<P> A nerve conduction study (NCS) is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body . These tests may be performed by medical specialists such as clinical neurophysiologists, chiropractors, physiatrists (physical medicine and rehabilitation physicians), and neurologists who subspecialize in electrodiagnostic medicine . In the United States, neurologists and physiatrists receive training in electrodiagnostic medicine (performing needle electromyography and NCSs) as part of residency training and in some cases acquire additional expertise during a fellowship in clinical neurophysiology, electrodiagnostic medicine, or neuromuscular medicine . Outside the US, clinical neurophysiologists learn needle EMG and NCS testing . </P> <P> Nerve conduction velocity (NCV) is a common measurement made during this test . The term NCV often is used to mean the actual test, but this may be misleading, since velocity is only one measurement in the test suite . </P>

Is an emg the same as a nerve conduction test
