Low rearing scores of rats (n = 6 per group) subjected to laminectomy using conventional (CONV-LAM) or motorized dental burr assisted (DBA-LAM) technique at, or subjected to spinal cord injury induced using conventional (CONV-SCI) or dental burr assisted (DBA-SCI) technique during the study period. Low rearing scores differed significantly between groups on Day 7 (b), 14 (c), 21(d), as determined by ANOVA with Tukey’s multiple comparisons, and on Day 28 (e) postoperatively, as determined by Kruskal-Wallis test with Dunn’s multiple comparisons. Data are presented as scatter plot with each dot representing one individual animal, the horizontal line the mean and the whiskers the standard deviation.
