Electromyography (EMG) in Satna

Electromyography (EMG) in Satna electrodiagnostic testing is a diagnostic test to find out the function of skeletal muscles and the nerves. Every movement in the body from smallest to biggest it involves complex communication between central nervous system, nerves and muscles. During movement, motor nerves send electrical signals to the muscles. An electromyography (EMG) can find out the problem with motor nerves, muscles or the communication between the two.

Sometime neurologist performs an EMG test as well as nerve conduction study.Nerve conduction study measures the flow of electrical current in a nerve before it reaches a muscle also measures the response of muscles to electrical signal and how much muscle contraction produces. Doctor recommends this test if patients having symptoms like muscle weakness or numbness and tingling.

An Electromyography (EMG) test helps to diagnose the several injuries or diseases that affect motor nerves and muscles. There are some conditions where EMG can help to diagnosis such as peripheral neuropathy, nerve compression syndrome, carpal tunnel syndrome, pinched nerves, sciatica, muscular dystrophy, polymyositis, dermatomyositis and myasthenia gravis.

How Electromyography (EMG) in Satna test work:

To understand working of EMG test, first understand how muscles work. the motor nerves or motor neurons which is originate from the brain, send electrical signals to muscles to do some work which is traveling through the spinal cord, through motor nerves to muscles. Because of this electrical stimulation electrical activity form in the muscles, and help to them to contract or tighten.

In electromyography, doctor inserts a small needle in the muscles with an electrode to record its electrical activity. A doctor doesn’t deliver electrical stimulation through the needle it is only a recording device. When body is at rest or contract muscle, the needle electrode records the electrical activity. The needle is attached through a cable to a computer and doctor can see the movements when the body is at rest or during the contract the muscles. The monitor shows in the form of waves. If the muscle is damaged the monitor show the abnormal electrical activity during resting and contracts. Doctor analyses this wave according to the sign and symptoms of the patients.

Preparation for an EMG test:

Some steps should be followed before or during the EMG test:

Bathe or shower and wear comfortable cloths.
Avoid putting cream, lotion or perfume on the skin.
If patient taking a blood thinner medication should tell the doctor before the test, blood thinner medication increases the risk of bleeding after an EMG.
If patient have pacemaker or any other electrical medical device should tell the doctor before the test.
In some cases, cigarette smoking, drink caffeinated beverages, such as coffee or tea interfere in the test.

The test generally takes 60 to 90 minutes but it depends on number of muscles that needs to test. This is not a painful test but some patients may feel some pain or discomfort during inserting the needle into the skin and muscles. Some patients feel tender in the muscles for few days.

You may feel some pain or discomfort when your provider inserts the needle into your skin and muscles. But most people can complete the test without issues.

After the test, the muscles they tested may feel tender for a few days.

How long does an Electromyography (EMG) in Satna test take?

The test usually takes 60 to 90 minutes. It depends on how many muscles your provider needs to test.
