What is EMG/NCV Testing?
Electromyography (EMG) and Nerve Conduction Velocity (NCV) testing are advanced diagnostic studies used to evaluate nerve and muscle function.
Electromyography (EMG) is a diagnostic procedure that measures the electrical activity of your muscles. Small, thin, sterile needle electrodes are gently inserted into specific muscles by a trained physician. These electrodes detect how your muscles respond at rest and during contraction.
This test helps determine whether muscle weakness, pain, or numbness is due to a muscle disorder itself or a nerve problem supplying the muscle.
Conditions EMG can help diagnose include:
Carpal tunnel syndrome
Radiculopathy (pinched nerves in the neck or back)
Peripheral neuropathy (nerve damage often from diabetes)
Muscle inflammation (myositis)
Motor neuron diseases (like ALS)
What patients should know:
You may feel a quick pinch during needle placement and mild muscle soreness afterward, but most patients tolerate the test well.
The test usually lasts 20–40 minutes, depending on how many muscles are tested.
No special preparation is needed, but let your doctor know if you are on blood thinners or have a pacemaker.
Nerve Conduction Velocity (NCV), also called a nerve conduction study, evaluates how quickly and effectively electrical signals travel through your nerves. This test is often performed along with EMG for a complete nerve and muscle evaluation.
During NCV testing, small electrodes are placed on the skin over specific nerves. A mild electrical pulse is delivered to stimulate the nerve, and sensors record how fast and strong the signal travels.
Conditions NCV can help diagnose include:
Carpal tunnel syndrome and ulnar neuropathy
Peripheral neuropathy (nerve damage from diabetes, alcohol use, or chemotherapy)
Guillain-Barré syndrome and other demyelinating neuropathies
Nerve injuries from trauma or compression
Sciatica or herniated discs affecting nerve function
What patients should know:
You may feel a brief tingling or tapping sensation during stimulation.
The test typically takes 15–30 minutes, depending on how many nerves are studied.
There are no lasting side effects, and you can resume normal activities immediately.
