Studie II: Shift of the CoM in growing dogs Fig. 2: Vertical force curves of the fore- and the hindlimbs time-normalized to the stance duration of the forelimbs. Plotted are the means from the six dogs, error bars indicate standard deviation. Note, the decrease of the hindlimb’s stance time relative to that of the forelimbs and the increasing force difference between fore- and hindlimbs. *Two dogs were studied at PW20. 68
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.
