Figure 1.
Comparison of footfall sequence in primate (baboon, above) and nonprimate (cat, below).
Footfall sequence is depicted numerically, beginning with the right hind limb in each animal. The primate is walking in diagonal sequence (RH-LF-LH-RF), and the nonprimate is walking in lateral sequence (RH-RF-LH-LF), where R = right, L = left, H = hind limb, and F = forelimb. Images from [2].

Sample.
Figure 2.
Representative footfall sequences in Participant 1 (Family “A”).
Above, lateral sequence, diagonal couplets (limb phase = 0.36, mean duty factor = 0.75); below, lateral sequence, lateral couplets (limb phase = 0.20, mean duty factor = 0.61) Black bars represent the period of substrate contact for each limb (LH: left hind limb; LF: left forelimb; RF: right forelimb; RH: right hind limb).

Frequencies of gait type in Family “A”.
a) Total gait frequencies, and b) gait frequencies by participant. LS = Lateral sequence, DS = Diagonal sequence, LC = Lateral couplets, DC = Diagonal couplets, SF = Singlefoot.

Box and whiskers plots of limb phases by participant (Family “A”).
Lines represent the median, boxes represent the interquartile range, whiskers are 1.5x the interquartile range, circles are outliers and asterisks extreme outliers. Abbreviations as in Fig. 3.

Participants 1–5 are from Family “A”; additional cases are represented by Participants 6 and 7 (see Table 1). Abbreviations as in Fig. 3.
