Electromyography (EMG) clinic

Electrodiagnosis EDX is a method of medical diagnosis that obtains information about diseases by passively recording the electrical activity of body parts that is, their natural electrophysiology or by measuring their response to external electrical stimuli evoked potentials. Electrodiagnostic medicine also EDX is a medical subspecialty of neurology , clinical neurophysiology , cardiology , and physical medicine and rehabilitation.

The provision of a quality electrodiagnostic medical evaluation requires extensive scientific knowledge that includes anatomy and physiology of the peripheral nerves and muscles , the physics and biology of the electrical signals generated by muscle and nerve, the instrumentation used to process these signals, and techniques for clinical evaluation of diseases of the peripheral nerves and sensory pathways.

In the United States, neurologists receive training in performing needle electromyography and nerve conduction studies during a fellowship in clinical neurophysiology or neuromuscular medicine. In the United States, there is also a certification in neuromuscular medicine. This certification is open only to neurologists and physical medicine and rehabilitation specialists that have completed a fellowship in neuromuscular medicine. The neuromuscular medicine examination includes electrodiagnostic testing as part of the certification examination but also includes broader topics such as genetics, biopsy, and rehabilitation.

Patients will typically be referred to a specialist in electrodiagnostic medicine if they have numbness, tingling, pain, weakness or spasms. Common muscle and nerve disorders seen by these type of specialists include pinched nerves in the neck or back radiculopathy , carpal tunnel syndrome , and neuropathies.

More uncommon diseases include ALS , myasthenia gravis , and chronic inflammatory demyelinating polyneuropathy. Using their broader training, physicians in electrodiagnostic medicine, often perform more detailed evaluations which may include laboratory tests, CT or MRI scans, genetic evaluation, biopsy of nerve, skin, or muscle, or perform neuromuscular ultrasound.

A more complete listing of disorders and testing can be found under neuromuscular medicine. Clinical neurophysiology , is a broader field that includes EEG , intraoperative monitoring , nerve conduction studies , EMG and evoked potentials.

Electrodiagnostic medicine traces its origin back to a experiment by Luigi Galvani. Galvani depolarized frog leg muscles by using metal rods to make contact with the leg muscles. The development of the oscilloscope in significantly enhanced the ability of scientists to record signals from nerve and muscle. However, it was the needs of those with severe injuries during World War II that created the field of modern electrodiagnostic medicine.

In the early s, the first society dedicated to the development of this field, the AAEE, was founded in Chicago by a group of interested specialists in neurology and physical medicine and rehabilitation.

James Golseth was instrumental in creating this organization. From Wikipedia, the free encyclopedia. Archived from the original PDF on Retrieved Medical test : Electrodiagnosis.

Electrodiagnosis in Diseases of Nerve and Muscle: Principles and Practice

This article is only available in the PDF format. Download the PDF to view the article, as well as its associated figures and tables. This page volume written by a single author contains 26 chapters in seven parts and three appendices. Part 1 deals with basic anatomy and physiology of the neuromuscular system and basics of electrodiagnosis, including recording apparatus. The next three parts contain nerve conduction studies, tests for neuromuscular transmission, and electromyography, including single-fiber electromyography. Part 5 contains reviews of blink reflex, F wave, H-reflex, and somatosensory evoked potentials.

Intended as a handy, comprehensive reference for clinicians conducting electrodiagnostic tests, the second edition of this text includes a number of chapters entirely rewritten to reflect rapid medical and technological advancements. The text has been substantially revised and is now augmented by new citations.

Essential Physical Medicine and Rehabilitation pp Cite as. Electrodiagnostic medicine is an extension of the patient history and physical examination. These studies measure the electrical properties of neuromuscular function and can be helpful in 1 confirming a suspected diagnosis, 2 excluding other possible diagnoses, 3 identifying subclinical disease processes, 4 localizing abnormalities, 5 defining disease severity, 6 defining pathophysiology, and 7 defining disease evolution and guiding prognosis and treatment options.

Kimura has built upon his extensive experience teaching electromyography EMG around the world and has transferred his knowledge to this resource, which is intended for clinicians who perform electrodiagnostic procedures as an extension of their clinical examination. It covers noninvasive electrodiagnostic methods, particularly electromyography EMG. This resource provides a comprehensive review of most peripheral nerve and muscle diseases, including specific techniques and locations for performing each test. Access to the complete content on Oxford Medicine Online requires a subscription or purchase.

The purpose of the current article is therefore to clarify the use and limitations of electrophysiologic testing in the diagnosis and management of anesthesia-related nerve injuries. The occurrence of perioperative nerve injuries is well described. During surgery itself, direct injury or tourniquet compression to insure a bloodless field may be responsible. In rare instances, the compression is seemingly innocuous, as from a blood pressure cuff that inflates automatically at periodic intervals. In the legs, peroneal or sciatic neuropathy may lead to foot drop, which may mistakenly be attributed to a radiculopathy; an obturator or lateral femoral cutaneous neuropathy may also occur, sometimes in relation to a prolonged period in the lithotomy position.
