Estimation of Quasi-Stiffness and Propulsive Work of the Human Ankle in the Stance Phase of Walking
Figure 2
Ankle quasi-stiffnesses (N.m/rad) in dorsi-flexion (top-left), dual-flexion (top-right), and plantar-flexion (bottom-left) phases, and propulsive work (J) in stance (bottom-tight) plotted against gait speed for subject 10 as an example.
The circles indicate the experimental value and the diamonds are the predictions of the general-form models of Table 2.
