Stringhalt in horses is a neuromuscular disorder that causes excessive and involuntary flexion of the hind limbs. Stringhalt affects a horse’s ability to walk, trot, and can even make them stumble or fall.
It is thought to be caused by damage or irritation to the nerves that control the muscles in the hind limbs.
1. What Is Stringhalt In Horses?
Stringhalt in horses is a neuromuscular disorder that affects the movement of the hind limbs. It is characterized by an abnormal and exaggerated flexion of the hind legs, often accompanied by a sudden jerking motion or ‘snapping’ action. This condition can be unilateral, affecting only one leg, or bilateral, affecting both legs.
Stringhalt is a condition that primarily affects horses and is characterized by an abnormal flexion of the hind limbs. It is believed to be caused by a malfunction of the nerves that control the muscles responsible for limb extension. While the exact cause of stringhalt is unknown, it has been associated with various factors such as toxic plants, nerve damage, and certain medical conditions.
Horses with stringhalt often display distinctive symptoms, including exaggerated flexion of the hind legs, a high-stepping gait, and an involuntary ‘snapping’ action when moving. These symptoms may worsen during turns or when the horse is asked to back up. Additional signs may include muscle tremors, stiffness, and difficulty in transitioning between gaits.
While the exact causes of stringhalt remain unclear, several factors have been identified as potential contributors. These include ingestion of toxic plants such as flatweed or false dandelion, nerve damage caused by trauma or surgery, and certain medical conditions such as equine protozoal myeloencephalitis (EPM) or vitamin E deficiency. Furthermore, it has been observed that some cases of stringhalt occur in certain breeds with a genetic predisposition to the condition.
1.1 Types Of Stringhalt
Stringhalt is a condition that affects horses and causes abnormal movements in their hind limbs. There are different types of stringhalt, each with its own distinct characteristics. Understanding these types is essential for proper diagnosis and treatment.
The first type of stringhalt is known as “classical” stringhalt. Horses with classical stringhalt display exaggerated and jerky movement in their hind limbs, especially when walking or trotting. This can make it difficult for them to move smoothly and can lead to tripping and stumbling.
Another type of stringhalt is called “Australian” stringhalt. Horses with Australian stringhalt have a more severe form of the condition, with exaggerated and sudden movements of the hind limbs. These movements may be triggered by stress or excitement and can make it challenging for the horse to perform regular activities.
Differentiating between these types of stringhalt is crucial for determining the appropriate treatment plan. Although there is currently no cure for stringhalt, various management techniques and therapies can help alleviate symptoms and improve the horse’s quality of life. It is always recommended to consult a veterinarian for a proper diagnosis and guidance regarding the best course of action for a horse with stringhalt.

Disorders such as equine dysautonomia can result in damage to the nerves that control the hind legs, leading to the characteristic stringhalt movements. In some cases, spinal cord compression or trauma can also cause neurological stringhalt.
Neuromuscular Causes of Stringhalt: Another potential cause of stringhalt is a problem with the muscles themselves. Conditions such as equine polysaccharide storage myopathy (EPSM) or mitochondrial myopathy can result in muscle dysfunction and spasms, leading to stringhalt-like movements. Disorders affecting the neuromuscular junction, such as botulism or tetanus, can also cause similar symptoms.
Environmental Causes of Stringhalt: Certain environmental factors can trigger or exacerbate stringhalt in horses. Grazing on pastures containing toxic plants, such as flatweed or buckwheat, can result in stringhalt-like symptoms. Additionally, some cases of stringhalt may be associated with nutritional deficiencies or imbalances, although more research is needed to fully understand the relationship.
Genetic Causes of Stringhalt: Some cases of stringhalt have a genetic component. Certain breeds, such as the Australian Stock Horse, are more predisposed to developing the condition. Ongoing research aims to identify specific genetic mutations or markers associated with stringhalt in order to improve diagnosis and management.
1.3 Diagnosing Stringhalt In Horses
htmlWhen it comes to diagnosing stringhalt in horses, a veterinary examination and evaluation are crucial. The veterinarian will perform a thorough examination of the horse, looking for any signs and symptoms that may indicate stringhalt.
