OBJECTIVE: To descriptively compare and contrast intervention techniques for preschool children with features of developmental language disorder (outcome: oral vocabulary) and speech sound disorder (outcome: speech comprehensibility) and analyse them in relation to effectiveness and theory.
METHODS: This is a systematic review with narrative synthesis. The process was supported by an expert steering group consisting of relevant professionals and people with lived experience.
METHODS: Ovid Emcare, MEDLINE Complete, CINAHL, APA PsycINFO, ERIC, and Communication Source from January 2012 were searched. Relevant studies were obtained from an initial published review (up to January 2012).
METHODS: Interventions for preschool children (80% aged 2:0-5:11 years) with idiopathic speech or language needs; outcomes relating to either oral vocabulary or speech comprehensibility.
METHODS: Searches were conducted on 27 January 2023. Two independent researchers screened at abstract and full-text levels. Data regarding intervention content (eg, techniques) and format/delivery (eg, dosage, location) were extracted. Data were synthesised narratively according to the methods of Campbell et al.
RESULTS: 24 studies were included: 18 for oral vocabulary and 6 for speech comprehensibility. There were 11 randomised controlled trials, 2 cohort studies and 11 case series. Similarities included a focus on input-related techniques and similar therapy activities. Speech studies were more likely to be professional-led and clinic-led, rather than at home and through a parent. Analysis was restricted by heterogeneity in study design and terminology, as well as gaps within intervention reporting. Information deemed important to the expert steering group was missing.
CONCLUSIONS: Similarities and differences between intervention techniques for oral vocabulary and speech comprehensibility have been identified and synthesised. However, analysis of effectiveness was limited due to issues with study design and heterogeneity within studies. This has implications for the progression of the evidence base within the field.

In speech-language therapy, the evaluation of children with atypical speech embodies the practical expertise of the therapist and the therapeutic goal of facilitating rehabilitation by guiding these children toward more typical speech behaviors. This study aims to provide an interactional explanation of how positive evaluations given by speech therapists are sequentially formatted, constructed, and oriented in therapy practice and what interactional consequences they have on the interpretation and learning of children with hearing impairment. Adopting conversation analysis as a methodology, this empirical study delves into naturally occurring conversations between speech therapists and children with hearing impairment within the context of Chinese speech-language therapy, focusing specifically on instances of positive evaluations in the third-turn position. The analysis reveals a prevalent occurrence of positive evaluations during therapeutic interactions, showcasing a diverse range of formats employed, spanning from explicit to implicit expressions. A fine-grained conversation analysis demonstrates the delicate and intricate nature of therapists\' positive evaluations, in terms of their indexicality (the function of being referential), and sensitivity to local contingencies. Furthermore, these positive evaluations serve as a critical site for displaying the epistemic asymmetry and its negotiation in and through therapist-client interactions. By providing an empirical demonstration of the interactional skill involved in speech-language therapy and advocating for evaluations characterized by clear indexicality and recipient-orientedness, this study contributes to enhancing the efficiency and effectiveness of rehabilitation practices while shedding new light on the atypical interactions involving people with communicative impairments.

BACKGROUND: Children who are deaf or hard-of-hearing (DHH) are at risk for speech and language delay. Language outcomes are worse in DHH children from lower socioeconomic backgrounds, due in part to disparities in access to specialised speech-language therapy. Teletherapy may help improve access to this specialised care and close this language gap. Inclusion of diverse DHH children in prospective randomised clinical trials has been challenging but is necessary to address disparities and pursue hearing health equity. Stakeholder input regarding decisions on study design elements, including comparator groups, masking, assessments and compensation, is necessary to design inclusive studies. We have designed an inclusive, equitable comparativeness effectiveness trial to address disparities in paediatric hearing health. The specific aims of the study are to determine the effect of access to and utilisation of speech-language teletherapy in addressing language disparities in low-income children who are DHH.
METHODS: After stakeholder input and pilot data collection, we designed a randomised clinical trial and concurrent longitudinal cohort trial to be conducted at four tertiary children\'s hospitals in the USA. Participants will include 210 DHH children aged 0-27 months. 140 of these children will be from lower income households, who will be randomised 1:1 to receive usual care versus usual care plus access to supplemental speech-language teletherapy. 70 children from higher income households will be simultaneously recruited as a comparison cohort. Primary outcome measure will be the Preschool Language Scales Auditory Comprehension subscale standard score, with additional speech, language, hearing and quality of life validated measures as secondary outcomes.
BACKGROUND: This study was approved by the Institutional Review Boards of the participating sites: the University of California, San Francisco (19-28356), Rady Children\'s Hospital (804651) and Seattle Children\'s Hospital (STUDY00003750). Parents of enrolled children will provide written informed consent for their child\'s participation. Professional and parent stakeholder groups that have been involved throughout the study design will facilitate dissemination and implementation of study findings via publication and through national and regional organisations.

In this systematic review and meta-analysis, our aim was to identify and quantify evidence of action observation therapy (AOT) efficacy in managing language deficits in patients with aphasia. This study conducts two quantitative investigations: firstly, comparing the effects of AOT and conventional control therapy in different groups, and secondly, analyzing within AOT group to explore potential moderators of AOT effectiveness. Four databases were searched up until August 2023 to find studies utilizing AOT for aphasia management. Seven eligible studies were included. The main analyses revealed moderate evidence of improvement in naming tasks, with a large effect size (Hedge\'s g = 1.27, 95 %CI [0.44; 2.09], p = 0.003, I2 < 25) following AOT compared to control interventions. Furthermore, to be efficient, AOT should focus on human actions (e.g., running, jumping) rather than non-human actions (e.g., meowing or barking). These findings indicate that AOT is a promising alternative complementary approach for patients with aphasia. Future research should confirm the potential benefits of AOT with more randomized controlled studies and aim to clarify the minimal dose necessary and the possibility of transfer to various language tasks.

People with Parkinson\'s disease (PD) experience a range of progressive motor and non-motor symptoms, that negatively affect their daily functioning, social participation and quality of life. Allied health therapies have emerged as an effective treatment approach-complementary to pharmacological and neurosurgical treatments-which reduces the impact of PD in daily life. In this article, we propose criteria for what constitutes specialized allied health care for PD, and we review allied health research in PD in terms of meeting these criteria and its outcomes for monodisciplinary approaches as well as multi- or interdisciplinary allied health interventions. We focus on the three most studied allied health disciplines in PD: physical therapy, occupational therapy and speech-language therapy. Overall, the available evidence underscores the importance and potential benefits of specialized allied health care for people with PD. Our proposed criteria and recommendations for future research might help in further delineating specialized allied health care.

UNASSIGNED: This study examines the accuracy of Interaction Detection in Early Childhood Settings (IDEAS), a program that automatically transcribes audio files and estimates linguistic units relevant to speech-language therapy, including part-of-speech units that represent features of language complexity, such as adjectives and coordinating conjunctions.
UNASSIGNED: Forty-five video-recorded speech-language therapy sessions involving 27 speech-language pathologists (SLPs) and 56 children were used. The F measure determines the accuracy of IDEAS diarization (i.e., speech segmentation and speaker classification). Two additional evaluation metrics, namely, median absolute relative error and correlation, indicate the accuracy of IDEAS for the estimation of linguistic units as compared with two conditions, namely, Oracle (manual diarization) and Voice Type Classifier (existing diarizer with acceptable accuracy).
UNASSIGNED: The high F measure for SLP talk data suggests high accuracy of IDEAS diarization for SLP talk but less so for child talk. These differences are reflected in the accuracy of IDEAS linguistic unit estimates. IDEAS median absolute relative error and correlation values for nine of the 10 SLP linguistic unit estimates meet the accuracy criteria, but none of the child linguistic unit estimates meet these criteria. The type of linguistic units also affects IDEAS accuracy.
UNASSIGNED: IDEAS was tailored to educational settings to automatically convert audio recordings into text and to provide linguistic unit estimates in speech-language therapy sessions and classroom settings. Although not perfect, IDEAS is reliable in automatically capturing and returning linguistic units, especially in SLP talk, that are relevant in research and practice. The tool offers a way to automatically measure SLP talk in clinical settings, which will support research seeking to understand how SLP talk influences children\'s language growth.

UNASSIGNED: Treatment response is the degree to which an individual benefits from a treatment. This systematic review sought to identify and synthesize research evidence regarding individual characteristics that predict language treatment response among children with developmental language disorder (DLD).
UNASSIGNED: To be eligible for inclusion, articles needed to report results of an oral language treatment program in a group of children aged 4-10 years with identified DLD and also include a quantitative analysis of the relation between one or more pretreatment child characteristics and the outcome of language treatment. Seven databases (Cumulated Index to Nursing and Allied Health Literature, Dissertations and Theses Global, Education Resources Information Center, Linguistics and Language Behavior Abstracts, PsycINFO, Medline, and Web of Science) were searched for articles in June and July 2021, with search updates conducted in May 2023. Studies were categorized by the type of treatment provided, and results were synthesized qualitatively.
UNASSIGNED: The review included 31 studies, 1,551 participants with DLD, and over 300 statistical tests of a predictor\'s effect on language treatment response. Most studies (n = 21) included only monolingual speakers of English, with five studies including bilinguals and five including monolingual speakers of non-English languages. Language treatments targeted word learning in controlled or clinical conditions, grammatical learning in controlled or clinical conditions, or multiple language targets in clinical conditions. Predictors of treatment response are summarized across four categories: cognitive, demographic, pretreatment language levels, and other.
UNASSIGNED: There were relatively few significant tests of the predictors of language treatment response. A central limitation of the evidence is that most included studies were designed to consider language treatment efficacy, not predictors of treatment response. Increasing research attention to the question of predictors of language treatment response in children with DLD is needed to enhance treatment and optimize outcomes for individual children.

To assess the clinical effectiveness of two speech and language therapy approaches versus no speech and language therapy for dysarthria in people with Parkinson\'s disease.
Pragmatic, UK based, multicentre, three arm, parallel group, unblinded, randomised controlled trial.
The speech and language therapy interventions were delivered in outpatient or home settings between 26 September 2016 and 16 March 2020.
388 people with Parkinson\'s disease and dysarthria.
Participants were randomly assigned to one of three groups (1:1:1): 130 to Lee Silverman voice treatment (LSVT LOUD), 129 to NHS speech and language therapy, and 129 to no speech and language therapy. LSVT LOUD consisted of four, face-to-face or remote, 50 min sessions each week delivered over four weeks. Home based practice activities were set for up to 5-10 mins daily on treatment days and 15 mins twice daily on non-treatment days. Dosage for the NHS speech and language therapy was determined by the local therapist in response to the participants\' needs (estimated from prior research that NHS speech and language therapy participants would receive an average of one session per week over six to eight weeks). Local practices for NHS speech and language therapy were accepted, except for those within the LSVT LOUD protocol. Analyses were based on the intention to treat principle.
The primary outcome was total score at three months of self-reported voice handicap index.
People who received LSVT LOUD reported lower voice handicap index scores at three months after randomisation than those who did not receive speech and language therapy (-8.0 points (99% confidence interval -13.3 to -2.6); P<0.001). No evidence suggests a difference in voice handicap index scores between NHS speech and language therapy and no speech and language therapy (1.7 points (-3.8 to 7.1); P=0.43). Patients in the LSVT LOUD group also reported lower voice handicap index scores than did those randomised to NHS speech and language therapy (-9.6 points (-14.9 to -4.4); P<0.001). 93 adverse events (predominately vocal strain) were reported in the LSVT LOUD group, 46 in the NHS speech and language therapy group, and none in the no speech and language therapy group. No serious adverse events were recorded.
LSVT LOUD was more effective at reducing the participant reported impact of voice problems than was no speech and language therapy and NHS speech and language therapy. NHS speech and language therapy showed no evidence of benefit compared with no speech and language therapy.

The S3 Guideline on the Treatment of Language Development Disorders: Summary of Recommendations Abstract: The German S3 Guidelines on the Treatment of Developmental Speech and Language Disorders (AWMF: No. 049-015) were published on the AWMF homepage at the end of 2022. The German Society for Phoniatrics and Paedaudiologie coordinated the work and developed the guideline text together with linguists and speech and language therapists. Many scientific medical societies consented to the respective recommendations. For the first time in the German-speaking area, the guideline group reviewed international research results on the treatment of various speech and language disorders and formulated evidence- or consensus-based recommendations for clinical care. The present article summarizes these recommendations and evaluates the guidelines from the perspective of child and adolescent psychiatry and psychotherapy.
Zusammenfassung: Die S3-Leitlinie zur Therapie von Sprachentwicklungsstörungen (AWMF: Nr. 049-015), die Ende 2022 auf der Homepage der AWMF veröffentlich wurde, ist unter Federführung der Deutschen Gesellschaft für Phoniatrie und Pädaudiologie in Kooperation mit zahlreichen Sprachwissenschaftler_innen und Sprachtherapeut_innen entwickelt und von zahlreichen wissenschaftlichen medizinischen Fachgesellschaften konsentiert worden. Die Leitliniengruppe hat erstmalig für den deutschen Sprachraum versucht, die internationale Studienlage zur Therapie unterschiedlicher Sprach- und Sprechstörungen aufzuarbeiten und darauf basierend Evidenz- oder auch Konsensus-basierte Empfehlungen für die klinische Versorgung zu formulieren. In dem vorliegenden Artikel werden diese Empfehlungen zusammenfassend dargestellt, und es wird eine Wertung der Leitlinie aus Kinder- und Jugendpsychiatrischer Sicht vorgenommen.

UNASSIGNED: We investigated the efficacy of Story Champs for improving oral language in third-grade Spanish-English bilingual children with developmental language disorder (DLD).
UNASSIGNED: We implemented a concurrent multiple-baseline across-participants single-case design with four bilingual Spanish-English third-grade students with DLD. Treatment was carried out over 12 sessions with approximately two sessions per week. Maintenance sessions were conducted 1, 2, and 4 weeks postintervention. Participants were explicitly taught story grammar elements, causal and temporal connections, and modifiers within story retells and personal narratives. Dependent variables were story grammar, grammatical complexity, modifiers and listening comprehension within story retells, and story grammar and grammatical complexity within personal narratives. Outcome measures were assessed at the end of every baseline, intervention, and maintenance session using the Narrative Language Measures-Listening (NLM-L).
UNASSIGNED: Visual analyses for outcome measures suggested slight increases in scores on the NLM-L during intervention accompanied by marked variability. Within-case analyses of story retell performance suggested an intervention effect on story grammar for two participants and on grammatical complexity and modifier use for one participant. For personal narratives, within-case analyses of personal narrative performance suggested an intervention effect on story grammar for one participant.
UNASSIGNED: Overall, Story Champs demonstrated efficacy for improving story grammar use in story retells for three out of four participants. It did not show efficacy for improving grammatical complexity, modifier use, or listening comprehension within story retells, nor did it show efficacy for improving story grammar and grammatical complexity within personal narratives.
