An investigation of upper limb motor function in high functioning autism and Asperger's disorder using a repetitive Fitts’ aiming task / Nicole PAPADOPOULOS in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)
[article]
Titre : An investigation of upper limb motor function in high functioning autism and Asperger's disorder using a repetitive Fitts’ aiming task Type de document : Texte imprimé et/ou numérique Auteurs : Nicole PAPADOPOULOS, Auteur ; Jennifer L. MCGINLEY, Auteur ; Bruce J. TONGE, Auteur ; John L. BRADSHAW, Auteur ; Kerryn SAUNDERS, Auteur ; Nicole J. RINEHART, Auteur Année de publication : 2012 Article en page(s) : p.286-292 Langues : Anglais (eng) Mots-clés : Motor performance Autism Asperger's disorder Cerebellum Movement control Fitts’ task Index. décimale : PER Périodiques Résumé : There is now a growing body of research examining movement difficulties in children diagnosed with high functioning autism (HFA) and Asperger's disorder (AD). Despite this, few studies have investigated the kinematic components of movement that may be disrupted in children diagnosed with these disorders. The current study investigated rapid aiming movements in 19 individuals diagnosed with HFA, 20 individuals diagnosed with AD and 18 typically developing (TD) controls. A novel touchscreen version of a Fitts’ aiming task was administered that required participants to make 10 reciprocal aiming movements between targets. Task difficulty was manipulated by varying the size and distance between targets. Movement time in the HFA and AD groups was comparable to TD controls. Children with HFA displayed more constant and variable error across repeated aiming attempts compared to the TD group that may be attributed to deficits in feedforward online refinement of movement. These findings are in accordance with previous gait, ocular motor, upper limb and neuroimaging studies that suggest that the cerebellum may underlie movement disturbance in individuals diagnosed with HFA. Additionally, differences in the nature of upper limb motor disturbance in HFA may serve as a useful future adjunct to clinical measures.

Titre : Motor proficiency and emotional/behavioural disturbance in autism and Asperger’s disorder: another piece of the neurological puzzle? Type de document : Texte imprimé et/ou numérique Auteurs : Nicole PAPADOPOULOS, Auteur ; Jennifer L. MCGINLEY, Auteur ; Bruce J. TONGE, Auteur ; John L. BRADSHAW, Auteur ; Kerryn SAUNDERS, Auteur ; Anna MURPHY, Auteur ; Nicole J. RINEHART, Auteur Année de publication : 2012 Article en page(s) : p.627-640 Langues : Anglais (eng) Mots-clés : Asperger’s disorder autism behavioural disturbance communication emotional disturbance motor performance Index. décimale : PER Périodiques Résumé : The relationship of motor proficiency with emotional/behavioural disturbance, autistic symptoms and communication disturbance was investigated in children diagnosed with autism and Asperger’s disorder (AD). The Movement Assessment Battery for Children was used as a measure of motor impairment, and the Developmental Behavioural Checklist was used as a measure of emotional/behavioural disturbance in the following groups: AD (n=22), high functioning autism (HFA) (n=23), LFA (n=8) and typically developing children (n=20). The HFA group had more difficulty with motor items, such as ball skills and balance, than did the AD group. There were significant positive correlations between impairments in motor proficiency (in particular ball skills and balance) and emotional/behavioural disturbance, autistic symptoms and communication disturbance. These findings are consistent with the hypothesis that there are qualitative and quantitative differences in the motor profile between autism and AD. In addition, the association between motor proficiency impairment and emotional/behavioural disturbance in autism and AD emphasizes the importance for screening of co-occurring emotional/behavioural symptoms in individuals with motor difficulties. These findings have implications for the potential use of adjunct motor measures in the diagnosis and definition of autism spectrum disorders.

Titre : Reducing Listening-Related Stress in School-Aged Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Gary RANCE, Auteur ; Donella CHISARI, Auteur ; Kerryn SAUNDERS, Auteur ; Jean-Loup RAULT, Auteur Article en page(s) : p.2010-2022 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Hearing Stress Remote microphone listening system Classroom amplification Index. décimale : PER Périodiques Résumé : High levels of stress and anxiety are common in children with Autism Spectrum Disorder (ASD). Within this study of school-aged children (20 male, 6 female) we hypothesised that functional hearing deficits (also pervasive in ASD) could be ameliorated by auditory interventions and that, as a consequence, stress levels would be reduced. The use of Ear-Level Remote Microphone devices and Classroom Amplification systems resulted in significantly improved listening, communication and social interaction and a reduction in physiologic stress levels (salivary cortisol) in both one-on-one and group listening situations.
