Electrodiagnostic testing involves two separate tests – electromyography (EMG) and nerve conduction studies. The first is used to evaluate the function of the muscles and electrical activity within them when at rest and in use. Nerve conduction studies are used to evaluate the function of the nerves and how well they transmit electrical signals. The results can tell your doctor if symptoms are caused by damage to muscles, nerves, or potentially some other unrelated problem.
Did you know?Electrodiagnostic testing can diagnose and help determine the severity of a number of conditions. Examples include nerve damage, peripheral neuropathy and myopathy. Electrodiagnostic testing is also a helpful tool for diagnosing focal neuropathies, such as carpal tunnel syndrome.
