Fig. 4From: On the use of approximate entropy and sample entropy with centre of pressure time-seriesSample entropy (SampEn) mean value (marker) and 95% confidence interval (error lines) by group and testing condition for selected parameter combinations: a) SampEnAP(m = 2, r = 0.1, N = 1200), b) SampEnAP(m = 2, r = 0.3, N = 1200), and c) SampEnAP(m = 2, r = 0.5, N = 1200). Conditions (vision-surface): OR open-rigid, CR closed-rigid, OF open-foam, CF closed-foamBack to article page
