TPL refers to total path length or the total distance traveled by the center‐of‐pressure. StdAP and StdML refer to the standard deviation of the variability about the mean location in the anterior‐posterior and medial‐lateral directions respectively. DFA‐AP and DFA‐ML refer to the degree of self‐similarity across varying windows of time for the anterior‐posterior and medial‐lateral time series respectively.
