Imbalances and altered kinetics of the hoof result in lameness in horses. Previously, studies have focused on the midstance phase of a gait, hence, available information on the impact phase is scarce. This study aimed to investigate the effect of hoof trimming on the fore and hindhooves at the impact phase of the walk. Our objective was to compare the kinetic variables of force (N), contact area (cm), contact pressure (kPa), and peak contact pressure (kPa) before and after hoof trimming. Nine Arabian horses were walked straight over a pressure plate to collect the above kinetic variables for both left and right fore and hindhooves. The impact phase was defined as the first contact of each hoof with the pressure plate, which was collected as the first frame of data. The signed rank test was used to determine the difference of each kinetic variable between pre and post trimming for each hoof. A statistical P-value <.05 was considered significant. Routine hoof trimming of the forehooves did not significantly change the hoof kinetic variables, except for an increase of 56% (P = .0391) for contact area (CA) after trimming of the right forehooves. For the left hindhooves, force increased by 35% (P = .019) and CA increased by 18% (P = .039) after trimming. The data revealed how hoof trimming may affect hoof kinetics at the impact phase of the walk for this group of horses and demonstrates the need for further research in other breeds and disciplines.
马蹄的不平衡和动力学改变会导致马跛行。以前的研究主要集中在步态的支撑阶段，因此，关于冲击阶段的信息很少。本研究旨在探讨马蹄修剪对马行走冲击阶段前蹄和后蹄的影响。我们的目的是比较修剪前后力（N）、接触面积（cm）、接触压力（kPa）和峰值接触压力（kPa）等动力学变量。9 匹阿拉伯马在压力板上直线行走，以收集左右前蹄和后蹄的上述动力学变量。冲击阶段被定义为每个马蹄与压力板的第一次接触，这被收集为第一组数据。使用符号秩检验来确定每个马蹄修剪前后每个动力学变量的差异。统计 P 值<.05 被认为具有显著性。常规的前马蹄修剪并没有显著改变马蹄的动力学变量，除了右前马蹄修剪后接触面积（CA）增加了 56%（P=.0391）。对于左后蹄，修剪后力增加了 35%（P=.019），CA 增加了 18%（P=.039）。这些数据揭示了马蹄修剪如何在行走的冲击阶段影响这组马的蹄动力学，并表明需要在其他品种和学科中进行进一步研究。
