In the present study, we used a pressure plate to investigate the ground reaction forces oflimbs and the vertical force distribution within the paws of dogs with coxarthrosis. We included23 sound dogs and 23 dogs with hip osteoarthrosis. The dogs walked over a pressure plateand the peak vertical force and vertical impulse (expressed as a percentage of the total verticalforce or vertical impulse respectively of all limbs), time of occurrence of the peak vertical forceas a percent of the stance phase duration were evaluated, as well for the entire limb as withinthe paws (where the paws were divided into four quadrants). The group of dogs with hiposteoarthrosis presented a lower peak vertical force in the lame hind limb than in the othersand transferred the weight to the caudal quadrants of the front limbs. The vertical impulse waslower in the lame limb compared to the other legs and was counterbalanced through higherloading of the caudal quadrants in all unaffected limbs. The time of occurrence of the peakvertical force was reached later in the lame limb than in the contralateral limb and the sounddogs, specifically in the caudomedial quadrant. In conclusion, we found complexcompensatory effects of lameness in the hind limb, and this methodology was useful to definethe vertical force distribution within the paws of dogs.
