Hyoid movement during swallowing in older patients with dysphagia.
OBJECTIVES To describe the timing, coordination, and extent of hyoid movement in a population of older adults with dysphagia and to evaluate the effect of hyoid movement on upper esophageal sphincter opening. DESIGN A retrospective review of dynamic swallow studies performed between January 1996 and December 1999 was done. SUBJECTS Patients included in the study were 65 years or older, with...
متن کاملRelationship between Class III malocclusion and hyoid bone displacement during swallowing: a cine-magnetic resonance imaging study
OBJECTIVE The displacement of the hyoid bone (HB) is a critical biomechanical component of the swallowing function. The aim of this study was to evaluate the swallowing-induced vertical and horizontal displacements of the HB in subjects with 2 different magnitudes of skeletal Class III malocclusion, by means of real-time, balanced turbo-field-echo (B-TFE) cine-magnetic resonance imaging. METH...
متن کاملHyoid movement and laryngeal penetration during sequential swallowing.
This study examined hyoid movement during sequential swallowing and evaluated the relationship among trajectory patterns, swallowing types based on laryngeal movement and laryngeal penetration. Twelve healthy adults underwent videofluorography during sequential swallowing. Each swallow was classified into two types: opened laryngeal vestibule after swallow (i-Segmental type) and closed laryngea...
متن کاملDynamic swallowing study for globus patients
Objective To examine whether pharyngeal swallowing function is impaired in globus patients with swallowing difficulty by dynamic swallowing study. Methods Dynamic swallowing studies were performed on 80 normal adult volunteers and 33 globus patients with swallowing difficulty. Objective parameters such as maximum displacement of the hyoid bone, pharyngeal transit time, pharyngeal constriction...
متن کاملDisplacement structure and maximum entropy
The study of matrices with a displacement structure is mainly concerned with recursions for the so-called generator matrices. The recursion usually involves free parameters, which can be chosen in several ways so as to simplify the resulting algorithm. In this correspondence we present a choice for the parameters that is motivated by a maximumentropy formulation. This choice further motivates t...
