​An ENMG study is used to clarify damages and functional disturbances in the peripheral nervous system and muscles, for example nerve entrapment, nerve root damages, polyneuropathy and muscle diseases. Pain states, symptoms of numbness, decreased sensation and muscle weakness are common reasons for performing the examination. The study measures the conduction velocity of nerves and the electric function of muscles.

An ENMG study is performed to the extent required by the patient’s symptoms and defined in the physician’s referral. When examining the conduction velocity of nerves, adhesive measuring electrodes are attached to the skin – on the finger, for example – and then the examined nerve is administered small electric pulses in the wrist, for instance. The function of muscles is examined by pricking the examined muscle with a very thin needle electrode. Based on the measurement result, a report on the examination is issued.

You should inform the nursing staff of any possible Marevan medication, blood-borne diseases or a cardiac pacemaker, but otherwise the study does not require any special preliminary preparations.

The duration of the examination is approximately 30 minutes to one hour. Excluding occasional, temporary bruises, the examination does not have any after-effects.
