The effects of an early motor skill intervention on motor skills,levels of physical activity,and socialization in young children with autism spectrum disorder: A pilot study

Abstract

Despite evidence suggesting one of the earliest indicators of an eventual autism spectrum disorder diagnoses is an early motor delay, there remain very few interventions targeting motor behavior as the primary outcome for young children with autism spectrum disorder. The aim of this pilot study was to measure the efficacy of an intensive motor skill intervention on motor skills (Test of Gross Motor Development-2), physical activity (accelerometers), and socialization (Playground Observation of Peer Engagement) in young children with autism spectrum disorder. A total of 20 children with autism spectrum disorder aged 4–6 years participated. The experimental group (n = 11) participated in an 8-week intervention consisting of motor skill instruction for 4 h/day, 5 days/week. The control group (n = 9) did not receive the intervention. A repeated-measures analysis of covariance revealed statistically significant differences between groups in all three motor outcomes, locomotor (F(1, 14) = 10.07, p < 0.001, partial η² = 0.42), object control (F(1, 14) = 12.90, p < 0.001, partial η² = 0.48), and gross quotient (F(1, 14) = 15.61, p < 0.01, partial η² = 0.53). Findings shed light on the importance of including motor programming as part of the early intervention services delivered to young children with autism spectrum disorder.
