Nerve Conduction Studies (NCS) and Electromyography (EMG)
Electromyography (EMG) is a diagnostic procedure that measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is done to find problems that damage muscle tissue, nerves, or the spots where nerves and muscles join and is used to help detect neuromuscular abnormalities.
A related procedure that may be performed is Nerve Conduction Study (NCS). NCS is a measurement of the amount and speed of conduction of an electrical impulse through a nerve. NCS can determine nerve damage and destruction, and is often performed at the same time as EMG. Both procedures help to detect the presence, location, and extent of diseases that damage the nerves and muscles.
Nerve conduction studies are used mainly for evaluation of paraesthesia’s (numbness, tingling, burning) and/or weakness of the arms and legs. A physical exam and thorough history also help to direct the investigation.
Some of the common disorders that can be diagnosed by nerve conduction studies are:
Carpal tunnel syndrome
Cubital Tunnel Syndrome
Tarsal Tunnel Syndrome
