Background: Individuals with developmental language disorder or Williams syndrome are reported to use more gestures than individuals with typical development. However, these two groups differ considerably in visuospatial and language skills, two skills that are hypothesized to shape gesture rate. Aims: We first examined whether children with both developmental language disorder and children Williams syndrome do indeed use more gestures. Our second aim was to disentangle the role of vocabulary and visuospatial skills in the use of supplementary gestures (i.e., containing unique information). To account for participant heterogeneity, analyses included both group comparisons and vocabulary and visuospatial skills at an individual level. As a third aim, the role of visuospatial skills was further examined in relation to gestures containing spatial content. Methods & Procedures: In a cross‐sectional group design, three participant groups watched and then retold a cartoon: children with typical development (n = 25), children with developmental language disorder (n = 25) and children/young people with Williams syndrome (n = 14). Their narrations were transcribed and hand gestures were coded based on gesture–speech integration (redundant, adds information to particular lexical items, gives information that is entirely absent from speech) and spatial content. Participants' expressive vocabulary and visuospatial skills were measured. Outcomes & Results: Between‐group comparisons showed that individuals with developmental language disorder or Williams syndrome did indeed use more gestures. Poisson loglinear modelling demonstrated that a relative higher use of supplementary gestures was determined by lower expressive vocabulary skills. Neither the group distinction nor visuospatial skills shaped the supplementary gesture rate nor spatial gesture rate. Conclusions & Implications: Regardless of neurodevelopmental condition or typical development, a higher use of supplementary gestures was influenced by expressive vocabulary skills. Children with lower vocabulary skills spontaneously capitalized on the multimodality of communication to express constituents that were not present in their verbal speech. This finding is a promising starting point for future gesture intervention studies examining whether implicit modelling of gesture use can encourage gestures even more in these children and if this allows them to achieve higher linguistic complexity. On a methodological note, the observed intra‐group skill variability demonstrates that group comparisons need to be complemented with correlational measures accounting for skills at an individual level. What this paper adds: What is already known on the subject: Children with developmental language disorder and children with Williams syndrome are more inclined to use gestures than typically developing children. Research conducted in adults with typical development points towards the role of lexical and visuospatial skills in gesture use, but it is unclear how these skills shape gesture use in children with atypical development. What this paper adds to existing knowledge: This study compares the rate of gestures that convey meaning that is not expressed in speech between the three aforementioned populations. Novel is the inclusion of the group distinction, individual lexical skills, and visuospatial skills in one encompassing statistical model. What are the potential or actual clinical implications of this work?: The inclination to use gestures that replace speech is related to lexical skills. Visuospatial skills do not seem to play a role and should not be considered as a factor when thinking about gesture intervention. Understanding how gestures relate to specific skills is a first step to understanding how gesture interventions can bolster language production. [ABSTRACT FROM AUTHOR]

Background: Acute and late toxicities in patients treated with (chemo)radiotherapy for head and neck cancer (HNC) is common and can negatively impact quality of life and performance. Performance status instruments measure the functional ability to perform daily life activities and are important tools in the oncologic population. Aims: Since Dutch performance status scales for the HNC population are lacking, we conducted this study to translate the Performance Status Scale for Head and Neck Cancer Patients (PSS‐HN) into Dutch (D‐PSS‐HN) and to validate this version. Methods & Procedures: The D‐PSS‐HN was translated into Dutch according to the internationally described cross‐cultural adaptation process. It was administered to HNC patients and together with the Functional Oral Intake Scale completed by a speech and language pathologist at five different time points during the first 5 weeks of (chemo)radiotherapy. Patients were asked each time to complete the Functional Assessment of Cancer Therapy and the Swallowing Quality of Life Questionnaire. Pearson correlation coefficients were used to calculate convergent and discriminant validity and the evolution of D‐PSS‐HN scores was assessed by means of linear mixed models. Outcomes & Results: A total of 35 patients were recruited and > 98% of the clinician‐rated scales were completed. Convergent and discriminant validity were demonstrated, with all correlations rs between 0.467 and 0.819, and between 0.132 and 0.256, respectively. The subscales of the D‐PSS‐HN are sensitive to detect changes through time. Conclusion & Implications: The D‐PSS‐HN is a valid and reliable instrument to assess performance status in patients with HNC treated with (chemo)radiotherapy. It is a useful tool to measure HNC patients' current diet level and functional abilities to perform daily life activities. WHAT THIS PAPER ADDS: What is already known on the subject: Acute and late toxicities in patients treated with (chemo)radiotherapy for HNC are common and can negatively impact quality of life and performance. Performance status instruments measure the functional ability to perform daily life activities and are important tools in the oncologic population. However, Dutch performance status scales for the HNC population are lacking. Therefore, we translated the Performance Status Scale for Head and Neck Cancer Patients (PSS‐HN) into Dutch (D‐PSS‐HN) and validated this version. What this paper adds to existing knowledge: We translated the PSS‐HN and demonstrated its convergent and discriminant validity. The subscales of the D‐PSS‐HN are sensitive to detect changes through time. What are the potential or actual clinical implications of this work?: The D‐PSS‐HN is a useful tool to measure HNC patients' functional abilities to perform daily life activities. The tool can easily be used in clinical settings: since data collection duration is very short, this facilitates clinical (and research‐related) implementation of the scale. Patients' individual needs could be identified by using the D‐PSS‐HN, resulting in more appropriate approaches and (early) referrals if needed. Interdisciplinary communication could be facilitated.

Background: While implementation studies in aphasia management have shown promising improvements to clinical practice, it is currently unknown if aphasia implementation outcomes are sustained and what factors may influence clinical sustainability. Aims: To evaluate the sustainment (i.e., sustained improvement of aphasia management practices and domains influencing clinicians' practice) and sustainability (i.e., factors influencing sustainability) outcomes of the Acute Aphasia IMplementation Study (AAIMS). Methods & Procedures: A convergent interactive mixed‐methods sustainability evaluation was conducted on two previously delivered implementation interventions (AAIMS). The AAIMS interventions were targeted at improving either written aphasia‐friendly information provision (Intervention A) or collaborative goal‐setting (Intervention B). Outcomes were collected 2 and 3 years post‐implementation, addressing the research questions of sustainment (e.g., medical record audits and behavioural constructs questionnaires) and sustainability (e.g., post‐study focus groups and organizational readiness surveys). Quantitative sustainability data were compared with post‐implementation data, allowing for sustainment to be determined. Clinicians' perspectives on sustainability outcomes and challenges were analysed using framework analysis and integrated with the quantitative findings. Outcomes & Results: A total of 35 speech–language therapists (SLTs) from four hospitals participated. The medical records of 79 patients were audited in the sustainability period compared with the 107 medical records audited during AAIMS. Overall, there was variable sustainment of the target behaviours; implementation for Intervention A was not sustained at either sustainability time point (2018 = 47.8% decrease; 2019 = 22.78% decrease), but implementation for Intervention B was sustained at both time points (2018 = 7.78% increase; 2019 = 18.1% increase). There was a pattern of sustained change in the behaviour change domains targeted by the implementation interventions, where scores of the targeted domains increased over time (0.13, 95% confidence interval (CI) = −0.05 to 0.30) and scores of the non‐targeted domains declined (−0.03, 95% CI = −0.11 to 0.04). Factors influencing sustainability were mainly related to 'processes', 'the inner context' and 'SLT characteristics', and these interacted dynamically to account for variation between teams. Conclusions & Implications: Implementation outcomes (i.e., practice changes) were not sustained to the same level for three of the four participating SLT teams, with variable or partial sustainment most common. While the factors influencing sustainability differed depending on the context and individuals involved, the most important factor influencing outcomes seemed to be the level to which behaviour‐change processes and strategies were embedded within the SLT department. Future implementation studies should incorporate sustainability measures from the onset and include follow‐ups and monitoring systems to help support sustained change in the long term. What this paper adds: What is already known on the subject: In post‐stroke aphasia management, there are few examples of long‐term sustainability of implementation outcomes. It is therefore unknown what factors are potentially important to sustain implementation of best‐practice recommendations in aphasia services. What this paper adds to existing knowledge: There is potential for implementation outcomes to be sustained long term, but sustainment is impacted by a range of factors. Ongoing facilitation or follow‐up after initial implementation may to useful to promote sustainment, but is not essential if processes are sufficiently embedded. Gradual implementation into practice may lead to better sustainment than rapid change that is quickly forgotten. What are the potential or actual clinical implications of this work?: Future implementation efforts should incorporate sustainability measures from the onset. Applying a sustainability framework was useful to guide evaluations and explore factors influencing the sustainment outcomes and is recommended for those interested in sustainability. Results from our evaluation can be used to guide refinement and support future development of sustainable implementation interventions. [ABSTRACT FROM AUTHOR]

Background: Studies suggest swallow intervention programmes that incorporate visual biofeedback and motor programming principles can improve swallowing and quality of life for people with idiopathic Parkinson's disease (IPD) and dysphagia. Few studies have examined outcomes using instrumentation. Aims: Using fibreoptic endoscopic examination of swallowing (FEES), this study examines the effectiveness of a neurorehabilitation intervention involving biofeedback via surface electromyography (sEMG) to improve swallowing in people with IPD, and to explore the feasibility of the intervention approach. Methods & Procedures: We recruited 12 participants with IPD and dysphagia. A total of 10 completed the study. Intervention was delivered for 1 h per day, 5 days per week, for 4 weeks (20 h). Swallowing tasks using sEMG biofeedback incorporated principles of motor learning and neuroplasticity. Instrumental and non‐instrumental assessment, including quality‐of‐life measures carried out at four different time points (two pre‐treatment and two post‐treatment). The final assessment was at 3 months post‐intervention. Outcome & Results: Statistically significant improvement (p < 0.05) in oral intake methods (95% confidence interval (CI) = 4.70–5.50) and in pharyngeal residue from saliva (95% CI = 2.14–3.15) and solids (95% CI = 2.4–3.5) post‐intervention were confirmed using FEES with improvements at 3 months. The intervention protocol was well tolerated. Participants reported positive change in saliva control and duration of mealtimes as well as unanticipated improvements in voice and cognitive attention. Conclusions & Implications: An intensive neurorehabilitation with biofeedback shows positive effects in improving swallow function in IPD. This protocol is feasible with amendments to inform a larger clinical trial. What this paper adds: What is already known on the subject: Biofeedback has positive effects on increasing swallowing function and quality of life in people with IPD and dysphagia. sEMG is the most common method used to deliver swallowing biofeedback in this population. The quality of the evidence on the intervention, based on findings from a recent systematic review, is low. Included studies in this review were heterogeneous in terms of type and frequency of biofeedback, study design and outcome measures. The majority of outcome measures were subjective and higher quality studies to examine the efficacy of biofeedback using sEMG are needed. What this study adds: Recognizing the limitations of earlier studies, this within‐subject feasibility study examined the efficacy and effectiveness of an intensive biofeedback intervention using sEMG in a sample of people with dysphagia and IPD. Valid and reliable outcome measures were used and repeated after a 3‐month period. The feasibility of the methodological approach was also tested and a qualitative component was included in the study. Positive findings were evident. Qualitative information added new perspectives and provided direction for new outcomes to be included in future studies. This study helps to inform further research trials as well as clinical practice. Clinical implications of this study: This intensive intervention using principles of neuroplasticity and motor programming with sEMG biofeedback led not only to positive swallowing outcomes but also to unexpected benefits such as improved voice production and general attention skills. No adverse events were reported. Improvement in function was retained at 3 months post‐intervention. Despite the small sample size, participants described the benefits of the treatment, and enjoyed sEMG biofeedback tasks, especially using an sEMG game mode. This suggests that intensive biofeedback not only improved swallowing but also was acceptable to these participants. This intensive protocol has merit and is worth considering further in clinical practice. [ABSTRACT FROM AUTHOR]

Background: Understanding the natural history of developmental speech and language impairments can support the selection of children whose difficulties are persistent rather than transitory. It can also provide information against which the effectiveness of intervention can be evaluated. However, natural history data are difficult to collect ethically. Furthermore, as soon as an impairment is identified, the behaviour of those around changes, thus creating some level of intervention. Longitudinal cohort studies, where intervention is minimal, or the control arm of randomized trials have provided the best evidence. However, occasional opportunities arise where service waiting lists can provide data about the progress of children who have not received intervention. This natural history study arose within an ethnically diverse, community paediatric speech and language therapy service in the UK where levels of social disadvantage are high. Aims: To identify (1) the characteristics of the children who attended initial assessment and were selected for treatment; (2) the differences between children who did and did not attend reassessment; and (3) the factors associated with outcomes. Methods & Procedures: A cohort of 545 children were referred and assessed as in need of therapy. Due to resource constraints, intervention was not available for an average of 12 months. Children were invited to attend for a reassessment of need. Initial and follow‐up assessments were conducted by experienced clinicians using service guidelines and the Therapy Outcomes Measures Impairment Scale (TOM‐I). Descriptive and multivariate regression analyses examined child outcomes for changes in communication impairment, demographic factors and length of wait. Outcomes & Results: At initial assessment, 55% of children presented with severe and profound communication impairments. Children offered appointments at clinics in areas of high social disadvantage were less likely to attend reassessment. By reassessment, 54% of children showed spontaneous improvement (mean TOM‐I rating change = 0.58). However, 83% were still judged to require therapy. Approximately 20% of children changed their diagnostic category. Age and impairment severity at initial assessment were the best predictors of continuing requirement for input. Conclusions & Implications: Although children do make spontaneous progress post‐assessment and without intervention, it is likely that the majority will continue to be assigned case status by a Speech and Language Therapist. However, when evaluating the effectiveness of interventions, clinicians need to factor in the progress that a proportion of the caseload will make spontaneously. Services should be mindful that a lengthy wait may disproportionately impact children who already face health and educational inequalities. What This Paper Adds: What is already known on the subject: Data from longitudinal cohorts (where intervention has been minimal) and the no treatment control arms of randomized controlled trials have provided the best evidence of the natural progression of speech and language impairments in children. These studies provide a varied rate of resolution and progress depending on the case definitions and measurements used. What this study adds to existing knowledge: Uniquely, this study has evaluated the natural history of a large cohort of children who had been waiting for treatment for up to 18 months. Data showed that, over a period of waiting for intervention, the majority of those identified as a case by a Speech and Language Therapist remained a case. Using the TOM, on average children in the cohort made just over half a rating point progress during their waiting period. What are the potential or actual clinical implications of this work?: The maintenance of treatment waiting lists is probably an unhelpful service strategy for two reasons: first, the case status of the majority of the children is unlikely to change whilst they await intervention and thus children and their families are subjected to further limbo waiting time; second, the dropout from the waiting list may disproportionately affect children who are offered appointments in clinics where there are higher levels of social disadvantage, thus exacerbating inequalities in the system. Currently, a suggested reasonable outcome of intervention is a 0.5 rating change in one domain of TOMs. Study findings suggest this is insufficiently stringent for a paediatric community clinic caseload. There is a need to evaluate spontaneous improvement which may occur in other TOM domains (i.e., Activity, Participation and Wellbeing) and to agree an appropriate change metric for a community paediatric caseload.
