Forelimb biokinematics at the walk differ significantly between Andalusian (AN), Arab (AR), and Anglo-Arab (AA) horses. Key differences were found in limb retraction and joint angular movements during the stance phase.

Area of Science:

  • Equine biomechanics
  • Animal locomotion analysis
  • Comparative zoology

Background:

  • Understanding equine locomotion is crucial for performance and welfare.
  • Previous studies have not comprehensively analyzed forelimb biokinematics across different horse breeds at the walk.

Purpose of the Study:

  • To determine and compare linear, temporal, and angular biokinematic characteristics of the forelimb at the walk in Andalusian, Arab, and Anglo-Arab stallions.
  • To identify significant inter-breed differences in forelimb movement patterns.

Main Methods:

  • Kinematic analysis of forelimb movement in 23 healthy stallions (10 Andalusians, 7 Arabs, 6 Anglo-Arabs) at the walk.
  • Video recording at 25 frames/s, digitization, and analysis using a semi-automatic movement analysis system.

  • Statistical comparison of temporal and angular variables, including stance phase percentages and joint range of motion.

    • Main Results:

    • No significant differences in walking speed were observed between breeds.
    • Significant inter-breed variations were found in deceleration and propulsion percentages during the stance phase.
    • The carpal joint showed the greatest angular range difference (higher in Andalusians), and the fetlock joint exhibited significant minimum value differences across all breeds.
    • Andalusian horses had the lowest maximum limb retraction, impacting angular range of motion.

    Conclusions:

    • Inter-breed differences in equine forelimb biokinematics at the walk are significant.
    • This study successfully distinguished between Andalusian, Arab, and Anglo-Arab horses based on their forelimb movement characteristics.
