ABSTRACT
Until now, the feet position effect on orthostatic posture has been investigated only in male or mixed sample groups. However, literature reports gender differences on orthostatic equilibrium. In order to study the effect of feet position on females and to complete the previous works, we tested a homogenous female sample group with 16 feet positions. Most of our results are in agreement with those already observed in male or mixed sample groups. The increase of the base of support induces an improvement of the orthostatic balance mainly on the medio-lateral axis. The stabilizing effect of the inner feet distance increase is more important than the one of the angle. We also noticed that the mean center of pressure position is located on the subjects' right side.
