In many Western European countries rocker-toed shoes are applied routinely in sound horses. This is in contrast to most Anglo-Saxon countries where rocker-toed shoes are used almost exclusively for corrective or orthopaedic shoeing. The purposes of rocker-toed shoes are to hasten or facilitate breakover, or to encourage breakover to occur at the centre of the toe. This study compares the biomechanical effects of rocker-toed shoes with standard flat shoes in twelve sound Dutch warmblood horses, using a modified CODA-3 gait analysis system and a force plate. The variables analysed were speed of breakover, the moment of force in the coffin joint which is related to the 'ease' of breakover, the flight arc of the hoof in the sagittal and horizontal planes and some more general linear, temporal and angular stride characteristics. No differences between rocker-toed shoes and standard flat shoes were found with respect to the duration or ease of breakover or the proximity of breakover to the centre of the toe. It is concluded that rocker-toed shoes do not influence the stride characteristics of sound Dutch warmblood horses, and the findings of this study showed no objective grounds for the use of rocker-toed shoes in sound horses.
在许多西欧国家，蹄尖翘曲鞋通常应用于健康马匹。这与大多数盎格鲁 - 撒克逊国家形成对比，在这些国家，蹄尖翘曲鞋几乎仅用于矫正或矫形蹄铁。蹄尖翘曲鞋的目的是加速或促进蹄趾离地，或促使蹄趾离地发生在蹄尖中央。本研究使用改良的CODA - 3步态分析系统和测力板，比较了蹄尖翘曲鞋与标准平底鞋对12匹健康荷兰温血马的生物力学影响。分析的变量包括蹄趾离地速度、与蹄趾离地“难易程度”相关的蹄关节力矩、蹄在矢状面和水平面的飞行弧度以及一些更一般的线性、时间和角度步幅特征。在蹄趾离地的持续时间或难易程度，以及蹄趾离地与蹄尖中央的接近程度方面，未发现蹄尖翘曲鞋与标准平底鞋之间存在差异。得出的结论是，蹄尖翘曲鞋不会影响健康荷兰温血马的步幅特征，本研究结果表明，在健康马匹中使用蹄尖翘曲鞋没有客观依据。
