Summary
This study created a database of equine back kinematics to objectively assess function. Findings reveal relationships between movement, age, gender, and use in horses, aiding diagnosis.
Area of Science:
- Equine biomechanics
- Veterinary orthopedics
- Animal locomotion analysis
Background:
- Subjectivity in diagnosing equine back dysfunction necessitates objective evaluation methods.
- Current diagnostic approaches rely heavily on clinical history and examination, which can be inconsistent.
Purpose of the Study:
- To develop an objective clinical tool for evaluating equine back function.
- Establish a comprehensive database of back kinematics in healthy riding horses at walk and trot.
Main Methods:
- Collected morphometric and kinematic data from 33 riding horses on a treadmill.
- Analyzed correlations between movement parameters, age, height, weight, stride length, gender, and discipline (dressage/showjumping).
Main Results:
- A database quantifying range and symmetry of motion (extension, flexion, lateral bending, rotation) was generated.
- High symmetry values were observed across all kinematic variables.
- Significant differences in kinematics were noted based on horse usage and gender.
- Age showed a negative correlation with thoracolumbar extension and flexion.
Conclusions:
- Established interrelationships between equine use, gender, and age concerning conformation and movement.
- The developed database serves as an objective reference for diagnosing, treating, and rehabilitating equine back dysfunction.
