Regular TENS Unit Instead of Cefaly?
“Can I use a regular TENS unit instead of Cefaly?” I’ve been asked this questions so many times that I know others are curious and haven’t asked. I can’t give you a direct yes or no, but here’s what I’ve seen headache specialists say about it.
Writing for the American Headache Society, headache specialist Brian Plato, D.O, says, “It should be noted that “regular” TENS units should not be used in place of the Cefaly.” He does not explain why.
Headache specialist Alexander Mauskop, M.D., said in a comment on my Migraine.com post about Cefaly, “My patients haven’t had much success with Cefaly. To save them money, I suggest that they try a regular TENS unit, which can costs as little as $50. It is not as cool-looking or convenient, but it offers more options in adjusting the current, frequency of stimulation and duration.”
Dr. Mauskop wrote on his blog that he was unsure whether Cefaly has an advantage over a regular TENS unit. He speculates that Cefaly could be better because of its convenience and that the current “may have specific frequency, strength and wave shape, which provides better relief. However, an electrical engineer could easily hook up the Cefaly unit to a monitor and figure out and publicize these settings.” (To my knowledge, no one has done this.)
Many patients point out in forums that their doctors and the instructions with their TENS units say not to use them on your head. One said that a regular TENS unit may be too strong for the forehead.
That’s all I can tell you. I cannot give a direct recommendation either way. Even if I could, I don’t have enough information to form a solid opinion. My best advice is to talk to your doctor about it.
