Abstract

A new method of surface electromyography (EMG) is presented, for sampling the posterior crico-arytenoid, interarytenoid and crico-pharyngeal sphincter. The results obtained in normal volunteers are discussed and the indications for laryngeal electromyography (LEMG) outlined. It has the advantage of being non-invasive and safe, and can be done as an out-patient procedure with minimal discomfort to the patient, and unassociated complications. This has provided a new and fascinating field of investigation in neuromuscular disorders of the larynx. The same principles of surface EMG may also be applied to the muscles of the tongue, palate, pharynx … and surface EMG in the upper respiratory tract may become a valuable method of clinical investigation.
