Stringhalt, a neurological disorder affecting horses, is a topic of significant importance in the equine industry. As a condition that can cause sudden, involuntary flexion of a horse’s hind legs, stringhalt can lead to lameness, decreased performance, and even safety risks for both the horse and its rider. Understanding the causes of stringhalt is crucial for horse owners, breeders, and veterinarians to provide effective prevention, diagnosis, and treatment strategies.
Overview of Stringhalt in Horses
Stringhalt is a complex and multifaceted condition that can manifest in different forms, including Australian stringhalt, classical stringhalt, and idiopathic stringhalt. While the exact causes of stringhalt are still not fully understood, research has identified several factors that contribute to its development. These include genetic predisposition, nutritional deficiencies, environmental toxins, and physical trauma.
Genetic Factors
Some breeds, such as the Peruvian Paso, are more prone to developing stringhalt due to their genetic makeup. Research suggests that a genetic mutation may be responsible for the condition in these breeds.
Environmental and Nutritional Factors
Dietary deficiencies, particularly a lack of certain nutrients like vitamin E and selenium, may contribute to the development of stringhalt. Exposure to certain toxins, such as those found in some plants, has also been linked to the condition.
Physical Trauma and Other Factors
In some cases, physical trauma, such as a fall or injury, may trigger the onset of stringhalt. Other factors, including age, sex, and management practices, may also play a role in the development of the condition.
In this article, we will delve deeper into the causes of stringhalt in horses, exploring the latest research and expert insights to provide a comprehensive understanding of this complex condition.
What Causes Stringhalt in Horses?
Stringhalt is a neurological disorder that affects horses, causing them to exhibit an abnormal gait, characterized by a sudden, involuntary flexion of one or both hind legs. This condition can be frustrating and challenging for horse owners, as it can impact the horse’s performance, comfort, and overall well-being. In this article, we will delve into the possible causes of stringhalt in horses, exploring the various factors that contribute to its development.
Genetic Factors
Research suggests that genetic factors may play a role in the development of stringhalt. Some breeds, such as the Peruvian Paso, are more prone to stringhalt due to their genetic makeup. Additionally, horses with a family history of stringhalt are more likely to develop the condition. (See Also: What Do Gay Horses Eat)
Studies have identified several genetic mutations that may contribute to stringhalt, including:
- Mutations in the glycogen synthase 1 (GYS1) gene, which is involved in glycogen metabolism.
- Mutations in the ryanodine receptor 1 (RYR1) gene, which is involved in muscle contraction and relaxation.
- Mutations in the calcium channel voltage-dependent alpha1 subunit (CACNA1S) gene, which is involved in muscle contraction and relaxation.
Environmental Factors
Environmental factors, such as diet, exercise, and management practices, can also contribute to the development of stringhalt. For example:
- Dietary deficiencies, particularly a lack of essential nutrients such as vitamin E and selenium, may increase the risk of stringhalt.
- Overexertion or excessive exercise, especially in young horses, can lead to muscle strain and injury, which may trigger stringhalt.
- Poor footing, such as slippery or uneven surfaces, can cause horses to alter their gait, leading to stringhalt.
- Management practices, such as rapid changes in diet or exercise, can stress horses and increase the risk of stringhalt.
Infectious and Inflammatory Causes
Infectious and inflammatory conditions can also cause stringhalt in horses. For example:
- Equine protozoal myeloencephalitis (EPM), a parasitic infection, can cause neurological signs, including stringhalt.
- West Nile virus, a viral infection, can cause neurological signs, including stringhalt.
- Equine herpesvirus, a viral infection, can cause neurological signs, including stringhalt.
- Inflammatory conditions, such as arthritis or tendonitis, can cause pain and discomfort, leading to stringhalt.
Other Possible Causes
In addition to genetic, environmental, and infectious/inflammatory causes, other factors may contribute to the development of stringhalt in horses. These include:
- Age, as stringhalt is more common in older horses.
- Sex, as geldings are more prone to stringhalt than mares or stallions.
- Breed, as certain breeds, such as the Peruvian Paso, are more prone to stringhalt.
- Conformation, as horses with certain conformational traits, such as a long back or straight hind legs, may be more prone to stringhalt.
Diagnosis and Treatment
Diagnosing stringhalt can be challenging, as it requires a thorough physical examination, medical history, and diagnostic tests, such as radiographs, ultrasound, and electromyography. Treatment typically involves a combination of:
- Rest and rehabilitation, to allow the horse to recover from any underlying conditions.
- Pain management, to alleviate discomfort and pain.
- Physical therapy, to improve flexibility and range of motion.
- Surgical intervention, in some cases, to address underlying conditions, such as tendonitis or arthritis.
Prevention and Management
Preventing stringhalt in horses involves: (See Also: Are There Female Horses In The Kentucky Derby)
- Proper nutrition, ensuring a balanced diet that meets the horse’s nutritional needs.
- Adequate exercise, providing regular, gentle exercise to maintain muscle tone and flexibility.
- Regular veterinary care, monitoring the horse’s health and addressing any underlying conditions.
- Proper management practices, avoiding rapid changes in diet or exercise, and providing a safe, comfortable living environment.
Conclusion
In conclusion, stringhalt in horses is a complex condition with multiple possible causes, including genetic, environmental, infectious, and inflammatory factors. as well as other contributing factors. Understanding the underlying causes of stringhalt is essential for developing effective prevention and treatment strategies. and improving the welfare of affected horses.
By recognizing the importance of proper nutrition, exercise, veterinary care, and management practices, horse owners can reduce the risk of stringhalt and provide their horses with a better quality of life.

Frequently Asked Questions: What Causes Stringhalt in Horses
What is Stringhalt in horses?
Stringhalt is a condition that affects the gait of horses, characterized by a sudden, involuntary flexion of one or both hind legs. This can cause the horse to lift its leg high and hold it in a flexed position for a short time before placing it back on the ground.
What are the common causes of Stringhalt in horses?
The exact cause of Stringhalt is still unknown, but several factors are believed to contribute to its development. These include genetics, injury or trauma to the nerves or muscles, and certain medical conditions such as equine protozoal myeloencephalitis (EPM) and cervical vertebral compressive myelopathy. (See Also: Does A Carousel Only Have Horses)
Can Stringhalt be caused by nutritional deficiencies?
Yes, nutritional deficiencies, particularly a lack of certain vitamins and minerals, may contribute to the development of Stringhalt in horses. For example, a deficiency in vitamin E or selenium may affect the health of the nerves and muscles, leading to Stringhalt.
Can Stringhalt be prevented?
While Stringhalt cannot be completely prevented, there are steps that horse owners can take to reduce the risk of their horse developing the condition. These include providing a balanced diet, ensuring regular exercise and turnout, and minimizing the risk of injury or trauma to the horse.
Is Stringhalt treatable?
Yes, Stringhalt can be treated, although the effectiveness of treatment varies depending on the underlying cause of the condition. Treatment may involve managing the underlying condition, providing physical therapy and rehabilitation, and using medications to alleviate symptoms.
