The electric impulses that control our muscles usually travel at a certain speed though the nerve pathways in healthy people. Through the measuring of the nerve conduction velocity, we can see whether the speed of transmission is reduced due to an illness or, in the worst case, whether the nerve transmission is completely blocked.
The test is quite simple: Electrodes are stuck onto the skin above the nerves, which are to be examined. Then the nerve is stimulated by short, artificial electric impulses. Using a second electrode at the end, we measure the time necessary for the transmission. And we can also measure how long your body needs to react to such impulses. During the examination, you will only feel the short impulses through the electrodes.
This test is also known as nerve conduction study (NCS)
