Pronation and supination is the one of the soft neurological signs which shows the abnormality in children with developmental disorders such as ADHD or autistic syndrome. We developed a portable system to evaluate pronosupination by wireless acceleration and angular velocity sensors. In order to evaluate the difference between typically developing children and children with ADHD, we measured pronation and supination of typically developing children and children with ADHD. Accuracy, cooperativeness and stability were investigated to analyze the pronation and supination. We obtained the reference curve of the neuromotor development of children. Our results suggested that the pronation and supination function in children with ADHD has a tendency to lag behind that of typically developing children by several years. We also investigated the feature of elderly people. From these results, our system has a possibility to objectively evaluate the neurodevelopmental delay of children with ADHD and neuromotor dysfunction of elderly people.
