Female animals show less injury-induced deficit than males in hind limb stride, support diagonal, and single stance after SCI. Temporal analysis of a variety of CatWalk parameters (as calculated according to a percent error of gender-specific baseline values), speed (a), couplings of a diagonal paw pair (b), support diagonal (%) (c), support four (%) (d), single stance (e), forelimb stride length (f), hind limb stride length (g), hind limb base of support (h), regularity index (%) (i), and hind limb swing (j), showed that females have less injury-induced deficit in stride length, support diagonal, and single stance than males. On other CatWalk parameters, similar post-SCI deficits in walking behavior were observed among genders. CatWalk analysis was performed before injury, three weeks after injury, and biweekly for 13 weeks after SCI. Weeks that showed a significant gender difference are shown by ^∗, ^∗∗, or ^∗∗∗.
