Eligibility Criteria
Inclusion
- INCLUSION CRITERIA:
- The Healthy volunteers will be without cardiac, pulmonary, neurological, otolaryngological, psychiatric or speech, swallowing and hearing problems as determined by medical history and examination by a physician.
- EXCLUSION CRITERIA:
- History of Rheumatic fever, mitral valve prolapse, or cardiac arrhythmias as determined by medical history, physical and EKG. A physician will auscultate for cardiac murmurs prior to any study to exclude volunteers who might be at risk for endocarditis. Subjects will have an EKG as part of the screening for participation in the study.
- Pregnancy will exclude women from participation because the study involves radiation exposure.
- None of the Healthy volunteers will have a reduction in the range of vocal fold movement during the nasoendoscopy that might suggest laryngeal paralysis or paresis, joint abnormality or neoplasm.
- Healthy Volunteers who have a cardiac demand pacemaker, dementia, exhibit non-stop vocalization, significant reflux due to use of a feeding tube, or drug toxicity will not be included for VitalStim, as these are contraindications to use of the device.
