A link between surface characteristics and injury has been identified in equine disciplines. Maintenance procedures are reported to affect surface characteristics and could influence horse movement. The study investigated limb and hoof movement on a synthetic surface following two different preparations (harrowing and rolling). Nine horses were recorded using infrared cameras and retro-reflective markers at walk, trot and canter on two surface preparations in a cross-over design. Hoof rotation and displacement, metacarpophalangeal joint (MCPJ) extension and third metacarpal (McIII) inclination (roll, pitch and yaw) were analysed using a general linear model. Surface hardness and traction were also measured. No differences in hoof rotations or hoof displacements were found between preparations. However, following harrowing, greater (P<0.05) MCPJ extension at mid-stance and greater (P<0.05) McIII adduction at impact was found when gait was grouped. Hardness and traction were statistically similar for both preparations. Alteration to the surface cushion appears to be sufficient to produce subtle changes in stride characteristics.
在马术领域，已确定表面特性与损伤之间存在关联。据报道，维护程序会影响表面特性，并可能影响马匹的运动。该研究调查了在两种不同处理方式（耙地和碾压）后的合成表面上的肢体和蹄部运动。采用交叉设计，使用红外摄像机和反光标记对9匹马在两种表面处理方式下的行走、小跑和疾驰进行了记录。使用一般线性模型分析了蹄部旋转和位移、掌指关节（MCPJ）伸展以及第三掌骨（McIII）倾斜度（滚动、俯仰和偏航）。还测量了表面硬度和牵引力。两种处理方式之间未发现蹄部旋转或蹄部位移的差异。然而，耙地后，当步态分组时，发现站立中期掌指关节伸展更大（P<0.05），着地时第三掌骨内收更大（P<0.05）。两种处理方式的硬度和牵引力在统计学上相似。表面缓冲的改变似乎足以使步幅特征产生细微变化。
