Nerve Conduction Velocity (Overview)

Nerve conduction velocity is the speed with which a nerve transmits it's signal on EMG testing. It can be slowed by damage by compression, or by medical conditions such as neuropathy of various causes.

Is conduction velocity the same is nerve conduction velocity?

Is conduction velocity the same is nerve conduction velocity?

Yes: Both are ways of representing the speed at which signals travel down the peripheral nerves. Conduction velocity is decreased in diseases that damage the nerve insulation, either focally (as in carpal tunnel syndrome) or globally (as in guillan barre). ...Read more

What is a nerve conduction velocity (NCV) test?

What is a nerve conduction velocity (NCV) test?

Part of EMG: Nerve function can be tested using electromyography, and the NCV test applies an electrical shock over the nerve to ascertain if normal velocity and voltage is present. Patterns of nerve abnormality can diagnose different diseases. ...Read more

What happens during a nerve conduction study?

EMG: This test evaluates nerve and muscle fnctn to determine if it is normal. Testing of nerves involves applying an electrical shock over a nerve and recording the response over a muscle connected to the nerve. Results can be compared to normal values for voltage and velocity, and both motor and sensory function can be included. The muscle can directly be tested using a small needle. Very safe! ...Read more

How to interpret nerve conduction study report?

How to interpret nerve conduction study report?

Very Hard: I would suggest if you can't figure it out, you speak with the doctor that either ordered it or the doctor that performed it. Ask them to speak in lay terms with you. Otherwise unless you have prior medical background it will be another language for sure. ...Read more

Can nerve conduction tests be wrong?

No: Though there are limitations on what a nerve conductions test can show. If it shows something (and is done by a knowledgeable physician), it is definitely there. It may not be sensitive enough to pick up subtle changes. Not every nerve condition is detectable by this test. If done too soon after an injury (less than 3 weeks), may not show up. If symptoms are worsening, it is worth retesting. ...Read more

Does a nerve conduction study and an emg hurt?

Does a nerve conduction study and an emg hurt?

Maybe uncomfortable: Most patient's tell me it was not as painful as anticipated. The ncs involves electrical stimulation of the nerves, the EMG involves inserting a very small needle into several mucles. I think most patients describe the test as uncomfortable not painful. ...Read more

Difference between nerve conduction study and emg?

Difference between nerve conduction study and emg?

See below: The EMG portion uses a small needle to directly examine muscle function, and the nerve conduction part uses electrical shocks to measure nerve function. Together the study gives a good idea of the nature of the pathology and location, but can also assess the prognosis and character, and gives often guidance towards an eventual diagnosis. ...Read more

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
