Electromyography (EMG) is a diagnostic test that helps detect neuromuscular abnormalities by measuring electrical activity in the muscles.
During an EMG test, a very thin needle (electrode) will be inserted through the skin and into the muscle. Once the electrode is in place, the patient will be asked to either contract their muscles or keep their muscles relaxed. The electrode will detect electrical activity and results will be displayed on a nearby monitor (oscilloscope).
A nerve conduction velocity (NCV) test is often performed at the same time as an EMG. An NCV helps to differentiate a nerve disorder from a muscle disorder.
The Brigham and Women’s Hospital (BWH) Division of Neuromuscular Disease and Electromyography (EMG) provides comprehensive diagnostic evaluation, consultation, and management of all neuromuscular disorders, including motor neuron disease (ALS), peripheral neuropathies, myopathies, muscular dystrophy, and myasthenia gravis.
Currently, we offer comprehensive neuromuscular services, including EMG, at the main BWH campus in Boston and EMG and other diagnostic services at Brigham and Women's/Massachusetts General Health Care Center.
Specialists at the Division of Neuromuscular Disease and Electromyography use EMG tests to diagnose a wide variety of neuromuscular diseases, motor problems, nerve injuries, or degenerative conditions, such as:
Typically, not a lot of preparation is necessary for an EMG.
The Brigham and Women’s Hospital Department of Neurology comprises a diverse yet integrated array of specialized clinical services, including inpatient and outpatient evaluation and management, second opinions for complex cases, diagnostic testing, and care for the most critically ill. This collaborative approach enables our team to provide patients with all the care they need in one location, providing a greater measure of safety, convenience, and satisfaction.
BWH has long been committed to not only the care of our patients but also the many other needs that they and their families have. This philosophy of patient- and family-focused care – involving systems and services that emphasize healing in a comfortable, relaxed environment – is a guiding force behind the care we provide at the Department of Neurology.
Brigham and Women’s Hospital is committed to providing all of our patients with the safest, highest-quality, most-satisfying care possible and following established protocols that have been shown to improve patient outcomes. Our inpatient satisfaction survey, sent to patients to assess their total care experience, helps us to monitor what we are doing well and what areas may need improvement. We pride ourselves in the quality of patient care we provide and how we compare with other hospitals.
The Department’s multidisciplinary staff of more than 65 clinical faculty and over 350 department members strives to provide patient-focused, world-class medical care for the entire spectrum of neurological diseases. We have a strong focus on developing new treatments and cures for neurologic diseases, and we offer a variety of teaching programs that train the next generation of neurology professionals.
