Abstract
The authors present the preliminary results of the analysis of the centre of mass behavior during treadmill walking by means of the sample entropy which quantifies a regularity of a time series. The research is focused on the centre of mass trajectories in the mediolateral, anteroposterior and longitudinal axes recorded using the motion capture technique. From among several entropy measures the sample entropy was chosen for the purpose of assessment of the influence of both walking speed and ground inclination on a regularity in movements of the centre of mass. The results were compared with the sample entropy values for periodic, chaotic and stochastic signals.
