Polymyositis - Definition

February 2017


Definition


Polymyositis is a very rare condition characterized by degenerating fibers of the motor muscles, in other words those that enable movements. It sometimes also affects the skin and heart muscles. The exact cause underlying this condition is unknown. The two different types are classified as acute polymyositis, which is temporary; and chronic polymyositis, which is permanent. The symptoms widely vary depending on the type of polymyositis, but fever, painful difficulties in moving the arms and legs, and great fatigue are all usually noted. The treatment is corticosteroid-based, which cannot cure the condition and is accompanied by physiotherapy to slow the condition's progression.
