The ground reaction force patterns from 20 clinically sound Dutch Warmblood horses (Group A) were recorded at the normal walk. The data from four to 10 stance phases of each limb were computer averaged after normalisation to the animal's body mass and to the stance time. This analysis method allowed comparison of data from left and right fore- and hindlimbs within and between horses. The left-to-right symmetry in the reaction force peaks of contralateral limbs of one horse exceeded 90 per cent. The time in the stance phase at which the peaks occur were even more symmetrically distributed. A characteristic force-force diagram was constructed by plotting the longitudinal horizontal and the vertical ground reaction forces against each other; in this way the symmetry of loading of contralateral fore- and hindlimbs could be interpreted easily. Force plate tracings were obtained from eight horses (Group B) in three successive years. The similarity of the tracings from a sound, well-trained horse over that period was better than the differences between horses of the same breed.
记录了20匹临床健康的荷兰温血马（A组）在正常行走时的地面反作用力模式。在将数据标准化为动物体重和站立时间后，对每个肢体4至10个站立阶段的数据进行了计算机平均处理。这种分析方法允许比较同一匹马内以及不同匹马之间左、右前肢和后肢的数据。一匹马的对侧肢体反作用力峰值的左右对称性超过90%。峰值出现时的站立阶段时间分布更加对称。通过相互绘制纵向水平和垂直地面反作用力构建了一个特征力-力图；通过这种方式，可以轻松解释对侧前肢和后肢加载的对称性。连续三年从八匹马（B组）获得了测力板记录。在那段时间里，一匹健康、训练有素的马的记录相似性优于同一品种马匹之间的差异。
