Electrodiagnosis

emg 1

Electrodiagnosis is a method of obtaining information about diseases by passively recording the electrical activity of body parts.

Two tests are commonly used:

•             Electromyography (EMG):  is a technique for evaluating and recording the electrical activity produced by skeletal muscles

•             Nerve conduction studies (NCS): commonly used to evaluate the function of electrical conduction, of the sensory nerves of the human body

Other tests are Julie test and V.E.P.

Electrodiagnosis is the field of study that, by employing the science of electrophysiology, uses electrical technology to study human neurophysiology. Neurodiagnostics (NDS), electromyography (EMG), and evoked potentials (EPs) are aspects of electrodiagnosis.

Information needed to answer any questions regarding nerve injury, muscle injury, muscle disease, localization, and prognosis can be obtained through electrodiagnostic testing. This information should help to focus treatment on the exact site of injury.

Interestingly, the information provided by electrodiagnosis is functional and not static, telling the practitioner how the nerve and muscle are functioning.
