Knoxville Hospital & Clinics provides patients with a skilled physician who specializes in disorders affecting the nerves and muscles. Electromyography (EMG) is a diagnostic test that measures how well the muscles and nerves work. Providers use EMG to diagnose injuries, muscle disease, and neuromuscular disorders.
