Abstract
In this work we discuss the multidimensional scoring approach proposed 
by Bargiotas and al. [I. Bargiotas, J. Audiffren, N. Vayatis, P-P. 
Vidal, S. Buffat, A.P. Yelnik and Damien Ricard, On the importance of 
local dynamics in statokinesigram: a multivariate approach for postural 
control evaluation in elderly, PloS one, 13 (2018)] which locally 
characterizes statokinesigrams - the trajectory of the center of 
pressure, which is highly correlated with static balance quality - on 
small time intervals, or blocks. This approach highlights the local 
dynamics of the trajectories, and we show that the resulting 
characterization can be used to provide a global score in order to 
evaluate the postural control. We evaluate our approach using the 
statokinesigram of 126 community-dwelling elderly, and show that it 
provides an efficient tool to discriminate between fallers and non-fallers.
