Electromyography (EMG)


What Is An EMG/NCS

Your doctor has referred you to the Department of Neurophysiology at CUH for a test called Electromyography (EMG) or for Nerve Conduction Studies (NCS). 

EMG is a test in which the electrical activity in muscles is analysed.  An EMG can reveal presence of muscle disorders or disorders in which the nerve supply to muscle is impaired.  Impulses are recorded by inserting a fine needle electrode into the muscle. 

Nerve conduction studies is a test which examines peripheral nerves and the way they conduct electricity.  The recording is obtained by attaching small sticker electrodes to the surface of the skin and stimulating the nerves electrically. 

No anaesthetic is required for either procedure, and there are no side effects.  You will be able to drive home.  The test lasts for 30-40 minutes.
