The center of pressure (COP) is recognized as a valuable tool for the assessment of orthopedic and neurologic disorders in humans. Relatively few studies are available in veterinary medicine, particularly concerning the COP in the individual paw. This study assessed the dynamic paw COP parameters during the stance phase of dogs with cox- or cubarthrosis (20 dogs each), as well as of 20 sound dogs. Data were obtained by walking over a pressure platform and analyzed within the diseased groups in comparison to the control group. Both diseased groups showed significant differences between the affected and non-affected limbs, but also in comparison to the reference limbs of sound animals. For coxathrosis, the primary increase was in the medio-lateral COP displacement and the COP area in both hind limbs. For cubarthrosis, the most prominent changes were an increase in the medio-lateral COP displacement in the ipsilateral hind limb and in the cranio-caudal COP displacement in the lame limb. Additionally, the COP area increased in both hind limbs. This can reflect a compensatory redistribution of the body mass as well as compensatory changes of body balance.

与有病的犬相比，临床上有声犬的爪子的压力中心。

压力中心（COP）被认为是评估人类骨科和神经系统疾病的宝贵工具。兽医学方面的研究相对较少，尤其是有关单个爪中COP的研究。这项研究评估了患有克斯氏或肺病的犬（每只20只）和20只健全犬在站立阶段的动态爪COP参数。通过在压力平台上行走获得数据，并与对照组比较在患病组中进行分析。两个患病组均显示患肢和非患肢之间有显着差异，而且与健全动物的参考肢相比也有显着差异。对于髋关节炎，主要的增加是两个后肢的中外侧COP位移和COP面积。对于囊肿，最显着的变化是同侧后肢的中外侧COP位移增加和me肢的颅尾COP位移增加。此外，两个后肢的COP面积均增加。这可以反映体重的补偿性重新分配以及身体平衡的补偿性变化。
