Analysis of cervical plethysmography data in diagnosis of chronic
cerebro-spinal veinous insufficiency
PROFESSOR SIMON J. SHEPHERD, PHD
FELLOW OF THE ROYAL SOCIETY OF MEDICINE
The presentation describes the initial mathematical and physical analysis of patient and
control data from the new cervical plethysmography diagnostic technique, introduced
by Professor Zamboni, in the diagnosis of CCSVI.
We show that the data produced is consistent with previous recent work which showed
that the hydrodynamics of the brain is very closely approximated by a second-order
We show that a classical two-parameter characterisation of the second-order response
curves to the Heaviside step function could be a powerful classification technique for
diagnosis of CCSVI.
