Purpose. We evaluated the intra- and interrater agreement and test-retest reliability of analyst derivation of swallow function variables based on repeated high resolution manometry with impedance measurements. Methods. Five subjects swallowed 10 × 10 mL saline on two occasions one week apart producing a database of 100 swallows. Swallows were(More)
Diagnostic assessment of swallowing in routine clinical practice relies heavily on the long-standing techniques of videofluoroscopic swallowing study (VFSS) and videoendoscopic evaluation of swallowing (VEES). These complementary and sophisticated techniques provide a real-time visualization of biomechanical movements of the structures involved in(More)
OBJECTIVE Clinical data are submitted as documentation of a pathophysiologic feature of dysphagia termed pharyngeal mis-sequencing and to encourage clinicians and researchers to adopt more critical approaches to diagnosis and treatment planning. BACKGROUND Recent clinical experience has identified a cohort of patients who present with an atypical(More)
OBJECTIVE (1) To determine potential relationships between speech intelligibility, acceptability, and self-reported quality of life (QOL) after total laryngectomy and (2) to determine whether relationships are stronger when QOL is measured by a head and neck cancer-specific or discipline-specific QOL scale. STUDY DESIGN Cross-sectional. SETTING(More)
OBJECTIVE The purpose of this study was to determine how a new self-report outcome measure of communicative participation, the Communicative Participation Item Bank (CPIB), related to disease- and discipline-specific quality of life (QOL) outcomes in a head and neck cancer (HNC) population. METHODS One hundred ninety-five individuals treated for HNC(More)
INTRODUCTION Previous research has documented that pressure and duration of brainstem-generated pharyngeal swallowing can be cortically modulated. But there is a commonly held belief that the sequence of pharyngeal pressure remains constant. However, Huckabee et al. [19] reported a patient cohort who demonstrated reduced latency of peak pressure in the(More)
BACKGROUND A substantial pressure drift in high-resolution manometry (HRM) has been reported; however, fundamental questions remain regarding the origin and management of this drift. The aim of this study was to provide critical in-depth analyses of ManoScan(™) HRM drift in vitro and in vivo. METHODS A total of sixteen 15-min studies and twelve 5-h(More)
