Physiological Changes With SPG Stimulation in Migraine Patients

July 31, 2022 updated by: Song Guo, Danish Headache Center

Physiological Changes Induced With SPG Stimulation in Migraine Patients - Amendment to the Pathway M-1 Trial

Hypothesis:

Stimulation of the SPG at low frequencies (20 Hz)is believed to cause a physiological parasympathetic upregulation which increases VMCA, concentration and cephalic vessel diameter.
