An exemplar plot of the 12 measures (ML direction: Fy, Mx, Hay, Hrv, Tay, Trv and AP direction: Fx, My, Hax, Hpv, Tax, Tpv) of interest for one subject during the balance task, for both baseline and stimulus periods for an optimal trial at the level of 350 μA (= 40% of this subjects perceptual threshold).

Numerals in the bottom right of each panel represent RMS value.
