Can Remote Electrical Neuromodulation Help Acute Migraine?


Remote Electrical Neuromodulation (REN) may provide relief of migraine pain and most bothersome symptoms compared to placebo, a new study found. The efficacy and safety of a REN device for acute treatment of migraine was assessed. The randomized, double-blind, multicenter study was conducted at 7 sites in the United States and 5 sites in Israel. The study included 252 adults meeting the International Classification of Headache Disorders criteria for migraine with 2 to 8 migraine headaches per month, and the patients were randomized 1:1 to active or sham stimulation. Among the findings:

  • Active stimulation was more effective than sham stimulation in achieving pain relief, pain-free, and MBS relief at 2 hours post-treatment.
  • The pain relief of the active treatment was sustained 48 hours post-treatment.
  • Incidence of device-related adverse events was low and similar between treatment groups.
