Figure 4.
Comparison of run characteristics and kinetic, temporal and spatial parameters between C57BL/6N and DBA/2 mice at P42. (a) DBA/2 mice showed a significant increase in the average speed and cadence, but no difference in the number of steps compared to C57BL/6N mice. (b,c) DBA/2 mice showed an increase in the body speed (b) and swing speed (c) of all paws compared to C57BL/6N mice. (d) DBA/2 mice showed a significant decrease in the stand time of LF and RF paws. (e) DBA/2 mice showed a significant decrease in the swing time of all paws. (f) DBA/2 mice showed a significant decrease in the step cycle of LF, RF and RH paws. (g) DBA/2 mice showed a significant decrease in the maximum contact at (%) of both LF and RF paws compared to C57BL/6N mice. (h,i) DBA/2 mice showed an increase in the print area of all paws (h) and a decrease in the maximum intensity of the RH paw compared to C57BL/6N mice. (i). Two-way ANOVA followed by Bonferroni post hoc test, *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001. A red rectangle indicates a significant difference between sexes within a strain (see Supplementary Table S1). Error bars indicate the standard error of the mean (SEM). RF right front, LF left front, RH right hind, LH left hind.
