OBJECTIVE To identify the differences in the movement of the hyoid bone and the vocal cord with and without electrical stimulation in normal subjects. METHODS Two-dimensional motion analysis using a videofluoroscopic swallowing study with and without electrical stimulation was performed. Surface electrical stimulation was applied during swallowing using(More)
weakening model, in which friction was assumed to decrease as slip on the fault increased. The key model parameter was the slip-weakening distance (the amount of slip required to reduce friction at high speeds). This phenomenological model avoided the difficult question of the origin of friction. Mechanical studies of rocks in the late 1970s provided the(More)
Effortful swallowing (EFS) is a common compensatory swallowing manoeuver for dysphagia patients. We investigated the influence of EFS on temporal and spatial characteristics of the movements of the hyoid bone, larynx and epiglottis in healthy subjects. A total of 41 volunteers swallowed 10 mL of diluted barium solution using two swallowing strategies: usual(More)
