Symmetry indices based on accelerometric data in trotting horses.

The research aims at enhancing lameness detection in horses through the use of three symmetry indices derived from accelerometric data. The study was successful in quantifying the high degree of symmetry in trotting horses and demonstrated high repeatability for all three symmetry indices, providing a solid basis for future analysis of these indices for lameness quantification and detection.

Objective and Need for the Research

• The research was necessitated by the need for better methods to detect and quantify lameness in horses. Existing manners are predominantly based on subjective assessment, which leads to discrepancies, especially in the case of low-grade lameness.
• The study aimed to derive more reliable, objective methods by using accelerometric data to construct three symmetry indices. These indices could potentially provide a numerical representation of horse gait symmetry, allowing for more precise identification of any deviations that may indicate lameness.

Methodology and Findings

• The three indices the study created served to measure the overall symmetry of the horse’s gait, the evenness of load placed on each of the horse’s limbs, and the timing symmetry between right and left steps.
• The study found a high degree of gait symmetry in sound (healthy) horses when these indices were applied, replicating results of previous studies using other gait analysis methods. This supports the effectiveness and reliability of the new symmetry indices.

Implications and Future Research Directions

• The high repeatability measured for the three indices underlines their potential to serve as an effective tool for objective identification and quantification of lameness in horses.
• These results lay a solid foundation for further investigations on the symmetry indices, specifically their possible applications in clinical veterinary practice. The integration of these objective numerical methods into lameness detection could significantly improve the accuracy and reliability of such assessments.
