Relation of Speech-Language Profile and Communication Modality to Participation of Children With Cerebral Palsy.

PURPOSE: This study aimed to examine the contribution of speech motor impairment (SMI), language impairment, and communication modality to communicative and overall participation outcomes in school-age children with cerebral palsy (CP). METHOD: Eighty-one caregivers of children with CP provided information about their child's speech and language skills, communication modality, and participation through a web-based survey. Caregiver responses to two validated scales were used to quantify children's communicative participation and overall participation. Children were classified into four speech-language profile groups and three communication modality groups for comparison, based on caregiver-reported information regarding their child's communication skills. RESULTS: Children with CP who had co-occurring SMI and language impairment had significantly lower levels of communicative participation and involvement in activities overall, compared to children with SMI alone. Among children with SMI, augmentative and alternative communication (AAC) use was associated with greater overall frequency of participation and involvement in life activities. CONCLUSION: Children with CP who have both SMI and language impairment and those who are nonspeaking communicators should be prioritized early for communication interventions focused on maximizing participation, including consideration of AAC.

Identification of a know-do gap: An observational study of the assessment and treatment of dysphagia during inpatient stroke rehabilitation in primary healthcare in Norway.

PURPOSE: Oropharyngeal dysphagia is a common swallowing impairment post-stroke managed by speech language pathologists (SLP). This article aims to demonstrate a local know-do gap assessment for usual dysphagia care for patients undergoing inpatient stroke rehabilitation in primary healthcare in Norway, which included an assessment of the functional level of the patients and characteristics and outcomes of treatment. MATERIALS AND METHODS: In this observational study, we assessed the outcomes and interventions of patients admitted to inpatient rehabilitation following stroke. The patients received usual care from SLPs while the research team administered a dysphagia assessment protocol that included assessment of several swallowing domains including oral intake, swallowing, patient self-reported functional health status and health-related quality of life, and oral health. The treating SLPs documented the treatments provided in a treatment diary. RESULTS: Of 91 patients who consented, 27 were referred for SLP and 14 received treatment. During the median treatment period of 31.5 days (IQR = 8.8-57.0), patients received 7.0 treatment sessions (IQR = 3.8-13.5) of 60 minutes (IQR = 55-60). The patients who received SLP treatment demonstrated no/minor disorders (n = 7) and moderate/severe disorders (n = 7). Dysphagia treatments primarily included oromotor training and advice on bolus modification and were provided without association to dysphagia severity. Patients with moderate/severe swallowing impairments received slightly more SLP sessions over a longer time. CONCLUSIONS: This study identified gaps between current and best practices and opportunities to improve assessment, decision-making, and implement evidence-based practices.

A large-scale comparison of two voice synthesis techniques on intelligibility, naturalness, preferences, and attitudes toward voices banked by individuals with amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) commonly results in the inability to produce natural speech, making speech-generating devices (SGDs) important. Historically, synthetic voices generated by SGDs were neither unique, nor age- or dialect-appropriate, which depersonalized SGD use. Voices generated by SGDs can now be customized via voice banking and should ideally sound uniquely like the individual's natural speech, be intelligible, and elicit positive reactions from communication partners. This large-scale 2 x 2 mixed between- and within-participants design examined perceptions of 831 adult listeners regarding custom synthetic voices created for two individuals diagnosed with ALS via two synthesis systems in common clinical use (waveform concatenation and statistical parametric synthesis). The study explored relationships among synthesis system, dysarthria severity, synthetic speech intelligibility, naturalness, and preferences, and also provided a preliminary examination of attitudes regarding the custom synthetic voices. Synthetic voices generated via statistical parametric synthesis trained on deep neural networks were more intelligible, natural, and preferred than voices produced via waveform concatenation, and were associated with more positive attitudes. The custom synthetic voice created from moderately dysarthric speech was more intelligible than the voice created from mildly dysarthric speech. Clinical implications and factors that may have contributed to the relative intelligibilities are discussed.

Systematic Review of Variables Related to Instruction in Augmentative and Alternative Communication Implementation: Group and Single-Case Design.

PURPOSE: This article provides a systematic review and analysis of group and single-case studies addressing augmentative and alternative communication (AAC) intervention with school-aged persons having autism spectrum disorder (ASD) and/or intellectual/developmental disabilities resulting in complex communication needs (CCNs). Specifically, we examined participant characteristics in group-design studies reporting AAC intervention outcomes and how these compared to those reported in single-case experimental designs (SCEDs). In addition, we compared the status of intervention features reported in group and SCED studies with respect to instructional strategies utilized. PARTICIPANTS: Participants included school-aged individuals with CCNs who also experienced ASD or ASD with an intellectual delay who utilized aided or unaided AAC. METHOD: A systematic review using descriptive statistics and effect sizes was implemented. RESULTS: Findings revealed that participant features such as race, ethnicity, and home language continue to be underreported in both SCED and group-design studies. Participants in SCED investigations more frequently used multiple communication modes when compared to participants in group studies. The status of pivotal skills such as imitation was sparsely reported in both types of studies. With respect to instructional features, group-design studies were more apt to utilize clinical rather than educational or home settings when compared with SCED studies. In addition, SCED studies were more apt to utilize instructional methods that closely adhered to instructional features more typically characterized as being associated with behavioral approaches. CONCLUSION: The authors discuss future research needs, practice implications, and a more detailed specification of treatment intensity parameters for future research.

The effect of responsiveness to speech-generating device input on spoken language in children with autism spectrum disorder who are minimally verbal†.

The use of speech-generating devices (SGD) in early interventions for children with autism spectrum disorder (ASD) can improve communication and spoken language outcomes. The purpose of this study was to describe children's responsiveness to SGD input modeled by a social partner during adult-child play interactions over a 24-week intervention trial and explore the effect of that responsiveness on spoken language growth. This secondary analysis consisted of 31 children with less than 20 functional words at study entry who received a blended behavioral intervention (JASPER + EMT) as part of a randomized controlled trial. Significant improvements were seen in rate of responsiveness to both adult SGD models and adult natural speech models; only rate of responsiveness to SGD models at entry was a significant predictor of frequency of commenting and was a more robust predictor of number of different words post-intervention. Lastly, at entry, children with more joint attention and language responded to SGD models at significantly higher rates. Attention and responsiveness to SGD output may be important mechanisms of language growth and children who have more joint attention skills may particularly benefit from use of an SGD.

Falls in Patients With Communication Disability Secondary to Stroke.

Patients with stroke are at high risk of falls during inpatient rehabilitation admission. Communication disability is common following stroke; however, this population is often excluded from falls research. This study aimed to examine the falls of patients with communication disability following stroke, including the circumstances, contributing factors, and outcomes of the fall. This medical record review used the Generic Reference Model of patient safety as the analytical lens and data were analyzed descriptively. The study included 109 patients who experienced 308 falls. The most common type of fall was an "unwitnessed roll from bed." Patient factors contributed to half of all falls, injuries occurred in 15% of falls, and impacts to the hospital system included additional costs and staffing. Understanding the reasons why patients are attempting to get out of bed may identify ways to reduce the risk and incidence of falls in this population.

Is language ability associated with behaviors of concern in autism? A systematic review.

This review systematically synthesized evidence on the association between structural language ability and behaviors of concern (BoC) in autism. Four databases were searched for studies that included >10 autistic participants, measures of structural language (content and/or form of language) and BoC, and an analysis of their association. BoCs included self-injurious behavior (SIB), aggression, tantrums, and externalizing behavior. Methodological quality of studies were assessed using the Newcastle Ottawa Scale. Forty-five publications (n = 11,961) were included. Forty studies were cross-sectional and five were prospective cohort studies. Over 70% of the studies investigating expressive language and SIB (n = 10), aggression (n = 5), tantrums (n = 3), and externalizing behavior (n = 17) reported an inverse association, where lower expressive language ability was associated with increased BoC. Eleven out of sixteen studies of combined expressive and receptive language reported an inverse relationship with SIB or aggression. All outcomes were rated as moderate to very low certainty of evidence. This review highlights evidence showing an inverse association between expressive or combined language ability and SIB, and externalizing behavior in autism. However, further high-quality studies that use standardized, consistent measures of language and behavior and investigate longitudinal associations are needed. Early detection and support for reduced structural language difficulties have substantial potential to assist in reducing BoC.

Profiles of Children With Cortical Visual Impairment Who Use Augmentative and Alternative Communication: A Retrospective Examination.

PURPOSE: Cortical visual impairment (CVI) is the most common cause of visual impairment in children today and can impact the outcomes of children who rely on augmentative and alternative communication (AAC). This study provides baseline data of 13 children with CVI who used AAC during their first year of participation in an integrated CVI program. One purpose was to describe similarities and differences in the student's demographic, functional vision, communication, and educational profiles. A second purpose was to examine differences in students described with different communicator profiles. METHOD: Archived student records were de-identified and reviewed using a systematic coding scheme. Two researchers independently reviewed and coded all student records. Reliability was established. Measures included CVI Range scores; supports for positioning, mobility, vision, and writing; AAC systems, including modes, access methods, and language representation; communicative competence; self-determination; literacy; and mathematics. RESULTS: The study yielded a rich description of similarities and differences among students at baseline and led to careful consideration of differences among the participants with emergent communicator and context-dependent communicator profiles. CONCLUSIONS: Currently, limited evidence exists that informs practice regarding AAC assessment and intervention for children with CVI. This article describes a small sample of children with CVI who use AAC. Results underscore the need for educators and practitioners to ensure that vision functioning in students with CVI is evaluated carefully and regularly when conducting AAC assessment and intervention and formulating communication or education goals.

The effect of cue type on directive-following in children with moderate to severe autism spectrum disorder.

For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more accurately with the video clip than with spoken cues only, and significantly more accurately with spoken cues only relative to the sequence of graphic symbols. Results suggest that the short video clip along with spoken cues may be an optimal mode for enhancing learners' ability to follow directives containing prepositions. In addition, results reveal three statistically significant correlations between participants' preexisting skills and directive-following accuracy: a positive correlation between spoken preposition preassessment total score and accuracy in the spoken-alone condition; a positive correlation between spoken noun preassessment total score and accuracy in the video-clip condition; and a positive correlation between ASD severity and the need for repetition in the video-clip condition. Results also suggested that, for children with more severe ASD symptoms, the video clips require repetitions so that the relationships illustrated within it can gain more semantic salience. Implications for clinical practice and future research are discussed.

A Randomized Controlled Trial of an Intelligent Robotic Response to Joint Attention Intervention System.

Although there has been growing interest in utilizing robots for intervention in autism spectrum disorder (ASD), there have been very few controlled trials to assess the actual impacts of such systems on social communication vulnerabilities. This study reports a randomized controlled trial to investigate a robot-mediated response to joint attention intervention in a small (23 recruited; 20 completed) group of young children (average age = 2.54 years) with ASD. Small and nonsignificant group differences were observed regarding improvements in response to joint attention skills within and beyond the intervention. The sample showed tremendous individual variability in response to the system. Results highlight the current challenges related to developing pragmatic, beneficial, and generalizable robotic intervention systems for the targeted population.

Toddlers to teenagers: Long-term follow-up study of outcomes in autism spectrum disorder.

This prospective study examined the developmental changes over time of adolescents diagnosed in toddlerhood with autism spectrum disorder and searched for child characteristics at toddlerhood that predict outcome at adolescence. The study included 65 participants who were divided into low cognitive (developmental quotient < 85; N = 41) and high cognitive (developmental quotient ⩾ 85; N = 21) groups in adolescence. Participants underwent a comprehensive assessment of cognitive ability, adaptive skills, and autism severity. Significant differences in the current clinical phenotypes and in developmental changes over time were found between the two cognitive groups. At baseline, the high cognitive group had significantly less severe social communication deficits. Only the high cognitive group showed a decrease in social communication deficits over time. Although the two groups did not differ in their adaptive skills at the time of diagnosis, the high cognitive group had better adaptive skills at adolescence. Better adaptive communication skills in toddlerhood were associated with better outcome at adolescence in cognitive ability, adaptive skills, and fewer autism symptoms. Less impaired baseline social affect and better cognitive ability predicted higher cognitive level and adaptive skills at adolescence. Cognitive potential of individuals with autism spectrum disorder plays an important role in long-term outcome and comprehensive evaluations at toddlerhood have strong prognostic value in adolescence.

Care Management for Youth With Comorbid Developmental and Mental Health Conditions: A Discrete Choice Experiment Pilot Study.

OBJECTIVE: Caregivers of a child with a coexisting cognitive/intellectual and an emotional/behavior/developmental disability have difficult decisions regarding care management options for their child. This study aimed to pilot and refine an instrument to elicit caregivers' preferences in managing their child's care needs. METHODS: Subjects were 38 caregivers of a child aged 21 and younger with a coexisting cognitive/intellectual and an emotional/behavior/developmental disability. A mixed-methods design was used to develop and pilot a discrete choice experiment (DCE) to elicit care management preferences for their child. Six attributes of care management decisions were tested in the DCE: medication use, parental custody, time cost, social interactions, medication effects, and school placement. Subjects completed a paper-and-pencil survey after which a debriefing discussion was held to obtain feedback that would aid in refining the attribute descriptions. Conditional logistic regression generated mean scores for each attribute. Comments from the debriefing sessions were audio-recorded and used to modify the attribute descriptions. RESULTS: The majority (84%) of subjects were aged 40 years or older and a female caregiver. Common diagnoses of the children were autism spectrum disorder (55%) and attention-deficit/hyperactivity disorder (76%). Subjects preferred using fewer medications and maintaining decision-making authority as opposed to delegating authority to a third party. Medication effects on the child's mood were more important than effects on personality or body weight. CONCLUSIONS: The DCE was sensitive to caregivers' preferences for managing their child's coexisting cognitive/intellectual and emotional/behavior/developmental disability. Findings may help providers gauge treatment in a broader context of health outcomes.

A Deterioration in Hearing Is Associated With Functional and Cognitive Impairments, Difficulty With Communication, and Greater Health Instability.

Objectives: To examine the relationship between hearing deterioration and several health-related outcomes among home care clients in Ontario. Design: Longitudinal analysis was completed for clients with at least two comprehensive assessments. Hearing status, based on a single item, ranged from zero (no impairment) to three (highly impaired). Hearing deterioration was defined as at least a 1-point decline between subsequent assessments. Results: Seven percent experienced a 1-point deterioration in hearing and roughly 1% had a 2/3-point decline. After adjusting for other covariates, increasing age (odds ratio = 1.94; 95% confidence intervals [CIs] = [1.45, 2.61]) and a diagnosis of Alzheimer's disease (1.37; CI = [1.04, 1.80]) and other dementias (1.32; CI = [1.07, 1.63]) increased the risk of a 2/3-point deterioration. Conclusion: These findings can assist home care professionals and policy makers in creating and refining interventions to meet the needs of older adults with hearing difficulties.

Validation of Pain Assessment Checklist for Seniors with Limited Ability to Communicate-II (PACSLAC-II) in Iranian older adults with dementia living in nursing homes.

BACKGROUND: Some dementia patients can self-report pain although the reports are not valid in severe dementia. Observational scales have been developed for pain assessment in these patients. This study aimed to assess the psychometric properties of the Persian version of Pain Assessment Checklist for Seniors with Limited Ability to Communicate-II (PACSLAC-II). METHODS: This validation study was conducted on 138 older adults with dementia suffering from chronic pain who lived in nursing homes. The PACSLAC-II Persian version was applied through observations during activity and rest. Reliability of the PACSLAC-II was evaluated by Cronbach's alpha and intra-class correlation coefficients. Construct validity was determined by confirmatory factor analysis, divergent and convergent validity. The Spearman's rank correlation between PACSLAC-II scores and Faces Pain Scale was calculated for concurrent validity. Known-group validity during activity and rest was calculated by Wilcoxon signed ranks test. RESULTS: Cronbach's alpha coefficient for facial expression (0.82), verbalisation (0.72), and body movement (0.84) subscales indicated good internal consistency. The intra-class correlation coefficients between two raters was 0.76 and in three times evaluation, the value was 0.76. Convergent validity with Iranian Brief Pain Inventory and divergent validity with 15-item Geriatric Depression Scale confirmed the construct validity of PACSLAC-II. Three factors structure of PACSLAC-II was approved, and most of the variance was explained by facial expressions. The PACSLAC-II can discriminate between pain and non-pain events and has a moderate correlation with Faces Pain Scale (r = 0.33). CONCLUSIONS: PACSLAC-II Persian version is a valid and reliable scale for pain assessment in older adults with dementia.

Correlation between biomarkers of pain in saliva and PAINAD scale in elderly people with cognitive impairment and inability to communicate: descriptive study protocol.

INTRODUCTION: Pain is an under-diagnosed problem in elderly people, especially in those with cognitive impairment who are unable to verbalise their pain. Although the Pain assessment in advanced dementia scale (PAINAD) scale is a tool recognised for its clinical interest in this type of patients, its correlation with the saliva biomarkers reinforced its utility. The aim of this research will be to correlate the scores of this scale with the levels of biomarkers of pain found in saliva samples of patients with cognitive impairment and inability to communicate. METHODS AND ANALYSIS: This is an observational study. The level of pain will be evaluated using the PAINAD scale. Moreover, pain biomarkers, in particular secretory IgA and soluble tumour necrosis factor receptor type II, will be determined in saliva. Both assessments will be conducted in 75 patients aged over 65 years with advanced cognitive impairment and inability to communicate. The PAINAD scores will be correlated with the levels of these biomarkers of pain. A control group consisting of 75 healthy subjects aged over 65 years will be included in the study. Moreover, sociodemographic variables and variables related to pain, dementia and other clinical conditions will be recorded. The analysis will be performed with the statistical package SPSS V.22 and the software R. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the Andalusian Human Research Ethics Committee. In addition, this study has been financed by the Junta de Andalucía through a regional health research fund (Research code: PI-0357-2017). The results will be actively disseminated trough a high-impact journal in our study area, conference presentations and social media.

Effects of an iPad-based Speech-Generating Device Infused into Instruction with the Picture Exchange Communication System for Adolescents and Young Adults with Severe Autism Spectrum Disorder.

This study used a multiple baseline, single-subject research design to investigate the efficacy of an iPad®-based speech-generating device (SGD). The iPad was equipped with the SPEAKall!® application to function as a SGD. SGDs are a form of aided augmentative and alternative communication (AAC) allowing a user to communicate using digitized and/or synthesized speech. Instruction followed a modified version of the intervention phases from the Picture Exchange Communication System (PECS). This modified PECS protocol was implemented with two adolescents and one young adult between the ages of 14 and 23. All three participants were diagnosed with severe autism spectrum disorder and little to no functional speech. Dependent measures included the ability to request for edible and tangible items as the primary measure, and the ability to engage in natural speech production as an ancillary measure to determine simultaneous, additive effects on speech acquisition. Results indicated increases in requesting behaviors for all three participants across intervention and maintenance phases. Once participants mastered requesting of edible items, they were able to generalize the skill to tangible items. However, mixed results were found when targeting natural speech production. Based on the current findings, the infusion of an iPad-based SGD into PECS instruction may be effective in increasing initial requesting skills; however, a facilitative effect on increasing speech acquisition cannot necessarily be expected for every participant.

Expression Recognition Difficulty Is Associated with Social But Not Attention-to-Detail Autistic Traits and Reflects Both Alexithymia and Perceptual Difficulty.

Autistic people often show difficulty with facial expression recognition. However, the degree of difficulty varies widely, which might reflect varying symptom profiles. We examined three domains of autistic traits in the typical population and found that more autistic-like social skills were associated with greater difficulty labelling expressions, and more autistic-like communication was associated with greater difficulty labelling and perceptually discriminating between expressions. There were no associations with autistic-like attention to detail. We also found that labelling, but not perceptual, difficulty was mediated by alexithymia. We found no evidence that labelling or perceptual difficulty was mediated by weakened adaptive coding. Results suggest expression recognition varies between the sub-clinical expressions of autistic symptom domains and reflects both co-occurring alexithymia and perceptual difficulty.

A Systematic Review of Interventions to Promote Varied Social-Communication Behavior in Individuals With Autism Spectrum Disorder.

Individuals with autism spectrum disorder (ASD) may engage in repetitive social-communication behaviors that can limit their skill acquisition, access to reinforcement, and access to less restrictive settings. Basic and applied research indicates that variability, or the extent to which responses are topographically different from one another, is influenced by antecedent and consequence interventions. Our purpose in this study is to systematically review the literature on interventions to increase variable social-communication behaviors in individuals with ASD. We identified 32 studies through a database search and screened them using the What Works Clearinghouse (WWC) Single-Case Design Standards. Eighteen studies containing 55 cases met WWC Design Standards. We coded the descriptive characteristics and strength of evidence based on visual analysis from each of these 18 studies and calculated effect sizes using Tau-U. Our results indicate that most cases (65%) provide strong evidence of a functional relation between the interventions and varied social-communication behaviors, and the median Tau-U was .82. We discuss the implications of our results for practice and for future research on interventions designed to increase variability with this population.

An Evaluation of the Effects of Varying Magnitudes of Reinforcement on Variable Responding Exhibited by Individuals With Autism.

Interventions aimed at increasing communicative response variability hold particular importance for individuals with autism spectrum disorders (ASD). Several procedures have been demonstrated in the applied and translational literature to increase response variability. However, little is known about the relationship between reinforcer magnitude and response variability. In the basic literature, Doughty, Giorno, and Miller evaluated the effects of reinforcer magnitude on behavioral variability by manipulating reinforcer magnitude across alternating relative frequency threshold contingencies, with results suggesting that larger reinforcers induced repetitive responding. The purpose of this study was to translate Doughty et al.'s findings to evaluate the relative effects of different magnitudes of reinforcement on communicative response variability in children with ASD. A Lag 1 schedule of reinforcement was in place during each condition within an alternating treatments design. Magnitudes of reinforcement contingent on variable communicative responding were manipulated across the two conditions. Inconsistent with basic findings, the results showed higher levels of variable communicative responding associated with the larger magnitude of reinforcement. These outcomes may have potential implications for interventions aimed at increasing response variability in individuals with ASD, as well as future research in this area.
