Evaluation of the effect of changes in the horses' feet after routine trimming and shoeing on gait at the trot is needed improve routine foot care. Evaluate changes in foot conformation and gait after routine farriery. Correlate alterations in a horse's gait before and after routine hoof trimming and shoe application. Fifteen horses received routine hoof trimming and horseshoe application. Dorsal and lateral photographs of the right and left front feet and inertial gait analysis at the trot were completed before and after trimming and shoeing. Measurements were made of hoof photos using a calibrated system. Gait and hoof measurements before and after farrier intervention were compared. Hoof measurement changes in relation to gait changes before and after farrier intervention were analyzed for significant associations. Mean medial to lateral coronary band length (P = .02), lateral (P = .01) and medial (P = .03) coronary band height, dorsal hoof wall length (P = .0004), heel length (P = .0002), heel overhang length (P < .0001), palmar coronary band height (P = .01), and hoof angle (P = .03) in each foot were significantly different pre- and post- farrier intervention. There was no statistical difference in the total head and pelvis movement before and after farrier intervention. The difference in the pooled mean of heel length before and after intervention was correlated with difference in maximum head movement (P = .03.) Pooled mean differences for dorsal hoof wall length (P = .04), heel length and heel overhang length (P = .006) before and after trimming were correlated with differences in maximum pelvis movement. Pooled mean differences for heel length (P = .005) and hoof angle (P = .04) before and after trimming were correlated with difference in minimum pelvis movement. Change in hoof conformation due to routine hoof trimming and shoeing does not change the gait in non-lame horses; however, some hoof characteristics measurements are correlated with immediate change in stride parameters. Use of hoof measurements may assist farriers and veterinarians in applying routine hoof care. Further studies could help determine what hoof conformation changes may be helpful to treat lame horses.
需要评估马在常规修剪和钉蹄后脚部的变化对小跑步态的影响，以改善常规足部护理。评估常规蹄铁术后脚部形态和步态的变化。将马在常规蹄部修剪和蹄铁应用前后的步态变化进行相关联。15 匹马接受了常规蹄部修剪和马蹄铁应用。在修剪和钉蹄前后，完成了右前和左前脚的背侧和侧位照片以及惯性步态分析。使用校准系统对马蹄照片进行测量。比较了蹄铁干预前后的步态和蹄部测量值。分析了蹄铁干预前后与步态变化相关的蹄部测量值变化之间的显著关联。每只脚的内侧到外侧冠状带长度（P =.02）、外侧（P =.01）和内侧（P =.03）冠状带高度、背侧蹄壁长度（P =.0004）、蹄跟长度（P =.0002）、蹄跟悬垂长度（P <.0001）、掌侧冠状带高度（P =.01）和蹄角度（P =.03）均在干预前后有显著差异。在蹄铁干预前后，总头部和骨盆运动没有统计学差异。干预前后蹄跟长度的平均差值与最大头部运动的差值呈相关性（P =.03）。干预前后背侧蹄壁长度（P =.04）、蹄跟长度和蹄跟悬垂长度（P =.006）的平均差值与最大骨盆运动的差值呈相关性。干预前后蹄跟长度（P =.005）和蹄角度（P =.04）的平均差值与最小骨盆运动的差值呈相关性。由于常规蹄部修剪和钉蹄，蹄部形态的变化不会改变非跛行马的步态；然而，一些蹄部特征测量值与步幅参数的立即变化相关。使用蹄部测量值可能有助于蹄铁工和兽医进行常规蹄部护理。进一步的研究可以帮助确定哪些蹄部形态变化可能有助于治疗跛行马。
