Rarely, horses will show a spastic gait in the front limbs in which the leg is held in full extension or with the knee flexed, with trembling occurring in the upper limb. [2] Despite histologic changes in the cerebellum, horses with shivers do not show clinical signs typical of cerebellar disease (ataxia, intention tremors). [3]

In horses, the disease often progresses gradually and includes clinical signs such as ataxia. In some horses mild clinical signs may herald a rapidly progressive disease course.
