| Research Abstract |
The purpose of this study was to develop sleep monitor systems for children using a non restrictive way, and to this end we proposed a new diagnosis method for developmental disorders. We examined normal developed children using polysomnography(PSG) and video analysis. The linear discriminant function method was used to estimate the sleep stage from body movements calculated from video image. Overall, the average agreement rate for sleep stage was approximately 70%. The results revealed that the transition between sleep stages could be successfully estimated by body movement during sleep. Next, we made a comparison between normal developed children and ADHD children in body movement by video images as a clinical application. As the results, there was a remarkable difference in Stage 3 and we suggest that this difference may be used as a marker in the diagnosis of ADHD.
