Why are my horses legs shaking?
The classic disease called Shivers is a gradually progressive, chronic neuromuscular disease in horses that is characterized by gait abnormalities when backing up. Other typical signs include trembling of the tail while held erect, trembling of the thigh muscles and a flexed and trembling hind limb.
Why do horses back legs shake?
Shivers is an nervous abnormality, or dysfunction of the nerve, that manifests largely in the hindlegs, which twitch and ‘shiver’ when lifted. There’s no definitive known cause, no known cure or treatment, and while draught-type breeds tend to be most commonly affected, finer Thoroughbred types can suffer, too.
What causes tremors in horses?
Pathogenesis. The cause of shivers is currently unknown. Horses with shivers have been shown to have degeneration of the axons of their cerebellar Purkinje cells, although Purkinje cell number remains normal. The strong breed predilection suggests a genetic basis to the disease.
How do you prevent muscle tremors in horses?
If a horse has both PSSM and Shivers, owners have reported improvements in their horses by feeding a diet high in fat and low in starch. This does not appear to cure horses from Shivers but it may reduce the frequency of muscle spasms. Adequate levels of vitamin E and Selenium are important in the diet.

What causes muscle twitching in horses?
There are many potential causes for muscle spasms in horses. Dehydration and electrolyte imbalance in the extracellular fluid is the most common cause. Excessive sweating causes dehydration and loss of electrolytes.
Why is my horse muscle spasms?
When abnormal alterations occur in the physiology of muscles, a horse may experience painful, uncontrollable, and continuous muscle contractions. This condition is called tying-up, or rhabdomyolysis, and is comparable to severe cramps that a human might experience.
How do you know if your horse is lame in hind legs?
If the horse is lame on a front leg, the horse will dip its head downward. 1 If the horse pops its hip slightly upward, the lameness is in the hindquarters or back legs. If a horse is obviously lame on both front or rear legs, there may be no head bob. Their strides will likely be choppy and short.
What causes muscle Fasciculations in horses?
Muscle fasciculations can be a physiological response to pain, fear and anxiety. They also arise from viral encephalitis (west nile virus), electrolyte abnormalities (hypocalcemia), parasitic infections (Otobius Megnini ear ticks) and hereditary disorders of muscle (HYPP, myotonia).
