Examining Human Unipedal Quiet Stance: Characterizing Control through Jerk

Figure 9

Examples of rms jerk data are plotted as a function of time scale along with the corresponding log-log plot for better visual suggestion of scaling behavior. In general, each depiction is fairly typical of all of the data in terms bulk features concerning shape. A particular range of time is denoted “interesting” in which scaling behavior needs to be explored for each data set. Linear regression of these profiles does not indicate common scaling parameters for such fine-grained features. (a) A-P movement data. (b) log-log plot of values in (a). (c) M-L movement data. (d) log-log plot of values in c.
