Nerve Conduction Study/ Needle EMG Test
The Physiatric Pain and Medical Rehabilitation Clinic clinicians are well trained and have performed countless
numbers of EMG/NCV for private physicians, worker compensation insurance carriers and for our own private patients.numbers of EMG/NCV for private physicians, worker compensation insurance carriers and for our own private patients.
What is an EMG/NCV:
An EMG/NCV test is a diagnostic test that your doctor may order to assist in
obtaining additional information in making the right diagnosis regarding your
medical condition. The test has two components, the first is the NCV (nerve
conduction test), the second component is the needle examination called an
electromyogram. An electromyogram, or EMG, is a test that checks the response
of muscles to messages sent by the nerves.
What type of patient needs an EMG/NCV:
Patients that require a
nerve test (NCV/EMG) are those that complain of neck or back radiating
pain in the arm or legs, muscle weakness or involuntary twitching of muscles. Patients
that complain of burning pain in the feet, hands or fatigue with minimal
exertion are excellent candidates for the test.
What types of conditions are diagnosed with
Patients that have neck pain, hand or
arm numbness or tingling are usually
referred for the test. Your doctor may want to exclude the following:
Patients that have lower extremity pain may
have the following:
How do I prepare for
Tell your health care provider before the test
On the day of the test, take a shower to remove
body oils and do not use body lotion.
How is the test performed?
The first part of the test requires the doctor
to isolate specific nerves with precisely placed electrodes. Then, he /she will
provide a low voltage electrical stimulus to activate or depolarize the nerve.
The doctor will evaluate different nerves in the extremity. Protocols vary, but be prepared to have about
4-6 nerves stimulated.
The second phase of the test is the needle
examination study in which the doctor places a thin needle into 4-6 different
muscles to look for muscle abnormality.
When can I expect the results of the test?
The verbal results of the test can be provided to the patient at the conclusion of the test. The EMG/NCV test results will be faxed to your referring doctor.
