Abstract
The purpose of this study was to investigate if multiple oppositions intervention (MOI) generated widespread change in the phonological systems of two children with cleft lip and palate (CLP) and severe speech sound disorders (SSD). We treated two children (ages 5;4 and 5;6) with CLP and severe SSD using MOI for 24 and 29 sessions. We measured the percentage consonants correct (PCC) for target consonants and untreated consonants in non-treatment single words, as well as PCC for connected speech. Data points were collected in the baseline, intervention, and maintenance phase with post-tests conducted immediately after intervention and at 1, 3, 6 and 12 months. Two speech and language therapists (SLTs) unfamiliar with the children performed phonetic transcriptions, and we calculated intra- and inter-rater agreement. We graphed the data, and used permutation tests to analyse the probability that the observed increases in PCC were due to random chance. Both children experienced considerable improvements in PCC across all measures at the first post-test, supporting the impact of MOI on their entire phonological system. The PCC continued to increase during the maintenance phase. By the final post-test, the PCC in connected speech exceeded 90% for both children, reducing their SSD classification to mild. Our findings support that a phonological, contrastive intervention approach targeting multiple consonants simultaneously can create system-wide phonological change for children with CLP and severe SSD. Further research with more participants is needed to strengthen these findings.

Nicoll A, Roulstone S, Williams B, Maxwell M. Understanding capacity for implementing new interventions: A qualitative study of speech and language therapy services for children with speech sound disorder. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2024; 59:1002-1017. [PMID: 37929610 DOI: 10.1111/1460-6984.12979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 10/18/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Many speech sound disorder (SSD) interventions with a long-term evidence base are 'new' to clinical practice, and the role of services in supporting or constraining capacity for practice change is underexplored. Innovations from implementation science may offer solutions to this research-practice gap but have not previously been applied to SSD. AIM To explain variation in speech and language therapy service capacity to implement new SSD interventions. METHODS & PROCEDURES We conducted an intensive, case-based qualitative study with 42 speech and language therapists (SLTs) in three NHS services (n = 39) and private practice (n = 3) in Scotland. We explored therapists' diverse experiences of SSD practice change through individual interviews (n = 28) or self-generated paired (n = 2) or focus groups (n = 3). A theoretical framework (Normalization Process Theory) helped us understand how the service context contributed to the way therapists engaged with different practice changes. OUTCOMES & RESULTS We identified six types ('cases') of practice change, two of which involved the new SSD interventions. We focus on these two cases ('Transforming' and 'Venturing') and use Normalization Process Theory's Cognitive participation construct to explain implementation (or not) of new SSD interventions in routine practice. Therapists were becoming aware of the new interventions through knowledge brokers, professional networks and an intervention database. In the Transforming case, new SSD interventions for selected children were becoming part of local routine practice. Transforming was the result of a favourable service structure, a sustained and supported 'push' that made implementation of the new interventions a service priority, and considerable collective time to think about doing it. 'Venturing' happened where the new SSD interventions were not a service priority. It involved individual or informal groups of therapists trying out or using one or more of the new interventions with selected children within the constraints of their service context. CONCLUSIONS & IMPLICATIONS New, evidence-based SSD interventions may be challenging to implement in routine practice because they have in common a need for therapists who understand applied linguistics and can be flexible with service delivery. Appreciating what it really takes to do routine intervention differently is vital for managers and services who have to make decisions about priorities for implementation, along with realistic plans for resourcing and supporting it. WHAT THIS PAPER ADDS What is already known on the subject Many SSD interventions have an evidence base but are not widely adopted into routine clinical practice. Addressing this is not just about individual therapists or education/training, as workplace pressures and service delivery models make it difficult to change practice. What this paper adds to the existing knowledge This paper applies innovations from implementation science to help explain how what is going on in services can support or constrain capacity for implementing evidence-based SSD interventions. What are the potential or actual clinical implications of this work? Service managers and therapists will have a clearer idea of the time and support they may realistically have to invest for new SSD interventions to be used routinely.

Abstract
OBJECTIVE Speech sound disorder (SSD) describes a 'persistent difficulty with speech sound production that interferes with speech intelligibility or prevents verbal communication'. There is a need to establish which care pathways are most effective and efficient for children with SSD. Comparison of care pathways requires clearly defined, evidence-based, interventions and agreement on how to measure the outcomes. At present, no definitive list of assessments, interventions or outcomes exists. The objective of this umbrella review paper is to provide a rigorous and detailed list of assessments, interventions and outcomes which target SSD in children. DESIGN In December 2022, a systematic search of Ovid Medline, OVID Embase, CINAHL, PsycInfo and Cochrane and a number of grey literature platforms were undertaken. 18 reviews were included, and subsequently 415 primary research articles were assessed for data related to assessments, interventions or outcomes. The AMSTAR (Assessing the Methodological Quality of Systematic Reviews) framework was used to assess the quality of the retained reviews. SETTING Reviews were retained which took place in any setting. PARTICIPANTS The population is children of any age with a diagnosis of SSD of unknown origin. PRIMARY AND SECONDARY OUTCOME MEASURES Reviews reporting outcomes, assessment and interventions for children with SSD. RESULTS Extraction and analysis identified 37 assessments, 46 interventions and 30 outcome measures used in research reporting of SSD. Not all of the listed outcomes were linked to specific outcome measurement tools, but these were measurable through the use of one or more of the assessments extracted from the retained reviews. CONCLUSIONS The findings of this review will be used to develop a Core Outcome Set for children with SSD. The findings are part of a rigorous process essential for advancing healthcare research and practice in the specific area of speech and language therapy for children with SSD.

Abstract
PURPOSE Children with specific language impairment (SLI) might present with speech sound disorder (SSD) and phonological awareness (PA) deficits which put them at risk of potential reading problems. This work aimed to organize an intervention program in Arabic for phonological training and to assess the effect of PA training versus the phonological therapy (PT) for children with SLI and SSD. METHODS The study was carried out on 60 children with comorbid SLI and SSD, aged 5-7 years. Children were equally divided into two groups; each group received language therapy combined with (PT or PA training). Measures of language development, phonological output, and PA were taken before therapy and at 4 month post-therapy for all children. RESULTS The two therapy groups made nearly the same amount of progress in the development of language and phonological production, with no significant differences regarding language age and percent of consonants correct (PCC). The PA training group progressed more on the PA skills than children who received PT over the same time. CONCLUSIONS PA training could facilitate the development of phonological skills by targeting the child's awareness of phonemes and improving the production of sound patterns.

Abstract
INTRODUCTION Evidence suggests that over one-third of young children with developmental language disorder (DLD) or speech sound disorder (SSD) have co-occurring features of both. A co-occurring DLD and SSD profile is associated with negative long-term outcomes relating to communication, literacy and emotional well-being. However, the best treatment approach for young children with this profile is not understood. The aim of the proposed review is to identify intervention techniques for both DLD and SSD, along with their shared characteristics. The findings will then be analysed in the context of relevant theory. This will inform the content for a new or adapted intervention for these children. METHODS AND ANALYSIS This search will build on a previous systematic review by Roulstone et al (2015) but with a specific focus on oral vocabulary (DLD outcome) and speech comprehensibility (SSD outcome). These outcomes were identified by parents and speech and language therapists within the prestudy stakeholder engagement work. The following databases will be searched for articles from January 2012 onwards: Ovid Emcare, MEDLINE Complete, CINAHL, APA PsycINFO, Communication Source and ERIC. Two reviewers will independently perform the title/abstract screening and the full-text screening with the exclusion criteria document being revised in an iterative process. Articles written in languages other than English will be excluded. Data will be extracted regarding key participant and intervention criteria, including technique dosage and delivery details. This information will then be pooled into a structured narrative synthesis. ETHICS AND DISSEMINATION Ethical approval is not needed for a systematic review protocol. Dissemination of findings will be through peer-reviewed publications, social media, and project steering group networks. PROSPERO REGISTRATION NUMBER CRD4202237393.

Abstract
Speech is a powerful, natural mode of communication that facilitates effective interactions in human societies. However, when fluency or flow of speech is affected or interrupted, it leads to speech impairment. There are several types of speech impairment depending on the speech pattern and range from mild to severe. Childhood apraxia of speech (CAS) is the most common speech disorder in children, with 1 out of 12 children diagnosed globally. Significant advancements in speech assessment tools have been reported to assist speech-language pathologists diagnosis speech impairment. In recent years, speech assessment tools have also gained popularity among pediatricians and teachers who work with preschoolers. Automatic speech tools can be more accurate for detecting speech sound disorders (SSD) than human-based speech assessment methods. This systematic literature review covers 88 studies, including more than 500 children, infants, toddlers, and a few adolescents, (both male and female) (age = 0-17) representing speech impairment from more than 10 countries. It discusses the state-of-the-art speech assessment methods, including tools, techniques, and protocols for speech-impaired children. Additionally, this review summarizes notable outcomes in detecting speech impairments using said assessment methods and discusses various limitations such as universality, reliability, and validity. Finally, we consider the challenges and future directions for speech impairment assessment tool research.

Abstract
The differentiation between subtypes of speech sound disorder (SSD) and the involvement of possible underlying deficits is part of ongoing research and debate. The present study adopted a data-driven approach and aimed to identify and describe deficits and subgroups within a sample of 150 four to seven-year-old Dutch children with SSD. Data collection comprised a broad test battery including the Computer Articulation Instrument (CAI). Its tasks Picture Naming (PN), NonWord Imitation (NWI), Word and NonWord Repetition (WR; NWR) and Maximum Repetition Rate (MRR) each render a variety of parameters (e.g., percentage of consonants correct) that together provide a profile of strengths and weaknesses of different processes involved in speech production. Principal Component Analysis on the CAI parameters revealed three speech domains: (1) all PN parameters plus three parameters of NWI; (2) the remaining parameters of NWI plus WR and NWR; (3) MRR. A subsequent cluster analysis revealed three subgroups, which differed significantly on intelligibility, receptive vocabulary, and auditory discrimination but not on age, gender and SLPs diagnosis. The clusters could be typified as three specific profiles: (1) phonological deficit; (2) phonological deficit with motoric deficit; (3) severe phonological and motoric deficit. These results indicate that there are different profiles of SSD, which cover a spectrum of degrees of involvement of different underlying problems.

Abstract
OBJECTIVES The purposes of this study were to (a) examine children's access to services for their speech and language disorders during their lifetimes; (b) identify any child, disorder, and family characteristics associated with access to services; and (c) describe the speech and language service providers among children who received care. STUDY DESIGN Data from the 2012 National Health Interview Survey were used for this retrospective cohort study. Our sample included 491 children (ages 3;0-17;11 [years;months]) with speech disorders and 333 children with language disorders. We measured the receipt of services for speech or language difficulties (main outcome) and the type of professional providing services (secondary outcome). We examined associations between services and child, disorder, and family characteristics. RESULTS Approximately 75% of children with speech and language disorders had ever received services for their difficulties. Privately insured children and children with co-occurring conditions were more likely to receive services than their peers who were uninsured (speech: 6.1 [1.7,21.3]; language: 6.6 [1.3,32.9]) and had no co-occurring conditions (speech: 2.1 [1.2,3.9]; language: 2.9 [1.5,5.5]). Speech-language pathologists (SLPs) were the most commonly reported provider of services (speech: 68%, language: 60%) followed by early interventionists. CONCLUSIONS Most children with speech and language disorders received services. However, disparities existed by race/ethnicity, health insurance type, co-occurring diagnoses, and disorder duration (speech only). Most children who received services were being provided with care by the experts of speech and language: SLPs. Updated population-based data and implementation studies are needed to document speech and language screening, referral, and access to services.

Abstract
BACKGROUND Speech and language acquisition can be a challenge for young children with Down syndrome (DS), and while early intervention is important, we do not know what early interventions exist and how effective they may be. AIMS To systematically review existing early speech, language and communication interventions for young children with DS from birth up to 6 years, and to investigate their effectiveness in improving speech, language and communication outcomes in children with DS. Other outcomes are changes in parental behaviour and their responsiveness METHODS & PROCEDURES: We conducted a systematic search of relevant electronic databases to identify early intervention studies targeting speech, language and communication outcomes in children with DS published up to May 2020. A total of 11 studies that met the inclusion criteria were synthesized and appraised for quality using the PEDro-P scale. There were a total of 242 children. We identified three types of intervention: communication training and responsive teaching, early stimulation programme, and dialectic-didactic approach. MAIN CONTRIBUTION The findings from nine out of the 11 studies reported positive outcomes for children's language and communication up to 18 months following the intervention. All nine studies reported interventions that were co-delivered by parents and clinicians. However, there was also a de-accelerated growth in requesting behaviours in the intervention group reported by one study as well as a case of no improvement for the intervention group. Three studies provided some evidence of improvements to parent outcomes, such as increased parental language input and increased responsiveness. However, there was a moderate to high risk of bias for all studies included. CONCLUSIONS The findings from this review suggest that interventions that have high dosage, focus on language and communication training within a naturalistic setting, and are co-delivered by parents and clinicians/researchers may have the potential to provide positive outcomes for children with DS between 0 and 6 years of age. Due to the limited number of studies, limited heterogeneous data and the moderate to high risk of bias across studies, there is an urgent need for higher quality intervention studies in the field to build the evidence base. WHAT THIS PAPER ADDS What is already known on the subject Speech and language acquisition is usually delayed in children with DS, yet there are currently no standard interventions for children under 6. A number of research-based interventions exist in the literature, yet it is unknown how effective these are. What this study adds to existing knowledge This is the first systematic review that specifically and exclusively focuses on parent- and non-parent-mediated speech, language and communication interventions for children with DS between 0 and 6 years of age. It complements three existing recent reviews, each of which has a slightly different focus. The previously published reviews have covered only parent-mediated interventions, excluding interventions not mediated by parents, have reviewed interventions including children and adults, without any mention of what early interventions may be like or how effective these may be for young children with DS, have not always assessed risk of bias or have focused specifically on language interventions excluding those focusing on speech articulation or pre-linguistic skills. The findings from the current review suggest that interventions that have high dosage focus on language and communication training within a naturalistic setting and are co-delivered by parents and clinicians/researchers may have the potential to provide positive outcomes for children with Diwn syndrome from 0 to 6. We acknowledge that the current evidence base comes from studies with moderate to high risk of bias, hence our conclusions are not definitive. What are the potential or actual clinical implications of this work? Speech and language therapists will have synthesized information and a quick reference point on what type of interventions exist for children with DS under the age of 6, and evidence of which intervention approaches may be promising in terms of providing positive outcomes. However, it is acknowledged that, due to the limited number of studies and the moderate to high risk of bias inherent in the evidence, there is an urgent need for higher quality intervention studies in the field to build the evidence base.

Background: The treatment of functional speech sound disorders (SSDs) in children is often lengthy, ill-defined, and without satisfactory evidence of success; effectiveness studies on SSDs are rare. This randomized controlled trial evaluates the effectiveness of the integrated SSD treatment program PhonoSens, which focuses on integrating phonological and phonetic processing according to the Integrated Psycholinguistic Model of Speech Processing (IPMSP). Methods: Thirty-two German-speaking children aged from 3.5 to 5.5 years (median 4.6) with functional SSD were randomly assigned to a treatment or a wait-list control group with 16 children each. All children in the treatment group and, after an average waiting period of 6 months, 12 children in the control group underwent PhonoSens treatment. Results: The treatment group showed more percent correct consonants (PCC) and a greater reduction in phonological processes after 15 therapy sessions than the wait-list control group, both with large effect sizes (Cohen’s d = 0.89 and 1.04). All 28 children treated achieved normal phonological abilities: 21 before entering school and 7 during first grade. The average number of treatment sessions was 28; the average treatment duration was 11.5 months. Conclusion: IPMSP-aligned therapy is effective in the treatment of SSD and is well adaptable for languages other than German.

Abstract
PURPOSE While many examples of speech pathology intervention approaches for children with speech sound disorders (SSDs) exist in English and some other European languages, approaches with children in other languages are largely unknown. The aim was to determine current speech-language pathologists (SLPs) intervention practices with children with SSDs in the ME, and to then compare these with international practices. METHODS Data were collected by online questionnaire using Qualtrics. One hundred and eighty-nine SLPs completed the survey. Participants were required to be Arabic first language speaking SLPs practicing in the ME (e.g. Kuwait, Saudi Arabia, UAE, and Egypt), working with children with SSDs. RESULTS The respondents reported a frequent use of phonological awareness, traditional articulation therapy, auditory discrimination, minimal pairs, and whole language therapy approaches in the treatment of children with SSDs, like their counterparts in Australia, the USA, UK, and Portugal. Gaps between research recommendations for evidence-based practice and actual clinical practice are identified, and discussed. CONCLUSIONS Future research should investigate the efficacy of speech-therapy approaches to improve service delivery for Arabic-speaking children with SSDs in the ME.

Abstract
BACKGROUND NHS case note data are a potential source of practice-based evidence which could be used to investigate the effectiveness of different interventions for individuals with a range of speech, language and communication needs. Consistency in pre- and post-intervention data as well as the collection of relevant variables would need to be demonstrated as a precursor to adopting this approach in future investigations of speech and language therapy intervention. AIMS To explore whether routine clinical data collection for children with speech sound disorder (SSD) could be a potential source for examining the effectiveness of intervention(s). METHODS & PROCEDURES We examined case notes from three UK NHS services, reviewing 174 sets of case notes and 234 blocks of therapy provided for school-age children with SSD. MAIN CONTRIBUTION We found there was significant variation in pre- and post-intervention data and variables collected by the services. The assessment data available in the case notes across all sites were insufficient to be used to compare the effectiveness of different interventions. Specific issues included lack of consistent reporting of pre- and post-intervention data, and use of a variety of both formal and informal assessment tools. CONCLUSIONS & IMPLICATIONS The case notes reviewed were from three sites and may not represent wider clinical practice, nevertheless the findings suggest the sample explored indicates the need for more consistent and contemporaneous collection of data for children with SSD to facilitate the investigation of different interventions in practice. Researchers should work with the clinical community to determine a minimal dataset that includes a core outcome set and potential variables. This should be feasible to collect in clinical practice and provide a dataset for future investigations of clinically relevant research questions. This would provide an invaluable resource to the clinical academic and research communities enabling research questions to be addressed that have the potential to lead to improved outcomes and more cost-effective services. WHAT THIS PAPER ADDS What is already known on the subject While there is some evidence for the efficacy of therapy for children with SSD, studies typically focus on very specific populations who meet strict selection criteria and take place in university clinics or laboratory-style settings which do not reflect typical clinical practice in the UK and elsewhere. An alternative approach to investigating the effectiveness of interventions would be to use NHS case note data. It is not clear from the existing literature whether case note data are sufficiently robust to facilitate such an analysis. What this paper adds to existing knowledge This study found that case note data, in particular assessment data, were highly variable across services and would be insufficient to compare different interventions for this population. Agreement on what should be included in a minimal dataset for children with SSD is required to maximize the potential for NHS clinical case notes to become a resource for future research. What are the actual or potential clinical implications of this work? This study indicates that current clinical practice in SLT for children with SSD is inconsistent with regards to the reporting of pre- and post-intervention assessment data and other important variables in case notes. We make the case for agreeing a minimal dataset with a need for clinicians to work with researchers to determine core outcomes and additional relevant data, which can be feasibly collected in clinical practice.

Abstract
Purpose The aim of this study was to extract key learning from intervention studies in which qualitative aspects of dosage, dose form, have been examined for children with developmental language disorder (DLD)-in vocabulary, morphosyntax, and phonology domains. This research paper emerged from a pair of systematic reviews, aiming to synthesize available evidence regarding qualitative and quantitative aspects of dosage. While quantitative aspects had been experimentally manipulated, the available evidence for dose form (tasks or activities within which teaching episodes are delivered) was less definitive. Despite this, the review uncovered insights of value to DLD research. Method A preregistered systematic review (PROSPERO ID: CRD42017076663) adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was completed. Included papers were quasi-experimental, randomized controlled trial, or cohort analytic studies, published in any language between January 2006 and May 2019; oral language interventions with vocabulary, morphosyntax, or phonology outcomes; and participants with DLD (M = 3-18 years). The intention was to include papers in which dose form was experimentally manipulated or statistically analyzed, while quantitative dosage aspects were controlled, such that definitive conclusions about optimal dose form could be drawn and gaps in the evidence identified. Results Two hundred and twenty-four papers met the above inclusion criteria; 27 focused on dose form. No study controlled for all quantitative aspects of dosage such that we could effectively address our original research questions. Despite this, key points of learning emerged with implications for future research. Conclusions There is tentative evidence of advantages for explicit over implicit instruction and of the benefits of variability in input, elicited production, and gestural and other visual supports. With careful design of dose form, there is potential to design more efficient interventions. Speech-language pathology research would benefit from an agreed taxonomy of dose form components and standardized reporting of intervention studies, to enable cross-study comparisons and a systematic accrual of knowledge to identify optimal dose form for clinical application.

Abstract
Purpose Children with speech sound disorders feature prominently on the caseloads of speech-language pathologists working in schools, with many receiving services once or twice weekly for 20-30 min. This study compared the outcomes of services provided twice weekly for 30 min to those provided 4 times weekly for 15 min to examine their effectiveness in remediating speech sound disorders in an elementary school setting. Method A total of 35 students were recruited from an existing public school caseload for participation. Participants were randomly assigned to receive school-based speech therapy services for either 30 min twice weekly or 15 min 4 times weekly. There were no differences between groups in age, gender, or the amount of time spent in general education. Growth was measured by the percentage of Individualized Education Program goals mastered and the percentage of sounds produced correctly in isolation. Results After one calendar year, there was a negligible difference between groups on both the percentage of Individualized Education Program goals mastered and the percentage of sounds produced correctly in isolation. On average, both scheduling configurations were effective in meeting students' needs. Conclusions The results of this study suggest that children with speech sound disorders receiving school-based speech therapy services can benefit from a variety of scheduling options. Awareness of such options is an invaluable resource to speech-language pathologists wanting to provide effective and efficient services. Future research should continue investigating service delivery models' effects in applied settings.

Identification of the factors associated with the severity of the speech production problems in children with comorbid speech sound disorder and developmental language disorder.

Abstract
It has been suggested that factors such as auditory perception, oral motor skills, phonological awareness, and working memory are all associated with speech production problems in children with speech sound disorder (SSD) and developmental language disorder (DLD). However, it remains unclear whether the severity of the speech production problems in these children can be explained by an interaction among the aforementioned factors. The aim of this study was to determine which of these four factors best explain the severity of the speech production problems in children with SSD and DLD and whether an interaction between factors occurs. Forty-one children with SSD and DLD between 5 and 5;11 years old were selected. The number of phonological process errors was used as a measure of the severity of the speech production problems. The association between the number of phonological process errors and performance in auditory perception, oral motor skills, phonological awareness, and working memory along with the severity of the DLD was explored using univariate and multivariate regression models (with and without an interaction term). The results showed that the number of phonological process errors was largely explained by working memory and phonological awareness. An interaction between these two factors was also found. This means that working memory and phonological awareness interact to have an effect on the number of phonological process errors that is more than the sum of their parts. In addition, the severity of the DLD was significantly associated with the number of phonological process errors. These findings suggest that phonological awareness and working memory should be considered when assessing and treating children with comorbid SSD and DLD.

Abstract
BACKGROUND Systematic reviews of treatment trials for children with speech and language difficulties often exemplify the limited clinical usefulness of the evidence base, reflecting recent literature in evidence-based medicine. Other studies report that clinicians often fail to seek information about best practice, across the health professions. Consequently, clinical researchers, including those in speech-language pathology, have sought alternative methodologies for determining best practice. SUMMARY Some approaches focus on "pragmatic trials," usually as part of existing health services. Others place case management of individuals at the centre of intervention presenting studies of one or more cases, including N-of-1 randomized controlled trials and cross-over group designs. Clinical case studies can provide important theoretical data contributing to our understanding of the development of typical and atypical communication. Precision medicine (also known as personalized medicine) is an emerging approach to building the clinical evidence base that acknowledges the importance of individual genetic and environmental differences between people. With increasing knowledge of aetiological heterogeneity, even within children presenting with the same diagnosis (e.g., childhood apraxia of speech), data reinforce the edict that children are not all born equal. Key Message: This review argues that to understand response to treatment, it is critical to examine child-related factors as well as the variables of the intervention itself.

'It depends': Characterizing speech and language therapy for preschool children with developmental speech and language disorders. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2019; 54:954-970.

Abstract
BACKGROUND Several studies have suggested that practitioners hold speech and language therapy (SLT) practice as tacit and consequently it is difficult for the therapist to describe. The current study uses a range of knowledge elicitation (KE) approaches, a technique not used before in SLT, as a way of accessing this tacit knowledge. There is currently no agreed framework that establishes key factors underpinning practice for preschool children with speech and language disorders. This paper attempts to address that gap. AIMS To develop a framework of SLTs' practice when working with preschool children with developmental speech and language disorders (DS&LD). METHODS & PROCEDURES A mixed-methods approach was adopted for this study. Data were collected iteratively, from 245 SLTs with experience of working with preschool children with DS&LD across sites in England, by means of focus groups and national events. There were three stages of data collection: local sites, specific-interest groups and two national events. KE techniques were used to gather data, with initial data being collected in local site focus groups. Findings from groups were taken to subsequent larger groups where a combination of concept mapping, teach-back and sorting exercises generated a more detailed description of practice, using discussion of consensus and disagreement to stimulate further exploration and definition and provide validatory evidence. OUTCOMES & RESULTS This paper provides a high-level framework of therapy for preschool children with DS&LD that makes practice explicit in this area. The framework proposes that therapists' aims for this group of children fall into three categories: addressing children's areas of impairment and skills; achieving functionally meaningful skills and carryover; and supporting adults to provide a supportive communication environment. The exact configuration is shaped by the child's context and needs. CONCLUSIONS & IMPLICATIONS The framework highlights themes that are well researched in the literature (e.g., speech) and others that have been little studied (e.g., adult understanding), indicating a disconnect between research evidence and practice. The research also highlights the complex nature of interventions for preschool children with DS&LD and the importance therapists attribute to tailoring therapy to individual needs. The framework provides a scaffold upon which SLTs can focus their clinical practice and encourages the profession to understand and explore better the gaps between research evidence and clinical practice for preschool children with DS&LD.

Abstract
The aim of this study is to examine the efficacy and applicability of the maximal opposition approach to treatment of an Arabic-speaking child with a phonological disorder. A 4:2 year old Jordanian boy, born and raised in Kuwait, received phonological therapy using a maximal opposition approach with major-class distinctions, using a single-case experimental design. The child's speech production accuracy improved. Success with this one child suggests phonological contrast therapy-specifically a maximal opposition approach-could be used to treat other Arabic-speaking children who present with phonological disorders. More research is required before the most appropriate technique and treatment frequency for Arabic speaking children can be determined.

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.

INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2018; 53:995-1006. [PMID: 30047190 DOI: 10.1111/1460-6984.12416] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Revised: 06/18/2018] [Accepted: 06/29/2018] [Indexed: 06/08/2023]
Abstract
BACKGROUND Across the world, research has shown that intervention for children with phonological impairment can be both effective and efficient. However, it has also raised concerns about the translation of this evidence to practice, highlighting questions around clinician knowledge and the understanding of approaches, and the intensity of intervention provided within real-life clinical contexts. AIMS To investigate the clinical management of phonological impairment by speech and language therapists (SLTs) in the United Kingdom (UK). METHODS & PROCEDURES An anonymous, UK-wide, online survey was developed using Qualtrics. The target audience were UK-based SLTs who worked with children with phonological impairment. The following topics were explored: (1) SLTs' understanding of intervention approaches; (2) SLTs' use of intervention approaches to treat phonological impairment; and (3) SLTs' provision of intervention intensity for children with phonological impairment. OUTCOMES & RESULTS A total of 166 responses were analyzed. To remediate phonological impairment, SLTs most commonly used speech discrimination (79.5%), conventional minimal pairs (77.3%), phonological awareness therapy (75.6%) and traditional articulation therapy (48.4%). Participants least frequently used the complexity approaches targeting the empty set (82.9%) and two- to three-element clusters (75%) as well as the cycles approach (75.6%). Results also showed that some SLTs were uncertain of what the empty set and two- to three-element clusters approaches entailed. In terms of intervention intensity, participants predominantly provided intervention once per week (69%) for a total of 9-12 sessions (ranging from five to 30 sessions, 71.5%) and elicited targets 10-30 times in single words per session (59.4%) in sessions lasting 21-30 min (41.4%). CONCLUSIONS & IMPLICATIONS The most commonly used intervention approaches identified in the current survey (i.e., speech discrimination, conventional minimal pairs and phonological awareness therapy) may be used eclectically by SLTs, which could impact upon the effectiveness and efficiency of treatment for phonological impairment. The current study also highlighted that almost half the participants always/often used traditional articulation therapy to remediate phonological impairment, even though this approach has been found to be less effective for this difficulty. Additionally, it appears that the currently provided intervention intensity for phonological impairment in the UK is significantly lower than what is indicated in the literature. Therefore, a research-practice gap exists for SLTs in the UK working with children with phonological impairment.
