The electromyogram (EMG) is a diagnostic test used by neurologists and other medical specialties to check the function of a person’s nerves and muscles. It differs from the results of CT or MRI which detect a lesion with great clarity but cannot give any information about the functional problems caused by this damage.
EMG is used to diagnose conditions such as:
EMG is a relatively harmless examination, which does not require special preparation, lasting 45-60 minutes.
It consists of two parts:
During the first phase, electrical stimulation of specific groups of nerves is performed and the conduction velocities and other parameters are measured, while in the second phase, a thin needle is inserted inside the muscle, acting as a recorder of the electrical activity of the muscles at rest and during movement.
