Studie II: Shift of the CoM in growing dogs
3.11. Tables
Table 1: Symmetry indices (mean ± s.d.) of the vertical force parameters for all
dogs at the different ages. Perfect symmetry is given at SI=0. Physiological ranges
are up to 4% and 6% difference for the fore- and the hindlimbs, respectively
(Budsberg et al., 1993). Negative values indicate that the parameters were greater
for the right than the left limb; positive values indicate the reverse.
