Resting time 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. Resting time differed significantly between groups on Day 1 (a), Day 14 (c) and Day 28 (e), as determined by ANOVA with Tukey’s multiple comparisons, and on Day 7 (b) and Day 21 (d) 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. ** = P<0.01.
