Effect of the treatment on symmetry indices values for kinetic data during walking. a Symmetry indices (SI) for Peak vertical force (PVF); b SI for Vertical impulse (VI). Assessments were made 24 and 48 h initial and second surgery (baseline) and 6, 24, 30, 48, 54, and 72 h after surgery. The difference between this average baseline value and the measured value were calculated at each time point in the analysis. Line graphs showing the mean difference ± SD in control group and extended release formulation of buprenorphine HCL (ER-Bup) group at various time points after onychectomy (n = 4). Orange solid line is control group, blue dotted line is ER-Bup group. Negative value of SI means the cat put less weight on operated limb after surgery.* indicates significant difference between groups (<0.05)
