As the name suggests an electromyogram or an EMG is a diagnostic procedure which helps in detecting the electrical activity of the muscles of the human body. The muscles of the human body are regulated by neural or nerve stimulation. In case where the muscles are not stimulated appropriately, chances are there could be an abnormality.
When is an electromyogram advised ?
An electromyogram is advised to check the normal activity of the muscles or when there is an abnormality. Below are the few mentioned cases where an electromyogram is advised.
- Weakness of muscle
- Tingling sensation
- Numbness
- Muscle pain
- Reduction in functionality of muscle
- Paralysis of any muscle or side of the body
Following are certain muscular disorders which can be diagnosed with the help of Electromyogram.
- Myasthenia Gravis
- Muscle Dystrophy
- Carpal Tunnel Syndrome
- Lateral Sclerosis
- Poliomyelitis
- Disc Hernia

What happens during an electromyogram ?
You will be made to lie down on an examination table and the neurologist will place the surface electrodes on the area or the muscle to be examined. Sometimes small needles might be inserted in the areas where the muscle activity needs to be recorded. You might feel a slight prickly sensation if the electrodes are being inserted. The neurologist records your muscle movements and a report is generated by the end of the test depending upon the electrical activity of your muscle which is being tested.
What are the risks and complications of an electromyogram ?
