The incidence of fractures after a kick, coupled with marked soft tissue trauma at the site of injury, suggests that the force of a kick from the hind limb of a horse is enormous. The goal of this study was to measure this force and to investigate whether the Tekscan F-SCAN in-shoe pressure measuring system is suitable for quantification of the impact strength of a kick from a horse. The system was tested in 6 horses that had undergone clinical examination and gait analysis. The sensor-shoe combination was attached to each hind foot and the horse was stimulated to kick against a wall. The F-SCAN system measured the maximum vertical and horizontal force (N), the main contact area (cm2) of the sole with the floor (stance phase limb) or wall (kicking limb) and the duration (sec) that the sole was in contact with the floor or wall. In addition, each kicking event was recorded with a video camera for subjective evaluation. The mean kicking force measured was lower than that recorded in horses trotting on a treadmill, where the forces exerted on one limb were similar to the horse's body weight. The results of this study indicate that the Tekscan F-SCAN system is not ideally suited to measure the force of a kick of a horse in vivo.
踢踹后骨折的发生率，再加上损伤部位明显的软组织创伤，表明马后肢踢踹的力量是巨大的。本研究的目的是测量这种力量，并研究Tekscan F-SCAN鞋内压力测量系统是否适用于量化马踢踹的冲击强度。该系统在6匹已经接受过临床检查和步态分析的马身上进行了测试。将传感器-鞋组合安装在每只后脚上，刺激马踢向墙壁。F-SCAN系统测量了最大垂直和水平力（牛顿）、鞋底与地面（站立期肢体）或墙壁（踢踹肢体）的主要接触面积（平方厘米）以及鞋底与地面或墙壁接触的持续时间（秒）。此外，用摄像机记录每次踢踹事件以进行主观评估。测得的平均踢踹力低于在跑步机上小跑的马所记录的力，在跑步机上一匹肢体施加的力与马的体重相似。本研究结果表明，Tekscan F-SCAN系统并非理想地适用于测量马在活体状态下踢踹的力量。
