Pain, weakness, tingling and numbness — all of these symptoms can be caused by problems with nerves or muscles, and they can be physically disabling. Electrodiagnostic tests reveal how well your nerves and muscles are working and determine the existence, type and extent of any damage. Identifying the exact source of pain is an important step toward restoring your health. Doctors at NJPR are able to perform today’s most advanced diagnostic procedures and are committed to finding answers that will relieve your pain.
The human body has been likened to an electrical generator. In particular, nerves and muscles create electrical signals that deliver messages to and from your brain.
Damage to nerves and muscles can slow or stop the travel of these electrical signals. If you have pain, weakness or numbness in your back, neck or limbs, measuring the electrical activity in your nerves and muscles can help your doctor make a proper diagnosis. Electrodiagnostic testing measures the speed and strength at which electrical impulses travel within and between nerves and muscles. A damaged nerve or muscle will transmit a weaker and slower electrical signal.
Electrodiagnostic testing often is divided into the following two parts, conducted during the same session:
Electrodiagnostics (Measuring the electrical activity in muscles and nerves) can help find diseases that damage muscle tissue (such as myopathy and muscular dystrophy) or nerves (such as amyotrophic lateral sclerosis or peripheral neuropathies). The results of EMG/NCS testing can be an invaluable tool for your doctor to determine various conditions that can affect your nerves and muscles, which will help them manage your care more effectively.
Electrodiagnostics are safely performed in a sterile, office-based setting. Depending on the symptoms and the number of nerves and muscles to be tested, the tests can take from 15 minutes to two hours or more. Patients are advised not to wear lotion on their skin on the day of testing, as this will interfere with the ability to obtain data.
Patients typically return to work or normal activities following a study. The information provided by this diagnostic tool can help determine the most effective treatment approach for chronic pain caused by damaged nerves and muscles.
Pain, weakness, tingling, and numbness – all of these symptoms can be caused by problems with nerves of muscles.
