FIG. 2.

Kinematic evaluations of hindlimb function after traumatic spinal cord contusion. Kinematic analyses from different injury groups as in Figure 1 were pooled and plotted as mean±standard error of the mean, n=3–5 rats. There were no statistically significant differences between groups for swing length (A) or swing velocity (C). The step cycle duration (B) for moderate injury animals was significantly different from mild and sham injury animals (*; p<0.05). Middle swing foot position relative to hip (D) revealed a graded response to injury with all injury groups having negative positions. Severe injury animals had the most negative positions, while sham injury animals had positive positions. Severe injury positions were significantly different from those of mild and sham injury positions while moderate injury positions were significantly different from those of sham injury positions (*; p<0.05).
