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)

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.

Brief Report: Children with ADHD Without Co-morbid Autism do not have Impaired Motor Proficiency on the Movement Assessment Battery for Children / Nicole PAPADOPOULOS in Journal of Autism and Developmental Disorders, 43-6 (June 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-6 (June 2013) . - p.1477-1482 Titre : Brief Report: Children with ADHD Without Co-morbid Autism do not have Impaired Motor Proficiency on the Movement Assessment Battery for Children Type de document : Texte imprimé et/ou numérique Auteurs : Nicole PAPADOPOULOS, Auteur ; Nicole J.

MCGINLEY, Auteur Article en page(s) : p.1477-1482 Langues : Anglais (eng) Mots-clés : Autism  ADHD  Co-morbidity  Motor performance Index. décimale : PER Périodiques Résumé : Motor proficiency was investigated in a sample of children with Attention Deficit Hyperactivity Disorder-Combined type (ADHD-CT) without autism. Accounting for the influence of co-morbid autistic symptoms in ADHD motor studies is vital given that motor impairment has been linked to social–communication symptoms in children who have co-morbid ADHD and autistic-like symptoms. Two groups of children aged between 7–14 years were recruited; children with ADHD-CT (n = 16; mean age 10 years, 7 months [SD = 1 year, 10 months]) and a typically developing (n = 16; mean age 10 years, 6 months [SD = 2 years, 6 months]) group. Motor proficiency was measured using the Movement Assessment Battery for Children-2nd Edition, ADHD symptoms were measured using the Conner’s Parent Rating Scale. Children with ADHD-CT who had been screened for co-morbid autism did not display motor difficulties on the MABC-2. Higher levels of inattention, but not hyperactivity or impulsivity were associated with poorer motor performance. These findings provide indirect evidence that the motor problems that children with ADHD experience may be related to co-occurring social responsiveness impairments.

Differentiation of High-Functioning Autism and Asperger’s Disorder Based on Neuromotor Behaviour / Ashwini NAYATE in Journal of Autism and Developmental Disorders, 42-5 (May 2012)

Although currently listed as distinct clinical disorders, the validity of their distinction remains controversial. This study examined gait in children with autism and AD. Eleven children with high-functioning autism and eleven children with AD completed a series of walking tasks. Results indicated distinct movement disturbance; these findings are discussed in light of seminal papers in this field by Vilensky et al. (Arch Neurol 38:646–649, 1981) and Hallett et al. (Arch Neurol 50:1304–1308, 1993) who interpret the gait of individuals with autism using parkinsonian and cerebellar-ataxia patient models, respectively. Distinctions in gait patterns implicating perhaps unique motor circuit disturbances support the hypothesis that autism and AD may have unique neurodevelopmental trajectories.

Do Planning and Visual Integration Difficulties Underpin Motor Dysfunction in Autism? A Kinematic Study of Young Children with Autism / Ariane M. DOWD in Journal of Autism and Developmental Disorders, 42-8 (August 2012)

Consistent with prior findings in older children, a difference in movement preparation was found in the autism group (n = 11) relative to typically developing children. In contrast to typically developing children, the presence of a visual distractor in the movement task did not appear to impact on early movement planning or execution in children with autism, suggesting that this group were not considering all available environmental cues to modulate movement. The findings from this study are consistent with the possibility that autism is associated with a difficulty using visual information to prime alternative movements in a responsive way to environmental demands.

Motor proficiency and emotional/behavioural disturbance in autism and Asperger’s disorder: another piece of the neurological puzzle? / Nicole PAPADOPOULOS in Autism, 16-6 (November 2012)

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.
