From: Limb phase flexibility in walking: a test case in the squirrel monkey (Saimiri sciureus)
Limb phase data from walking steps on each substrate type in our sample of Saimiri sciureus. Box plots indicate maximum, minimum, median and quartile values for each substrate. LS: lateral sequence, DS: diagonal sequence, LC: lateral couplet, DC: diagonal couplet. No gaits were observed within the limb phase range of LSDC gaits in these animals, no animal has yet been recorded using a DSLC gait. On the footfall diagrams arrows indicate the direction of weight transfer. The direction of the arrow moving from the right hind foot ‘RH’ indicates sequence (LS or DS), direction of the short arrow indicates couplet type (LC or DC). Arrow length indicates whether the delay between touchdowns is short (less than 25% of a stride) or long (greater than 25% of a stride)
