![]() How Is A Nerve Conduction Study Performed?Įlectrode patches are applied to the surface of the skin at different locations where the targeted nerves are located. Furthermore, this type of diagnostic test, especially in combination with electromyography, has been shown to be the most reliable and accurate in terms of diagnosing muscular and nerve diseases. ![]() Research indicates that when a nerve-related problem or disorder is suspected, a thorough medical evaluation should include a nerve conduction study. Furthermore, MRIs and CT scans are time consuming and costly procedures that do not always provide physicians with accurate information regarding nerve and muscular conditions. This often causes nerve-related health problems to be misdiagnosed or undiagnosed. However, certain types of nerve damage cannot be seen on an MRI or CT scan. Imaging technology such as computed tomography (a CT scan) or magnetic resonance imaging (MRI) is often initially performed when nerve damage such as a pinched nerve or nerve root is suspected. Both of these procedures are used to help physicians evaluate the presence of a nerve or muscular disease, its location if a disease is present, and the extent of its progression. This test is usually performed along with electromyography (EMG), which is a diagnostic test that assesses a nerve’s ability to transmit electrical signals to muscles and how well the muscles respond. Nerve damage may indicate the presence of a muscular or nerve disease or a traumatic injury. The purpose of a nerve conduction study is to determine whether nerve destruction or damage has previously occurred. Want to learn more about nerve conduction studies?

Military and DVA patients also do not have out of pocket expenses. Workers compensation and transport accident patients require prior approval from their insurer, and do not have out of pocket expenses. The out of pocket costs therefore vary, and will be estimated at the time you book your appointment. How much will it cost?Ī Medicare rebate is available for the study and varies depending on the complexity of the study and the number of nerves examined. Frequently a clinical examination is performed at the same time to add further diagnostic value. Typically, they take between 15 minutes and an hour, depending on the number of sites requiring testing and the complexity of the clinical presentation. These tests are performed at a Precision Brain, Spine & Pain Centre consulting location, by one of the specialists. Where are nerve conduction studies & electromyography performed & how long do they take? ![]() You may continue to take all of your usual medications before and after the tests. You can return to normal activities such as work, driving and sports immediately afterwards. In colder environments, the arms or legs may need warming as cool peripheries slow the conduction velocity of nerves and may affect the results. You should avoid topical creams as these may increase skin resistance to the applied current, and therefore require stronger levels of electrical stimulation. What precautions should I take beforehand? Most patients describe the feeling as a ‘tingling’ or ‘tapping’ sensation. Long term side effects occur rarely, if ever. Patients typically experience only minor discomfort. Nerve conduction studies are safe and generally well tolerated. carpal tunnel syndrome, ulnar neuropathy & other compressive nerve conditions.Nerve conduction studies and EMG can often diagnose a variety of conditions including: ![]() EMG is often done at the same time, and is a way of recording the electrical activity produced by muscles. The strength of the impulse and the speed at which it travels are examples of a number of characteristics measured. Surface electrodes (small thin metallic discs) are used to deliver and detect the electrical impulses. Nerve conduction studies are electrical tests which involve the stimulation of nerves along several points (usually as they run down the arms or legs).
