Are you experiencing unexplained numbness, tingling, burning pain, or weakness in your arms, legs, hands, or feet after a work or auto accident? Electromyography (EMG) and Nerve Conduction Velocity (NCV) tests help pinpoint the source of these symptoms. At Advantage Healthcare, we perform these diagnostic tests to assess the health of your nerves and muscles, providing crucial information to guide your treatment plan.
What Problems Does EMG/NCV Testing Address?
These tests help diagnose conditions such as:
- Pinched Nerves (Radiculopathy): Nerve irritation or compression as nerves exit the spine (common after neck/back injuries).
- Peripheral Neuropathy: Damage to nerves outside the brain and spinal cord.
- Nerve Entrapment Syndromes: Conditions like Carpal Tunnel Syndrome (wrist) or Cubital Tunnel Syndrome (elbow).
- Muscle Diseases (Myopathies): Although less common in this context, EMG can help identify primary muscle disorders.
- Investigating symptoms like numbness, tingling, burning, weakness, cramping, or muscle twitching.
How Does EMG/NCV Testing Work?
The test usually has two parts:
Nerve Conduction Velocity (NCV)
Small electrode patches are placed on your skin over nerves. Mild electrical impulses are delivered to stimulate the nerve, and other electrodes record how quickly the signal travels. This measures nerve health and speed.
Electromyography (EMG)
A very fine needle electrode (like an acupuncture needle) is inserted into specific muscles. You’ll be asked to relax and gently contract the muscle. The needle records the electrical activity within the muscle, assessing muscle health and its nerve connection.
What Are the Benefits of EMG/NCV Testing?
- Accurate Diagnosis: Helps identify if nerves or muscles are the cause of your symptoms and locate the problem area.
- Guides Treatment: Results help your doctor choose the most effective treatments (e.g., specific therapies, injections, or determining if surgery might be indicated).
- Provides Objective Data: Offers measurable information about nerve and muscle function, which can be important for your case.

Frequently Asked Questions
Does EMG/NCV testing hurt?
The NCV involves mild electrical sensations that some find slightly uncomfortable but not typically painful. The EMG needle insertion can feel like a small pinch or pressure, and muscle contractions might cause brief discomfort. Most patients tolerate the tests well.
How long does the test take?
Depending on the number of limbs or areas being tested, it usually takes between 30 to 90 minutes.
How should I prepare for the test?
Generally, avoid using lotions or creams on your skin on the day of the test. Inform the examiner about any blood-thinning medications or pacemakers. Wear clothing that allows easy access to the areas being tested.
When will I get the results?
A report interpreting the findings will be sent to your referring physician, typically within a few business days. Your doctor will then discuss the results with you.
