A 2021 study by Lavenne-Collot confirmed what we see in the clinic – children with ASD crawl on hands and knees 25% less than neurotypical children. Other observations noted were difficulty getting into sitting independently and independent walking. Interesting (but not surprising) is that all of these milestones are characterized as transitional movements rather than static positions. This reinforces anticipatory postural control as a crucial component in the development of dynamic movement control.
