Clinical neurophysiology is a medical specialty that investigates neurological diseases. This specialty employs the use of investigative techniques to record the electrical properties of muscles and neural tissue. Clinical neurophysiology consists of basic research relating to pathophysiology in addition to clinical procedures used in disease diagnosis of the central nervous system, muscular system, and peripheral nerves. This specialty, therefore, has a dual mission of searching for knowledge and also implementing that knowledge in the clinical setting.
Clinical neurophysiology mainly involves diagnosing neuromuscular diseases, epilepsy, ophthalmic disease and nerve entrapments. This specialty does not just involve laboratory tests but is an extension of a neurologic consultation. It gives a precise definition of site, degree and type of lesion to conditions that may be clinically uncertain, thereby allowing physicians to treat the condition more effectively. Neurophysiological procedures describe and measure pathophysiologic changes and functions in peripheral and central muscles as well as the nervous system.
Medical facilities that have neurosurgeons and neurologists tend to also accommodate clinical neurophysiologists. Often, these facilities are big hospitals or clinics that have the ability of employing staff that are more specialized. The major neurophysiology modalities include the following. Electroencephalography is the diagnostic test of brain waves (thalamocortical rhythms) that is conducted by hooking electrodes on the scalp to record currents. It is helpful in assessing seizures and other conditions of the central nervous system. Electromyography and nerve condition studies record electrical activity of the muscles and its passage along the limb nerves. These tests are important in assessing illnesses of the nerves, muscles, and nerve roots because it involves diagnostic tests of the peripheral nervous system. Polysomnography is a sleep study used in diagnosing disorders linked with abnormal sleep behavior. Evoked potentials are a type of test that assesses specific tracts of the peripheral and central nervous system. This may include auditory, somatosensory, or visual evoked potentials.
The American Board of Electrodiagnostic Medicine (ABEM) is a body that aims at providing patients with high-quality care in electrodiagnostic medicine. This body requires physicians to obtain specific training and demonstrate professionalism in the electrodiagnostic evaluation of disorders of the neuromuscular system. Patients can visit their website to access a database of confirmed professional doctors. Here, patients can find the best doctors.
Once you have found a good doctor, patients can visit Pharmacy Coupons to access the best drugs that can be used in electrodiagnostic evaluation. Pharmacy Coupons have great offers on these drugs and can help a patient save more. Simply search for your medication, print out the coupon and bring it to your local pharmacy to start saving money.
