Motor Memory Deficits Contribute to Motor Impairments in Autism Spectrum Disorder / K. A. NEELY in Journal of Autism and Developmental Disorders, 49-7 (July 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-7 (July 2019) . - p.2675-2684 Titre : Motor Memory Deficits Contribute to Motor Impairments in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : K.

MOSCONI, Auteur Article en page(s) : p.2675-2684 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Motor  Precision grip  Visual feedback  Working memory Index. décimale : PER Périodiques Résumé : Sensorimotor abnormalities are common in individuals with autism spectrum disorder (ASD); however, the processes underlying these deficits remain unclear. This study examined force production with and without visual feedback to determine if individuals with ASD can utilize internal representations to guide sustained force. Individuals with ASD showed a faster rate of force decay in the absence of visual feedback. Comparison of force output and tests of social and verbal abilities demonstrated a link between motor memory impairment and social and verbal deficits in individuals with ASD. This finding suggests that deficits in storage or retrieval of motor memories contribute to sensorimotor deficits and implicates frontoparietal networks involved in short-term consolidation of action dynamics used to optimize ongoing motor output.

IQ and Sensory Symptom Severity Best Predict Motor Ability in Children With and Without Autism Spectrum Disorder / Olivia J SURGENT in Journal of Autism and Developmental Disorders, 51-1 (January 2021)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 51-1 (January 2021) . - p.243-254 Titre : IQ and Sensory Symptom Severity Best Predict Motor Ability in Children With and Without Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Olivia J SURGENT, Auteur ; Matthew WALCZAK, Auteur ; Oskar ZARZYCKI, Auteur ; Karla K. AUSDERAU, Auteur ; Brittany G TRAVERS, Auteur Article en page(s) : p.243-254 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Cognition  Motor  Sensory Index. décimale : PER Périodiques Résumé : Motor challenges are commonly reported in autism spectrum disorder (ASD). Yet, there is substantial heterogeneity in motor ability within ASD, and it is unknown what behavioral characteristics best explain individual differences in motor ability in ASD and related conditions. This observational study examined motor ability as a function of sensory features, attention deficit/hyperactivity symptoms, ASD symptoms, and IQ in 110 children with ASD, typical development, or an intermediate behavioral profile. While motor challenges were more prevalent in the ASD group compared to other groups, sensory symptom severity and IQ across all individuals best predicted motor performance above-and-beyond group status. Therefore, motor challenges may be best characterized by individual variation in sensory features and cognitive abilities rather than diagnostic group.

Auditory-motor rhythm synchronization in children with autism spectrum disorder / Ana TRYFON in Research in Autism Spectrum Disorders, 35 (March 2017)

HYDE, Auteur Article en page(s) : p.51-61 Langues : Anglais (eng) Mots-clés : Autism  Auditory  Motor  Rhythm  Synchronization  Development Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by difficulties in social and communication skills as well as atypical sensory perception and motor skills. Sensorimotor abilities such as auditory-motor integration are essential for social interaction and communication. The goal of this research was to investigate the development of auditory-motor rhythm synchronization for the first time in ASD versus typically-developing (TD) children. Methods Participants were 31 boys with ASD and 23 TD boys that were matched in age and IQ. Participants were tested on an auditory-motor rhythm synchronization task in which they tapped in synchrony with rhythms of varying metrical complexity. Results Both children with ASD and TD performed similarly on this task and both groups performed better with age. This work demonstrates that non-verbal rhythm synchronization is intact in ASD over the course of childhood development. This research serves to better understand sensorimotor interactions in ASD and to better define sensory phenotypes in ASD.

Brainstem White Matter Predicts Individual Differences in Manual Motor Difficulties and Symptom Severity in Autism / Brittany G. TRAVERS in Journal of Autism and Developmental Disorders, 45-9 (September 2015)

This study investigated if atypical white matter microstructure in the brain mediated the relationship between motor skills and ASD symptom severity. Sixty-seven males with ASD and 42 males with typical development (5–33 years old) completed a diffusion tensor imaging scan and measures of grip strength, finger tapping, and autism symptom severity. Within the ASD group, weaker grip strength predicted more severe autism symptoms. Fractional anisotropy of the brainstem’s corticospinal tract predicted both grip strength and autism symptom severity and mediated the relationship between the two. These findings suggest that brainstem white matter may contribute to autism symptoms and grip strength in ASD.

Catatonia: The Ultimate yet Treatable Motor Reaction to Fear in Autism / Dirk M. DHOSSCHE in Autism - Open Access, 1-1 (December 2011)  

Public ISBD [article]  inAutism - Open Access > 1-1 (December 2011) . - 5 p. Titre : Catatonia: The Ultimate yet Treatable Motor Reaction to Fear in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Dirk M. DHOSSCHE, Auteur Année de publication : 2011 Article en page(s) : 5 p. Langues : Anglais (eng) Mots-clés : Catatonia  Autism  Fear  Anxiety  Motor  Tonic;Immobility Index. décimale : PER Périodiques Résumé : Background: Catatonia is a unique syndrome characterized by specific motor signs, at times life-threatening when aggravated by autonomic dysfunction and fever, yet treatable if recognized early. Catatonia occurs in patients with various disorders including autism and related developmental disorders. Sometimes catatonia develops after severe psychological trauma, supporting the view that it is an extreme motor reaction to fear. Methods: Review of literature on the role of fear in the development of catatonia in autism, and its treatment. Results: There are no empirical studies in the literature addressing the role of fear in the development of catatonia in autism. Case-reports support that stressful events often precede the development of catatonia in autistic people and that catatonia in autism is a treatable syndrome, often requiring psychosocial interventions to reduce anxiety, and the use of benzodiazepines, electroconvulsive therapy, and maintenance electroconvulsive therapy for safe reversal. Autistic people may be particularly vulnerable to catatonia due to social, cognitive, and sensory deficits. Conclusion: Further studies are warranted in autistic people, measuring states of anxiety in response to various stressors, and assessing their relationship to catatonia, and applying various treatments including benzodiazepines, electroconvulsive therapy, and psychosocial interventions, in those with catatonia.
