Figure 3From: Fractal time series analysis of postural stability in elderly and control subjectsEvolution of H S for anteroposterior (a), mediolateral (b), and resultant (c) displacement. Data are means and 95% confidence intervals. The x axes represent time in seconds, while the y axes represent the estimation of HS. The zero values on the x axes correspond to FC2, while the x coordinate of each data point corresponds to the centre of the data window.Back to article page
