Cord Injury Score was used to assess pelvic limb gait, posture and nociception. This is a more refined scale than the MFS with a larger array of sub-categories, including gait assessment that parallels the Basso, Beattie, Bresnahan Scale. The TSCIS gait score ranges from 0 to 6 in each pelvic limb and correlates to the degree of limb protraction and weight bearing. The gait 220904-83-6 classifications include: no voluntary movement seen when the dog is supported ; intact limb protraction with no ground clearance ; intact limb protraction with inconsistent ground clearance ; intact protraction with ground clearance.75% of steps ; ambulatory with consistent ground clearance and significant paresis-ataxia that results in occasional falling ; ambulatory with consistent ground clearance and mild paresis-ataxia that does not result in falling ; and normal gait. Pelvic limb postural responses using the TSCIS were scored in each limb as absent, delayed, and present. Nociception was scored in each limb as absent, deep nociception only present, or both deep and superficial nociception present. For the clinical trial data, a strategy for analysis of data was developed a priori, including our decision to stratify the population based on SCI severity at admission. Baseline characteristics were compared among the 3 treatment groups to determine whether there was any evidence of differences among groups. Categorical variables were compared using chi-squared analysis and continuous or ordinal variables were compared using Kruskal-Wallis tests. The primary outcome for the trial was the TSCIS score on day 42. The TSCIS on day 3 was 29700-22-9 considered a secondary outcome. The association of TSCIS with treatment group and other individual variables was assessed using generalized linear modeling. Individual variables significantly associated with TSCIS were analyzed using multivariable generalized linear modeling using maximum likelihood estimating methods. Multiple comparisons among groups were adjusted using the method of Sidak. Model fit was assessed graphically using diagnostic plots of residuals. This study was designed as a large-scale clinical trial to evaluate MMP inhibition in a clinically relevant, naturally occurring canine SCI model. Using advanced technology to measure activity of MMP-
