LEMG is mainly indicated for the patients who have evidence of a movement disorder of the vocal cords. There are several types of disorders that can result in abnormal motions of the vocal cords. The purpose of LEMG is to help the physician differentiate the causes of the movement disorders and make a diagnosis. It is particularly useful in evaluating disorders affecting the nerves, the neuromuscular junctions, and the muscles of the larynx. LEMG should be considered as an extension of the physical examination. LEMG abnormalities are interpreted within the broader clinical context and are used to assist in the diagnosis and treatment of vocal cord mobility disorders.
The basic EMG principles are reviewed and important points are summarized in this article. The details of the percutaneous LEMG technique, its clinical applications and indications are introduced.
