FIG. 5.

Hindpaw stance width and forepaw normalized stance width 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 hindpaw stance width was increased at moderate, severe, and very severe impacts. Additionally, moderate, severe, and very severe impacts were all increased above mild impact. Normalized forepaw stance widths were decreased at all impact intensities (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).
