BACKGROUND: Distal limb wraps are widely used during equine exercise, but their effects on post-exercise kinematics and movement symmetry remain poorly defined.
AIMS/OBJECTIVES: To determine whether elastic and fleece distal limb wraps alter temporal stride variables, distal limb kinematics, and axial movement symmetry after standardised round-pen exercise.
METHODS: Six adult horses completed a prospective crossover study with three conditions: no wraps, elastic wraps, and fleece wraps. Wraps were applied bilaterally to all distal limbs at an initial pressure of 20 mmHg. After 20 minutes of free round-pen exercise, kinematic data were collected on a 50 m sandy track using seven inertial measurement units.
RESULTS: During walk, wrap condition affected mean duty factor (P = 0.041), left forelimb stance duration (P = 0.022), and right forelimb retraction (P = 0.015). Fleece wraps increased left forelimb stance duration by 0.043 s (95% CI 0.008-0.079; P = 0.027) and mean duty factor by 1.14 percentage points (P = 0.045) versus no wraps. Elastic wraps increased right forelimb retraction magnitude by 3.27° versus no wraps (95% CI 0.50-6.04; P = 0.031). During trot, elastic wraps increased mean duty factor by 5.71 percentage points versus no wraps (P = 0.040) and reduced left forelimb swing duration by 0.032 s versus fleece wraps (P = 0.018). Axial movement symmetry was unchanged.
CONCLUSION: Distal limb wraps produced gait- and material-dependent post-exercise changes in selected temporal and distal limb kinematic variables, particularly during walk, without consistent changes in axial movement symmetry.
