Single fiber electromyography with a standard monopolar electrode

A technique of obtaining qualitative single fiber electromyography information with standard monopolar electrodes is described. The technique requires an electromyograph equipped with a trigger and delay line. Single fiber electromyography is an effective tool in dealing with disorders that affect neuromuscular transmission and for observing the recovery of nerve injuries. Since most problems encountered in clinical practice deal with the diagnosis and follow-up of radiculopathies and peripheral nerve compromise, the use of single fiber electromyography in these conditions is of great clinical importance.
