FIG. 3.

Hind- or forepaw surface area utilized at peak stance while walking at a treadmill speeds of 6.0 cm/sec. Reference lines for baseline grand mean±one standard error of the mean are included. Note that both fore- and hindpaw surface areas were decreased at peak stance at all 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 125 kDyn impact; repeated-measures two-way analysis of variance with Student-Newman-Keuls' post-hoc test; n=4–14).
