Diagnostic tests are a critical aspect of identifying the root cause of a neurological concern. The information these tests provide allows physicians to create a treatment plan that addresses a patient’s specific needs. The NY Neurology Associates team works to provide each patient with detailed information about the testing process so that they are fully prepared.
An EMG or electromyogram is used to measure how much electrical activity your muscles have both when they are at rest and when they are contracted. These tests are often used to:
There are two ways of doing an EMG: either by placing electrodes on the skin over the muscle in question or by placing a needle directly into the muscle. The EMG is then able to detect and record all of the information about the movement of the electrical activity. The results from the EMG can help to pinpoint if an issue is caused by an issue with the muscle, with the nerve or with the junction between the two.
Nerve conduction studies, or NCS, measure how efficiently nerves transmit signals from the brain to the muscle. These studies may be done with EMG. Uses for NCS include:
To do an NCS, an electrode is placed directly over the nerve in question. A second monitoring probe is also added that allows doctors to record how well the nerve is doing in communicating with the body. The reaction times are closely monitored to determine if there is nerve damage.
Nerve Conduction Velocity or NCV looks at specific feedback on nerves that are performing abnormally. This test is done with EMG in order to identify how well the nerves are conducting electrical activity. Uses for NCV include:
To do the test, an electronic pulse is sent to a nerve. The nerves are monitored to determine how fast the message can be passed along the passageway of nerves.

Below are some common questions about nerve conduction tests and electromyography, with answers taken directly from the article.
An EMG or electromyogram is used to measure how much electrical activity your muscles have, both when they are at rest and when they are contracted.
These tests are often used to identify issues with the muscles, nerves, or the areas between muscles and nerves. They can also be used to understand and address the root cause of feeling numb, weak, or having spasms in the muscles.
To do an NCS, an electrode is placed directly over the nerve in question. A second monitoring probe is also added that allows doctors to record how well the nerve is doing in communicating with the body. The reaction times are closely monitored to determine if there is nerve damage.
Uses for NCV include the diagnosis of nerve damage and evaluating diseases of the nerves or muscles.
