The biomechanical aspects of the postural adjustments accompanying limb lifting were studied. A mechanical model of a quadruped animal is proposed. It consists of 10 links for dogs and 12 links for cats. Good agreement between experimental and model data is shown to exist so that the rigid body mechanical model is suitable for use in the analysis of postural adjustment.

The main result of this study is the finding that the biomechanical model can be used to determine correlations between all kinds of body movements involving a shift in the center of gravity, and the support pressure pattern. It can be used to derive all possible kinds of information about the movement kinematics from the vertical pressure force components usually recorded in experiments. Two different cases are investigated: the one corresponding to static conditions and the other to dynamic ones. For the static case, a clear geometrical interpretation of the connection between pressure force patterns and the center of gravity (CG) shift is presented. It is shown that the kinematics in themselves do not set any limits on the type of support pressure pattern.
