    Sleep-wake detection and computation of sleep continuity from a wrist unit in children, adolescents and adults

    This work first aims at demonstrating a new accelerometer-based sleep-wake detection algorithm. Results are shown against gold standard polysomnography (PSG), in adults. We also used subjective sleep quality m...
