About this test

EMG checks the electrical activity of muscles and how they respond to nerve stimulation. It helps identify nerve or muscle problems behind weakness, cramps or pain.

EMG is often done together with NCV. A fine needle electrode may be used; tell the technician if you take blood thinners.

Who it is for

• Muscle weakness or wasting
• Cramps, twitching or unexplained pain
• Suspected pinched nerve or muscle disorder

How to prepare

• Do not apply lotion or oil on the limb to be tested
• Keep the limb warm
• Tell us about blood thinners, pacemakers or implants

What EMG tells your doctor

Electromyography (EMG) checks how muscles and the nerves that control them work. When a nerve sends a signal, the muscle produces a small electrical activity. EMG records that activity at rest and during gentle contraction.

The test helps find the cause of muscle weakness, wasting, cramps, twitching, numbness or pain. It can show whether the problem is in the muscle itself, in the nerve, or where the nerve leaves the spine, and how severe it is. EMG is often done together with nerve conduction velocity (NCV) for a complete picture.

How the test is done

• The technician cleans the skin over the muscle to be tested.
• A very fine needle electrode is inserted into the muscle. You may feel a brief pinch or cramp-like discomfort.
• You are asked to relax the muscle and then tighten it gently, so that the signals can be recorded at rest and during movement.
• Several muscles may be tested depending on your symptoms. The test usually takes 30 to 60 minutes.

Before you come

• Do not apply lotion, oil or cream on the limb to be tested.
• Keep the limb warm; a cold limb can change results.
• Tell us if you take blood thinners, have a bleeding disorder, a pacemaker or other implanted device, or have a skin infection near the test area.
• Take your medicines as usual unless your doctor says otherwise, and bring earlier reports and scans.

After the test

You may have mild soreness or a small bruise where the needle went in. Most people resume normal activity at once. Contact your doctor if you notice increasing pain, swelling or redness. The report is interpreted by your doctor with your symptoms and examination.

What is an electromyography?

Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of your muscle. The test is used to help detect nerve and muscle problems.

During the test, your doctor will insert one or more small needles (also called electrodes) through your skin into your muscle. The electrical activity picked up by the electrodes is then displayed on a monitor in the form of waves. An audio-amplifier is used so the activity can be heard.

EMG measures the electrical activity of your muscle during rest, slight contraction, and forceful contraction. Muscle tissue does not normally make  electrical signals during rest. When an electrode is inserted, a brief period of activity can be seen, but after that, no signal should be present.

 

After all of the electrodes have been inserted, you may be asked to contract your muscle, for example, by lifting or bending your leg. The action potential (size and shape of the wave) that this creates on the monitor give information about the ability of your muscle to respond to nerve stimulation. As your contract your muscle more forcefully, more and more muscle fibers are activated, producing action potentials.

A healthy muscle will show no electrical activity (no signs of action potential) during rest, only when it contracts. However, if your muscle is damaged or has lost input from nerves, it may have electrical activity during rest. When it contracts, its electrical activity may produce abnormal patterns.

An abnormal EMG result may be a sign of a variety of muscle or nerve disorders, including:

1. Polymyositis (an inflammatory muscle disease that causes decreased muscle power)
2. Muscular dystrophy (a chronic genetic disease that progressively affects muscle function)
3. Myasthenia gravis (a genetic or immune disorder that occurs at the point where the nerve connects with the muscle)
4. Myotonic (stiff) muscles

A related test that may be done is a nerve conduction velocity (NCV) test. This is also called a nerve conduction study (NCS). NCV is a measurement of the speed of conduction of an electrical impulse through a nerve. NCV can determine nerve damage and destruction, and is often done at the same time as EMG. Both tests help detect the presence, location, and extent of diseases that damage the nerves and muscles.
Why might I need an EMG?
EMG is often used along with nerve conduction velocity (NCV) to tell the difference between a muscle problem and a nerve problem. NCV detects a problem with the nerve, whereas EMG can detect a problem with the muscle.

EMG may be done to find the cause of symptoms, such as muscle weakness, deformity, stiffness, and shrinkage. It may be used to detect whether someone is having true muscle weakness or weakness because of pain or psychological reasons.

EMG may be used to evaluate many problems or disorders, including:

1. Neuromuscular diseases, such as myasthenia gravis
2. Motor problems, such as involuntary muscle twitching
3. Nerve compression or injury, such as carpal tunnel syndrome
4. ANerv_20140108_v0_001
5. Nerve root injury, such as sciatica
6. Muscle degeneration, such as muscular dystrophy

Yes. Our trained technician visits with portable equipment. Share your address on WhatsApp and we confirm the visit slot with you.

Do I need a doctor's prescription?

A prescription helps us run the right test, but you can also book on your own for a routine check. Send a photo of the prescription on WhatsApp if you have one.

Is EMG painful?

Most people feel brief, mild to moderate discomfort when the needle is inserted and during muscle contraction. It settles soon after the test.
