Stringhalt is a medical condition that affects horses, causing them to exhibit a specific kind of gait abnormality. Horses that suffer from stringhalt exhibit an exaggerated and jerky lifting of the hind legs. This disorder can be a one-sided or bilateral problem, and it worsens when the horse is made to move backward or uphill. The disorder is also known as “springhalt” in some circles.
The specific cause of stringhalt is unknown. However, veterinarians believe that the disorder is related to nerve damage, specifically damage to the femoral nerve or the lateral digital nerve. Etiology of the problem is debatable but injury to the nervous system and toxicity of certain plants are the most common factors believed by veterinary experts. The disorder can affect horses of all types irrespective of their breed, age, and sex. Nonetheless, stringhalt is more likely to occur in older horses and can have a significant impact on their quality of life and athletic ability. Regardless of whether your horse is a professional racehorse or a backyard pet, it is important to understand the causes and symptoms of stringhalt, so you can seek appropriate treatment in case there is any problem.
Symptoms of stringhalt in horses
Stringhalt is a problem that affects horses in their hind legs, causing uncontrolled and exaggerated movements. Symptoms of stringhalt include:
- Abnormal gait, especially when walking or trotting
- Lifting, jerking or kicking up the hind legs abnormally high when moving
- In severe cases, horses may fall over backward when the condition is triggered.
These symptoms can vary depending on the severity of the condition. Some horses will show signs of discomfort when the hind leg is stretched, while others may only have mild symptoms that are barely noticeable.
Types of stringhalt
There are two primary types of stringhalt in horses: Australian and American.
- Australian stringhalt: This type of stringhalt is most common in Australia, New Zealand, and some parts of Europe. It is caused by the ingestion of certain types of plants, such as flatweed or false dandelion. Australian stringhalt typically affects both hind legs, causing them to suddenly and exaggeratedly lift up towards the horse’s belly. This movement can become so severe that the horse may have difficulty walking or standing normally.
- American stringhalt: American stringhalt, also known as idiopathic or sporadic stringhalt, is more common in the United States. The exact cause of this type of stringhalt is not fully understood, but it is believed to be related to nerve damage or muscle abnormalities in the hindquarters. American stringhalt usually affects only one hind leg and causes it to suddenly snap up towards the horse’s belly, similar to the movement seen in Australian stringhalt. However, in American stringhalt, the leg may stay elevated for several seconds or even minutes, and the horse may drag the leg slightly as he moves forward.
Diagnosis and treatment of stringhalt
The diagnosis of stringhalt in horses is based on observation of the horse’s gait and a physical exam, as well as a review of his medical history and any potential exposure to toxic plants. In some cases, additional diagnostic tests such as radiographs or nerve conduction studies may be needed to confirm the diagnosis or rule out other underlying conditions.
Treatment of stringhalt depends on the underlying cause. In cases of Australian stringhalt, the horse’s access to toxic plants must be restricted or eliminated, and supportive care such as anti-inflammatory medication or physical therapy may be helpful. With American stringhalt, treatment can range from conservative management such as exercise modification and medication to surgical intervention in severe cases.
| Treatment Option | Description |
|---|---|
| Exercise Modification | Reducing exercise intensity and duration to minimize the horse’s stringhalt symptoms. |
| Medication | Administering muscle relaxants or anti-inflammatories to minimize the horse’s stringhalt symptoms. |
| Surgery | In severe cases, surgical intervention such as a neurectomy or tenectomy may be necessary to eliminate the horse’s stringhalt symptoms. |
It is important to note that recovery from stringhalt can vary widely depending on the underlying cause and severity of the condition. In some cases, horses may make a full recovery with appropriate treatment, while in others, ongoing management and monitoring may be necessary to ensure the horse’s comfort and quality of life.
Diagnosing Stringhalt in Horses
Stringhalt is a condition that affects the horse’s hind limbs, causing uncontrolled and exaggerated upward movement. It is characterized by sudden and jerky flexion of one or both hind legs, causing the horse to lift its leg high up before putting it back down on the ground. The exact cause of stringhalt is unknown, but it is believed to be related to damage or inflammation of the nerves that control the movement of the hind legs.
- Physical Examination: The first step in diagnosing stringhalt is a thorough physical examination of the horse. The veterinarian will examine the horse’s gait, watch how it moves, and manipulate the hind limbs to look for signs of pain, inflammation, or nerve damage.
- X-Rays: X-rays may be taken to rule out the possibility of the condition being caused by bone or joint abnormalities. X-rays may not be necessary in every case of stringhalt, but they can help in detecting anatomical abnormalities that may contribute to the horse’s symptoms.
- Nerve Blocks: Nerve blocks may be done to locate the exact location of nerve damage or inflammation. During a nerve block, a local anesthetic is injected into specific nerves to temporarily block their function. If the horse shows a sudden improvement in mobility after the nerve block, it indicates that the nerve that was blocked is involved in the stringhalt condition.
Diagnosing stringhalt can be challenging, and it is important to seek professional veterinary care to ensure an accurate diagnosis. In some cases, symptoms may be caused by other conditions such as arthritis, muscle or tendon damage, or neurological disorders, and these must be ruled out before treating the horse for stringhalt.
Treatment options for stringhalt vary depending on the severity of the condition and the underlying cause. Treatment may range from anti-inflammatory medications, corrective trimming and shoeing, or even surgery in severe cases. Your veterinarian will be able to recommend the best course of treatment for your horse based on the specific diagnosis.
| Signs of Stringhalt in Horses | Possible Causes |
|---|---|
| Uncontrolled and exaggerated upward movement of hind legs | Nerve damage or inflammation |
| Sudden and jerky flexion of one or both hind legs | Bone or joint abnormalities |
| Difficulty walking or standing | Muscle or tendon damage |
| Wasting or shrinking of muscle tissue in hind legs | Neurological disorders |
Regular veterinary check-ups and prompt diagnosis and treatment of any symptoms can help prevent the progression of stringhalt and improve the overall well-being of your horse.
Link between stringhalt and selenium deficiency
Stringhalt is a gait abnormality that affects horses and causes them to lift their hind legs unusually high. Although the exact cause of stringhalt is still unknown, there are several theories, including the link between stringhalt and selenium deficiency.
- Selenium is an essential mineral that is involved in many physiological processes in horses, including muscle function, immune system response, and antioxidant protection.
- Low levels of selenium in the diet can lead to muscular problems, including muscle weakness, stiffness, and cramping, which may contribute to the development of stringhalt.
- Research has suggested that horses with stringhalt may have lower levels of selenium in their bodies than healthy horses, although more studies are needed to confirm this association.
Supplementing horses with selenium can help prevent and treat muscle-related problems, including stringhalt. However, it’s important to be cautious when supplementing horses with selenium, as over-supplementing can lead to toxicity.
To avoid selenium toxicity, horse owners should consult with their veterinarian to determine their horse’s selenium status and determine whether additional supplementation is necessary.
| Selenium Level | Possible Effects on Horses |
|---|---|
| Low | Muscle weakness, stiffness, cramping |
| Normal | Healthy muscle function, immune system response, and antioxidant protection |
| High | Anorexia, weight loss, hoof sloughing, blindness, and even death |
Stringhalt can have a significant impact on a horse’s gait and performance. Understanding the link between stringhalt and selenium deficiency can help horse owners take preventative measures and manage affected horses more effectively.
Possible Genetic Factors for Stringhalt
Horses with stringhalt may show a variety of clinical signs, but the exact etiology of the disease remains largely unknown. However, recent research has suggested that there may be genetic factors involved in the development of stringhalt in horses.
- Researchers have identified several breeds, including the Australian Stock Horse, Standardbred, Warmbloods, and Thoroughbreds, that appear to be more susceptible to stringhalt than other breeds.
- Studies have also suggested that there may be a genetic component to the disease, as some horses seem to inherit the disorder.
- Additionally, there may be a link between the age of onset and certain genetic markers, as horses that develop stringhalt at a younger age may have different genetic factors at play than those that develop the condition later in life.
While more research is needed to fully understand the genetic factors involved in stringhalt, these findings suggest that there may be a hereditary component to the disease that breeders should consider in their breeding programs.
It is also important to note that genetics are not the only factor at play in the development of stringhalt. Environmental factors, such as exposure to toxic plants or viruses, may also play a role. Therefore, a comprehensive approach that addresses both genetic and environmental factors is necessary for preventing and treating stringhalt in horses.
To better understand possible genetic factors associated with stringhalt, an ongoing study at the University of California, Davis is exploring genetic markers associated with the disease. The study aims to identify possible heritable factors that may be used to develop treatments or a cure for stringhalt.
| Genetic markers | Associated with |
|---|---|
| AHDC1 | Late onset stringhalt |
| LGR4 | Early onset stringhalt |
| GJD2 | Generalized stringhalt |
By further understanding the genetic factors involved in stringhalt, we can develop better strategies for preventing and treating this debilitating disease in horses.
Treatment options for stringhalt in horses
Stringhalt in horses is a neuromuscular disorder that affects the hind legs, causing the horse to lift, jerk, or hyperextend its hind legs while walking, trotting, or turning. Although there is no cure for stringhalt, there are several treatment options available that can help manage the symptoms and improve the horse’s quality of life.
- Veterinary Care: If you suspect that your horse has stringhalt, it is critical to consult with a veterinarian. The vet will examine your horse and might take x-rays to rule out any underlying conditions that may cause the symptoms. Once diagnosed with stringhalt, the vet can recommend the best treatment options.
- Medications: There is no specific medication for stringhalt, but some medications can help manage the symptoms. For instance, tranquilizers like acepromazine or sedatives like Diazepam can reduce the severity of stringhalt spasms. However, these drugs can have side effects and should only be used with a vet’s recommendation.
- Botulinum Toxin Injections: Botulinum toxin, also known as Botox, can temporarily paralyze the muscles responsible for stringhalt spasms. The toxin is injected into the horse’s hind leg muscles, and the effect can last up to six months. This treatment option is pricey and may require multiple doses to maintain the effect.
Although the above treatment options can help manage the symptoms of stringhalt, there are several management techniques that horse owners can use to improve the horse’s quality of life.
Diet: Feeding your horse a balanced diet with ample amounts of high-quality forage can help improve overall health and reduce stringhalt symptoms. Horses with stringhalt may need a low-stress environment and regular exercise.
Farrier Care: Proper farrier care is an essential aspect of managing stringhalt. Regular hoof trims and shoeing can help with the horse’s balance and stability, reducing the risk of injury or tripping.
| Treatment Option | Pros | Cons |
|---|---|---|
| Medications | -Helps manage symptoms. -Available. |
-Can have side effects. -Not effective for all horses. |
| Botulinum toxin injections | -Paralyze the affected muscles. -Temporarily effective. |
-Expensive. -Can have side effects. -May require multiple doses. |
Supplementation and Herbs: Certain herbs and natural supplements, such as magnesium, calcium, and Vitamin E, can help reduce muscle spasms and promote nerve function. However, it’s essential to consult with a veterinarian before starting any supplement program to ensure there are no interactions or contraindications with any medication the horse is taking.
Overall, the success of treatment for stringhalt depends on the severity of the symptoms and how the horse responds to the treatment. However, with proper management, owners can provide their horses with an optimal quality of life despite the diagnosis.
Preventing Stringhalt in Horses
Stringhalt is a neurological disorder that affects horses. It causes them to lift one or both hind legs in a rapid, exaggerated manner, which can interfere with their movement and make it difficult for them to walk normally. While the exact cause of stringhalt is unknown, there are several ways to prevent it from occurring in horses.
- Proper Nutrition: A well-balanced diet can help prevent stringhalt. Horses require a diet that provides all the necessary vitamins and minerals. Make sure your horse has access to clean water and quality hay or grass.
- Regular Exercise: Regular exercise is essential to keep your horse in good physical condition, prevent weight gain, and regulate their metabolism. Horses that are inactive for long periods are more susceptible to stringhalt.
- Proper hoof care: Horses require regular hoof trimming to keep their hooves in good condition. Overgrown hooves can cause pain and discomfort, which can lead to stringhalt.
In addition to these preventative measures, there are some other things you can do to reduce the risk of stringhalt in horses.
One of the most important things is to keep your horse away from toxic plants. Some plants, like the flatweed and the Paterson’s curse, can cause stringhalt symptoms in horses. Farmers and horse owners should take steps to remove these plants from pastures and paddocks.
Additionally, horse owners should take precautions with their horse’s environment. A safe environment can reduce the risk of injury and decrease the stress levels of the horse. This reduces the likelihood of neurologic problems and some cases of stringhalt. As part of that safe and non-stressful environment, many horse owners use calming supplements to help reduce stress and anxiety in their horses. A lot of these supplements contain ingredients like l-tryptophan, magnesium, and thiamine that have been shown to have calming effects in horses.
