NERVE CONDUCTION STUDIES (NCS OR NCV):

Many of the nerves, especially of upper and lower limbs, are tested by stimulating them at multiple sites with a small harmless current mimicking the natural impulse, and recording from a muscle or over the skin by sticking ECG type electrodes. Any compression or damage to the nerve along its path is detected and its severity known. A tingling current like sensation is felt, which is absolutely harmless, and does not interfere with even pacemakers, and is easily tolerated by all age groups.

 

ELECTROMYOGRAPHY (EMG):
