Extraction of average neck flexion angle during swallowing in neutral and chin-tuck positions
BACKGROUND A common but debated technique in the management of swallowing difficulties is the chin tuck swallow, where the neck is flexed forward prior to swallowing. Natural variations in chin tuck angles across individuals may contribute to the differential effectiveness of the technique. METHODOLOGY To facilitate the study of chin tuck angle variations, we present a template tracking algor...
متن کاملEffectiveness of Chin-tuck Maneuver to Facilitate Swallowing in Neurologic Dysphagia.
Introduction The chin-tuck maneuver is the most frequently employed postural maneuver in the treatment of neurogenic oropharyngeal dysphagia caused by encephalic vascular strokes and degenerative diseases. Objective The purpose of this study was to investigate the effectiveness of this maneuver in patients with neurogenic dysphagia and factors that could interfere in it. Methods In this retrosp...
متن کاملThe Sequence of Swallowing Events During the Chin-Down Posture.
PURPOSE This study investigated the effect of the chin-down posture on the sequence of swallowing events in healthy adults. METHOD Sixteen healthy participants performed 45 5-ml thin liquid swallows during videofluoroscopy: 5 neutral head position, 30 chin-down posture, and then 10 neutral head position. Eight swallowing events were measured: the time of hyoid burst, bolus head in the pharynx...
متن کاملMechanisms of airway protection during chin-down swallowing.
PURPOSE This study examined the effects of chin-down swallowing on laryngeal vestibule closure. It also investigated the technique's rehabilitative impact, by assessing the stability of effects across multiple trials and aftereffects in neutral swallows on cessation of the technique. METHOD Duration of laryngeal vestibule closure (dLVC) was measured with videofluoroscopy in 16 healthy partici...
متن کاملEffect of three different chin-down maneuvers on swallowing pressure in healthy young adults.
OBJECTIVES/HYPOTHESIS To determine the effects of three different chin-down maneuvers on swallowing pressure (SP) in healthy young adults using high-resolution manometry (HRM). STUDY DESIGN Repeated measures with subjects serving as their own controls. METHODS Twenty-six healthy subjects (average age 26.4 [range 21-35] years) swallowed 5 mL of cold water to examine the maximum swallowing pr...
