomized controlled trial design to test the impact of KR vs KP feedback on children's response to the Nuffield Dyspraxia Programme 3, delivered through an android tablet. At the time of testing, ASR was not feasible and so correctness of responses was decided by the treating clinician. METHOD Fourteen children with CAS, aged 4-10 years, participated in a parallel group design, matched for age and severity of CAS. Both groups attended a university clinic for 1-hr therapy sessions 4 days a week for 3 weeks. One group received high frequency feedback comprised of both KR and KP, in the style of traditional, face-to-face intensive intervention on all days. The other group received high frequency KR + KP feedback on 1 day per week and high frequency KR feedback on the other 3 days per week, simulating the service delivery model of one clinic session per week supported by tablet-based home practice. RESULTS Both groups had significantly improved speech outcomes at 4-months post-treatment. Post-hoc comparisons suggested that only the KP group showed a significant change from pre- to immediately post-treatment but the group difference had dissipated by 1-month post-treatment. Heterogeneity in response to intervention within the groups suggests that other factors, not measured here, may be having a substantive influence on response to intervention and feedback type. CONCLUSION Mobile technology has the potential to increase motivation and engagement with therapy and to mitigate barriers associated with distance and access to speech pathology services. Further research is needed to explore the influence of type and frequency of feedback on motor learning, optimal timing for transitioning from KP to KR feedback, and how these parameters interact with task, child and context-related factors.

Abstract
Purpose
The study of speech motor control has led to great advancements in the current understanding of childhood apraxia of speech (CAS). There remains a significant need to bridge the gap between theory and practice to fully understand the clinical implications of past research.
Method
This review article reviews the speech motor control research in CAS and discusses how these works have offered key information about the underlying motor deficits (Grigos et al., 2015; Terband et al., 2019), the influence of structured practice on speech performance (Case & Grigos, 2016; Grigos & Case, 2018), and the role of task complexity (Case, 2019; Case & Grigos, 2016; Grigos & Case, 2018). We highlight salient points from this existing literature and clinical implications to the assessment and treatment of CAS.
Conclusion
The study of speech motor control has shed light on a number of key factors related to CAS. Even within perceptually accurate speech, children with CAS display differences in movement patterning and timing control. Assessment must aim to more directly tax speech motor skills to obtain a thorough and accurate illustration of production deficits. Intervention is challenged with the task of not only improving production accuracy but also facilitating more efficient motor planning and programming. Motor-based intervention that applies motor learning principles and introduces variability across motor, phonetic, and prosodic contexts is believed to achieve this goal, though research is needed to better understand changes in speech motor control with treatment.

Abstract
Purpose
Childhood apraxia of speech (CAS) is a speech disorder that many generalist speech-language pathologists feel underqualified to treat. For children with CAS, this may result in ad hoc interventions resulting in slower progress. Research evidence for various CAS treatments is primarily limited to single-case experimental design studies; however, two treatments (Rapid Syllable Transition Treatment [ReST] and the Nuffield Dyspraxia Programme, Third Edition) have been compared in a single randomized controlled trial.
Conclusion
This tutorial describes one of those treatments: ReST which was designed to address the three consensus core features of CAS simultaneously: consistency and accuracy of sounds, sequencing, and prosody. The treatment uses nonwords to help children build and store accurate motor plans and programs using principles of motor learning. Treatment data are described, and commonly reported clinical issues are discussed. Recommendations for which children may be suitable for ReST and for evidence-based practice are described.

Abstract
Purpose The purpose of this article is to describe a treatment approach, Dynamic Temporal and Tactile Cueing (DTTC), and to provide clinicians and clinical researchers a clear understanding of the theory and principles that contributed to the design of the treatment as well as the clinical decisions that must be made when implementing it. While brief descriptions of DTTC have been provided in textbooks, a complete summary of the rationale, essential elements, method, and procedures has not yet been published. Such a summary is important so that clinicians can gain a better understanding of and more confidence in using the method for appropriate children. Furthermore, this article provides clinicians and clinical researchers essential information for measurement of fidelity. Method The important elements of the DTTC method with rationale for their inclusion are described. The temporal hierarchy of DTTC is depicted, and the dynamic procedure is described in detail, with suggestions for fidelity measurement. Finally, a discussion of important decisions clinicians must make when implementing DTTC is presented. Conclusions The goal of DTTC is to improve the efficiency of neural processing for the development and refinement of sensorimotor planning and programming. The rationale for DTTC in general, as well as the key elements important to its administration, are supported by models of speech production and theories of motor learning. Important clinical decisions regarding stimuli, organization of practice, and feedback are based on principles of motor learning in order to facilitate acquisition, retention, and continued improvement of motor speech skills.

Dual-task performance of speech and motor skill: verb generation facilitates grasping behaviour. Exp Brain Res 2020; 238:453-463.

Abstract
Pronouncing nouns or verbs while grasping distinctly alters movement. Changes in hand speed and final position occur according to the meaning of the words spoken. These results are typically found when executing a single movement paired with a single word. For example, pronouncing the word 'fast' increased the speed of the hand when reaching to grasp. Our objective was to compare how verb and noun fluency tasks interact with grasping behaviour in a grasp-to-construct task. Because previous imaging research shows that verb and noun production activates distinct neural areas, we reasoned that grasping outcomes would differ according to the category of word produced by participants. Specifically, we hypothesized that verb pronunciation would distinctly affect grasping behaviour compared to producing nouns. We recruited 38 young adults who performed a grasp-to-construct task and two different verbal fluency tasks. Participants completed each task (grasp, verb fluency, and noun fluency) separately as control conditions, and the grasping and each speaking task simultaneously for dual-task conditions. We found that during the dual-task condition, when generating nouns and grasping, participants made significantly more grasping errors (inaccurate grasps) compared to the control and verb dual-task conditions. Moreover, our results revealed a relationship between the number of verbs generated and grasping performance. Participants who generated more verbs were faster and more accurate during the motor component of the dual-task condition. This relationship was not observed when nouns were produced, indicating a unique relationship between verb production and functional grasping. The result is a facilitation effect, diminishing the negative outcome on motor control associated with increased cognitive load (as observed during noun pronunciation).

Abstract
Purpose The aim of this study was to test the hypothesis that children with inconsistent speech errors would respond differentially to 1 of 3 specific interventions depending on their primary underlying impairment: Children with deficient motor planning were expected to respond best to an auditory-motor integration (AMI) intervention, and children with deficient phonological planning were expected to respond best to a phonological memory and planning (PMP) intervention. Method Twelve participants were diagnosed with a motor planning (n = 7) or phonological planning (n = 5) deficit based on a comprehensive assessment, which included the Syllable Repetition Task as an important source of diagnostic evidence. An N-of-1 randomized controlled trial was used. Each child experienced all 3 interventions: AMI, PMP, and control (CTL); however, these interventions were randomly allocated to sessions within weeks (3 sessions per week × 6 weeks for 18 sessions). The AMI intervention procedures targeted knowledge of the acoustic-phonetic target and integration of auditory and somatosensory feedback during speech practice. The PMP intervention procedures targeted segmenting and recompiling the phonological plan for each word. The CTL intervention was standard drill practice. The child was taught 5 pseudowords in a meaningful context in each intervention condition. Results Same-day (SD) probes assessed transfer from taught pseudowords to untaught real words, and next-day (ND) probes assessed retention of that learning. Nonparametric resampling tests with pooling of p values across children with the same diagnosis were used to assess the results. Pooled p values indicated a significant benefit of AMI over PMP for the group with a motor planning deficit (p = 2.01E-04 for SD probes and 2.97E-03 for ND probes) and a significant benefit of PMP over AMI for the group with a phonological planning deficit (p = 1.22E-02 for SD probes and 1.32E-02 for ND probes). Response to the CTL intervention was variable within groups. Conclusion In this study, the child's underlying psycholinguistic deficit helped to predict response to intervention.

Abstract
Purpose The aim of this study was to examine 2 aspects of treatment intensity in treatment for childhood apraxia of speech (CAS): practice amount and practice distribution. Method Using an alternating-treatments single-subject design with multiple baselines, we compared high versus low amount of practice, and massed versus distributed practice, in 6 children with CAS. Conditions were manipulated in the context of integral stimulation treatment. Changes in perceptual accuracy, scored by blinded analysts, were quantified with effect sizes. Results Four children showed an advantage for high amount of practice, 1 showed an opposite effect, and 1 showed no condition difference. For distribution, 4 children showed a clear advantage for massed over distributed practice post treatment; 1 showed an opposite pattern, and 1 showed no clear difference. Follow-up revealed a similar pattern. All children demonstrated treatment effects (larger gains for treated than untreated items). Conclusions High practice amount and massed practice were associated with more robust speech motor learning in most children with CAS, compared to low amount and distributed practice, respectively. Variation in effects across children warrants further research to determine factors that predict optimal treatment conditions. Finally, this study adds to the evidence base supporting the efficacy of integral stimulation treatment for CAS. Supplemental Material https://doi.org/10.23641/asha.9630599.

Glob Pediatr Health 2019; 6:2333794X19851417. [PMID: 31223632 PMCID: PMC6566466 DOI: 10.1177/2333794x19851417] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Revised: 04/16/2019] [Accepted: 04/16/2019] [Indexed: 11/16/2022] Open
Abstract
Objective. This investigation researched the effectiveness of the PROMPT (Prompts for Restructuring Oral Muscular Phonetic Targets) method to address compensatory articulation errors in children with cleft palate. Design. Single-subject AB multiple baselines across participants and behaviors. Setting. Pediatric outpatient rehabilitation department in a local hospital in a metropolitan city. Participants. The investigation consisted of 3 participants (ages = 4:4 to 12:8) born with bilateral complete cleft lip and palate. All participants underwent several reconstructive surgeries to repair their lips and palates. Interventions. The PROMPT treatment was provided for 45 minutes 3 times a week for 4 weeks (3 weeks for Participant 2). Main Outcome Measure. Therapy sessions addressed anterior lingual speech motor phonemes across 3 tiers (syllables, words, and phrases). Results. Direct visual observation of data obtained throughout this investigation indicate potential positive effects and significant correlation between improvements in sound production at 3 tiers and the implementation of the PROMPT technique. Speech intelligibility was judged by 3 blinded listeners who were unfamiliar with children with speech disorders or with cleft palate speech. All listeners identified and judged improvement in overall speech intelligibility over the course of this investigation. Listeners examined speech samples selected from sessions 3, 6, 9, and 12. Conclusion. The findings in this investigation provide a potential relationship on the effectiveness of the PROMPT method and attainment of accurate speech productions in children with cleft palate producing compensatory articulation errors, resulting in improvement in overall speech intelligibility.

Abstract
Estimates of the prevalence of speech and motor speech disorders in persons with complex neurodevelopmental disorders (CND) can inform research in the biobehavioural origins and treatment of CND. The goal of this research was to use measures and analytics in a diagnostic classification system to estimate the prevalence of speech and motor speech disorders in convenience samples of speakers with one of eight types of CND. Audio-recorded conversational speech samples from 346 participants with one of eight types of CND were obtained from a database of participants recruited for genetic and behavioural studies of speech sound disorders (i.e., excluding dysfluency) during the past three decades. Data reduction methods for the speech samples included narrow phonetic transcription, prosody-voice coding, and acoustic analyses. Standardized measures were used to cross-classify participants' speech and motor speech status. Compared to the 17.8% prevalence of four types of motor speech disorders reported in a study of 415 participants with idiopathic Speech Delay (SD), 47.7% of the present participants with CND met criteria for one of four motor speech disorders, including Speech Motor Delay (25.1%), Childhood Dysarthria (13.3%), Childhood Apraxia of Speech (4.3%), and concurrent Childhood Dysarthria and Childhood Apraxia of Speech (4.9%). Findings are interpreted to indicate a substantial prevalence of speech disorders, and notably, a substantial prevalence of motor speech disorders in persons with some types of CND. We suggest that diagnostic classification information from standardized motor speech assessment protocols can contribute to research in the pathobiologies of CND.

Abstract
PURPOSE Although speech-language pathologists use parent-delivered home-practice, little is known about the quality of this practice and its relation to treatment efficacy. This study reports both treatment outcomes and fidelity following combined clinician-parent delivery of Rapid Syllable Transition (ReST) treatment. METHOD Five children aged 5:1-11:7 with childhood apraxia of speech received 12 treatment sessions; six clinic-based and six at home, using multiple baselines across participants design. We investigated the children's acquisition of treated pseudo words, generalisation to untreated pseudo and real words, and maintenance of gains. We also assessed parent and clinician treatment fidelity and reliability of perceptual judgements. RESULT Two children improved on all treated behaviours; two showed treatment effect on one of their two treated behaviours, and one child had no treatment effect. Only two children generalised to the majority of untreated items. Variable treatment fidelity was found across parents and aspects of treatment. Child outcome was likely influenced by multiple factors, including treatment fidelity, reliability of perceptual judgements and child factors. CONCLUSION Combined clinician-parent delivery of ReST was less efficacious than previously reported clinician-only delivered ReST. Further investigation of the factors affecting outcome is recommended prior to clinical application of the combined model of service delivery.

Abstract
Although motor training programs have been applied to childhood apraxia of speech (AOS), the neural mechanisms of articulation learning are not well understood. To this aim, we recorded cerebral hemodynamic activity in the left hemisphere of healthy subjects (n = 15) during articulation learning. We used near-infrared spectroscopy (NIRS) while articulated voices were recorded and analyzed using spectrograms. The study consisted of two experimental sessions (modified and control sessions) in which participants were asked to repeat the articulation of the syllables "i-chi-ni" with and without an occlusal splint. This splint was used to increase the vertical dimension of occlusion to mimic conditions of articulation disorder. There were more articulation errors in the modified session, but number of errors were decreased in the final half of the modified session; this suggests that articulation learning took place. The hemodynamic NIRS data revealed significant activation during articulation in the frontal, parietal, and temporal cortices. These areas are involved in phonological processing and articulation planning and execution, and included the following areas: (i) the ventral sensory-motor cortex (vSMC), including the Rolandic operculum, precentral gyrus, and postcentral gyrus, (ii) the dorsal sensory-motor cortex, including the precentral and postcentral gyri, (iii) the opercular part of the inferior frontal gyrus (IFGoperc), (iv) the temporal cortex, including the superior temporal gyrus, and (v) the inferior parietal lobe (IPL), including the supramarginal and angular gyri. The posterior Sylvian fissure at the parietal-temporal boundary (area Spt) was selectively activated in the modified session. Furthermore, hemodynamic activity in the IFGoperc and vSMC was increased in the final half of the modified session compared with its initial half, and negatively correlated with articulation errors during articulation learning in the modified session. The present results suggest an essential role of the frontal regions, including the IFGoperc and vSMC, in articulation learning, with sensory feedback through area Spt and the IPL. The present study provides clues to the underlying pathology and treatment of childhood apraxia of speech.

Abstract
PURPOSE To understand parents' perceptions of Rapid Syllable Transition (ReST) treatment and their experience of either telehealth or combined parent-clinician delivery of speech-language pathology. METHOD Thematic analyses of semi-structured interviews were conducted with 10 parents (5 telehealth, 5 parent-clinician) after their child completed 12 sessions of ReST treatment. RESULTS Three themes were unique to telehealth: "telehealth was a million times easier," "technical problems weren't deal breakers," and "telehealth therapy has different boundaries." Three themes were unique to parent-clinician delivery: "therapy is something to get over and done with," "I wasn't very good at doing therapy," and "my child doesn't like me as his therapist." Both groups had themes related to the significance of childhood apraxia of speech, the importance of specialist treatment, and ReST being a "different way forward." CONCLUSIONS Speech-language pathologists should carefully consider the suitability of caregiver-provided ReST treatment, and increase telehealth delivery of ReST treatment.

Abstract
Purpose
A Phase I pilot study was designed to collect preliminary evidence on the use of the Kaufman Speech to Language Protocol (K-SLP; Kaufman, 2014) to treat children with childhood apraxia of speech. We hypothesized that the K-SLP approach would result in more accurate speech production in targeted words, whereas untrained (control) words and speech sounds would remain unchanged.
Method
A single-case multiple-baseline across behaviors experimental design was used to see if experimental feasibility could be demonstrated. Two children each received a total of 12 1-hr treatment sessions over 3 weeks. The children's response to treatment and experimental control was measured by administering baseline, treatment, and posttreatment probes.
Results
Both children showed some response to treatment, as measured by percent phonemes correct; however, the response to treatment varied. In general, for the treated words that improved with therapy, accuracy was maintained above baseline level during the maintenance phase. Minimal generalization was observed for this study, with only 1 participant generalizing treatment gains to 2 sets of untrained (similar) words.
Conclusion
This Phase I pilot study provides limited preliminary evidence for the effectiveness of the K-SLP approach in treating childhood apraxia of speech in some children under the conditions specified in this study. Replication of these results in well-controlled studies is needed before this structured and operationalized version of the K-SLP approach can be recommended for clinical use.

INTERNATIONAL JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2018; 20:300-309.

Abstract
Evidence-based practice (EBP) is a well-accepted theoretical framework around which speech-language pathologists strive to build their clinical decisions. The profession's conceptualisation of EBP has been evolving over the last 20 years with the practice of EBP now needing to balance research evidence, clinical data and informed patient choices. However, although EBP is not a new concept, as a profession, we seem to be no closer to closing the gap between research evidence and practice than we were at the start of the movement toward EBP in the late 1990s. This paper examines why speech-language pathologists find it difficult to change our own practice when we are experts in changing the behaviour of others. Using the lens of behavioural economics to examine the heuristics and cognitive processes which facilitate and inhibit change, the paper explores research showing how inconsistency of belief and action, or cognitive dissonance, is inevitable unless we act reflectively instead of automatically. The paper argues that heuristics that prevent us changing our practice toward EBP include the sunk cost fallacy, loss aversion, social desirability bias, choice overload and inertia. These automatic cognitive processes work to inhibit change and may partially account for the slow translation of research into practice. Fortunately, understanding and using other heuristics such as the framing effect, reciprocity, social proof, consistency and commitment may help us to understand our own behaviour as speech-language pathologists and help the profession, and those we work with, move towards EBP.

Abstract
BACKGROUND Childhood apraxia of speech (CAS) affects a child's ability to produce sounds and syllables precisely and consistently, and to produce words and sentences with accuracy and correct speech rhythm. It is a rare condition, affecting only 0.1% of the general population. Consensus has been reached that three core features have diagnostic validity: (1) inconsistent error production on both consonants and vowels across repeated productions of syllables or words; (2) lengthened and impaired coarticulatory transitions between sounds and syllables; and (3) inappropriate prosody (ASHA 2007). A deficit in motor programming or planning is thought to underlie the condition. This means that children know what they would like to say but there is a breakdown in the ability to programme or plan the fine and rapid movements required to accurately produce speech. Children with CAS may also have impairments in one or more of the following areas: non-speech oral motor function, dysarthria, language, phonological production impairment, phonemic awareness or metalinguistic skills and literacy, or combinations of these. High-quality evidence from randomised controlled trials (RCTs) is lacking on interventions for CAS. OBJECTIVES To assess the efficacy of interventions targeting speech and language in children and adolescents with CAS as delivered by speech and language pathologists/therapists. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, eight other databases and seven trial registers up to April 2017. We searched the reference lists of included reports and requested information on unpublished trials from authors of published studies and other experts as well as information groups in the areas of speech and language therapy/pathology and linguistics. SELECTION CRITERIA RCTs and quasi-RCTs of children aged 3 to 16 years with CAS diagnosed by a speech and language pathologist/therapist, grouped by treatment types. DATA COLLECTION AND ANALYSIS Two review authors (FL, AM) independently assessed titles and abstracts identified from the searches and obtained full-text reports of all potentially relevant articles and assessed these for eligibility. The same two authors extracted data and conducted the 'Risk of bias' and GRADE assessments. One review author (EM) tabulated findings from excluded observational studies (Table 1). MAIN RESULTS This review includes only one RCT, funded by the Australian Research Council; the University of Sydney International Development Fund; Douglas and Lola Douglas Scholarship on Child and Adolescent Health; Nadia Verrall Memorial Scholarship; and a James Kentley Memorial Fellowship. This study recruited 26 children aged 4 to 12 years, with mild to moderate CAS of unknown cause, and compared two interventions: the Nuffield Dyspraxia Programme-3 (NDP-3); and the Rapid Syllable Transitions Treatment (ReST). Children were allocated randomly to one of the two treatments. Treatments were delivered intensively in one-hour sessions, four days a week for three weeks, in a university clinic in Australia. Speech pathology students delivered the treatments in the English language. Outcomes were assessed before therapy, immediately after therapy, at one month and four months post-therapy. Our review looked at one-month post-therapy outcomes only.We judged all core outcome domains to be low risk of bias. We downgraded the quality of the evidence by one level to moderate due to imprecision, given that only one RCT was identified. Both the NDP-3 and ReST therapies demonstrated improvement at one month post-treatment. A number of cases in each cohort had recommenced usual treatment by their speech and language pathologist between one month and four months post-treatment (NDP-3: 9/13 participants; ReST: 9/13 participants). Hence, maintenance of treatment effects to four months post-treatment could not be analysed without significant potential bias, and thus this time point was not included for further analysis in this review.There is limited evidence that, when delivered intensively, both the NDP-3 and ReST may effect improvement in word accuracy in 4- to 12-year-old children with CAS, measured by the accuracy of production on treated and non-treated words, speech production consistency and the accuracy of connected speech. The study did not measure functional communication. AUTHORS' CONCLUSIONS There is limited evidence that, when delivered intensively, both the NDP-3 and ReST may effect improvement in word accuracy in 4- to 12-year-old children with CAS, measured by the accuracy of production on treated and non-treated words, speech production consistency and the accuracy of connected speech. The study did not measure functional communication. No formal analyses were conducted to compare NDP-3 and ReST by the original study authors, hence one treatment cannot be reliably advocated over the other. We are also unable to say whether either treatment is better than no treatment or treatment as usual. No evidence currently exists to support the effectiveness of other treatments for children aged 4 to 12 years with idiopathic CAS without other comorbid neurodevelopmental disorders. Further RCTs replicating this study would strengthen the evidence base. Similarly, further RCTs are needed of other interventions, in other age ranges and populations with CAS and with co-occurring disorders.

Abstract
PURPOSE The aim of the study was to propose the speech motor learning approach (Van der Merwe, 2011) as a treatment for childhood apraxia of speech and to determine if it will effect positive change in the ability of a 33-month-old child to produce untreated nonwords and words containing treated age-appropriate consonants (Set 1 sounds), untreated age-appropriate consonants (Set 2), and untreated age-inappropriate consonants (Set 3) and also to determine the nature and number of segmental speech errors before and after treatment. METHOD An A-B design with multiple target measures and follow-up was implemented to assess the effects of treatment of Set 1. Effect sizes for whole-word accuracy were determined, and two criterion lines were generated following the conservative dual criterion method. Speech errors were judged perceptually. RESULTS Conservative dual criterion analyses indicated no reliable treatment effect due to rising baseline scores. Effect sizes showed significant improvement in whole-word accuracy of untreated nonwords and real words containing age-appropriate treated sounds and real words containing age-appropriate untreated sounds. The number of errors for all three sound sets declined. Sound distortion was the most frequent error type. CONCLUSIONS Preliminary evidence suggests potentially positive treatment effects. However, rising baseline scores limit causal inference. Replication with more children of different ages is necessary. SUPPLEMENTAL MATERIALS https://doi.org/10.23641/asha.5596708.

Abstract
This study examined changes in speech motor control across a movement transition between sounds within a motor learning task in children with apraxia of speech (CAS) and typical development (TD). It was investigated whether oral articulator movement was refined with practice and whether practice gains generalized to words not included in the practice session. A total of 16 children (ages 5-6) with CAS (n = 8) and TD (n = 8) participated in this study. Novel and real word tokens were produced at three time points. Kinematic data was collected using facial motion tracking at each time point. Children completed a practice session following baseline data collection session that integrated motor learning principles. Three tokens were included in the practice session and the remaining stimuli assessed carryover of practice gains. Kinematic data was then collected immediately following practice and 3 days later. Kinematic analyses were conducted on the movement gesture for the first syllable of each word. Narrow transcription analyses examined speech production accuracy. Children in the CAS group displayed increased consonant and vowel accuracy only for the practised tokens. Adjustments to spatial control and movement variability were observed in the CAS group, though only for practised words. Children in the TD group altered spatial and temporal domains of movement and variability across both practised and non-practised tokens. Interestingly, the CAS group displayed a pattern of increased displacement along with decreased variability, which was not observed in the TD group. The degree to which these findings reflect facilitative or maladaptive changes are discussed. Results are also interpreted in relation to vowel properties, novel/real word status and variable practice of novel and real words.

Abstract
PURPOSE The purpose of this study was to evaluate the role of practice variability, through prosodic variation during speech sound training, in biofeedback treatment for children with childhood apraxia of speech. It was hypothesized that variable practice would facilitate speech sound learning. METHOD Six children ages 8-16 years with persisting speech sound errors due to childhood apraxia of speech participated in a single-subject experimental design. For each participant, 2 speech sound targets were treated with ultrasound visual feedback training: one with prosodic variation (i.e., practicing sound targets in words and phrases spoken fast, slow, loud, as a question, command, and declarative), and one without prosodic variation. Each target was treated for half of the 1-hr session for 14 treatment sessions. RESULTS As measured by standardized effect sizes, all participants showed greater change on generalization probes for sound targets treated under the prosodic variation condition with mean effect sizes (d2) of 14.5 for targets treated with prosodic variation and 8.3 for targets treated without prosodic variation. The average increase in generalization scores was 38% in the prosodic variation condition compared to 31% without. CONCLUSIONS Ultrasound visual feedback may facilitate speech sound learning and learning may be enhanced by treating speech sounds with explicit prosodic variation.

METHOD In a cross-sectional design, 10 adults, 17 typically developing children, and 11 children with SSD repeated carrier phrases with novel words with fricatives (/s/, /ʃ/). Dependent measures were 2 ratios derived from spectral mean, obtained from perceptually accurate tokens. Group analyses compared adults and typically developing children; individual children with SSD were compared to their respective typically developing peers. RESULTS Typically developing children demonstrated smaller fricative acoustic contrast than adults but similar coarticulatory patterns. Three children with SSD showed smaller fricative acoustic contrast than their typically developing peers, and 2 children showed abnormal coarticulation. The 2 children with abnormal coarticulation both had a clinical diagnosis of childhood apraxia of speech; no clear pattern was evident regarding SSD subtype for smaller fricative contrast. CONCLUSIONS Children have not reached adult-like speech motor control for fricative production by age 10 even when fricatives are perceptually accurate. Present findings also suggest that abnormal coarticulation but not reduced fricative contrast is SSD-subtype-specific. SUPPLEMENTAL MATERIALS S1: https://doi.org/10.23641/asha.5103070.
