From: A perceptual map for gait symmetry quantification and pathology detection
Asymmetry maps for subject #S05 for, respectively (from left to right) the normal gait and the left and right simulated LLD (cases A, B and C). The L2, L1, Linf, Lmod, Lrad and Lmoy distances are presented. For these cases, the ASI are, respectively 20.6/32.8/32.8, 22.3/35.6/30.9, 16.9/29.8/23.9, 20.9/30.3/29.2, 38.2/63.3/62.0 and 35.4/64.0/48.0. With right LLD (case C), the asymmetry of arm swing is clearly noticeable for the right LLD with the L2 (see the circled regions), L1 and Lmod distances. As expected, leg motion asymmetries are also visible for the left and right LLD. ASI curves are also presented (in which the Y axis shows the biggest mirrored difference (located on a horizontal line) as a function of the vertical distance from the top head of the subject (X axis) (see text)
