Comparisons of SOT performance of EH and AH between the fallers and non-fallers. The main effects of SOT performance (F_{1, 492 =} 9.35, p < 0.01) and non-fallers/fallers (F_{1, 492 =} 13.2, p < 0.01) were significant, with the interaction between the two factors being also significant (F_{1, 492 =} 4.58, p < 0.05). The graphical symbol of “**” indicates p < 0.01. SOT, step-over test; EH, estimated height; AH, actual height.
