Advances in the measurement of swallowing physiologic parameters have been clinician-driven, as has the development of intervention techniques to modify swallowing pathophysiology. However, a critical element to determining the success of such efforts will be established by the patients themselves. We conceptualized, developed, and validated the SWAL-QOL, a(More)
OBJECTIVE To examine the effects of lingual exercise on swallowing recovery poststroke. DESIGN Prospective cohort intervention study, with 4- and 8-week follow-ups. SETTING Dysphagia clinic, tertiary care center. PARTICIPANTS Ten stroke patients (n=6, acute: < or =3mo poststroke; n=4, chronic: >3mo poststroke), age 51 to 90 years (mean, 69.7y). (More)
The risk for disordered oropharyngeal swallowing (dysphagia) increases with age. Loss of swallowing function can have devastating health implications, including dehydration, malnutrition, pneumonia, and reduced quality of life. Age-related changes increase risk for dysphagia. First, natural, healthy aging takes its toll on head and neck anatomy and(More)
OBJECTIVES To determine the effects of an 8-week progressive lingual resistance exercise program on swallowing in older individuals, the most "at risk" group for dysphagia. DESIGN Prospective cohort intervention study. SETTING Subjects were recruited from the community at large. PARTICIPANTS Ten healthy men and women aged 70 to 89. INTERVENTION Each(More)
PURPOSE This review presents the state of swallowing rehabilitation science as it relates to evidence for neural plastic changes in the brain. The case is made for essential collaboration between clinical and basic scientists to expand the positive influences of dysphagia rehabilitation in synergy with growth in technology and knowledge. The intent is to(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)
OBJECTIVES To determine whether classic muscle function tests and jumping mechanography (JM) are related to tongue strength. DESIGN Cross-sectional. SETTING Community. PARTICIPANTS Ninety-seven community-dwelling individuals aged 70 and older (49 female, 48 male, mean age 80.7, range 70-95) with and without identified sarcopenia. MEASUREMENTS(More)
Swallowing is a complex neurogenic sensorimotor process involving all levels of the neuraxis and a vast number of muscles and anatomic structures. Disruption of any of these anatomic or functional components can lead to swallowing disorders (also known as dysphagia). Understanding the neural pathways that govern swallowing is necessary in diagnosing and(More)
The aim of this study was to quantify the association between a dysphagia-specific quality of life (SWAL-QOL) and quality of care (SWAL-CARE) questionnaire and four measures of bolus flow. Three hundred eighty-six people with oropharyngeal dysphagia completed a videofluoroscopic examination of their swallowing structure and physiology. They also completed(More)
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)
