Electromyography (EMG), <br /> Nerve Conduction Study (NCS)

During an EMG, muscle waves are measured, similar to an EKG. Using this technique, normal muscle function can be determined from abnormal. Typical symptoms include muscle inflammation, damage to the nerves responsible for muscle movement, damage to the connection between nerves and muscles. NCS examines motor function and sensitive nerves.

During NCS procedures, metal plates are glued to the intact skin over the muscle area. Short, weak electric waves prompt muscle reactions. These waves travel through the healthy skin to the nerves.

In general, the EMG is done with a thin, sterilized needle under the skin, into the muscle. once there, it receives the low muscles waves and transmits them to the machine, which gives them a visual medium to be analyzed.
