However, it is relatively unknown whether VMI impairments are specific to children with ASD versus children with other neurodevelopmental disorders. As such, this study addressed the hypothesis that children with ASD, but not those in other clinical control groups, would show greater deficits in high-VMI dynamic grip-force tracking versus low-VMI static presentation. Seventy-nine children, aged 7-17?years, participated: 22 children with ASD, 17 children with fetal alcohol spectrum disorder (FASD), 18 children with Attention-Deficit Hyperactivity Disorder (ADHD), and 22 typically developing (TD) children. Two grip-force tracking conditions were examined: (1) a low-VMI condition (static visual target) and (2) a high-VMI condition (dynamic visual target). Low-frequency force oscillations <0.5 Hz during the visuomotor task were also examined. Two-way ANCOVAs were used to examine group x VMI and group x frequency effects (? = 0.05). Children with ASD showed a difficulty, above that seen in the ADHD/FASD groups, tracking dynamic, but not static, visual stimuli as compared to TD children. Low-frequency force oscillations <0.25?Hz were also significantly greater in the ASD versus the TD group. This study is the first to report VMI deficits during dynamic versus static grip-force tracking and increased proportion of force oscillations <0.25?Hz during visuomotor tracking in the ASD versus TD group. Dynamic VMI impairments may be a core psychophysiologic feature that could contribute to impaired development of motor and social-communicative skills in ASD. LAY SUMMARY: Children with autism spectrum disorder (ASD) show difficulties using dynamic visual stimuli to guide their own movements compared to their typically developing (TD) peers. It is unknown whether children without a diagnosis of ASD, but with other neurological disorders, show similar difficulties processing dynamic visual stimuli. In this study, we showed that children with ASD show a difficulty using dynamic, but not static, visual stimuli to guide movement that may explain atypical development of motor and social skills.

Examining the specificity of postural control deficits in children with Autism Spectrum Disorder using a cross-syndrome approach / Daniel E. LIDSTONE in Research in Autism Spectrum Disorders, 72 (April 2020)

However, identification of specific postural sway features that differentiate ASD from other neurodevelopmental disorders has not been examined. The current study employs a cross-syndrome approach by comparing postural sway area and direction-specific features of sway magnitude, sway velocity, and sway complexity between children with ASD, Fetal Alcohol Spectrum Disorder (FASD), Attention-Deficit Hyperactivity Disorder (ADHD), and typically developing (TD) controls. Method Eighty children (7–17 years old) participated in this study. Postural sway was measured on a force plate during 30-s of bilateral quiet stance and balance was assessed using a timed unipedal stance test. Results Results showed that (1) postural sway area and mediolateral (ML) sway magnitude were significantly greater in children with ASD vs. all groups (p?

DUFEK, Auteur Article en page(s) : 101546 Langues : Anglais (eng) Mots-clés : Cross-syndrome  Manual dexterity  FASD  ASD  Asymmetry Index. décimale : PER Périodiques Résumé : Background Manual dexterity (MD) is important for performing most activities of daily living, and children with ASD show MD deficits. However, the specificity of MD deficits in children with ASD has not previously been examined. Similar to children with ASD, extant evidence suggests children with Fetal Alcohol Spectrum Disorder (FASD) and Attention-Deficit Hyperactivity Disorder (ADHD) also show MD impairments. The purpose of this study was to examine the specificity MD deficits in children with ASD using a cross-syndrome design. We examined dominant (D) and non-dominant (ND) hand performance using a relatively large sample of children with ASD, FASD, ADHD, and typically developing (TD) children. Method Seventy-two right-handed children (7–17 years old) participated in this study. To examine MD, the 9-hole pegboard test was completed on the D and ND-hands. The fastest time of three attempts was recorded. HPA was defined as the percent difference between D and ND-hand times. Results D-hand MD was significantly worse in children with ASD vs. typically developing (TD) children (p?=?0.002). ND-hand dexterity was significantly worse in children with ASD vs. FASD (p?=?0.049) and TD groups (p?=?0.004). Hand performance asymmetry (HPA) was significantly lower in the FASD group compared to both the ASD and ADHD groups (p?
