Weakness comes on slowly (over months to years) in an asymmetric manner and progresses steadily, leading to severe weakness and wasting of arm and leg muscles. IBM is more common in men than women. [10] Patients may become unable to perform activities of daily living and most require assistive devices within 5 to 10 years of symptom onset.
Muscle-atrophy can be induced in pre-clinical models (e.g. mice) to study the effects of therapeutic interventions against muscle-atrophy. Restriction of the diet, i.e. caloric restriction, leads to a significant loss of muscle mass within two weeks, and loss of muscle-mass can be rescued by a nutritional intervention. [35]
The usual criteria for a diagnosis of PM are weakness in muscles of the head, neck, trunk, upper arms or upper legs; raised blood serum concentrations of some muscle enzymes such as creatine kinase; unhealthy muscle changes on electromyography; and biopsy findings of (i) muscle cell degeneration and regeneration and (ii) chronic inflammatory ...

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. Proximal muscle weakness can be seen in Cushing's syndrome [18] and ...
One study showed that eating more protein (about 1.2 grams of protein per kilogram of body weight) can help maintain muscle mass and prevent muscle loss in older adults.
