Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    TENS device FDA-approved for migraine prevention

    CEFALY_2_HR_sans les mainsIt’s the first device approved to prevent migraine headaches, and the first transcutaneous electrical nerve stimulation (TENS) device specifically authorized for use prior to the onset of pain.

    Here’s what we know about Cefaly.

    The device

    • Cefaly is a small, portable, battery-powered, prescription device.
    • Resembles a plastic headband worn across the forehead and atop the ears
    • Attached to the center of the forehead, above the eyes, using a self-adhesive electrode
    • Applies an electric current to the skin and underlying body tissues to stimulate branches of the trigeminal nerve, which is associated with migraine headaches
    • The user may feel a tingling or massaging sensation where the electrode is applied.

    Now, the details.

    • A 67-person study in Belgium compared Celaly to placebo.

    And, the results.

    • Significantly fewer days with migraines per month vs. a placebo device
    • Less use of migraine attack medication vs. a placebo device
    • Cefaly did not completely prevent migraines and did not reduce the intensity of migraines that did occur.
    • Most commonly reported complaints
      • Not wanting to continue using the device because of how it felt
      • Sleepiness during the treatment session
      • Headache after the treatment session

    The bottom line?

    Cefaly is indicated for patients at least 18 years of age and should only be used once per day for 20 minutes.

    In a patient satisfaction study of 2,313 Cefaly users in France and Belgium, about 53% were satisfied with Cefaly treatment and willing to buy the device for continued use.
