[DYSPHAGIA] Liquid Viscosities in VFSS

[drjeff6@juno.com (Jeffrey Lewis)]

There is a commercially available device that measures liquid viscosity.  I
saw it at the exhibit hall at ASHA.  It was a kinda expensive device (a
grand or so).  Regrettably, I don't recall the manufacturer.  Possibly you
could find it on the ASHA website which, as I recall, has a link to stuff
about last year's convention.

The topic of liquid viscosity measurement has come up many, many times over
the past couple of years at our hospitals. I've
thought about waiting until a hand-held viscometer is on the market (or are
they out now?) because with this, we'd be able
to measure any liquid. Others have brought up using the pre measured drink
boxes mixed with Barium but my thought is that
even they are not always consistent and in addition, the barium would also
change the viscosity so it still would not be
stable. Someone also mentioned pre-thickened barium. Does any one use this?
Is it costly? Where do you get it?

How are others measuring thickness? I am currently using an unscientific
"eyeball" method as I've found nothing I trust
more... Ideas?

Thanks, Jo Ellen
