Analysis of Human Standing Balance by Largest Lyapunov Exponent

Figure 4

Comparison of quiet standing LLE_COP and passive standing LLE_COP. The vertical axis represents the value LLE_COP; the horizontal axis represents the sample number of subjects. Dark bar shows LLE_COP values in Table 1 (at 0 Hz platform motion, static sway data of the body without stimulus), while light bar shows LLE_COP values in Table 2 (the data of passive sway body under 0.8 Hz stimulus).
