Nerve Conduction Study in Dubai
This is a routine test performed in our clinic at www.bestneurologistdubai , as an outpatient procedure. The EMG (electromyography) records the electrical impulses that your muscles produce. The Nerve Conduction test measures the speed at which impulses travel along a nerve. These tests help us to work out how well your nerves and muscles are functioning. They are often referred to collectively as an EMG test and may incorporate one or both of the above techniques.What does EMG stand for?
Electro-The electrical impulses that are being measured.

How do EMG/Nerve Conduction studies work?
The Nerve Conduction Study records how fast nerves send messages to the brain and back. In the test, we stimulate the nerves using electrodes placed on the surface of a person’s skin.We can then record how fast the impulse travels to another point, where it is recorded using a surface electrode placed on the skin (on rare occasions a fine needle electrode in the muscle may have to be used to take a recording). This tells us how fastthe nerve is working. EMG studies the electrical activity of the muscles. This is usually recorded using a small needle electrode inserted through the skin into the muscle, which produces a short pinprick sensation. Once in place the activity in the muscle can be observed at rest and then whilst being used.
Clinical Applications of Nerve Conduction Study in Dubai
Nerve conduction studies provide the most sensitive and accurate account of peripheral neuropathophysiology. Though nerve conduction studies should never be performed in lieu of a clinical examination, the electrodiagnostic evaluation provides an optimal adjuvant to the clinical examination. Indications for nerve conduction studies are many, including evaluation of the nature of the pathophysiology, quantification of the severity of involvement, detection of the level of a neurologic deficit, and determining prognosis. Among other indications, limitations of the study should also be acknowledged, such as its confined evaluation of large myelinated peripheral nerve fibers. It should be understood that nerve conduction studies are conventionally performed with EMG studies, typically performed consecutively in order to provide a comprehensive evaluation of suspected neuromuscular impairment. It is imperative to emphasize that utilization of nerve conduction findings is limited and potentially misdirected without a thorough knowledge of peripheral neuropathophysiology and related conditions. Parameters by which the studies are evaluated are outlined in detail within this article and discussed in terms of clinical and neurophysiological significance. Reference tables are provided on the normal values of individual peripheral nerves, as established by various investigators. Nerve conduction findings and their clinical significance relative to various pathophysiological conditions are reviewed. Radiculopathies, lesions of the lumbosacral plexus, polyneuropathies, as well as mononeuropathy multiplex and simplex, are also discussed relative to their various etiologies, and respective forms of pathogenesis. Finally, nerve conduction studies may be effectively used to select the most beneficial therapy. Appropriate consultative referral is addressed with regard to primary pathologic conditions requiring neurosurgical, neurologic, rheumatologic, and immunologic care, among other disciplines relative to the underlying pathologic process. Local therapy may invariably be gauged in terms of various modes of medical, orthopedic, and surgical intervention, depending on the degree, nature, and distribution of involvement of the neuropathy, as ultimately determined by the nerve conduction studies. In conclusion, nerve conduction studies provide a reliable index of measurement in the diagnosis, treatment, and prognosis of the patient.
The conditions that usually require Nerve conduction study for diagnosis and deciding the treatment:
- Peripheral nerve entrapment syndromes
- Hereditary, metabolic, or degenerativepolyneuropathy
- Plexopathy (acquired disorder in tissue along nerves that causes motor and sensory dysfunction)
- Neuromuscular junction disorders
- Myopathies o
- Motor neuron disease
- Spine disorder withnerve root impingement symptoms
- Cervical, thoracic, and/or lumbosacral radiculopathy
- Guidance for botulinum toxin injection for spasmodic dysphonia or segmental dystonia when it is difficult to isolate affected muscles
- Traumatic nerve lesions
