EMG stands for Electromyography, which is the recording of electrical activity of nerves and muscles.

The recording allows the doctor to evaluate and assess the functioning of these nerves and muscles.

The initial study consists of two parts:

1The first part of the test involves Nerve Conduction Studies which in most cases is performed by a technologist. The purpose of this part of the test is to measure the ability of nerves to transmit electrical impulses and also communicate with the respective muscles. This section of the EMG testing will include a small electrical stimulus’.

2The second part of the test is performed by a physician specializing in EMG testing. This is a needle electrode examination. A thin gauge needle is used similarly to a microphone that monitors and measures the electrical activity in muscles.

Why Do Patients Have EMG Tests?

Electromyography tests have the potential to aid the doctor in distinguishing the cause of an array of medical conditions such as numbness, paralysis, muscle spasms, and various causes of pain.
