Index. décimale : PER Périodiques Résumé : This systematic review examined definitions of "nonverbal" or "minimally verbal" and assessment measures used to evaluate communication in intervention studies focusing on improving expressive verbal communication in children with autism spectrum disorder (ASD). We reviewed sample size, number of participants, participant age, and male/female representation. Our analysis yielded relatively few studies with non/minimally verbal children with ASD focusing on verbal expressive communication. Further, we found large inconsistencies in measures used, definitions of "nonverbal" and "minimally verbal", and ages targeted. Guidelines are suggested to create a more uniform assessment protocol with systematic descriptions of early communication learners as a foundational step for understanding the heterogeneity in this group and replicating research findings for this subgroup of children with ASD.

Delayed M50/M100 evoked response component latency in minimally verbal/nonverbal children who have autism spectrum disorder / Timothy P.L. ROBERTS in Molecular Autism, 10 (2019)  

Public ISBD [article]  inMolecular Autism > 10 (2019) . - 34 p. Titre : Delayed M50/M100 evoked response component latency in minimally verbal/nonverbal children who have autism spectrum disorder Type de document : texte imprimé Auteurs : Timothy P.L.

Langues : Anglais (eng) Mots-clés : Auditory cortex  Autism spectrum disorder  M50/M100 responses and language impairment  Magnetoencephalography  Minimally verbal/non-verbal children  Nonverbal Index. décimale : PER Périodiques Résumé : Abnormal auditory neuromagnetic M50 and M100 responses, reflecting primary/secondary auditory cortex processing, have been reported in children who have autism spectrum disorder (ASD). Some studies have reported an association between delays in these responses and language impairment. However, as most prior research has focused on verbal individuals with ASD without cognitive impairment, rather little is known about neural activity during auditory processing in minimally verbal or nonverbal children who have ASD (ASD-MVNV)-children with little or no speech and often significant cognitive impairment. To understand the neurophysiological mechanisms underlying auditory processing in ASD-MVNV children, magnetoencephalography (MEG) measured M50 and M100 responses arising from left and right superior temporal gyri during tone stimuli in three cohorts: (1) MVNV children who have ASD (ASD-MVNV), (2) verbal children who have ASD and no intellectual disability (ASD-V), and (3) typically developing (TD) children. One hundred and five participants (8-12 years) were included in the final analyses (ASD-MVNV: n = 16, 9.85 +/- 1.32 years; ASD-V: n = 55, 10.64 +/- 1.31 years; TD: n = 34, 10.18 +/- 1.36 years). ASD-MVNV children showed significantly delayed M50 and M100 latencies compared to TD. These delays tended to be greater than the corresponding delays in verbal children with ASD. Across cohorts, delayed latencies were associated with language and communication skills, assessed by the Vineland Adaptive Behavior Scale Communication Domain. Findings suggest that auditory cortex neural activity measures could be dimensional objective indices of language impairment in ASD for either diagnostic (e.g., via threshold or cutoff) or prognostic (considering the continuous variable) use.

Improving Pragmatics in Nonverbal Children with Autism Using Melodic Based Communication Therapy / Givona A. SANDIFORD in Autism - Open Access, 3-3 (December 2013)  

Public ISBD [article]  inAutism - Open Access > 3-3 (December 2013) . - 5 p. Titre : Improving Pragmatics in Nonverbal Children with Autism Using Melodic Based Communication Therapy Type de document : texte imprimé Auteurs : Givona A. SANDIFORD, Auteur ; Karen J. MAINESS, Auteur ; Noha S. DAHER, Auteur Année de publication : 2013 Article en page(s) : 5 p. Langues : Anglais (eng) Mots-clés : Autism  Pragmatics  Social skills  Music  Speech therapy  Nonverbal Index. décimale : PER Périodiques Résumé : Background of study: Persistent deficits in social communication and social interaction are key components in the diagnosis of autism. For this reason it is clear that successful intervention for individuals with autism must address this deficit. Melodic Based Communication Therapy (M.B.C.T) has been previously found to improve expressive vocabulary and verbal imitative abilities in nonverbal individuals with autism over the age of 5; however findings on the effect of M.B.C.T. on pragmatic (social) language have not previously been discussed. Purpose: The objective of this study was to examine the effect of 5 consecutive weeks of Melodic Based Communication Therapy on pragmatics in nonverbal children with autism. Method: Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned to the M.B.C.T. or control group. Participants received 5 weeks of intervention, with four 45-minute individual sessions a week. The Pragmatic Language Skills Inventory (PLSI) was used to measure pragmatics pre and post treatment. Results: Following treatment, the M.B.C.T. group showed significant improvement in PLSI score (72.3 ± 10.1 vs 65.4 ± 7.0, p=.04) while the control group did not (67.7 ± 1.2 vs 66.8 ±.5, p=.32). However, there was no significant difference in improvement between the two groups (6.9 ± 2.4 vs 1.0 ±.5, p=.11). Conclusions: Results suggest M.B.C.T. may be a viable means of improving pragmatics in children with autism over time. However, a larger sample size may be needed for more conclusive results.

MEG-PLAN: a clinical and technical protocol for obtaining magnetoencephalography data in minimally verbal or nonverbal children who have autism spectrum disorder / Emily S. KUSCHNER in Journal of Neurodevelopmental Disorders, 13 (2021)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 13 (2021) Titre : MEG-PLAN: a clinical and technical protocol for obtaining magnetoencephalography data in minimally verbal or nonverbal children who have autism spectrum disorder Type de document : texte imprimé Auteurs : Emily S. KUSCHNER, Auteur ; Mina KIM, Auteur ; Luke BLOY, Auteur ; Marissa DIPIERO, Auteur ; J. Christopher EDGAR, Auteur ; Timothy P.L. ROBERTS, Auteur Langues : Anglais (eng) Mots-clés : Aptitude  Autism Spectrum Disorder  Child  Female  Humans  Language  Magnetoencephalography  Male  Neuroimaging  Applied behavior analysis  Autism spectrum disorder  Compliance  Imaging methodology  Intellectual disability  Minimally verbal  Nonverbal  Imaging, AveXis, Spago Nanomedicine, and Acadia Pharmaceuticals. TR and JCE  disclose IP related to the use of MEG as a biomarker for ASD. No other authors  declare any financial disclosures. Index. décimale : PER Périodiques Résumé : BACKGROUND: Neuroimaging research on individuals who have autism spectrum disorder (ASD) has historically been limited primarily to those with age-appropriate cognitive and language performance. Children with limited abilities are frequently excluded from such neuroscience research given anticipated barriers like tolerating the loud sounds associated with magnetic resonance imaging and remaining still during data collection. To better understand brain function across the full range of ASD there is a need to (1) include individuals with limited cognitive and language performance in neuroimaging research (non-sedated, awake) and (2) improve data quality across the performance range. The purpose of this study was to develop, implement, and test the feasibility of a clinical/behavioral and technical protocol for obtaining magnetoencephalography (MEG) data. Participants were 38 children with ASD (8-12 years) meeting the study definition of minimally verbal/nonverbal language. MEG data were obtained during a passive pure-tone auditory task. RESULTS: Based on stakeholder feedback, the MEG Protocol for Low-language/cognitive Ability Neuroimaging (MEG-PLAN) was developed, integrating clinical/behavioral and technical components to be implemented by an interdisciplinary team (clinicians, behavior specialists, scientists, and technologists). Using MEG-PLAN, a 74% success rate was achieved for acquiring MEG data, with a 71% success rate for evaluable and analyzable data. Exploratory analyses suggested nonverbal IQ and adaptive skills were related to reaching the point of acquirable data. No differences in group characteristics were observed between those with acquirable versus evaluable/analyzable data. Examination of data quality (evaluable trial count) was acceptable. Moreover, results were reproducible, with high intraclass correlation coefficients for pure-tone auditory latency. CONCLUSIONS: Children who have ASD who are minimally verbal/nonverbal, and often have co-occurring cognitive impairments, can be effectively and comfortably supported to complete an electrophysiological exam that yields valid and reproducible results. MEG-PLAN is a protocol that can be disseminated and implemented across research teams and adapted across technologies and neurodevelopmental disorders to collect electrophysiology and neuroimaging data in previously understudied groups of individuals.

Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned to either treatment group. Both groups made significant progress after treatment. The MBCT group progressed significantly in number of verbal attempts after weeks 1 through 4 and number of correct words after weeks 1 and 3, while the traditional group progressed significantly after weeks 4 and 5. No significant differences in number of verbal attempts or number of correct words were noted between groups following treatment. A significant number of new words were heard in the home environment for the MBCT group (p = .04). Participants in the MBCT group had more imitative attempts (p = .03). MBCT appears to be a valid form of intervention for children with autism.
