Association between CoP and cane displacement. (A) The displacement of the CoP along the frontal plane (M-L) was plotted against the cane movement in the same plane recorded during one 10-s period in which the cane rested on the ground in one subject EC. When the CoP moved to the right (positive values in the ordinate) also the cane moved to the right (positive values in the abscissa). (B) Mean time-lag between CoP and cane movement across subjects. Negative values of time-lag indicate that the cane movements lagged the CoP movements.
