Virtual-reality enables researchers to study movement in safe, engaging environments. We used motion-capture to measure how 7-13-year-old autistic and neurotypical children make whole-body movements in a virtual-reality task. Although children in both groups were successful, we observed differences in their movements. Autistic children were less efficient moving to the target. Autistic children did not appear to use a movement strategy. While neurotypical children were more likely to overshoot near targets and undershoot far targets, autistic children did not modulate their strategy. Using kinematic data from tasks in virtual-reality, we can begin to understand the pattern of movement challenges experienced by autistic children.

Characterizing goal-directed whole-body movements in autistic children and children with developmental coordination disorder / Stacey B. HIRSCH ; Priscila M. TAMPLAIN ; Tylan N. TEMPLIN ; Gabriela M.

Both autistic children and children with developmental coordination disorder exhibit clinically-significant motor difficulties with substantial differences in postural control. Postural control has been examined extensively in these groups independently, but there has been little research comparing them in the same study. Methods We examined dynamic postural control in autistic children, children with developmental coordination disorder, and neurotypical children using an immersive virtual reality task. Children moved a user-controlled ball to a static target using whole-body movements. Results Children in all three groups were able to move their ball to the target successfully, but there were significant differences in their movement characteristics (e.g., trial duration, path efficiency, log dimensionless jerk, movement types). There was a similar trend for each of the movement characteristics: autistic children performed significantly worse than neurotypical children, and children with developmental coordination disorder had varied performance compared to neurotypical and autistic children. Conclusion These findings provide clear support for our hypotheses that autistic children have difficulty with goal-directed whole-body movements, and that these movements are similarly different from neurotypical children?s movements. They provide mixed support for our hypothesis that children with developmental coordination disorder differ in their goal-directed body movements. By understanding the similarities and differences in motor difficulties across neurodevelopmental conditions, we can begin to develop motor interventions specifically targeted to the unique motor profiles of these populations.

Community-based postural control assessment in autistic individuals indicates a similar but delayed trajectory compared to neurotypical individuals / Nicholas E. FEARS in Autism Research, 16-3 (March 2023)  

Public ISBD [article]  inAutism Research > 16-3 (March 2023) . - p.543-557 Titre : Community-based postural control assessment in autistic individuals indicates a similar but delayed trajectory compared to neurotypical individuals Type de document : Texte imprimé et/ou numérique Auteurs : Nicholas E.

MILLER, Auteur Article en page(s) : p.543-557 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autistic individuals exhibit significant sensorimotor differences. Postural stability and control are foundational motor skills for successfully performing many activities of daily living. In neurotypical development, postural stability and control develop throughout childhood and adolescence. In autistic development, previous studies have focused primarily on individual age groups (e.g., childhood, adolescence, adulthood) or only controlled for age using age-matching. Here, we examined the age trajectories of postural stability and control in autism from childhood through adolescents using standardized clinical assessments. In study 1, we tested the postural stability of autistic (n = 27) and neurotypical (n = 41) children, adolescents, and young adults aged 7-20?years during quiet standing on a force plate in three visual conditions: eyes open (EO), eyes closed (EC), and eyes open with the head in a translucent dome (Dome). Postural sway variability decreased as age increased for both groups, but autistic participants showed greater variability than neurotypical participants across age. In study 2, we tested autistic (n = 21) and neurotypical (n = 32) children and adolescents aged 7-16?years during a dynamic postural control task with nine targets. Postural control efficiency increased as age increased for both groups, but autistic participants were less efficient compared to neurotypical participants across age. Together, these results indicate that autistic individuals have a similar age trajectory for postural stability and control compared to neurotypical individuals, but have lower postural stability and control overall.
