Medtronic has revealed positive results from a trial to test occipital nerve stimulation for the treatment of chronic migraines.
The randomised and blinded trial was conducted across nine centres and involved 66 patients with chronic migraines, who were evaluated for a period of three months.
The patients were randomised into three groups; the first received adjustable simulation, the second received neurostimulation as a part of a control group, and the third only received medical management.
Among the 28 patients who received adjustable nerve simulation, 39% (11) experienced a 50% decrease in the intensity of the headaches.
They also experienced a 27% decrease in the number of headaches per month during the third month.
The study has been published in Cephalalgia.
