Figure 2From: A comparative study on approximate entropy measure and poincaré plot indexes of minimum foot clearance variability in the elderly during walkingMFC Poincaré plots. Top panels show MFC time series from a healthy elderly subject (A) and its corresponding Poincaré plot (B). Bottom panels show MFC time series from an elderly subject with balance problem (C) and its corresponding Poincaré plot (D).Back to article page
