EMGs measure and evaluate the health and functionality of your muscles and nerves. This noninvasive test is performed in two parts – a nerve conduction study and a needle EMG.
During the nerve conduction study, your doctor will attach a series of electrodes to the symptomatic part of your body. These electrodes detect the electrical activity in your muscles to gauge how they communicate with your nerves. For the needle EMG, needle electrodes are inserted into the symptomatic muscles to measure their electrical activity when contracted as well as at rest.
An EEG typically takes 30 to 60 minutes to complete and is performed in the comfort of our office. You’ll spend the duration of the test reclined on a treatment bed or in a comfortable chair.
An EMG enables your doctor to analyze your nerve function and the line of communication between your nerves and muscles. This is a helpful tool in diagnosing many conditions, such as:
It is critical to receive a timely, accurate diagnosis to best treat the underlying causes of nerve problems. If you experience any of the following symptoms, your doctor may order an EMG:
Your neurologist will give you detailed, personalized instructions concerning your medications, so be sure to discuss all of the medications, vitamins and supplements you currently take. Be sure to inform your doctor if you have a pacemaker or implantable defibrillator.
It’s recommended to abstain from smoking in the hours prior to the test. It is also important to shower before the EMG and refrain from applying any creams or lotions. Be sure to wear comfortable clothing.
