Comprehensive EMG & NCV Services at Eskag Sanjeevani Hospital

If your doctor has advised an EMG, NCV, or combined EMG NCV test, get your recommended nerve and muscle testing at Eskag Sanjeevani Hospitals, Kolkata. Our facility provides EMG and NCV testing with access to hospital-based neurological care.

Our EMG and NCV services help assess nerve and muscle function and support doctors in finding the cause of symptoms such as numbness, tingling, weakness, and persistent limb pain.

EMG and NCV Testing at Eskag Sanjeevani Hospitals

An EMG NCV test combines two related assessments:

• Electromyography (EMG): It is a test that records the electrical activity of muscles. It helps assess how muscles are working and whether symptoms may be linked to nerve or muscle problems.
• Nerve Conduction Velocity (NCV): This test measures how quickly electrical signals travel through the nerves. It can help identify nerve damage, compression, or other changes in nerve function.

Generally, a combined EMG and NCV test takes 40 to 90 minutes to complete; however, the exact duration might vary depending on the requirements.

Here’s a detailed breakdown of the time associated with the EMG NCV Test.

What Happens During the Electromyography Procedure?

During NCV testing, small electrodes are placed on the skin, and mild electrical signals are used to assess nerve responses.

Before the test:

You may be asked to change into clothing that allows easy access to the area being tested. The skin should be clean and free from creams, oils, or lotions, as these can affect electrode contact. Tell the medical team about any medicines you take, especially blood thinners, and inform them if you have a pacemaker or other implanted electrical device.

During the test:

For an NCV test, small electrodes are placed on the skin over selected nerves and muscles. A mild electrical impulse is delivered to the nerve, and the electrodes record the nerve responses.

During EMG, a fine needle electrode is inserted into selected muscles to record their electrical activity.

After the test:

You can usually return to your normal activities after the test, unless your doctor or the medical team advises otherwise. You may have mild soreness or bruising at the needle insertion sites after EMG, which generally settles on its own.

Is the EMG NCV test painful? No. Most people feel mild tingling or a quick pinch. It’s over fast, and you can go straight back to your normal daily routine.

Factors Affecting Nerve Conduction Velocity

• Age: Nerve conduction velocity and signal amplitude may naturally decrease with age.
• Body temperature: Cold skin can slow nerve conduction and prolong response latencies.
• Height: Taller individuals may have longer nerve pathways, which can increase conduction time.
• Diabetes: Long-term high blood glucose can damage peripheral nerves and contribute to diabetic peripheral neuropathy.
• Poor glucose control: Persistently elevated blood glucose may be associated with slower nerve conduction and reduced signal strength.
• Abnormal blood lipid levels: Metabolic changes in blood lipids may increase the risk of peripheral nerve dysfunction.
• Obesity: Higher body weight is associated with an increased risk of peripheral neuropathy, particularly in people with diabetes.
• High blood pressure: Hypertension may also be associated with a higher risk of peripheral nerve damage.
• Kidney problems: Reduced kidney function and raised urea levels can affect nerve function and may influence nerve conduction measurements.

When Do You Need an EMG/NCV Test?

• Numbness, tingling, or burning
• Muscle weakness, cramps, or unexplained pain
• Nerve compression or injury
• Peripheral neuropathy
• Spine-related nerve symptoms
