Quantifying Repetitive Hand Flapping Kinematics in Autistic and Non‐Autistic Toddlers Using Video‐Based Pose Estimation

While repetitive behaviors such as hand flapping are associated with autism, non-autistic toddlers also exhibit this behavior (e.g., when excited), making clinically meaningful differences difficult to discern prior to age 2. Computer vision, a subfield of artificial intelligence (AI), has the potential to capture subtle movement differences that may otherwise be overlooked. We examined whether movement amplitude and frequency of repetitive hand flapping differed between autistic and non-autisti
