Assessment of Local Dynamic Stability in Gait Based on Univariate and Multivariate Time Series
(a) Time series representing a movement in sagittal plane (red line: left ankle joint, blue line: left knee joint, and green line: left hip joint); (b–d) 3D projections of corresponding reconstructed trajectories for: (b) left ankle joint; (c) left knee joint; (d) left hip joint. Each of the examined joints is characterized by a specific shape of the trajectory.
