Effect of a Pessoa training aid on temporal, linear and angular variables of the working trot.

This study investigates how the use of a Pessoa training aid (PTA), a system of ropes and pulleys, affects the trotting motions and posture of horses. The results showed significant changes in the animals’ speed, stride length, and head angle, suggesting that a PTA might be beneficial for posture improvement, core muscle stimulation, and overall performance, without putting extra strain on the legs.

Objective of the Study

• This paper aims to assess the effects of a Pessoa training aid (PTA) on a horse’s trot – specifically, its linear, angular, and temporal aspects. The researchers wanted to gather more information about the effectiveness of PTAs, which are widely used in equine training and rehabilitation, but have limited evidence-based studies supporting their use.

Method

• The study involved twelve horses undertaking trotting tests in two conditions: without (WO) and with a PTA (WP). The circle on which the horses were lunged had a diameter of 16m, and the PTA was set level with the horse’s shoulder
• Data was collected using high-speed motion capture (125 Hz) and inertial measurement units.
• Subjective video assessment was also carried out by the researchers, who used it to supplement and corroborate the objective data gathered.

Results

• The results of the study suggest that applying a PTA results in significant changes in the horse’s speed, stride length, and head and lumbosacral angles.
• There was also a noticeable change in the highest point of the horse between the two conditions. Without the PTA, the poll (top part of the horse’s head) was the highest point, but this changed to the crest (top of the neck) when the PTA was applied.
• The study also found that the displacement of the middle of the horse’s back was higher with PTA use. The overall impression grade was also higher when the horses used a PTA.

Implications and Further Research

• The results imply that PTAs may have benefits for general training and rehabilitation. They seem to improve posture, generate core muscle activation, and enhance the overall manner of movement. Furthermore, they do this without increasing the load on the structures of the forelimb and hindlimb.
• The researchers highlighted the need for more in-depth study to understand the precise mechanisms behind these changes. Understanding these mechanisms might lead to more specific and effective uses of PTAs in equine therapy and training.
