dc.description.abstract [eng] Human motor activity is constrained by the rhythmicity of the 24 hours circadian cycle, including the usual 12-15 hours wake-sleep cycle. However, activity fluctuations also appear over a wide range of temporal scales, from days to few seconds, resulting from the concatenation of myriad of individual smaller motor events. Furthermore, individuals present different propensity to wakefulness and thus to motor activity throughout the circadian cycle. Are activity fluctuations across temporal scales intrinsically different, or is there an universal description encompassing them? Is this description also universal across individuals, considering the aforementioned variability? Here we establish the presence of universality in motor activity fluctuations based on the empirical study of a month of continuous wristwatch accelerometer recordings. We study the scaling of average fluctuations across temporal scales and determine an universal law characterized by critical exponents α, τ and 1/μ. Results are highly reminiscent of the universality described for the average shape of avalanches in systems exhibiting cracking noise. Beyond its theoretical relevance, the present results can be important for developing objective markers of healthy as well as pathological human motor behavior.
