Electromyogram - Physicians of Katy - Houston


An electromyogram (EMG) is a diagnostic study that has been used by healthcare providers for over 50 years. An EMG provides information about the integrity of the muscle and the nerves in your body. An EMG examination is ordered to evaluate for muscle or nerve damage. Using a computer, monitor amplifier, loudspeaker, stimulator and high tech filters the examiner actually sees and hears how your muscle and nerves are working. As part of the EMG a very small needle is inserted into various muscles in the arm, leg, neck or back where you are having symptoms. 

A clean needle is used on each examination and the needle is thrown up 

Nerve conduction study (NCS)

A nerve conduction study (NCS) is one part of a comprehensive nerve and muscle diagnostic test. Like an EMG a NCS is typically ordered to evaluate for muscle or nerve damage. Once again, the examiner uses a computer, monitor, amplifier, loudspeaker, stimulator and high tech filters to monitor the functioning nerves and muscles your body.

Small electrodes are placed on your skin over muscles being tested in your arms or legs. Then a stimulator is used to deliver a very small electrical current to your skin near nerves being tested, causing your nerves to fire. The electrical signal produced by nerves and muscles are picked up by the computer, and the information is interpreted by our physician trained in electrodiagnostic medicine. The stimulator only produces a very small shock that does not cause damage to your body.

Let us know about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean
