The reach-to-grasp movement in infants later diagnosed with autism spectrum disorder: a high-risk sibling cohort study / Lori-Ann R. SACREY in Journal of Neurodevelopmental Disorders, 10-1 (December 2018)
[article]
Titre : The reach-to-grasp movement in infants later diagnosed with autism spectrum disorder: a high-risk sibling cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Lori-Ann R. SACREY, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Susan E. BRYSON, Auteur ; Jessica BRIAN, Auteur ; I. M. SMITH, Auteur Année de publication : 2018 Article en page(s) : 41 p. Langues : Anglais (eng) Mots-clés : Autism Autism spectrum disorder Baby siblings Infant siblings Motor Motor skills Reaching Index. décimale : PER Périodiques Résumé : BACKGROUND: Although autism spectrum disorder (ASD) is characterized by impairments in social communication and the presence of repetitive behavior and/or restricted interests, there is evidence that motor impairments may be a contributing factor to the ASD phenotype. The purpose of this study was to examine the motor act of reaching-to-grasp in children at high risk (HR; with an older sibling diagnosed with ASD) and low-risk (LR; no family history of ASD) for ASD. METHODS: Children were compared for differences in reaching-to-grasp based on sibling status and diagnostic outcome. Children were enrolled between 6 and 12 months of age and the reach-to-grasp movement was scored at 6, 9, (where available) 12, 15, 18, 24, and 36 months of age using the qualitative Skilled Reaching Rating Scale to determine the presence of any group-, age-, or sex-related differences in the mechanics of the reach-to-grasp movement using a Mixed Models analysis. At 36 months, all children underwent a gold-standard diagnostic assessment, which resulted in three outcome groups: HR children diagnosed with ASD (HR-ASD; n = 10), HR children not diagnosed with ASD (HR-N; n = 10), and low-risk children not diagnosed with ASD (LR; n = 10). RESULTS: The group of children who were later diagnosed with ASD (HR-ASD group) showed higher (worse) total scores on the reach-to-grasp movement, as well as higher scores on the components of Orient, Lift, and Pronate compared to children in the LR and HR-N groups. CONCLUSIONS: Our results support the growing literature indicating that children who are later diagnosed with ASD show impaired early motor performance. These results highlight the importance of early surveillance of children who are at elevated risk for ASD, and early initiatives should focus on early signs of the phenotype, including both movement and sensory differences (prodromal signs) prior to the emergence of diagnostic characteristics.

JOHNSON, Auteur ; Emily J. H. JONES, Auteur Article en page(s) : p.4367-4384 Langues : Anglais (eng) Mots-clés : Attention deficit hyperactivity disorder Autism spectrum disorder Midline crossing Motor ability Reaching Index. décimale : PER Périodiques Résumé : We investigated infant's manual motor behaviour; specifically behaviours crossing the body midline. Infants at elevated likelihood of Autism Spectrum Disorder (ASD) and/or Attention Deficit Hyperactivity Disorder (ADHD) produced fewer manual behaviours that cross the midline compared to infants with a typical likelihood of developing these disorders; however this effect was limited to 10-month-olds and not apparent at age 5 and 14 months. Although, midline crossing did not predict ASD traits, it was related to ADHD traits at 2 years of age. We rule out motor ability and hand dominance as possible explanations for this pattern of behaviour, positing that these results may be a consequence of multisensory integration abilities, and the neurobehavioural shift period, in the first year of life.

Titre : Three-Dimensional Kinematic Analysis of Prehension Movements in Young Children with Autism Spectrum Disorder: New Insights on Motor Impairment Type de document : Texte imprimé et/ou numérique Auteurs : Giovanna Cristina CAMPIONE, Auteur ; Caterina PIAZZA, Auteur ; Laura VILLA, Auteur ; Massimo MOLTENI, Auteur Article en page(s) : p.1985-1999 Langues : Anglais (eng) Mots-clés : Grasping Reaching Kinematics Feedforward Sensory-control-feedback Autism-spectrum-disorder Index. décimale : PER Périodiques Résumé : The study was aimed at better clarifying whether action execution impairment in autism depends mainly on disruptions either in feedforward mechanisms or in feedback-based control processes supporting motor execution. To this purpose, we analyzed prehension movement kinematics in 4- and 5-year-old children with autism and in peers with typical development. Statistical analysis showed that the kinematics of the grasp component was spared in autism, whereas early kinematics of the reach component was atypical. We discussed this evidence as suggesting impairment in the feedforward processes involved in action execution, whereas impairment in feedback-based control processes remained unclear. We proposed that certain motor abilities are available in autism, and children may use them differently as a function of motor context complexity.
