Figure 4. Motor deficits in aged HdhQ111/+ mice.

Figure 4

HdhQ111/+ and Hdh+/+ mice at 46 weeks of age were tested on an automated CatWalk system (A-D) and for their ability to descend a vertical pole (E,F). HdhQ111/+ mice showed reduced Right by Left hindlimb stride length (A,B), a decreased cruciate step pattern frequency of pattern left front-right front-left hind-right hind (C,D) and an increased time to descend a vertical pole (total duration being the time taken to turn at the top of the pole and descend to the bottom). . For the CatWalk N=10 per sex and genotype; for the pole descent, males N=8 Hdh+/+, N=9 HdhQ111/+, females N=10 per genotype. Plotted are Tukey box-whisker graphs. All tests showed a significant genotype p value in a 2-way ANOVA. * Adjusted p value (p<0.05) following multiple testing correction.
