Hyoid bone and laryngeal approximation aid airway protection (laryngeal vestibule closure) while moving toward their peak superior anterior positions during swallowing. Submental surface electrical stimulation (SES) is a therapeutic technique that targets the muscles move hyoid It unknown whether submental SES only increases swallowing but not positions, which could require faster or greater movement to achieve adequate closure.We examined effects of on hyo-laryngeal kinematics in 30 healthy adults who swallowed 50 times using an error-based learning paradigm.Submental did alter any kinematic. However, significantly changed starting position just prior swallow onset (more anterior; p = .003). On average, immediately can approximately 20% closer its point.These findings indicate agonists for might outcomes tested this study. have clinical utility by minimizing impairments related reduced range motion individuals with dysphagia.
