an increasing trendP < 0.001
In the treatment groups, BBB score showed an increasing trend over time so that the 15 mM NAR-receiving group had the highest difference compared to the SCI group ( Fig. 2A ) group [interaction: F (20, 180) = 16.05, P < 0.001, times: F (5, 180) = 227, P < 0.001, groups: F (4, 180) = 226, P < 0.001]. 2) Inclined plane test Based on the results, sham group rats maintained a normal angle of stay on the inclined-planed device (55°) at the evaluated time intervals post-laminectomy which indicates no locomotor impairment after the surgery.
