Analysis of Human Standing Balance by Largest Lyapunov Exponent

Figure 2

The raw data of a subject: (a) stimulus is in the 0 Hz, (b) stimulus is in the 0.8 Hz. The dynamical data is from a typical subject and (a) shows the data when the subject is standing under stimulus of 0 Hz frequency; (b) shows the data when the subject is standing under stimulus of 0.8 Hz frequency.
