Footprint test. a Representative footprint analysis before spinal cord injury (SCI) (intact), 0 weeks post-transductin (WPT), and 6 WPT in the Mock and ZFP groups. These photographs show the walking pattern of rats on a narrow corridor. b Schematic used for quantifying stride length, step width, foot length, toe spread, and stride angle. c Graphs of all footprint parameters. Footprints parameters including step length, toe spread, foot length, and paw area improved significantly in the Zfp521 group. Data are plotted as mean ± SD. n = 4 per group. Data were analyzed by ANOVA and Mann-Whitney U test as post hoc. *p < 0.05, **p < 0.01, and ***p < 0.001
