A Review of Methods for Detecting Soreness in Horses

The research article discusses the methods for detecting discomfort or “soreness” in Tennessee walking horses, typically caused by a practice known as soring to exaggerate their gait for show competitions. The study aims to enhance the reliability of these methods and contribute to the enforcement of the Horse Protection Act (HPA).

Background and Purpose

• The research article revolves around the Tennessee walking horse, a breed widely used for pleasure and show competitions. These horses have a unique four-beat gait called the “running walk”, which has been exaggerated to a “big lick” for high-level competitions.
• To achieve this exaggerated step, a painful practice known as soring is often used, involving the application of substances or devices to a horse’s lower limb to cause discomfort and prompt an exaggerated gait. Despite the Horse Protection Act (HPA) of 1970 prohibiting soring, the practice prevails.
• The paper intends to review the methods used to detect soreness in horses, advocating for an end to soring and improving the welfare of Tennessee walking horses.

Methods of Detection and Advancements

• The study does a comprehensive review of available methods for identifying soreness in horses and assesses their quality and consistency.
• It also uncovers potential, emerging methods, approaches, and technologies adept at detecting pain in a horse’s hoof and pastern, along with its causes.
• This scrutiny is crucial for the identification of research and technological requirements that can improve the reliability of methods to detect soreness in horses.

Significance of the Study

• The study is an independent examination, expected to contribute significantly to shaping HPA inspection protocols. This contribution is vital because it would help enforce the HPA more effectively and scientifically to prevent soring.
• By ensuring these protocols are rooted in solid scientific principles, their application can be more consistent and objective, thereby increasing their effectiveness.
• The research also sheds light on newer methods and approaches for detecting soreness, potentially initiating further research in the area and encouraging technological advancements to better identify and prevent instances of soring.
