Abstract：
Hoof care providers are pivotal for implementing biomechanical optimizations of the musculoskeletal system in the horse. Regular visits allow for the collection of longitudinal, quantitative information (\"normal ranges\"). Changes in movement symmetry, e.g., after shoeing, are indicative of alterations in weight-bearing and push-off force production. Ten Warmblood show jumping horses (7-13 years; 7 geldings, 3 mares) underwent forelimb re-shoeing with rolled rocker shoes, one limb at a time (\"limb-by-limb\"). Movement symmetry was measured with inertial sensors attached to the head, withers, and pelvis during straight-line trot and lunging. Normalized differences pre/post re-shoeing were compared to published test-retest repeatability values. Mixed-model analysis with random factors horse and limb within horse and fixed factors surface and exercise direction evaluated movement symmetry changes (p < 0.05, Bonferroni correction). Withers movement indicated increased forelimb push-off with the re-shod limb on the inside of the circle and reduced weight-bearing with the re-shod limb and the ipsilateral hind limb on hard ground compared to soft ground. Movement symmetry measurements indicate that a rolled rocker shoe allows for increased push-off on soft ground in trot in a circle. Similar studies should study different types of shoes for improved practically relevant knowledge about shoeing mechanics, working towards evidence-based preventative shoeing.
摘要：
蹄护理提供者对于实施马的肌肉骨骼系统的生物力学优化至关重要。定期访问允许收集纵向，定量信息(“正常范围”)。运动对称性的变化，例如，鞋后，表明承重力和推力产生的变化。十种热血表演跳马（7-13岁；7个geldings，3只母马）用轧制摇杆鞋进行前肢换鞋，一次一条肢体（“逐个肢体”）。运动对称性是用连接到头部的惯性传感器测量的，枯萎,和骨盆在直线小跑和跳跃时。将返鞋前/返鞋后的归一化差异与已发布的测试-重新测试可重复性值进行比较。用随机因素马和马内肢体和固定因素的混合模型分析表面和运动方向评估运动对称性的变化（p<0.05，Bonferroni校正）。与柔软的地面相比，纤细的运动表明前肢在圆内侧的情况下前肢的推脱增加，而在硬地面上的后肢和同侧后肢的负重减少。运动对称性测量表明，滚动的摇杆靴允许在圆的小跑中在软地面上增加推脱。类似的研究应该研究不同类型的鞋子，以改善有关鞋子力学的实际相关知识，致力于以证据为基础的预防性穿鞋。
