Ultrasonography As Biofeedback To Increase Muscle Activation During The Mendelsohn Maneuver In Healthy Adults, Ching-Hsuan Peng

Theses and Dissertations

The purpose of this study was to examine the effect of applying real-time ultrasound as visual feedback in addition to verbal instruction/tactile feedback to facility the accuracy of learning the Mendelsohn maneuver. The Mendelsohn maneuver is one of the commonly used swallowing exercises targeting hyolaryngeal elevation and prolonging upper esophageal sphincter opening during swallow. It was hypothesized that the additional visual cueing provided by ultrasound would significantly increase sEMG activity which may be associated with increased duration and extent of hyolaryngeal elevation during the Mendelsohn maneuver as compared to the effect of verbal instruction/tactile feedback alone. A total of twenty-four …
