Randomized Controlled Trial
Occipital nerve stimulation for chronic migraine: a randomized trial on subthreshold stimulation.
Occipital nerve stimulation (ONS) may provide pain relief in migraine patients. In this double-blinded trial we investigated the significance of paresthesia and possible placebo effects. ⋯ Paresthesia is not required to achieve pain reduction but suprathreshold stimulation yields better results, underlining the significance of stimulation parameter customization.
