EMG
Electromyography (EMG) is a method for testing the electrical activity of the muscles. This technique is performed using a procedure called electromyography. EMG may help with the diagnosis of nerve root injury or nerve compression injury.

What is the difference in Umbra and Penumbra in Xrays?
Asked by Cudlybuterfly
Penumbra is the excess fog from scatter radiation
What does CMAP mean on EMG tests?
Asked by Wiki User
compound motor action potential
This is an electrical potential evoked by electrically stimulating a motor nerve and recording the electrical response (change in voltage) from a muscle innervated by that nerve.

What are the two major types of EMG's?
Asked by Wiki User
Surface EMG & Needle EMG. Generally speaking, only needle EMG can be used for diagnostic purposes.
Clinical correlation advised after emg and ncs?
Asked by Wiki User
The NCV/EMG is an electrophysiologic exam that can give results or patterns that are sometimes nonspecific or seen in a multitude of clinical conditions. Therefore the referring physicians whom has treated the patient over a period of time and has hopefully examined the patient many times and may know best which condition the NCV/EMG pattern discussed in the report best corresponds with, in his/her patient.
What does no response mean in an EMG test?
Asked by Wiki User
"No Response," or NR, generally occurs during the nerve conduction portion of an electrodiagnsotic examination (often called an EMG). When performing a nerve conduction study an electrical impulse is transmitted through a nerve and recorded at a point distant to that point of stimulation. Normally when this impulse is recorded as a waveform that is produced on the screen for the electromyographer to evaluate. An NR occurs when a waveform cannot be elicited with an electrical impulse. This finding suggests that the nerve being tested has suffered loss of function of some or all of its axons. This does not mean that the nerve being studied is completely dead, but it does suggest significant loss of function in that particular nerve. This "NR" finding may also may be the result of a technical error on the part of the electromyographer.
What is a twitch in electromyography?
Asked by Wiki User
electromyography is about muscle relaxers and contractions testing devise.
What can you have done instead of an MRI scan as you are scared to be put into small spaces?
Asked by Wiki User
There are some MRI machines that are open. Look around in your area to see if there is one available. In some cases, your doctor can prescribe medication to make you more relaxed during the test.
Do you have to both a NCV and an EMG?
Asked by Wiki User
If you have been referred to have an electrodiagnostic examination, that examination will normally involve both a nerve conduction study (NCS) & a needle EMG (nEMG). NCV is sometimes inappropriately used instead of NCS. Both parts of the examination (NCS & nEMG) are equally important in looking at different aspects of nerve and muscle function, and both should be performed. However, in some cases the clinician may determine that NCS or nEMG is contraindicated for some medical reason and may elect not to perform that part of the electrodiagnostic examination.
