Background: Continued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers. Aims: In an 11‐week intervention programme, speech–language therapists (SLTs) presented the participating teachers with whole‐class teaching techniques aimed at creating a language and communication‐supporting classroom environment. The effects of the intervention on the language development of the students in the teachers' classes were assessed. Methods & Procedures: A total of 211 first‐ and second‐year students (Mage = 7;6, range = 6;5–8;9) underwent standardized language assessments of receptive and expressive language abilities before and after their teachers' participation in the CPD. The students were divided into intervention and delayed intervention groups to enable randomized intervention allocation. Linear mixed modelling was used to estimate the individual and interaction effects of group, time and demographic factors. Outcomes & Results: Significant effects of time, group and school, respectively, but no interaction between time and group indicates that while all students advanced between assessments, the progress was not attributable to the teachers' participation in the CPD. Conclusions & Implications: Results are discussed in light of those of recent studies of universal services to support optimal language development. WHAT THIS PAPER ADDS: What is already known on this subject: Although inconclusive, previous research indicates that intervention delivered to teachers by SLTs has the potential to improve the language abilities of the students in the teachers' classrooms. What this paper adds to existing knowledge: This study explored the language development of first‐ and second‐year mainstream school students whose teachers took part in a CPD programme aimed at establishing language and communication‐supporting teaching techniques. Results indicate that the development of the students' language abilities could not be attributed to the teachers' participation in the CPD. What are the potential or actual implications of the work?: SLTs are often asked to guide teachers and teaching staff rather than themselves conduct individual assessments and interventions. The results of this trial can be used to inform the discussion on how to prioritize between tasks. [ABSTRACT FROM AUTHOR]

Background: Perceptual, cognitive and previous clinical experience may influence a novice Videofluoroscopic Swallowing Study (VFSS) analyst's trajectory towards competency. Understanding these factors may allow trainees to be better prepared for VFSS training and may allow training to be developed to accommodate differences between trainees. Aims: This study explored a range of factors previously suggested in the literature as influencing the development of novice analysts' VFSS skills. We hypothesised that knowledge of swallow anatomy and physiology, visual perceptual skills, self‐efficacy and interest, and prior clinical exposure would all influence VFSS novice analysts' skill development. Methods & Procedures: Participants were undergraduate speech pathology students recruited from an Australian university, who had completed the required theoretical units in dysphagia. Data assessing the factors of interest were collected—the participants identified anatomical structures on a still radiographic image, completed a physiology questionnaire, completed subsections of the Developmental Test of Visual Processing—Adults, self‐reported the number of dysphagia cases they managed on placement, and self‐rated their confidence and interest. Data for 64 participants relating to the factors of interest were compared with their ability to accurately identify swallowing impairments following 15 h of VFSS analytical training, using correlation and regression analysis. Outcomes & Results: Success in VFSS analytical training was best predicted by clinical exposure to dysphagia cases and the ability to identify anatomical landmarks on still radiographic images. Conclusions & Implications: Novice analysts vary in the acquisition of beginner‐level VFSS analytical skill. Our findings suggest that speech pathologists who are new to VFSS may benefit from clinical exposure to dysphagia cases, sound foundational knowledge of anatomy relevant to swallowing and the ability to see the anatomical landmarks on still radiographic images. Further research is required to equip VFSS trainers and trainees for training, to understand differences between learners during skill development. WHAT THIS PAPER ADDS: What is already known on the subject: The existing literature suggests that no vice Video fluoroscopic Swallowing Study (VFSS) analysts training may be influenced by their personal characteristics and experience. What this study adds: This study found that student clinicians, clinical exposure to dysphagia cases and their ability to identify anatomical landmarks relevant to swallowing on still radiographic images prior to training best predicted their ability to identify swallowing impairments after training. What are the clinical implications of this work?: Given the expense of training health professionals, further research is required into the factors that successfully prepare clinicians for VFSS training, including clinical exposure, foundational knowledge of anatomy relevant to swallowing and the ability to identify the anatomical landmarks on still radiographic images.

Background: A total of 68% of pre‐school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non‐cleft speech disorders. Connected health has been used to address inadequate access to therapy, providing intervention to those who would not otherwise receive therapy. Aims: To evaluate the speech, activity and participation outcomes of Parent Led, Therapist Supervised, Articulation Therapy (PLAT) compared with routine speech therapy intervention in parent–child dyads. Methods & Procedures: A total of 44 children, aged 2.9–7.5 years, were included in a two‐centre, two‐phase randomized controlled trial. Informed consent and assent were obtained. Participants and speech and language therapists (SLTs) were unblinded to the groups. Parents, in the parent‐trained group (n = 23), attended 2 days' training, received a detailed speech therapy programme, and undertook intervention over 12 weeks supported by the cleft specialist SLT using FaceTime and one face‐to‐face session. In the control arm (n = 21), parent–child dyads received six therapy sessions over 12 weeks with a research SLT, comparable with usual care. Speech recordings were undertaken pre‐ and post‐intervention. Percent consonant correct (PCC) was analysed by external SLTs blinded to the time and group. Activity and participation were measured using the Intelligibility in Context Scale (ICS) and Focus on Outcomes for Children Under Six (FOCUS) questionnaire. Outcomes & Results: There was no evidence of an interaction between Time and Group or an overall statistical difference between groups for PCC scores. There was a statistically significant difference over time for both groups (words: p < 0.002; confidence interval (CI) = 9.38–16.27; d = 0.57; sentences: p < 0.002; CI = 16.04–25.97; d = 0.23). Effect sizes were medium for words and small for sentences. For intelligibility and participation, there was no evidence of an interaction between Time and Group or an overall statistical difference between groups. A statistically significant difference over time was found for intelligibility (F = 29.97, d.f. = 1, 42, p < 0.001, 95 % CI = 1.45–3.15 d = 0.46) and for participation (F = 14.19, d.f. = 1, 41, p < 0.001 95% CI = 7.63–25.03; d = 0.36) with FOCUS results indicating clinically meaningful (parent‐led group) and significant (control group) change in participation. Conclusions & Implications: PLAT can be as effective as routine care in changing speech, activity and participation outcomes for children with cleft palate, when supported by a specialist cleft SLT using connected health. What this paper addsWhat is already known on this subjectOver 50% of children with cleft palate require speech therapy. However, there is a lack of timely, accessible speech therapy services in the UK and Ireland. Previous studies have shown that parents can deliver therapy effectively, and that connected health can support the delivery of speech therapy. This study aims to provide evidence that parent‐led therapy with the supervision of a specialist cleft therapist using FaceTime is effective.What this paper adds to existing knowledgeThis randomized controlled trial indicates that parents can be trained to deliver therapy for children with cleft palate speech disorders, under the supervision of an SLT. This approach results in improved speech, activity and participation outcomes similar to routine care.What are the potential or actual clinical implications of this work?This study indicates that both parent‐led articulation therapy and routine care showed meaningful gains in speech, activity and participation, and that parent‐led articulation therapy when supported by a cleft SLT using connected health could be an additional service delivery model for children with cleft palate speech disorders.

Background: Very young children from lower socioeconomic status (SES) backgrounds often show poorer language development. Whilst there have been attempts to provide early intervention programmes, these sometimes miss the most disadvantaged groups. Aims: This report presents preliminary feasibility and effectiveness data for a novel language intervention designed for parents of toddlers in the United Kingdom. Methods and Procedures: In total, 43 UK families of 2–4‐year‐olds were recruited to the study, half of whom completed an 8‐week course (Tots Talking) focussed on parent interaction, and half of whom acted as wait‐list controls. Results and Outcomes: Results suggest that such programmes are feasible for families with 86% staying in the intervention. In addition, greater changes in underlying communication skills such as joint attention and gesture were evident compared to wait‐list controls. Conclusions and Implications: We conclude that pre‐verbal skills may be more important to measure as initial outcomes than language or vocabulary change in this population. What This Paper Adds: What is already known on the subject: Children from lower socioeconomic status (SES) backgrounds are at higher risk of communication difficulties and there is a need for community intervention programmes for very young children. What this study adds: This study suggests that such programmes can be feasible and effective, but that very early/basic communicative skills (such as joint attention) may be boosted first rather than language or vocabulary. What are the clinical implications of this work?: Children's centres and other community services could feasibly run short parent facing courses emphasising contingent communication in low SES families and other diverse groups. These may be more successful run with younger preschoolers. Joint attention may be a better focus of intervention before expecting vocabulary or language change. Community health professionals may find this information useful in referring and supporting families in need. [ABSTRACT FROM AUTHOR]

Background The effectiveness of two treatment approaches (phonological therapy and articulation therapy) for treatment of 14 children, aged 4;0-6;7 years, with phonologically based speech-sound disorder (SSD) has been previously analysed with severity outcome measures (percentage of consonants correct score, percentage occurrence of phonological processes and phonetic inventory). Considering that the ultimate goal of intervention for children with phonologically based SSD is to improve intelligibility, it is curious that intervention studies focusing on children's phonology do not routinely use intelligibility as an outcome measure. It is therefore important that the impact of interventions on speech intelligibility is explored. Aims This paper investigates the effectiveness of the two treatment approaches (phonological therapy and articulation therapy) using intelligibility measures, both in single words and in continuous speech, as the primary outcome. Methods & Procedures Fourteen children with phonologically based SSD participated in the intervention. The children were randomly assigned to phonological therapy or articulation therapy (seven children in each group). Two assessment methods were used for measuring intelligibility: a word identification task (for single words) and a rating scale (for continuous speech). Twenty-one unfamiliar adults listened and judged the children's intelligibility. Reliability analyses showed overall high agreement between listeners across both methods. Outcomes & Results Significant improvements were noted in intelligibility in both single words (paired t(6) = 4.409, p = 0.005) and continuous speech (asymptotic Z = 2.371, p = 0.018) for the group receiving phonology therapy pre- to post-treatment, but no differences in intelligibility were found for those receiving the articulation therapy pre- to post-treatment, either for single words (paired t(6) = 1.763, p = 0.128) or continuous speech (asymptotic Z = 1.442, p = 0.149). Conclusions & Implications Intelligibility measures were sensitive enough to show changes in the phonological therapy group but not in the articulation therapy group. These findings emphasize the importance of using intelligibility as an outcome measure to complement the results obtained with other severity measures when exploring the effectiveness of speech interventions. This study presents new evidence for the effectiveness of phonological therapy in improving intelligibility with children with SSD. [ABSTRACT FROM AUTHOR]

Background: Effortful swallowing training (EST) is a remedial method for the training of swallowing‐related muscles in the oropharyngeal phase. However, clinical evidence of its effectiveness is insufficient. Aims: To investigate the effects of EST on tongue strength and swallowing function in patients with stroke. Methods & Procedures: Stroke patients with dysphagia were randomly assigned to one of two groups: an experimental group (n = 12) and a control group (n = 12). The experimental group underwent EST, while the control group performed saliva swallowing. Training was conducted 5 days per week for 4 weeks. Both groups underwent conventional dysphagia treatment for 30 min/day, 5 days/week for 4 weeks. Outcomes & Results: Tongue strength was assessed using the Iowa Oral Performance Instrument. The Videofluoroscopic Dysphagia Scale (VDS), based on a videofluoroscopic swallowing study, was used to analyze oropharyngeal swallowing function. The experimental group showed greater improvements in anterior and posterior tongue strength compared with the control group (p = 0.046 and 0.042, respectively), and greater improvement in the oral phases of the VDS (p = 0.017). Conclusions & Implications: We recommend EST as a remedial strategy for improving tongue strength and oral swallowing function in patients with stroke. [ABSTRACT FROM AUTHOR]

Background: Electropalatography (EPG) records details of the location and timing of tongue contacts with the hard palate during speech. It has been effective in treating articulation disorders that have failed to respond to conventional therapy approaches but, until now, its use with children and adolescents with intellectual/learning disabilities and speech disorders has been limited. Aims: To evaluate the usefulness of EPG in the treatment of speech production difficulties in children and adolescents with Down syndrome (DS) aged 8–18 years. Methods & Procedures: A total of 27 children with DS were assessed on a range of cognitive and speech and language measures and underwent additional EPG assessment. Participants were randomly allocated to one of three age‐matched groups receiving either EPG therapy, EPG‐informed conventional therapy or 'treatment as usual' over a 12‐week period. The speech of all children was assessed before therapy using the Diagnostic Evaluation of Articulation and Phonology (DEAP) and reassessed immediately post‐ and 3 and 6 months post‐intervention to measure percentage consonants correct (PCC). EPG recordings were made of the DEAP assessment items at all time points. Per cent intelligibility was also calculated using the Children's Speech Intelligibility Measure (CSIM). Outcomes & Results: Gains in accuracy of production immediately post‐therapy, as measured by PCC, were seen for all groups. Reassessment at 3 and 6 months post‐therapy revealed that those who had received therapy based directly on EPG visual feedback were more likely to maintain and improve on these gains compared with the other groups. Statistical testing showed significant differences between groups in DEAP scores across time points, although the majority did not survive post‐hoc evaluation. Intelligibility across time points, as measured by CSIM, was also highly variable within and between the three groups, but despite significant correlations between DEAP and CSIM at all time points, no statistically significant group differences emerged. Conclusions & Implications: EPG was an effective intervention tool for improving speech production in many participants. This may be because it capitalizes on the relative strength of visual over auditory processing in this client group. The findings would seem to warrant an increased focus on addressing speech production difficulties in current therapy. [ABSTRACT FROM AUTHOR]

Abstract: Background: Identifying risk and protective factors for language development informs interventions for children with developmental language disorder (DLD). Maternal responsive and intrusive communicative behaviours are associated with language development. Mother–child interaction quality may influence how children use these behaviours in language learning. Aims: To identify (1) communicative behaviours and interaction quality associated with language outcomes; (2) whether the association between a maternal intrusive behaviour (directive) and child language scores changed alongside a maternal responsive behaviour (expansion); and (3) whether interaction quality modified these associations. Methods & Procedures: Language skills were assessed at 24, 36 and 48 months in 197 community‐recruited children who were slow to talk at 18 months. Mothers and 24‐month‐olds were video‐recorded playing at home. Maternal praise, missed opportunities, and successful and unsuccessful directives (i.e., whether followed by the child) were coded during a 10‐min segment. Interaction quality was rated using a seven‐point fluency and connectedness (FC) scale, during a 5‐min segment. Linear regressions examined associations between these behaviours/rating and language scores. Interaction analysis and simple slopes explored effect modification by FC. Outcomes & Results: There was no evidence that missed opportunities or praise were associated with language scores. Higher rates of successful directives in the unadjusted model and unsuccessful directives in the adjusted model were associated with lower 24‐month‐old receptive language scores (e.g., unsuccessful directives effect size (ES) = −0.41). The association between unsuccessful directives and receptive language was weaker when adjusting for co‐occurring expansions (ES = −0.34). Both types of directives were associated with poorer receptive and expressive language scores in adjusted models at 36 and 48 months (e.g., unsuccessful directive and 48‐month receptive language, ES = −0.66). FC was positively associated with 24‐, 36‐ and 48‐month language scores in adjusted models (e.g., receptive language at 24 months, ES = 0.21, at 48 months, ES = 0.18). Interaction analysis showed the negative association between successful directives and 24‐month receptive language existed primarily in poorly connected dyads with low FC levels. Conclusions & Implications: These findings illustrate the effects of the combined interaction between different maternal communicative behaviours and features of the interaction itself on child language development, and the need to consider both in research and practice. Whilst more intrusive directives were associated with poorer language scores, this association attenuated when adjusting for co‐occurring responsive expansions, and the association was strongest for children in lower quality interactions. This work may inform clinical practice by helping clinicians target the most appropriate communicative behaviours for specific mother–child dyads. [ABSTRACT FROM AUTHOR]

Background There has been little robust evaluation of the outcome of speech and language therapy (SLT) intervention for post-stroke dysarthria. Non-speech oro-motor exercises (NSOMExs) are a common component of dysarthria intervention. A feasibility study was designed and executed, with participants randomized into two groups, in one of which NSOMExs were a component of the intervention programme. Aims To examine (1) operational feasibility of the programme; (2) participants' views of the programme; and (3) speech intelligibility, communication effectiveness and tongue and lip movement at four points (A1 and A2 before, and A3 and A4 after intervention). Methods & Procedures Thirty-nine participants were randomized into Group A ( n = 20) and Group B ( n = 19). Groups were equivalent at enrolment in demographic variables and A1 measures. Intervention was behavioural, delivered in eight home-based SLT sessions, and included practise of individually appropriate words, sentences and conversation, and for Group B also NSOMExs. Between-session practice was recorded in a diary. Data on speech intelligibility, effectiveness of communication in conversation, self-rated situational communication effectiveness, and tongue and lip movement were collected at 8-week intervals, twice before and twice after intervention. Anonymous evaluation (AE) questionnaires were completed. Outcome & Results The recruited number was 20% below the target of 50. Thirty-six participants completed the intervention and 32 were followed through to A4. The programme was delivered to protocol and fidelity was verified. Thirty-four AEs were returned. These showed high satisfaction with the programme and its outcome. According to diary records from 32 participants, 59% carried out at least the recommended practice amount. Outcome measure performance across the four assessment points did not indicate any group effect. For the whole sample both externally rated and self-rated communication effectiveness measures showed statistically significant gains across the intervention period (A2/A3), which were maintained for 2 months after intervention (A2/A4). Non-intervention period changes (A1/A2 and A3/A4) were not present. There were no intervention-related gains in tongue and lip movement or speech intelligibility, but the latter is likely to be attributable to a ceiling effect on scores. Conclusions & Implications The results indicate positive outcomes associated with a short period of behavioural SLT intervention in the post-stroke dysarthria population. The inclusion of NSOMExs, delivered in accordance with standard clinical practice, did not appear to influence outcomes. The results must be viewed in relation to the nature of feasibility study and provide a foundation for suitably powered trials. [ABSTRACT FROM AUTHOR]

Background Little evidence exists for the effectiveness of therapy for children with receptive language difficulties, particularly those whose difficulties are severe and persistent. Aims To establish the effectiveness of explicit speech and language therapy with visual support for secondary school-aged children with language impairments focusing on comprehension of coordinating conjunctions in a randomized control trial with an assessor blind to group status. Methods & Procedures Fourteen participants (aged 11;3-16;1) with severe RELI (mean standard scores: CELF4 ELS = 48, CELF4 RLS = 53 and TROG-2 = 57), but higher non-verbal (Matrices = 83) and visual perceptual skills (Test of Visual Perceptual Skills (TVPS) = 86) were randomly assigned to two groups: therapy versus waiting controls. In Phase 1, the therapy group received eight 30-min individual sessions of explicit teaching with visual support (Shape Coding) with their usual SLT. In Phase 2, the waiting controls received the same therapy. The participants' comprehension was tested pre-, post-Phase 1 and post-Phase 2 therapy on (1) a specific test of the targeted conjunctions, (2) the TROG-2 and (3) a test of passives. Outcomes & Results After Phase 1, the therapy group showed significantly more progress than the waiting controls on the targeted conjunctions ( d = 1.6) and overall TROG-2 standard score ( d = 1.4). The two groups did not differ on the passives test. After Phase 2, the waiting controls made similar progress to those in the original therapy group, who maintained their previous progress. Neither group showed progress on passives. When the two groups were combined, significant progress was found on the specific conjunctions ( d = 1.3) and TROG-2 raw ( d = 1.1) and standard scores ( d = 0.9). Correlations showed no measures taken (including Matrices and TVPS) correlated significantly with progress on the targeted conjunctions or the TROG-2. Conclusions & Implications Four hours of Shape Coding therapy led to significant gains on comprehension of coordinating conjunctions which were maintained after 4 months. Given the significant progress at a group level and the lack of reliable predictors of progress, this approach could be offered to other children with similar difficulties to the participants. However, the intervention was delivered one-to-one by speech and language therapists, thus the effectiveness of this therapy method with other methods of delivery remains to be evaluated.

Background: Telerehabilitation may be a feasible solution to the current problems faced by people with Parkinson's disease in accessing speech pathology services. Aim: To investigate the validity and reliability of online delivery of the Lee Silverman Voice Treatment (LSVT®) for the speech and voice disorder associated with Parkinson's disease. Method & Procedures: Thirty-four participants with Parkinson's disease and mild-to-moderate hypokinetic dysarthria took part in the randomized controlled non-inferiority laboratory trial and received the LSVT® in either the online or the face-to-face environment. Online sessions were conducted via two personal computer-based videoconferencing systems with real-time and store-and-forward capabilities operating on a 128 kbit/s Internet connection. Participants were assessed pre- and post-treatment on acoustic measures of mean vocal sound pressure level, phonation time, maximum fundamental frequency range, and perceptual measures of voice, articulatory precision and speech intelligibility. Outcomes & Results: Non-inferiority of the online LSVT® modality was confirmed for the primary outcome measure of mean change in sound pressure level on a monologue task. Additionally, non-significant main effects for the LSVT® environment, dysarthria severity, and interaction effects were obtained for all outcomes measures. Significant improvements following the LSVT® were also noted on the majority of measures. The LSVT® was successfully delivered online, although some networking difficulties were encountered on a few occasions. High participant satisfaction was reported overall. Conclusions & Implications: Online treatment for hypokinetic dysarthria associated with Parkinson's disease appears to be clinically valid and reliable. Suggestions for future research are outlined.
