A technique for assessing hoof function in the horse.

This study explores a method that uses foil strain gauges to measure the changes in a horse’s hoof wall as it bears weight, specifically looking at the difference between shod (shoed) and unshod (unshoed) horses. The researchers concluded that the method can reliably detect hoof movement and found that traditional iron horseshoes limit the flexibility and spread of the hoof wall, without significant impact on the heel expansion.

Methodology

• The authors of the research paper utilised foil strain gauges applied directly to the horse’s hoof wall. This is an innovative approach, as strain gauges, typically used to measure the deformation or strain of an object, are not commonly used in animal locomotion studies.
• Through the use of certain measuring equipment, the researchers were able to monitor a horse’s hoof while it was bearing weight. This monitoring included looking at changes in the shape of the horse’s hoof. The addition of this measuring technique allowed for an in-depth understanding of the hoof’s function in a variety of conditions.

Findings

• The results showed that the foil strain gauges were effective at detecting movement in the hoof. Moreover, the results were reproducible which showcases the reliability of the system they used.
• The study compared hoof function in both shod (wearing horseshoes) and unshod horses. A key difference was found: a conventional nailed-on iron shoe restricts the hoof’s natural flexion and spreading at the ground surface. This could potentially limit the horse’s natural ability to adapt to different surfaces and may affect the health of the horse’s hoof in the long run.
• Importantly, while the use of conventional iron horseshoes was found to affect the hoof wall’s function, it was found to have minimal effect on the expansion of the horse’s hoof heels. This provides valuable insight into the interaction between equine footwear and hoof function.

Significance and Conclusion

• This research provides a new technique for assessing hoof function in horses and could potentially inform better shoe design or hoof care techniques. This could drastically improve horse health and performance, especially in disciplines where ground surface interactions are key, such as show jumping or racing.
• While the research provides valuable insights into hoof function, the question of how to optimise equine footwear for varying conditions while minimising negative effects remains open for further investigation.
