FIG. 4.

Hind- or forepaw distance from the center of body on the rostrocaudal axis while walking at a treadmill speed of 6.0 cm/sec. Reference lines for baseline (grand mean±one standard error of the mean) are included. Note that both hind- and forepaw distances were increased at the severe and very severe impact levels (125 kDyn/mild, 175 kDyn/moderate, 200 kDyn/severe, and 225 kDyn/very severe; *p<0.05, compared to baseline; ^♦p<0.05, compared to 4-week mild injury; repeated-measures two-way analysis of variance with Student-Newman-Keuls' post-hoc test; n=4–14).
