Electromyography (EMG) is a valuable test that monitors and records nerve activity in your muscles. The board-certified neurologists at Integrated Neurology Services provide EMGs at four clinics located in four Northern Virginia locations in Alexandria, Falls Church, Lorton, and Reston, to diagnose conditions like neuropathy and radiculopathy. If you have abnormal muscle twitching or numbness, call Integrated Neurology Services or make an appointment for an EMG online today.
An EMG monitors, measures, and records the nerve activity in your muscles. EMG testing can help your doctors diagnose nerve and muscle dysfunction and the conditions that cause it. EMGs are minimally invasive and use needle electrodes to assess the health of your muscle and nerve fibers.
The doctors at Integrated Neurology Services often combine EMGs with nerve conduction velocity (NCV) studies, which measure the strength and speed of electrical signals as they travel between two or more points. An NCV uses sticky electrodes that are applied to the surface of your skin.
Your doctor might suggest an EMG if you're having symptoms, such as numbness, tingling, and muscle cramping. An EMG can also provide information on what could cause a muscle twitch or paralysis. An EMG can help identify a wide range of conditions, including:
If your doctor is concerned about your symptoms, they may recommend EMGs and NCV to collect more information about your nerve function. They explain the tests, how they work, and what information they can provide. Your doctor can answer any questions about an EMG during your consultation.
Your doctor gives you specific instructions on how to prepare for your EMG during your consultation. Make sure they know if you have a pacemaker, implantable defibrillator, or a bleeding disorder.
Before your test, you should shower, but not apply any lotions or oils to your skin, as these substances can interfere with your results. You should also wear comfortable clothing and avoid using tobacco for at least three hours before your appointment.
You might need to change into a hospital gown for your EMG. They usually begin with the noninvasive NCV study. Then, while you rest on a treatment table or a reclining chair, your doctor or a technician places the electrodes into the body part where you have symptoms. You might feel a slight pinch when the needles are inserted, but once they're in place, you shouldn't feel them.
An EMG usually takes around an hour and provides your doctor with valuable information about your nerve function and muscle fiber health.
If you need an EMG or are concerned about unexplained tingling, numbness, or cramping, call Integrated Neurology Services or make an appointment for an EMG online today.
