Effect of weight loading on the coronary band interstitial fluid pressure in horses.

This research examines the relationship between weight load and the pressure of interstitial fluid in the coronary band of horse’s limbs, concluding no significant change in interstitial fluid pressure up to a load of 180 kg.

Research Context

• This study measures interstitial fluid pressures, which potentially function in relation to limb load, at two sites within the digital coronary dermis of the cranial digits in standing horses.
• This context seeks to examine if there’s a correlation between weight bearing and the pressures of fluids within body tissues in horses, which could affect their mobility or health.

Research Methodology

• To measure fluid pressure changes and digital load (weight-bearing) measurements simultaneously, modified wick-in-needle and force plate transducers, connected to a microcomputer, were used.
• The measurements were taken from 10 horses and the limbs were loaded with weights between 50 and 180 kg.

Research Findings

• Mean pressure levels were recorded at limb loads between 50 and 80 kg, and between 150 and 180 kg, at the toe and heel of the horse.
• It was found that the average pressures at the toe and at the heel were not significantly different.

Conclusion

• From their observations and measurements, the researchers concluded that in the static limb, no statistically significant change in interstitial fluid pressure occurs at loads up to 180 kg.
• This suggests that the horse’s limbs maintain a stable interstitial fluid pressure even under significant weight load, indicating a potential resilience or built-in protection mechanism against potential health or mobility issues.
