Postural asymmetry in human stance: the mean center of pressure position

The aim of this study is to point out the influence of the feet position on the mean center of pressure (COP) position for a population of 25 healthy young right-handed men. Results have been compared to those of the literature. Most of them have been confirmed: mean COP position is on the subject's right side, that points out the asymmetry of the orthostatic posture. Moreover, the findings showed the feet position effects : when the clearance and/or the angle between the feet increase the mean COP moves backward and to the right.
