Electromyography (Overview)

Emg (electromyography) is a test of your muscles and nerves. It is typically performed along with nerve conduction studies (ncs). The EMG portion involves placing a recording pin (like a fine wire antenna) into various muscles, looking for 'muscle distress signals' that could suggest nerve or muscle diseases/problems. Nerve conduction studies involve stimulating nerves & recording their signals.

What is electromyography (emg )?

What is electromyography (emg )?

Electromyography: Emg and ncv testing is used to help diagnose nerve and muscle problems. Examples include spinal nerve impingement (from herniated disc), carpel tunnel syndrome, ulnar syndrome, sources of radiating pain. Pain, numbness, weakness, muscle fatigue are some of the reasons that you may need an emg/ncv test. ...Read more

What exactly is electromyography?

Nerve & muscle test: Electromyography (EMG) is usually performed alongside nerve conduction studies in order to test the function of nerves and muscles. Emg involves placing a pin (like a fine wire antenna) into various muscles, looking for distress signals that can suggest nerve or muscle problems. Nerve conduction studies involve stimulating a nerve and measuring various facets of nerve conduction. ...Read more

What is electromyography used for?

Nerve & muscle test: Electromyography (EMG) is typically performed along with nerve conduction studies. When performed by a skilled physician (who also does a history & physical exam), these tests can identify nerve & muscle conditions at any point in the 'circuit' from part of the spinal cord, nerve root (exiting your spinal column), through the plexus, peripheral nerve, neuromuscular junction, and muscle. ...Read more

I have to take a electromyography (emg) test. How do I prepare?

Relax: First you need to show up. Be prepared to sit relatively still for about an hour. The test works best if you relax during it. It is very well tolerated but there may be aspects that are uncomfortable for a very short time. The EMG portion is done with a needle that measures muscle activity. It should not be very painful. Most folks tolerate it well.The results are very useful for your treatment. ...Read more

Can someone list the disorders that might be diagnosed with electromyography?

EMG: Electromyography or EMG is a test used to look at muscle activity which is reflective of nerve activity. This is often done in conjunction with nerve conduction velocity (ncv) testing. This is done by measuring muscle activity over a stimulated nerve. These 2 tests can help diagnoses nerve disorders, muscle disorders, neuro-muscular junction disorders. ...Read more

Can someone list the disorders that might be possible with abnormal electromyography results?

Too many to list.: Electromyography is performed for abnormal symptoms such as weakness due to conditions in either muscles or peripheral nerves. There are many such conditions. This web page (http://www.Nlm.Nih.Gov/medlineplus/ency/article/003929.Htm) has a list of many of these conditions, but you should always speak with your doctor about your specific results. ...Read more

What is the definition or description of: nerve conduction and electromyography?

What is the definition or description of: nerve conduction and electromyography?

See below: An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerve conduction studies measure how well and how fast the nerves can send electrical signals. An EMG is done to find diseases that damage muscle tissue, nerves. A nerve conduction study is done to find damage to the peripheral nervous system. ...Read more

Can a neurologist lessen pain you during an electromyography?

Can a neurologist lessen pain you during an electromyography?

Probably not: Feeling pain intensity is very subjective, i usually engage patient in conversation so their attention is diverted, sometimes recruitment analysis can give answer with less pain than full interference testing which is usually more painful. ...Read more
