The Discriminant Value of Phase-Dependent Local Dynamic Stability of Daily Life Walking in Older Adult Community-Dwelling Fallers and Nonfallers

Figure 3

(a) of the log-median for fallers (red) and nonfallers (blue) defined by the state space reconstruction Method 1 (differential coordinate embedding) for initial perturbation at 0%, 20%, 40%, 60%, and 80% of the step cycle. The smaller upper subplots show of local dynamic stability for fallers (red) and nonfallers (blue) together with values. (b) of the log-median for fallers (red) and nonfallers (blue) defined by the state space reconstruction Method 2 (delay coordinate embedding) for initial perturbation at 0%, 20%, 40%, 60%, and 80% of the step cycle. The smaller upper subplots show of local dynamic stability for fallers (red) and nonfallers (blue) together with values.
