Ang-(1–7) improved the motor function of rats after SCI. a Basso, Beattie and Bresnahan (BBB) scores (n = 6). b Inclined plane test scores (n = 6). c Schematic diagram of electrophysiological motor evoked potential detection. d–f Motor-evoked potential (MEP) recordings quantification of Amplitude and Latency in each group on the 28th day post-surgery (n = 6). g Footprints and maximum contact area of rats in each group on the 28th day post-surgery (n = 6). h Footfall patterns of rats in each group on the 28th day post-surgery (n = 6). i–j Comparison of Regularity index and Stride length between each group of rats (n = 6). Error bars indicated the mean ± SD for three separate experiments. ns nonsignificant, P > 0.05; * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001. In a–b, two-way ANOVA followed by Bonferroni’s post hoc tests. In c-j, one-way ANOVA followed by Tukey's Post Hoc test
