Electrodiagnostic testing consists of Nerve Conduction Studies (NCS) and / or Electromyography (EMG). These tests allow our physiatrists to evaluate your peripheral nerves and muscles in order to provide detailed diagnostic information which will help identify your diagnosis and optimize the treatment strategy.
NCS measure the ability of nerves to transmit electrical signals whereas EMG measures the electrical activity of muscles at rest and during contraction. Using these techniques, motor and sensory function can be evaluated.
NCS are performed to assess for damage to the peripheral nervous system. This includes the nerves that travel from the spinal cord to your muscles and skin. These studies are used to identify disorders such as Carpal Tunnel Syndrome, Radiculopathy or Guillain-Barre syndrome.
EMG is performed in order to assess for damage in muscles, nerve or at the muscle nerve interface. These problems may include a herniated disc (i.e. sciatica), ALS, muscle inflammation and a variety of other conditions.
To prepare for the test, please ensure the following:
- Wear loose clothing that can be easily rolled up past your elbows and knees;
- Do not apply any skin moisturizer or creams on the day of your appointment;
- Avoid smoking and caffeine (coffee/tea/cola/chocolate) for 2-3 hours prior to your appointment;
- Inform the physician if you are on any blood thinners (Coumadin/Warfarin/Heparin)
