Abstract:
Quantitative analysis of wrist actigraphy data recorded in real life is a topic of growing interest. For historical reasons, most of that data is collected using a one minute epoch, i.e. the system stores one piece of data each minute, and recordings are limited to a few days. When the data is used for wake/sleep studies, the “gold standard” reference is the Polysomnography (PSG) and little is known about the correlation of actigraphy data with epochs shorter than one minute. It is unknown what is the quantitative impact of infradian rhythms, that could be longer than one year, on shorter recordings. To explore those two areas, the only option is to make longer recordings with shorter epochs. We present a set of data, collected as part of a larger project. For the first time, this paper makes available one year of wrist actimetry in real life, stored at one second epochs. A first evaluation of that data calls for new ways for actimetry analysis and actigraphy display. The raw data is available to the public.
