Zamboni paper with the 5 Doppler tests (published late last year), has the tests performed specifically in a sitting and/or laying down position.

Where can I get the protocols for sitting and prone dopplers? Does Zamboni's paper from last year have them? If so, please post or send. Thank you.

You can find them on the research thread. http://www.thisisms.com/ftopict-7098.html

This paper is the first doppler studies of 89 MS patients and 60 controls.
All MSers had at least 2 venous abnormalities; 100% concordance. This first study was not blinded, it was to discover how MS patients might be consistently assessed with doppler to evaluate venous drainage. This work resulted in a doppler protocol as described in "Doppler haemodynamics of cerebral venous return", below.

This paper describes how to do the tests and suggests parameters for normal findings. Copy this page for the sonographer if needed.
