If I have a back injury why are EMG test done in the legs?Legs hurt but the back burns,spams and hurts.?

Question

I fell and damaged the muscles and nerves in the back which effects the legs I know but the back has never been tested when doing an EMG. Do they do EMG testing of the back?

Sorry, I forgot to mention that I have 4 disc involed along with nerve and muscle damage. Both of the EMG test were done in the legs and were negitive. MRI shows the disc protrudeing and spinail stenois

Answer 1

EMG is used to test the muscles and the MRI is used to see your spine. An MRI does not have to be done at the same time as the EMG.

Below is an article discussing what an EMG actually does.

What is an electromyogram?

An electromyogram (EMG) is a test that is used to record the electrical activity of muscles. When muscles are active, they produce an electrical current. This current is usually proportional to the level of the muscle activity. An EMG is also referred to as a myogram.

EMGs can be used to detect abnormal muscle electrical activity that can occur in many diseases and conditions, including muscular dystrophy, inflammation of muscles, pinched nerves, peripheral nerve damage (damage to nerves in the arms and legs), amyotrophic lateral sclerosis (ALS) (also known as Lou Gehrig disease), myasthenia gravis, disc herniation, and others.

Why is an EMG test done?

An EMG is most often performed when patients have unexplained muscle weakness. The EMG helps to distinguish between muscle conditions in which the problem begins in the muscle and muscle weakness due to nerve disorders. The EMG can also be used to detect true weakness, as opposed to weakness from reduced use because of pain or lack of motivation.
