The measurement normally takes place every minute. The equipment records movement with the use of an accelerometer. The importance of actigraphy resides in the possibility of a full understanding of this overview How does actigraphy work?Īctigraphy is performed through an actimeter, a device that normally looks a lot like a watch and is commonly used on the individual’s non-dominant arm. The consequences of the interaction of day and night cycles are also observed in humans, where physiological events such as a decrease or increase in respiratory rate, hormone release, thermoregulation, among others, present oscillation in periods of approximately 24 hours and can be analyzed longitudinally, so that it is possible to get a complete overview of what happens in the human body over the course of a day. This phenomenon had a strong influence on the evolutionary process so that a series of physiological and behavioral oscillations are expressed synchronously whilst the interaction with said periods took place. It is common for most living beings to continuously interact with a constant period of environmental change: the cycle of day and night, which results from the rotation of the Earth. Are there other applications of actigraphy besides sleep medicine?.However, we think it is important to go deeper into the subject, and we will do so throughout this article by detailing the definitions, getting to know new technologies and presenting answers to questions such as: This is how we practically and directly define actigraphy. Through it, constant non-invasive data capture occurs, as well as the compilation and processing of information aimed at the analyses of the pace of sleep/wakefulness over long periods of time, identifying phases of activity and rest. We have modified baby socks so that the actimeter is placed in a small pocket on the outer side of the ankle.What is actigraphy? Discover how it can be applied to different areas of medicineīy understanding how actigraphy works, it is possible to apply the method in several areas.Īctigraphy (or actimetry) is the method of monitoring activity-rest cycles. The actimeter is attached to the child’s left leg. We use the actimeter from Geneactiv, which is small (43 mm x 40 mm x 13 mm) and light (16 g). Therefore, as a supplement to the actimeter, a sleep diary is also kept, where the child’s sleep periods, as well as its eating and crying, are reported. Conclusions from actimetry can be complex, especially if there is external movement during sleep, for example when the baby is sleeping in a pram or sling. The movement sensor therefore indirectly measures sleep. This method is based on the fact that movements during sleep are reduced and less frequent compared to the waking state. In our studies we need movement sensors (=actimeters) to draw conclusions about the sleep-wake rhythm. ![]() We wish to measure sleep as normally as possible, and a familiar environment is important for this. ![]() Our assessments take place at the families’ homes.
