Force plate analysis assesses gait symmetry and limb loading. However, as previously described, individual and breed variability (body size and conformation) is related to breeding, body conformation, and size. This prospective study aimed to evaluate the influence of morphometric measures on the speed (V), peak of vertical force (PVF), vertical impulse (VI), and stance time (ST) in healthy dolichomorph and mesomorph dogs and their combined effect on and interactions with V, PVF, VI, and ST in the same morphological types. Fifty dogs were enrolled in the current study, and specific morphometric measurements were recorded for each dog. A force platform was used to record the ground reaction forces (GFRs), including PVF and VI. Multiple linear regression models were used for the study purposes. According to our results, GFRs are influenced by morphometric measures (body weight, withers height, and speed) not so much as a single contribution, but by the interaction between them. It is not possible to compare GFRs in dogs that do not belong to the same breed. However, the subjective variabilities make this comparison difficult and poorly reliable. According to the author, the comparison should be made between canine morphological types rather than breeds.
测力板分析可评估步态对称性和肢体负荷。然而，如前所述，个体和品种差异（体型和形态）与繁殖、身体形态和大小有关。这项前瞻性研究旨在评估形态测量指标对健康的细长型和中胚层型犬的速度（V）、垂直力峰值（PVF）、垂直冲量（VI）和站立时间（ST）的影响，以及它们在相同形态类型中对V、PVF、VI和ST的综合影响及相互作用。本研究纳入了50只犬，并记录了每只犬的特定形态测量数据。使用测力平台记录地面反作用力（GFRs），包括PVF和VI。本研究采用多元线性回归模型。根据我们的结果，GFRs受形态测量指标（体重、肩高和速度）的影响，并非单一因素起作用，而是它们之间的相互作用。无法对不同品种的犬的GFRs进行比较。然而，主观差异使得这种比较困难且可靠性差。根据作者的观点，应该在犬的形态类型之间进行比较，而不是品种之间。
