Symmetry Analysis of Gait between Left and Right Limb Using Cross-Fuzzy Entropy

Table 1

Summary of the classification results for PD patients and CO subjects using C-FuzzyEn(), C-SampleEn(), and ASI feature calculated from the left and right stride interval time series. The results were obtained by using RBF-kernel-based SVM classifier and the LOO cross-validation method. TP, TN, FP, and FN denote true positives, true negatives, false positives, and false negatives, respectively.
