Abstract

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.
