Brief Report: Treating Stuttering in an Adult with Autism Spectrum Disorder / Shelley B. BRUNDAGE in Journal of Autism and Developmental Disorders, 43-2 (February 2013)
[article]
Titre : Brief Report: Treating Stuttering in an Adult with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Shelley B. BRUNDAGE, Auteur ; Cory J. WHELAN, Auteur ; Cathleen M. BURGESS, Auteur Année de publication : 2013 Article en page(s) : p.483-489 Langues : (Eng) Mots-clés : Stuttering Autism Disfluency Treatment Single subject design Index. décimale : PER Périodiques Résumé : Stuttering and autism can co-occur and when they do it presents a significant communication challenge. This study examined the effectiveness of a modified version of the fluency rules program (FRP; Runyan and Runyan, Stuttering and related disorders of fluency, in 2007) to reduce stuttering frequency in a man with autism spectrum disorder (ASD). The participant's percentage of stuttered words (%SW) was calculated during conversational interactions with multiple conversation partners both within and outside of the clinic treatment sessions. Visual inspection methods revealed a reduction in %SW from an average of 14.5 %SW during baseline to 2.07 %SW during the withdrawal phase. The mean baseline reduction in %SW from baseline to the second treatment phase was 91.8 %. The FRP holds promise for reducing %SW in persons with ASD who stutter.

Titre : Neurodevelopment for syntactic processing distinguishes childhood stuttering recovery versus persistence Type de document : Texte imprimé et/ou numérique Auteurs : E. USLER, Auteur ; C. WEBER-FOX, Auteur Article en page(s) : p.4 Langues : Anglais (eng) Mots-clés : Children Event-related potentials Language development Language processing N400 P600 Stuttering Index. décimale : PER Périodiques Résumé : BACKGROUND: Characterized by the presence of involuntary speech disfluencies, developmental stuttering is a neurodevelopmental disorder of atypical speech-motor coordination. Although the etiology of stuttering is multifactorial, language development during early childhood may influence both the onset of the disorder and the likelihood of recovery. The purpose of this study was to determine whether differences in neural indices mediating language processing are associated with persistence or recovery in school-age children who stutter. METHODS: Event-related brain potentials (ERPs) were obtained from 31 6-7-year-olds, including nine children who do not stutter (CWNS), 11 children who had recovered from stuttering (CWS-Rec), and 11 children who persisted in stuttering (CWS-Per), matched for age, and all with similar socioeconomic status, nonverbal intelligence, and language ability. We examined ERPs elicited by semantic and syntactic (phrase structure) violations within an auditory narrative consisting of English and Jabberwocky sentences. In Jabberwocky sentences, content words were replaced with pseudowords to limit semantic context. A mixed effects repeated measures analysis of variance (ANOVA) was computed for ERP components with four within-subject factors, including condition, hemisphere, anterior/posterior distribution, and laterality. RESULTS: During the comprehension of English sentences, ERP activity mediating semantic and syntactic (phrase structure) processing did not distinguish CWS-Per, CWS-Rec, and CWNS. Semantic violations elicited a qualitatively similar N400 component across groups. Phrase structure violations within English sentences also elicited a similar P600 component in all groups. However, identical phrase structure violations within Jabberwocky sentences elicited a P600 in CWNS and CWS-Rec, but an N400-like effect in CWS-Per. CONCLUSIONS: The distinguishing neural patterns mediating syntactic, but not semantic, processing provide evidence that specific brain functions for some aspects of language processing may be associated with stuttering persistence. Unlike CWS-Rec and CWNS, the lack of semantic context in Jabberwocky sentences seemed to affect the syntactic processing strategies of CWS-Per, resulting in the elicitation of semantically based N400-like activity during syntactic (phrase structure) violations. This vulnerability suggests neural mechanisms associated with the processing of syntactic structure may be less mature in 6-7-year-old children whose stuttering persisted compared to their fluent or recovered peers.

Titre : Speech motor planning and execution deficits in early childhood stuttering Type de document : Texte imprimé et/ou numérique Auteurs : B. WALSH, Auteur ; K. M. METTEL, Auteur ; A. SMITH, Auteur Article en page(s) : p.27 Langues : Anglais (eng) Mots-clés : Preschool children Sex differences Speech kinematics Speech motor control Speech production Stuttering Index. décimale : PER Périodiques Résumé : BACKGROUND: Five to eight percent of preschool children develop stuttering, a speech disorder with clearly observable, hallmark symptoms: sound repetitions, prolongations, and blocks. While the speech motor processes underlying stuttering have been widely documented in adults, few studies to date have assessed the speech motor dynamics of stuttering near its onset. We assessed fundamental characteristics of speech movements in preschool children who stutter and their fluent peers to determine if atypical speech motor characteristics described for adults are early features of the disorder or arise later in the development of chronic stuttering. METHODS: Orofacial movement data were recorded from 58 children who stutter and 43 children who do not stutter aged 4;0 to 5;11 (years; months) in a sentence production task. For single speech movements and multiple speech movement sequences, we computed displacement amplitude, velocity, and duration. For the phrase level movement sequence, we computed an index of articulation coordination consistency for repeated productions of the sentence. RESULTS: Boys who stutter, but not girls, produced speech with reduced amplitudes and velocities of articulatory movement. All children produced speech with similar durations. Boys, particularly the boys who stuttered, had more variable patterns of articulatory coordination compared to girls. CONCLUSIONS: This study is the first to demonstrate sex-specific differences in speech motor control processes between preschool boys and girls who are stuttering. The sex-specific lag in speech motor development in many boys who stutter likely has significant implications for the dramatically different recovery rates between male and female preschoolers who stutter. Further, our findings document that atypical speech motor development is an early feature of stuttering.
