  1. Canonical correlation analysis between 6 sets of variables. SD = Mean Standard Deviation. λS* = maximal Lyapunov exponent, short term dynamic stability. λ:* = maximal Lyapunov exponent, long term dynamic stability. α = scaling exponent (Detrended Fluctuation Analysis), fractal dynamics. ML, V and AP stand for respectively Medio-Lateral, Vertical and Antero-posterior.
