Influence of equine conformation on rider oscillation and evaluation of horses for therapeutic riding.

The study investigates how a horse’s size and shape influences rider movement and how this can inform the selection of horses for therapeutic riding. The research found that shorter horses create more rider movement, and wider horses are preferable for riders who need help balancing or with muscular tension release.

Study Design and Implementation

• The research used a sample of 35 horses, which were evaluated based on 24 different conformation indices. Conformation in this context refers to the physical shape and proportions of the horse.
• An accelerometer, a device that measures motion and speed, was attached to the waist of the rider to record rider oscillation, which is basically the movement patterns of the rider while mounted on the horse.
• The spatial position of the rider’s motion was estimated through a method known as double integration of the accelerator values.
• Assessments were carried out by a professional instructor from the Riding for the Disabled Association. Each horse was evaluated based on a scale of 1 to 5 across 27 different evaluation items.

Classification of Horses and Observation of Effects

• Horses were categorized into 4 groups: short and narrow (SN), short and wide (SW), tall and narrow (TN), and tall and wide (TW).
• The research found that rider oscillation rates, or how much the rider moved, were higher on shorter horses compared to taller horses, regardless of whether the horse was at a walk or a trot.
• The vertical and longitudinal amplitudes, which refer to the extent of the rider’s upward-downward and forward-backward movements respectively, were smaller when the horse was trotting if the horse was short compared to a tall horse.
• Horses that were wide resulted in smaller vertical movement of the rider at a walk and larger sideways movement at a trot compared to narrow horses.

Conclusions and Recommendations

• The study concludes that short horses are suitable for riders who require the assistance of side walkers, likely because the greater oscillation can be counterbalanced by the side walkers.
• Wide horses are recommended for riders who have trouble maintaining balance and those looking to relieve muscular tension. The increased lateral motion likely helps with balance by engaging core muscles, and might contribute to muscular relaxation through the rhythmic motion.
• Overall, for therapeutic riding, the research suggests that the most suitable horses would be those that are both short and wide. These horses provide a balance of rider oscillation that is manageable with assistance and beneficial for muscular tension relief and balance training.
