What is inclusion body myositis?

A muscle disease: It is one of many types of muscle disease, typically affecting the organelles that produce energy in the muscle - the mitochondria.

Myopathy type: Ibm is atype of inflammatory myositis. It tends to affect people older than 50. People with ibm often have weakness of their upper and lower arms and legs. Sometimes the muscles look smaller known as atrophy. Unfortunately there are no treatments that are proven to help. However, patients are sometimes tried on a short course of steroids, ivig, etc. Phys therapy is extremely important.

A wide spectrum Pts.: This is an inflammatory muscle disease, with slowly progressive weakness and wasting of both distal and proximal muscles, most notably of the arms and legs. Because this randomly affects different people in different ways and at different rates, there is no "textbook case." there are two kinds, sporadic and hereditary. The hereditary case does not have inflammation and is thus not myositis.
