Abstract

DESCRIPTION (provided by applicant): PROJECT SUMMARY/ABSTRACT Swallowing impairments (dysphagia) represent the highest functional morbidity in veteran patients treated for oropharyngeal cancers with either surgical approaches followed by radiation or with more recent organ-preservation protocols. The nature of the impairments is often resistive to treatment and results in life-long health consequences and high cost burden on the VA health system. Recent preliminary data have linked alterations in the otherwise highly stable respiratory-swallowing phase pattern relationships to the swallowing impairment and penetration/aspiration and in this patient group. The immediate goal of this clinical trial is to test the effect of a novel respiratory-swallow intervention on swallowing impairment and penetration/aspiration in a cohort of chronically dysphagic veterans following treatment for oropharyngeal cancer. Patients presenting with a non-optimal respiratory-swallow phase pattern during liquid swallows and measurable swallowing impairment will learn an optimal physiologic pattern that facilitates both airway protective and mechanical advantages during swallowing. The broad goal of this research is to develop ideal respiratory- swallowing phase training methods and regimens that alone or combined with traditional swallowing treatments improve swallowing function in the acute phases of recovery and improve long term patient outcome. Our intention is to use these preliminary data to motivate a larger clinical trial to compare the effect of respiratory-swallow phase training with other evidenced based methods of swallowing treatment and expand the approach to other patient groups that have indications of respiratory- swallow phase impairments (e.g. pulmonary disease and stroke) contributing to impaired swallowing function.
