I’ve been asked so many times about Livia in the past month that I figured it’s time for me to just post on it.
The makers of the device claim it is an “off switch for period pain” and that it is a “new device.”
What Livia appears to be is a TENS unit, which is a transcutaneous electrical nerve stimulation device. This is not new technology and it isn’t new for period pain. I have been prescribing them for well over 10 years. I probably prescribe 1-2 a week, sometimes more.
TENS is in fact so well entrenched for period pain that there is even a Cochrane review that supports its use (with high frequency settings). The review was first written in 2002, so yeah, like I said not exactly new.
There is nothing listed in the site for Livia nor anything the CEO has said that suggests the device is anything but a TENS. In fact, he even uses the term “gate theory,” which is of course one possible mechanism of action of a TENS.
What’s the gate theory? Think of the connections in your brain as gates, with both vibration and pain each having one. The first gate that closes, or feels the input, stops the other gate from closing. Basically, the fastest signal wins out and shuts the other gate to the pain. Vibration travels faster than pain, so it gets to the gates first. That’s a very simplified explanation of course, but it’s why you rub something when you hurt it – the vibration from the rubbing reduces the pain. TENS units may also work by stimulating endorphins. We don’t really know. So it is rather a bold and definitive statement to say that Livia (i.e. a TENS) unit in an off switch. It’s more like kind of sort of maybe and other things.
As TENS technology for period pain has been around for a long time it seems rather disingenuous to call it “new.” And then there is the $85 cost – you can get a decent one on Amazon for $30.
So absolutely talk with your doctor and/or a physical therapist about a TENS for painful periods. They can really be helpful, but until Livia can prove head to head it is better than a TENS or release some kind of data to there is a biologically meaningful difference between their device and a TENS, it is just an expensive, albeit pretty, TENS unit.
