EMG FULL FORM

Full Form of EMG : Electromyogram

What is the full form of EMG?

No:1. EMG stands for Electromyogram.
No:2. It is a diagnostic test which is performed to record the electrical activity of muscles at rest and during contraction.
No:3. It evaluates the health of muscles and nerve cells that control them.
No:4. The nerve cells which are called motor neurons send electrical signals (impulses) to muscles that allow muscles to contract.
No:5. EMG tests how well your muscles respond to electrical signals received from nerve cells (motor neurons).
No:6. The EMG translates these electrical signals into graphs, numerical values etc that are interpreted by the specialist.

EMG Test

In this test, electrodes are used to transmit or detect electrical signals.
This test has two components: Nerve conduction study and Needle EMG.

No:1. Nerve conduction study

a). It is the first part of this test in which electrodes are placed on the skin to measure the movement and strength of impulses moving between two or more points.
b). It evaluates the ability of nerve cells to send electrical impulses to their respective muscles.

No:2. Needle EMG

a). In this part of the test, a needle electrode is insert directly into a muscle to record and evaluate electrical activity of that muscle during contraction and rest.
b). It acts like a microphone inserted into the muscle.

Symptoms

A doctor usually suggests EMG when a person shows the symptoms of a muscle or nerve disorder such as:
No:1. Numbness
No:2. Tingling
No:3. Muscle weakness
No:4. Muscle pain or cramping
No:5. Paralysis
No:6. Tics ( involuntary muscle twitching)
Its results help doctor diagnose nerve disorders, muscle disorders, and other disorders that affect the coordination between nerve cells and muscles such as:
No:1. Nerve damage due to disk compression in the neck or back
No:2. Nerve compression from carpal tunnel syndrome
No:3. Neuromuscular diseases like amyotrophic lateral sclerosis (ALS), muscular dystrophy, poliomyelitis etc.
No:4. Peripheral neuropathy
