In addition, it does this by looking at how well the electrical currents in the nerves transmit to the muscles. In short, an electromyogram (EMG) looks at the function of the nerve roots leaving the spine. Because of this, the doctor may order an electromyogram or EMG to look at the nerve roots to determine their working condition. Syed, MD, Shyam Kishan, MD, and Kathryn Wiesman, MD, will need to order extra testing to diagnose or help devise a treatment plan. The typed EMG results can be faxed to your doctor several hours after the test.Sometimes, our Southwest Scoliosis Doctors, Richard Hostin, MD, Devesh Ramnath, MD, Ishaq Y. The verbal results of the test can be provided to the patient is at the conclusion of the test.
When can I expect the results of the test? 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. The doctor will evaluate different nerves in the extremity, protocols vary, but be prepared to have about 4-6 nerve stimulated. The first part of the test requires the doctor to isolate specific nerves with precisely placed electrodes and then he /she will provide a low voltage electrical stimulus to activate or depolarize the nerve. On the day of the test, take a shower to remove body oil and do not use body lotion. Tell your health care provider before the test if: Patents that have back pain with lower extremity Pain may have the following: Your doctor may want to exclude the following:

What types of conditions are diagnosed with NCV/EMG: patients that complain of burning pain in the feet, hands or fatigue with minimal exertion are excellent candidates for the test. Patients present with a lot of complaints, but the ones that require a nerve test(NCV/EMG) are those that complain of neck or back pain with radiating pain in the arm or legs, muscle weakness or involuntary twitching of muscles. An electromyogram, or EMG, is a test that checks the response of muscles to messages sent by the nerves. The test has two components, the first is the NCV(nerve conduction test), the second component is the needle examination called an electromyogram. What is an NCV/EMG:Īn NCV/EMG test is a diagnostic test that your doctor may order to assist in obtaining additional information in order to assist him/her in making the right diagnosis regarding your medical condition. 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.
