Determination of the center of pressure of the hoofs of the forelimbs of horses standing on a flat level surface.

The research investigates the pressure distribution on the hoofs of the front limbs of adult horses when they stand on a flat level surface. The findings reveal a significant portion of that pressure is centered in the medial heel area.

Research Methodology

• The sample group involved 23 healthy adult horses with recently trimmed, unshod hooves
• The horses were tranquilized and the pressure they exerted on a flat surface was measured through a pressure-sensitive film placed on a bespoke cassette
• The hooves were closely observed for any movement during the measurement process
• The film was then carefully checked for any signs of improper alignment or slipping of the hoof

Measurement and Analysis

• The center of pressure was identified using the method of weighted proportions, as recommended by Barrey
• A static measurement system was employed, supplemented by a high number of measurements, to limit the influence of variables inherent in the horses’ behaviour and the measuring system itself
• The identified pressure point was recorded as either being medial to, lateral to, or on a line dissecting the central sulcus of the frog (the groove located in the middle of the hoof)
• In the dorsal to palmar orientation, the pressure point was categorized with regard to a line drawn halfway between the most dorsal and the most palmar mark on the film
• Analysis revealed that approximately 46% of calculated center points of pressure were located in the medial heel area, which is significant when compared to a random distribution
• In an expanded perspective, 76% of the centers were identified in or on the borders of the medial heel

Conclusions

• The research provides significant insights into understanding the mechanics of hooved locomotion
• The findings demonstrate a concentrated pressure focus in the medial heel area when horses are standing
• The results may contribute to the development of more effective methods for horseshoe fitting, hoof care, and the prevention and treatment of hoof related disorders
