Automated and scalable Computerized Assessment of Motor Imitation (CAMI) in children with Autism Spectrum Disorder using a single 2D camera: A pilot study / Daniel E. LIDSTONE in Research in Autism Spectrum Disorders, 87 (September 2021)

MOSTOFSKY, Auteur Article en page(s) : 101840 Langues : Anglais (eng) Mots-clés : Autism  Imitation  Intervention  Social behavior  OpenPose Index. décimale : PER Périodiques Résumé : Background Motor imitation difficulties are pervasive in children with Autism Spectrum Disorder (ASD). Previous research demonstrated the validity and reliability of an algorithm called Computerized Assessment of Motor Imitation (CAMI) using 3D depth cameras. However, incorporating CAMI into serious games and making it accessible in clinic and home settings requires a more scalable approach that uses “off-the-shelf” 2D cameras. Method In a brief (one-minute) task, children (23 ASD, 17 typically developing [TD]) imitated a model’s dance movements while simultaneously being recorded using Kinect Xbox motion tracking technology (Kinect 3D) and a single 2D camera. Pose-estimation software (OpenPose 2D) was used on the 2D camera video to fit a skeleton to the imitating child. Motor imitation scores computed from the fully automated OpenPose 2D CAMI method were compared to scores computed from the Kinect 3D CAMI and Human Observation Coding (HOC) methods. Results Motor imitation scores obtained from the OpenPose 2D CAMI method were significantly correlated with scores obtained from the Kinect 3D CAMI method (r40 = 0.82, p < 0.001) and the HOC method (r40 = 0.80, p < 0.001). Both 2D and 3D CAMI methods showed better discriminative ability than the HOC, with the Kinect 3D CAMI method outperforming the OpenPose 2D CAMI method (area under ROC curve (AUC): AUCHOC = 0.799, AUC2D-CAMI = 0.876, AUC3D-CAMI = 0.94). Finally, all motor imitation scores were significantly associated with the social-communication impairment (all p ? 0.003). Conclusions This pilot-study demonstrated that motor imitation can be automatically quantified using a single 2D camera.

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?

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?
