Assessment of Local Dynamic Stability in Gait Based on Univariate and Multivariate Time Series

Figure 7

Box plots for computed in MultiFNN state space for different scenarios: (a) Normal; (b) Perturbation; (c) Faster; (d) Slower; (e) Up; (f) Down. All values are positive but smaller than the corresponding values: locally unstable behavior is gradually attenuated by the locomotor system. The platform jerks seem to have no effect. The walking speed seems to affect the knee joint primarily, while the platform inclination seems to have the greatest impact on the hip joint.
