Brief report: Parent-guided movements during play with children with autism spectrum disorder.

Background: Children with autism spectrum disorder (ASD) demonstrate social and communication impairments from an early age. While researchers have long investigated parenting behaviors in relation to children's social and communication development, fewer studies have examined the relevance of movement-based parenting behaviors to facilitating communication and social engagement with young children. The present study aimed to investigate: (1) parent-guided movements (PGMs) within dyads of parents and typically developing (TD) children and children with ASD; and (2) children's ASD diagnostic and receptive language scores as predictors of PGM frequency.

Analysis of gait synchrony and balance in neurodevelopmental disorders using computer vision techniques.

Gait tasks are commonly administered during motor assessments of children with neurodevelopmental disorders (NDDs). Gait analyses are often conducted in laboratory settings using costly and cumbersome experiments. In this paper, we propose a computational pipeline using computer vision techniques as an ecological and precise method to quantify gait in children with NDDs with challenging behaviors.

Assessing Child Postural Variability: Development, Feasibility, and Reliability of a Video Coding System.

Aims: Postural variability is central to children's locomotion, motor control, and environmental exploration, and lacks standardized methods for systematic assessment. The purpose of this study was to develop and evaluate the feasibility and interrater reliability of Child Posture Variability Coding (CPVC), a method of quantifying postural variability in young children.

Method: Videos of parent-child play interactions obtained from a longitudinal study investigating language acquisition in typically developing (TD) children and children with autism spectrum disorder (ASD) were used to develop 33 codes for children's voluntary changes in static and dynamic postures.
