FIG. 5.

Multi-dimensional motion of sham mice. The steps of 12 sham-injured mice are fitted with the smallest mesh that contains 68.27% of the data resulting in a multi-dimensional model of healthy gait. Colored meshes represent stance phase and gray represents swing. (A) Sham mouse gait is consistent (small mesh volumes) with right/left symmetry. The forelimb base of support is narrower than the hindlimbs. (B) By introducing the third dimension of time (right hindlimb cycle time with initial contact at time 0), limb phasing and interlimb coordination can be observed. The fore- and hindlimb pairs are out of phase whereas the diagonal pairs are in phase.
