* NOTE - Procedure Change:
inclusion of two consistencies so as to better generalize the data has been
instituted. Rather than 3 simple
water swallows, the subject will be asked to swallow: 3 presentations 10 ml of
water, 3 presentations 10 ml of honey consistency liquids, and 3 presentations
10 ml of puree consistency (apple sauce). The
multiple consistency trials will proceed to an n of 500 is obtained. The
3 presentations 10 water only will continue at least until the initial n
of 1,000 subjects is reached.
The target n for the initial pool
will be 1,000 heterogeneous individuals between 18 and 100 years of age.
Approximately evenly distributed male/female and age grouped roughly:
to 29 125
30 to 39 125
40 to 49 125
50 to 59 125
60 to 69 125
70 to 79 125
80 to 89 125
90 plus 125

proposed research project will entail the gathering of sufficient non-dysphagic
(normal) individuals so as to initiate a database against which persons with
swallowing disorders may be measured. This
database will include such data and be arranged so as to take into consideration
the various factors and history that may lead to dysphagia subsequent to
neurological insult. Participating
individuals will be given the Bedside Assessment of Swallowing Safety©
including the 10-milliliter thin liquid (barium) test swallow.
A current family and personal health history will be obtained for later
database inquiries. The test
swallow will be analyzed and measured and these measurements included in the
database. The actual swallow will
be archived for further additional research.
swallow will be captured using a McKaig Auscultation Collar© with
a specially prepared radiolucent stethoscope head and available fluoroscopic
table (to be later designated) coupled to a high quality S-VHS recorder (to be
later designated) and subsequently digitized using a Studio 10 plus® video
digitized these images will be analyzed using the Sound Forge XP® These files
will be matched with the individual’s initials and date of birth, and upon
entry to database assigned a random number and the original record destroyed.
Medical history will be entered using the standard ICD9 coding.

heterogeneous group of patients who would be tested with VFSS as part of their
general healthcare. This population
will be predominantly geriatric in makeup as the population with dysphagia tends
to fall into this group as dysphagia most commonly occurring in progressive
neurological disorders and cerebral vascular accidents which are most common in
the population over 60 years of age.
