Information for Nerve Conduction Studies (NCS)

Nerve and muscle disorders cause the muscles to react in abnormal ways. Measuring the electrical activity in muscles and nerves can help find diseases that damage muscle tissue (such as myopathy or muscular dystrophy) or nerves (such as peripheral neuropathies). EMG and nerve conduction studies are often done together to give more complete information.

Nerve Conduction Studies (NCS)

Nerve conduction studies measure how well and how fast the nerves can send electrical signals. Nerves control the muscles in the body by electrical signals, and these impulses make the muscles react in specific ways. NCS can aid in locating damage to the nervous system, which includes all the nerves that lead away from the brain and spinal cord and the smaller nerves that branch out from those nerves as well as junctions between the nerves and muscles. NCS study is performed by placing the electrode on the affected arm or leg. Then a small amount of current is applied to measure the electric signals. You may feel a little shock. NCS study is performed by a doctor or trained technologist.
