Cephalic Vascular Recording Upon SPG Stimulation

Completed

• Conditions: Chronic Cluster Headache

• Registration Number: NCT01359631
• Lead Sponsor: Autonomic Technologies, Inc.

Brief Summary

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.
