Muscle weakness, or myasthenia, is a decrease in strength in one or more muscles. It is a common symptom of muscular, neurological and metabolic disorders. Muscular diseases, such as muscular dystrophy and dermatomyositis (disorder characterized by muscle inflammation), are common causes of muscle weakness.
Muscle weakness can also be classified as either  proximal  or  distal  based on the location of the muscles that it affects. Proximal muscle weakness affects muscles closest to the body's midline, while distal muscle weakness affects muscles further out on the limbs.
