Using Movement to Diagnose and Treat Autism?

We know that kids with ASD process movement differently than their typically developing peers.  OTs and PTs who work with children/students on the Autism spectrum address the disruption of movement/motor planning issues and motor delays, but I recently came across an article that referenced a study that suggests that the movement profiles of kids with ASD "were unique enough to distinguish how severely affected children were by the developmental disorder. All the autistic participants — regardless of their age — were essentially stunted in their ability to process movement by age three."
The article goes on to further suggest that there may be a way to "both diagnose autism via movement patterns, and potentially treat the condition using similar action-based strategies."

It is an interesting read.  Find it here:
