Summary

# Editorial Summary: Ridden Horse Pain Ethogram at Elite Three-Day Events Dyson and Ellis applied a 24-behaviour pain ethogram during dressage warm-up at two 5-star three-day events to establish whether observable pain-related behaviours could predict performance failure and correlate with competition outcomes in 137 horses. Pain ethogram scores ranged from 0–9, with median scores of 3 in clinically non-lame horses rising to 5 in those displaying trot or canter gait abnormalities; critically, 59% of horses scoring ≥7 behaviours failed to complete the cross-country phase, compared with 33% scoring below 7. Moderate correlations emerged between pain ethogram scores and both dressage penalties (rho = 0.4) and final placings (rho = 0.3), whilst horses unable to complete cross-country demonstrated significantly higher pain scores than those that finished. The strong consistency between scores when horses competed at both events (rho = 0.6) validates the ethogram's reliability as a practical diagnostic tool. For equine professionals, these findings underscore that systematic observation of pain behaviours during warm-up provides actionable early warning of compromised welfare and impending performance failure, offering opportunity for intervention before costly competition withdrawal or escalated musculoskeletal injury.

Practical Takeaways

  • Use the 24-behavior RHpE during warm-up to identify horses at risk of cross-country failure; a score ≥7 suggests 59% failure rate and warrants further veterinary investigation before competition
  • Higher RHpE scores correlate with worse dressage performance and final placings, so systematic assessment can inform both welfare decisions and competitive expectations
  • The RHpE is a repeatable, practical tool for detecting subtle musculoskeletal pain early, enabling earlier diagnosis and treatment to improve both welfare and performance outcomes

Key Findings

  • 59% of horses with RHpE score ≥7 failed to complete cross-country phase versus 33% with score <7
  • Moderate correlation (rho=0.4, P<0.001) between RHpE score and dressage penalties
  • Horses with lameness or canter gait abnormalities had significantly higher RHpE scores (P<0.01)
  • Strong correlation (rho=0.6, P<0.001) in RHpE scores for horses competing at both events, indicating tool reliability
