Fig. 1From: On the use of approximate entropy and sample entropy with centre of pressure time-seriesApproximate Entropy (ApEn) and Sample Entropy (SampEn) as a function of m, r and N for the anterior-posterior (AP) component of the centre of pressure displacement during quiet standing: a) ApEn for N = 600, b) ApEn for N = 1200, c) SampEn for N = 600, and d) SampEn for N = 1200Back to article page
