Appropriate hoof preparation and symmetry are linked to the wellbeing of the horse. Previous studies have shown the efficacy of the pressure plates (PP) in delivering objective biomechanical analysis. We aimed to assess the effect of hoof trimming on hoof biomechanics using a PP. Nine clinically sound Arabian horses were walked across the PP while foot strike was recorded by a digital camera. Kinetic and kinematic parameters were recorded before and after trimming. P values ≤ 0.05 were considered significant. Vertical force (P = 0.026) and contact pressure (P = 0.006), increased after trimming. Stance phase duration (P = 0.006), swing phase duration (P = 0.023) and gait cycle duration (P = 0.007), decreased significantly post-trimming. The observed changes in kinetic and kinematic parameters are related to hoof trimming. The reported results underline the importance of the farriery practice and its effect on hoof biomechanics, which should be considered by farriers and veterinarians.
