Abstract: We examine postural sway data using concepts of nonextensive thermostatistics. We show that nonextensive thermostatistical cutoff distributions fit approximately empirically observed distributions of postural sway data. We show that the index of nonextensivity of these cutoff distributions is larger for elderly subjects than for younger subjects. A preliminary interpretation of the nonextensivity parameter as a measure for explorative versus conservative behavior is given.
