Summary
# Editorial Summary: IMU Technology for Equine Gait Assessment in Italian Breeds Inertial measurement units offer objective quantification of movement traits in horses, addressing a pressing need as traditional Italian light horse breeds face market pressures to demonstrate competitive qualities alongside conservation goals. Researchers collected IMU data from two Italian breeds across multiple trials, examining how environmental conditions, individual biometric characteristics, and measurement repeatability influenced kinematic outputs, whilst correlating sensor readings against standardised judge evaluations and exploring their capacity to predict performance rankings. The technology proved repeatably reliable across trials and generated strong correlations with expert assessments of gait quality, though environmental variables and individual morphology did influence some kinematic parameters, suggesting these factors require statistical control in breeding evaluation protocols. For practitioners involved in breed selection and development, IMU-based gait analysis provides a standardised, quantifiable alternative to subjective visual assessment alone—particularly valuable when identifying breeding stock with commercially desirable movement traits, though interpretation should account for individual conformation and testing conditions. This objective approach could help modernise Italian breed programmes by demonstrating gait merit to contemporary sport and leisure markets whilst maintaining genetic integrity.

Practical Takeaways
- •IMU technology offers an objective, repeatable alternative to subjective judge scoring for gait assessment in breed evaluation and selection
- •Environmental conditions and horse biometrics should be standardized or accounted for when using IMU data to ensure consistent gait measurements across different assessment occasions
- •Consider integrating IMU gait analysis into breeding programs for Italian breeds to objectively identify horses with desirable movement traits and support market adaptation
Key Findings
