An abnormal EMG result means there is a problem in an area of muscle activity—turning on and off, when it is active, how much it is active, if it is more or less active, and fatigue. This can offer a clue in diagnosing various nerve and muscle conditions. Learn more in 10 Conditions Diagnosed With an EMG.

10 Conditions Diagnosed With an EMG
What is an EMG test used to diagnose?
EMG testing is used to diagnose conditions that cause muscle tissue damage or damage to the junctions between the muscles and nerves. Conditions that can cause these problems include Lou Gehrig’s disease, myasthesnia gravis, and herniated disc. The EMG test can also be used to find the reason for muscle weakness or twitching.
How do I interpret my EMG results?
A doctor who specializes in neurology or neurosurgery will interpret your EEG results in the context of other tests and clinical information. The test can only reveal what is happening in the brain; it can’t explain why it’s happening. That requires the expertise of your doctor.
What to expect during your EMG test?
What to Expect During Your EMG Test. You are being sent to the electromyography (EMG) lab because you have numbness, tingling, pain, weakness, or muscle cramping. Some of the tests that Dr. Ellis may use to diagnose your symptoms are nerve conduction studies (NCSs), and needle EMG. Dr. Ellis will examine you to decide which tests to do.
What diseases can be diagnosed with an EMG?
An EMG can be used to diagnose a wide variety of neuromuscular diseases, motor problems, nerve injuries, or degenerative conditions, such as: Amyotrophic lateral sclerosis (ALS) Carpal tunnel syndrome. Cervical spondylosis. Guillain-Barre syndrome. Lambert-Eaton syndrome. Muscular dystrophy. Myasthenia gravis.
What is an EMG test?
An EMG—electromyogram—is a test that checks the health of nerves and muscles. An EMG involves inserting tiny needles into your muscles to record electrical activity. Your doctor may recommend this nerve conduction study to help diagnose nerve and muscle diseases and seizures.
Is an EMG an electrodiagnostic study?
Electromyography (EMG) is a form of electrodiagnostic testing that is used to study nerve and muscle function. It is commonly performed by a physiatrist or neurologist with special training for this procedure. An EMG nerve test can provide your doctor with specific information about the extent of nerve and/or muscle injury…
What other test is done during an intramuscular EMG?
What other test is done during an intramuscular EMG? A nerve conduction velocity (NCV) test is often done at the same time as an EMG. In this test, the nerve is electrically stimulated while a second electrode detects the electrical impulse ‘down-stream’ from the first.
