Phase Space Reconstruction and Estimation of the Largest Lyapunov Exponent for Gait Kinematic Data.

The authors describe an example of application of nonlinear time series analysis directed at identifying the presence of deterministic chaos in human motion data by means of the largest Lyapunov exponent. The method was previously verified on the basis of a time series constructed from the numerical solutions of both the Lorenz and the Rössler nonlinear dynamical systems. [ABSTRACT FROM AUTHOR]
