Lets break down the concept of Hoof Balance!
As our industry shifts towards evidence-based practices, the quantifiction of hoof balance emerges as a topic of discussion for maintaining soundness and increasing performance. Hoof balance is a continuous debate within the farriery community, with new research adding complexity to the understanding of good practice. Achieving the optimum balance, where the horse's weight is evenly distributed over the hoof, remains a fundamental goal.
A horse's gait comprises stance and swing phases, with hoof balance intricately linked to load distribution during stance. While the swing phase is less influenced by farriery, farriers do play a large role in the stance phase. This is the moment the hoof makes contact with the ground through the moment they break over. Farriers must recognize the dynamic nature of these phases and their impact on the horse's musculoskeletal system.
Traditionally, farriers rely on visual assessments to determine hoof impacts and loadings. However, modern technologies, such as pressure plate systems, provide objective data on how hoof balance affects load distribution throughout the stance phases.
Research is relatively conclusive on dorso-palmar balance. It significantly influences biomechanics at each stage of the stance (Van Heel et al., 2004; Clayton et al., 1990), From toe-first or heel/flat landings to the strain on flexor structures at midstance and breakover.
Medio-lateral balance remains less conclusive, studies emphasize its importance in preventing uneven loading, reducing the risk of injuries (Wilson et al., 1998), however new measurements, like impulse forces, add complexity to understanding when and where balance matters most. Limb conformation adds even more complexities to how the hoof is loaded and therefore its shape..
There is far more research to be done on the topic of hoof balance, but in the meantime, you can take a deeper dive into these theories here:
