NCS and EMG testing typically takes 30 to 60 minutes to complete, depending on complexity of the diagnosis, and is performed at our office. Patients report that sometimes this test can be uncomfortable, but is not considered painful. Most of our patients complete the test with no discomfort at all. Nerve conduction study involves a series of mild electric pulsations, on the surface of the skin, that stimulate nerves to conduct a response to electrodes which are also placed on the skin surface.
The integrity and speed with which the nerves carry the signals are measured and compared to normal minimum standard values and/or compared left to right side. Electromyography is the second part of the test that involves a tiny needle that is inserted into selected muscles; similar to acupuncture. You will be asked to relax and then to contract your muscles, which generates an electric signal which is carried into the needle and analyzed by a computer software oscilloscope.
It would be best for you to wear loose-fitting comfortable clothing, and best to wear shorts and a short-sleeved shirt. Please do not use any creams, oils or lotions of any kind on the day of your test. Your skin, particularly hands and feet, should be washed with soap and warm water prior to arrival for testing.
You may eat and drink as usual on the day of the test. You may also take your routine medications. The test is not harmful in any way. Results are typically reviewed with you upon completion of the study.
