Abstract
Myopathies can present with negative (such as weakness) or positive (such as myalgia and cramps) symptoms. Recognition of certain characteristic patterns of muscle weakness on exam can narrow the differential diagnosis. Serum creatine kinase, focused serologic testing, electromyography, exercise test, muscle imaging, biopsy, and genetic testing are useful to reach a specific diagnosis. The key clinical features, laboratory, EMG, and histopathologic abnormalities of the most common myopathies are discussed below.
