Abstract
In this paper, we introduce a new electrophysiological and mechanical method used tomeasure laryngeal movements and related submental (SM) muscle and crycopharyngeusmuscle (CP) of the upper eosaphageal sphincter EMG activity during swallowing. Thismethod was applied to sixty normal subjects who do not ever complain of dysphagia; andphysiological parameters related to swallowing were obtained. It is proposed that this method is cheap, practical, repeatable and available in every EMG laboratory, and it be used in the study of physiology of deglutition as well as in objective evaluation of neurogenic dysphagia .
