Your doctor may review the results with you right after the procedure. However, if another healthcare provider ordered the EMG, then you may not know the results until you attend a follow-up appointment with your doctor. If your EMG shows any electrical activity in a resting muscle, then you may have: a muscle disorder.
What are normal nerve conduction test results?
A nerve conduction velocity between 50 and 60 meters per second is generally considered in the normal range. However, any result has to be examined along with other information. Your doctor will compare the results of your test against a standard, or norm, of conduction velocities.
How does nerve damage feel?
Nerve damage may cause loss of sensation or numbness in the fingertips, making it harder to do things with your hands. Knitting, typing, and tying your shoes may become difficult. Many people with nerve damage say that their sense of touch feels dulled, as if they are always wearing gloves.

The sound of positive sharp waves have been described as, like ‘claps of distant thunder’, and fibrillation potentials a higher pitched and shorter duration sound, like ‘rain on a tin roof’.
Does nerve damage show up on MRI?
MRI is sensitive to changes in cartilage and bone structure resulting from injury, disease, or aging. It can detect herniated discs, pinched nerves, spinal tumors, spinal cord compression, and fractures.
How long does a nerve conduction test take?
Nerve conduction studies are usually done before an EMG if both tests are being done. Nerve conduction testing takes 15 minutes to an hour or more, depending upon how many areas are studied.
Why was my EMG so painful?
The Pain of an EMG. Pain is the most common complication of EMG2 causing some level of discomfort in all patients either from the nerve conduction portion or the needle examination. Most surveys find pain more common in the needle portion.
What happens if EMG is abnormal?
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.
Why would someone need an EMG?
EMG results are often necessary to help diagnose or rule out a number of conditions such as: Muscle disorders, such as muscular dystrophy or polymyositis. Diseases affecting the connection between the nerve and the muscle, such as myasthenia gravis.
What diseases does a nerve conduction test show?
Diseases or conditions that may be checked with NCV include:Guillain-Barré syndrome. … Carpal tunnel syndrome. … Charcot-Marie-Tooth disease. … Herniated disk disease. … Chronic inflammatory polyneuropathy and neuropathy. … Sciatic nerve problems.
Can an EMG test make things worse?
Muscle pain from an EMG test gets worse or you have swelling, tenderness, or pus at any of the needle sites.
What diseases can an EMG detect?
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.More items…
Does caffeine affect EMG test?
Preparing the patient for EMG Instruct your patient to avoid caffeine and tobacco products for 3 hours before the test, as these substances can affect test results. Also advise her to wear loose-fitting clothes the day of the test.
