Once again it has been shown, by Collins and Deluca, that the stabilometric signal contains two kinds of information that could be distinguished by an artifice of calculation: information about the movements of the center of pressure and information about the movements of the center of gravity.
The analysis used by Collins and Deluca (analysis of diffusion of the stabilogram) puts forwards new stabilometric parameters to characterize these two types of informations: the diffusion coefficients. But an experimental study of these parameters shows that they are either too poorly sensitive, or too strongly correlated to conventional stabilometric parameters to be useful.
This study underlines that the parameter of length of the statokinesigram remains the best measure of the "dance" of the center of pressure.
