What is Nerve Conduction Velocity? (NCV)

Nerve conduction velocity studies are usually performed in conjunction with electromyography and can help to evaluate nerve function. They are useful in diagnosing primary nerve disease such as demyelination. During this procedure, small needle electrodes are places under the skin, over the nerve, and within the muscle innervated by the designated nerve. The nerve is stimulated and the computer records the velocity of the signal along the nerve. The external pathway of the nerve is measured and can be used with the velocity to compare with normal nerve conduction velocities. This procedure may be mildly uncomfortable for your pet during stimulation, and your pet must remain still during the procedure to eliminate unwanted voluntary action that may cause artifacts. Therefore, your pet will be under general anesthesia in order to obtain accurate results. The procedure takes about 20-30 minutes, but your pet will need some time to recover from anesthesia. You should plan on leaving your pet with us for 2-4 hours.
