| Nerve Conduction Velocity is a diagnostic exam that evaluates the function of the motor and sensory nerves throughout the body. This test is often performed to evaluate patients with numbness, tingling and/or weakness in the arms and legs. |
|
| This test is usually done with surface patch electrodes (they are similar to those used for an electro diagram), that are placed on the skin over the nerve at various locations. One electrode stimulates the nerve with a very mild electrical impulse. The resulting electrical activity is recorded by the other electrodes. The distance between electrodes and the time it takes for electrical impulses to travel between electrodes are used to calculate the speed of impulse transmission 9nerve conduction electrodes are used too calculate the speed of impulse transmission (NCV). |
