Conventional shoeing restricts heel movement, which may have a negative effect on the orthopaedic health of the horse. A randomised crossover experimental study using noninvasive techniques was performed to compare the mediolateral heel movement in barefoot horses, horses shod with a conventional toe clipped shoe and with a new type of shoe with a split toe. In eight horses, 16 forelimbs were tested barefoot, shod with a conventional shoe and with the split-toe (ST) shoe, in random order. A displacement sensor was secured on the heels and measurements were collected continuously at a frequency of 679Hz while horses were exercised on a treadmill at the walk (1.8m/s), trot (3.5m/s) and canter (8m/s). Differences in heel movement between the conditions were analysed using a generalised estimating equations approach. The conventional shoe was associated with significantly less heel expansion compared with the ST shoe and barefoot situation in all gaits (P≤0.001). Heel expansion with the ST shoe was not significantly different from the barefoot condition. For all gaits, shoeing was associated with a significant reduction in heel contraction compared with the barefoot situation (P≤0.038), except for the heel contraction at the canter using a conventional shoe. In conclusion, the heel expansion with the ST shoe did not differ significantly from when the horse was barefoot, in contrast with the significant restriction of the heel movement when a conventional shoe was used.
传统蹄铁限制了马蹄后跟的活动，这可能会对马的骨科健康产生负面影响。进行了一项使用非侵入性技术的随机交叉实验研究，以比较裸足马、穿着传统削趾蹄铁的马和穿着新型分趾蹄铁的马的内外侧后跟运动。在八匹马中，对16个前肢依次进行了裸足、穿着传统蹄铁和分趾蹄铁的测试。在马蹄后跟固定一个位移传感器，当马在跑步机上以慢步（1.8米/秒）、快步（3.5米/秒）和跑步（8米/秒）运动时，以679赫兹的频率连续收集测量数据。使用广义估计方程方法分析不同条件下马蹄后跟运动的差异。在所有步态中，与分趾蹄铁和裸足情况相比，传统蹄铁导致的马蹄后跟扩张明显更少（P≤0.001）。分趾蹄铁情况下的马蹄后跟扩张与裸足情况没有显著差异。对于所有步态，与裸足情况相比，钉蹄铁会导致马蹄后跟收缩显著减少（P≤0.038），但使用传统蹄铁在跑步时的马蹄后跟收缩情况除外。总之，分趾蹄铁导致的马蹄后跟扩张与马裸足时没有显著差异，而使用传统蹄铁时马蹄后跟运动受到显著限制。
