Background Persistent postural perceptual dizziness (PPPD) is a common cause of chronic and imbalance. Emerging evidence suggests that changes in quantitative measures control may help identify individuals with PPPD, however, traditional linear metrics sway have yielded inconsistent results. Methodologies to examine the temporal structure sway, including recurrent quantification analysis (RQA),...

The Shannon entropy of a time series is a standard measure to assess the complexity of a dynamical process and can be used to quantify transitions between different dynamical regimes. An alternative way of quantifying complexity is based on state recurrences, such as those available in recurrence quantification analysis. Although varying definitions for recurrence-based entropies have been sugg...
