What to Expect From Nerve Conduction Studies

If you’re experiencing shooting pains and numbness and tingling in your neck, lower back, wrist or legs, don’t be surprised if you’re doctor recommends a nerve conduction velocity (NCV) test – also known as a nerve conduction study.

How Nerve Conduction Velocity Tests Work

NCV’s are tests that measure how quickly an electrical impulse moves through your nerve and whether the nerve is, in fact, damaged. Here’s how it works: two electrodes are applied to the skin over your nerve. One stimulates the nerve with a mild electrical impulse, the other records it, while another electrode records the electrical activity. The process is then repeated for each nerve that is being tested.

The speed of the electrical impulse is calculated by measuring the distance between the electrodes and how long it takes for the impulses to travel between them.

As part of the nerve conduction study, another test that may be performed simultaneously is called an electromyography (EMG), which measures the electrical activity in your muscles. An EMG can detect whether the muscle is functioning properly in response to the nerve’s stimulus.

Diagnosing Conditions with Nerve Conduction Velocity Tests

By combining NCV and EMG tests, your physician can better tell whether you’re suffering from a nerve disorder or a muscle disorder and pinpoint the specific disease or condition. These may include:

An NCV procedure is conducted by a neurologist or pain specialist who specializes in nerve disorder and is often assisted by a technologist. The study may be done on an outpatient basis or as part of a hospital stay, depending on your condition and your doctor’s practices.

After the Procedure

After the non-invasive procedure, you may return to your normal activities, although your physician may advise you to avoid strenuous activities for the remainder of the day and provide you with other instructions, depending again on your situation.

Pinched Nerve

A pinched nerve can occur when the tissues around it put the nerve under pressure. Bone, cartilage, tendon, or muscle pressing on a nerve can cause it to malfunction, resulting in pain, weakness, tingling sensations, or numbness.
