Electromyogram (EMG)

The electromyogram (EMG) is a medical examination that allows us to study the functioning of the nerves and muscles, moreover we speak more exactly of electroneuromyogram. This is an essential examination to establish or confirm a diagnosis.

What is EMG?

The doctor places electrodes on the skin or (more rarely) in the muscle. In practice, it is to put on the skin a kind of patch or a small metal ring connected to the device. It is sometimes necessary to push a very thin needle (almost painless) into the skin, to reach muscle fibers.

EMG can record and analyze the conduction of nerve impulses in certain nerves up to a muscle. This analysis focuses on motor nerves, sensory nerves and muscles.

In which recourse to the EMG?

Due to the occurrence of certain symptoms, the doctor may prescribe an electromyogram: if the person perceives tingling that is repeated or persistent, or other abnormalities of sensitivity; if the person experiences certain motor difficulties with a hand, a leg, a foot ... For example, if a person presents the symptoms suggestive of a carpal tunnel syndrome, an EMG will be asked for possibly consider surgery.

Of course, it is after having examined the patient and having thought about different diagnoses that the doctor proposes to perform an electromyogram.

It is the general practitioner or more particularly a neurologist or a rheumatologist who usually ask for an electromyogram.

Screening for colon cancer

Colorectal cancer is a malignant tumor that develops from the lining of the colon (or large intestine), or rectum.
