It is a technique that examines muscles and nerves. It consists of 2 steps.
The first stage is transmission study in which how fast the nerves transmit is calculated. A very mild electrical impulse is given to the nerve by an electrode placed on the muscles.
In the second stage, very fine needles are inserted into the corresponding muscles to check activity of these muscles. In this stage, there is no electrical impulse. It is administered to patients with pre-diagnosis such as back and neck hernia, muscle diseases, motor neuron disease, neuropathies, and nerve compressions.
