Table 1.
Subjects’ age, height, weight and stance width. Data are presented as mean (SD). Stance width was calculated as the mean distance between the left and right lateral ankles and 5th MP joints in the ML direction prior to the onset of perturbation. No significant differences were found between Non-Fallers and Fallers (p≥.087).
