Este estudio piloto busca evaluar la validez de las mediciones de los indicadores de calidad del sueño en la Fitbit Flex® en su modo Normal (FF), un dispositivo comercial que permite la medición la actividad diaria y el sueño en el día a día, comparándolos registros con los del Actigraph GR3X®, (considerado el Gold Standard en la evaluación de la calidad del sueño mediante actigrafía. Para lo anterior, se ha contado con sesenta y siete personas sin trastornos del sueño que portaron de noche simultáneamente durante una semana los monitores FF y el AGT3X, ambos en la muñeca. Los resultados obtenidos muestran que, a pesar de la existencia de diferencias significativas entre los dos instrumentos de medida, la alta correlación e ICC sugieren que el dispositivo comercial FF puede ser una herramienta útil para valorar la calidad del sueño, aunque los valores obtenidos no pueden ser considerados intercambiables con los registros de AGT3X.


This pilot study pretends to evaluate the accuracy of Fitbit Flex®, a consumer device for diary register, for the evaluation of sleep quality, compared to Actigraph GR3X, one of the most recommended actigraphs for sleep evaluation. To achieve this, sixty seven subjects without sleep disorders used simultaneously both monitors, Fitbit Flex® and Actigraph GT3X®, during one week nights. Even the significative differences between both monitors, de high correlation values and the ICC suggest that Fitbit Flex commercial device could be a useful instrument for the sleep quality evaluation, assuming that this result can not be considered interchangeable with Actigraph GR3X.
