Autonomic Technologies, Inc.
ClinicalTrials.gov Identifier:
NCT01359631
First received: May 23, 2011
Last updated: May 13, 2012
Last verified: May 2012
  Purpose

Hypothesis:

Stimulation of the SPG at high frequencies (50-200Hz) is believed to cause a physiological parasympathetic block which decreases VMCA oxyHb concentration and cephalic vessel diameter.

Stimulation of the SPG at low frequencies (1-60 Hz)is believed to cause a physiological parasympathetic upregulation which increases VMCA, oxyHb concentration and cephalic vessel diameter.


Condition
Chronic Cluster Headache

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Cephalic Vascular Recording Upon SPG Stimulation in CH Patients - Amendment to the Pathway CH-1 Trial
