Nothing is more important than precisely diagnosing nerve and muscle disorders, and the only way to do that is with advanced nerve testing like electromyography. Leslie Zuniga, MD, and the team at the Center for Neurology and Spine in Phoenix, Arizona, have advanced training and experience in nerve testing, obtaining accurate information supporting the right diagnosis and allowing them to create a personalized treatment plan that eases your symptoms and restores optimal function. Call the office today or book online if you have questions about nerve testing or need to schedule electromyography.
Electromyography (EMG) is a diagnostic test measuring electrical activity between nerves and muscles. The team typically performs EMG with a second diagnostic test, a nerve conduction study (NCS).
Nerve testing with EMG and NCS helps diagnose problems by:
Your provider may also use nerve testing to evaluate disease progression.
Your Center for Neurology and Spine provider recommends electromyography to identify the cause of nerve- and muscle-related symptoms like pain, tingling, numbness, spasms, and weakness.
Nerve testing helps your provider diagnose many muscle and nerve conditions, including:
The Center for Neurology and Spine has a proven record of accurately diagnosing these and other neurological conditions using EMG and NCS.
The Center for Neurology and Spine values each patient, explaining the procedure and answering questions before moving forward. However, these are the basics of EMG and NCS procedures:
Your provider inserts thin needles into a specific muscle (the one exhibiting weakness, spasms, or other symptoms). The needles contain small electrodes that pick up nerve signals as you tighten and relax the muscle, revealing nerve disorders such as muscular dystrophy, myasthenia gravis, and amyotrophic lateral sclerosis (ALS).
A nerve conduction study reveals how well electrical signals travel through a specific nerve. Your provider places electrodes on your skin above the nerve. Then, they use an electrode at the end of the nerve to send a mild electrical impulse, triggering a signal that travels through the nerve.
Other electrodes pick up the electrical activity along the nerve, providing information about the strength and speed of the signal. NCS diagnoses conditions like diabetic neuropathy, peripheral nerve injuries, and carpal tunnel syndrome.
