Fig. 2

Box plots of the CoM position (a, b) and CoM variability (c, d). Box plots of CoM indices in Faller (grey boxes) and Nonfaller (white boxes) for three phases, Early-, Mid-, and Late-SS phases are shown. Dots represent values in each subject. The horizontal line displays the median and the box-edges display the 25th and 75th percentiles. Upper panels: CoM position in the ML (a) and in V (b) directions; Lower panels: CoM variability in the ML (c) and V (d) directions. V direction: vertical direction, ML direction: mediolateral direction, SS: single stance phase. Statistically significant major effects are shown with one star (p < 0.05)
