Equine poor performance: the logical, progressive, diagnostic approach to determining the role of the temporomandibular joint.
Abstract: Poor performance is an ambiguous term used frequently by people in the horse industry. It means different things to different people, depending on the breed, discipline, or problem being discussed. There are myriad reasons that a horse may fail to achieve the expectations put upon it or, having achieved those goals, begin to falter. Equine temporomandibular joint (TMJ) disease is beginning to be reported as 1 such cause of poor performance. Despite this, in certain disciplines, it has become the trendy diagnosis, and a logical approach to the diagnostic workup is often lacking. Many of the clinical signs attributed to TMJ abnormalities can be readily explained by other more common problems. This ambiguity is compounded by a lack of extensive scientific evidence linking TMJ-related disease to behavioral or performance changes. Despite this fact, the equine TMJ has been reported to be a cause of poor performance, and while rare, it should be included in a differential diagnosis list, albeit one of exclusion. The purpose of this article is to describe a logical, stepwise approach to excluding common causes of poor performance before investigating the potential role of the TMJ in cases of poor performance.

The research article investigates the potential role of Temporomandibular Joint (TMJ) disease in horses’ poor performance and proposes a step-by-step approach to diagnosing this before attributing poor performance to more common causes.
Understanding the Context
- Poor performance in horses is a subjective term often used within equestrian circles, its meaning largely depends on the context – the breed of the horse, the discipline, or the specific problem in question.
- The Temporomandibular Joint (TMJ) disease has started to be identified as a potential cause for poor performance in horses. However, this is often branded as a trendy diagnosis without a logical or consistent diagnostic approach.
Challenges in Diagnosing TMJ
- Many of the clinical signs that are associated with TMJ disease can easily be attributed to other, more common issues. This makes it difficult to accurately diagnose TMJ as the root cause of poor performance.
- There is a lack of scientific research that conclusively links TMJ-related diseases with changes in a horse’s behavior or performance.
TMJ as a Potential Cause of Poor Performance
- Despite the aforementioned challenges, TMJ has been reported as a cause of poor performance in horses. While these cases are rare, they are noteworthy enough to warrant consideration in a differential diagnosis.
- A differential diagnosis is a systematic method used by doctors to identify a disease or condition in a patient. Based on the presence of signs and symptoms, a list of potential causes is established and narrowed down until the correct diagnosis is reached.
Proposed Diagnostic Approach
- The main aim of this research is to describe a logical, stepwise approach to exclude common causes of poor performance before considering the role of the TMJ.
- This approach ensures that common conditions are not overlooked in favor of trendier, but rarer, diagnoses such as TMJ diseases.
