Doctors can soon diagnose autistic children using a new movement monitoring video game tool, which can distinguish autistic children from their non -autistic peers with a success rate of 80 percent.
The game could also distinguish children with autism from those with ADHD, two diagnoses that are often judged, with a accuracy of 70 percent.
The tool is called the computerized evaluation of the imitation of the motor or cami. In the game, a child is asked to continue along with the dance movements of the entire body of a character on screen for 1 minute. Meanwhile, two cameras, one on the front, one behind, records the child’s movements, and then the CAMI system evaluates the child’s imitation score.
These vary from zero, which is not imitation at all, to 1, which is a ‘perfect’ imitation, based on the ability of a well -trained researcher to imitate avatar.

While the traditional understanding of autism often focuses on social communication difficulties, investigation has demonstrated Sensory-motor difficulties play an important role in the condition, and can even be the basis of some of the communication challenges.
Autistic children often have problems imitating movements and expressions, which through body language make up a key component of human communication.
“Cami takes advantage of these sensory-motor difficulties, which shows that they are not shared with children with ADHD.” says Psychology Researcher at the University of Nottingham Trent Bahar Tunçgenç.
The study tested the tool in 183 children from 7 to 13 years. Among this group, 21 children had an exclusive diagnosis of autistic spectrum disorder (ASD)35 had an exclusive diagnosis of ADHD (hyperactivity care deficit disorder), 63 had concurrent ASD and ADHD, and 65 were neurotypical, which means they had no diagnosis.
The children were evaluated for autism and symptoms of ADHD using traditional diagnostic tools, along with a CAMI score based on their video game performance.
Among autistic children, there was a strong association between the low Cami scores and the increase in autism symptoms, especially social affection measures, as well as restricted and repetitive behaviors.
However, their low Cami scores were not associated with ADHD or motor capacity traits. For neurotypic children, on the other hand, CAMI scores are closely related to lack of attention and motor capacity.
The ADHD group received higher CAM scores than children with ASD and ADHD, but their scores were not significantly different from the SOL Group, which suggests that the system may need some refinement before it can be trusted for diagnosis.
“What really makes Cami so exciting is its simplicity,” Tunçgenç says. “Video games are already very popular. It is fun for children and offers rapid results that are easy to interpret for doctors. I hope you eventually be used in clinical practices everywhere.”
