Safety and efficacy of peripheral nerve stimulation of the occipital nerves for the management of chronic migraine: Results from a randomized, multicenter, double-blinded, controlled study
This study followed 157 participants who suffered from a headache on average 21 days per month. After 12 weeks, the patients receiving PNS therapy reported that their headaches had reduced to an average of 6 or fewer per month. In addition, the participants reported a 43% reduction in pain as noted by the MIDAS questionnaire, and a 42% average improvement in pain relief. More than half of the participants ranked their relief as good or excellent.
