Generally, the NCV/EMG takes between 30 minutes to 1 hour depending on how many nerves are being tested.ĭo not wear any lotions or oils on the skin. There is a potential for a small amount of discomfort during the test, but this is usually temporary and well tolerated.

The computer and speaker help the doctor identify if there is any damage present to the nerve of muscle. Electromyography: A small wire is inserted into the specific muscle being tested and connected to a computer and speaker. A very small amount of electrical stimulation is applied over the nerve and the response is recorded and measured for comparison to healthy nerves.Ģ.

These are then connected to a computer that helps measure the electrical signals. Neve Conduction Test: Small sensors are placed on the skin at the site of the nerve being tested. Muscle Disorders attributed to genetic, metabolic, or autoimmune related conditions.ĭoctors often refer their patients for an EMG/NCS when numbness, tingling, burning pain, loss of sensation, muscle weakness, the skin is painful to touch, or muscle fatigue is present.ġ. Peripheral Neuropathies that can be associated with diseases that affect multiple nerves in the body, often times in the hands and feet. Nerve Injuries such as carpal tunnel syndrome, sciatica/radiculopathy, sports injuries, or other trauma-related injuries. In combination, these tests measure the naturally occurring electrical signals within the body, which can help the physician determine if there are any abnormalities present.Ĭommon Conditions evaluated through EMG/NCS's: These two tests are usually performed together, as they help measure the health of nerves and muscles in the body. EMG/NCS's are electrodiagnostic studies that consist of both nerve conduction studies (NCS) and electromyography (EMG).
