What Causes Horse Muscle Weakness?

Common causes include infections, parasitic diseases, and immune-mediated conditions. Muscle disorders can appear with a variety of signs ranging from muscle stiffness and pain to muscle atrophy, weakness, exercise intolerance, and muscle fasciculations (twitching).

What causes rapid muscle loss in horses?

Immune-mediated myositis (IMM) is an autoimmune disease that causes rapid onset of muscle atrophy (wasting) along the topline and hindquarters. This can result in the loss of 40% of muscle mass within 48 hours that can persist for months. The disease has been identified in Quarter Horses and related breeds.

How do you strengthen a horse’s weak side?

Riding over raised poles (cavaletti) is helpful for developing strength in the horse that has weak stifles or hocks. The slow action of lifting the hind legs up and over the pole will strengthen the Tensor muscle as well as the Long Digital Extensor. Both muscle groups are responsible for the stability of the stifle.

How do horses act with EPM?

EPM is a neurologic disease that horses get from eating infected opossum feces. Incoordination, muscle atrophy and loss of feeling around the body are a few signs of illness. Keep your horses healthy by storing grain in sealed bins and controlling opossum populations around your barn.
