Unknowns about the neurophysiology of normal and disordered swallowing have stimulated exciting and important research questions. Previously, these questions were answered using clinical and animal studies. However, recent technologic advances have moved brain-imaging techniques such as functional magnetic resonance imaging (fMRI) to the forefront of(More)
This study examined age-related changes in swallowing from an integrated biomechanical and functional imaging perspective in order to more comprehensively characterize changes in swallowing associated with age. We examined swallowing-related fMRI brain activity and videoflouroscopic biomechanics of three bolus types (saliva, water and barium) in 12 young(More)
Normal esophageal bolus transport in asymptomatic healthy older adults has not been well defined, potentially leading to ambiguity in differentiating esophageal swallowing patterns of dysphagic and healthy individuals. This pilot study of 24 young (45-64 years) and old (65+years) men and women was designed to assess radiographic esophageal bolus movement(More)
Swallowing disorders (dysphagia) are associated with malnutrition, aspiration pneumonia, and mortality in older adults. Strengthening interventions have shown promising results, but the effectiveness of treating dysphagia in older adults remains to be established. The Swallow STRengthening OropharyNGeal (Swallow STRONG) Program is a multidisciplinary(More)
OBJECTIVES To (1) compare 2 distinct isometric lingual press tasks, fine sensorimotor versus gross sensorimotor, at multiple sensor locations in relation to age and sex; and (2) provide a normative data set using a lingual-strengthening device. DESIGN Cohort study. SETTING University. PARTICIPANTS Healthy men and women (N=71; age range, 21-82y)(More)
The transformation of the upper aerodigestive tract--oral cavity, pharynx, and larynx--serves the functions of eating, speaking, and breathing during sleeping and waking hours. These life-sustaining functions may be produced by a central neural sensorimotor system that shares certain neuroanatomic networks while maintaining separate neural functional(More)
