New research from Kennedy Krieger finds that a simple pull-to-sit task at six months of age may predict risk of an autism spectrum disorder. Researchers at Kennedy Krieger identified weak head and neck control as a red flag for autism and language and/or social developmental delays. This video is an example of the weak head and neck control; the infant is unable to maintain head alignment when being carefully, yet firmly, pulled by the arms from lying flat on his/her back to a sitting position. To see an example of typical neck/head/motor control, please visit http://youtu.be/HzJdR_gvnZ0 . For more information on this research,
