Abstract
The present invention relates to a determination system, a corresponding determination method and a computer program for determining a sleep stage of a subject. The determination system comprises a cardiorespiratory signal providing unit (), an actigraphy data providing unit (), a first sleep stage determination unit () for determining the sleep stage based on a cardiorespiratory signal, and a second sleep stage determination unit () for determining the sleep stage based on actigraphy data.

The sleep stage of the subject is determined using the first sleep stage determination unit () up to the SOL and the second sleep stage determination unit () after the SOL. The determination system and corresponding method allow for a more reliable determination of a sleep stage of subject, in particular improve the determination of the SOL of the subject.
