Read MoreTAVNS, or Non-invasive stimulation of vagal afferents reduces gastric frequency.
It is not surprising that transcutaneous auricular vagal nerve stimulation would affect the GI system since it is innervated by the vagus. But this study makes the connection in an elegant way. But pointing out that the end organ, the stomach, is affected by TAVNS, you see the actual, real life results of this intervention. …

This article by a similar group makes a somewhat startling conclusion, but one which I had noticed in the clinic and thought it was spurious. Only in male participants, TVNS was superior to sham and placebo conditions in the reduction of heat pain before the onset of TSP. I don’t look at pain thresholds, but…
Read MoreTranscutaneous vagal nerve stimulation may elicit anti- and pro-nociceptive effects under experimentally-induced pain – a crossover placebo-controlled investigation.
I met Usichenko in Barcelona at a conference there. I was giving a talk and he was in the audience. I wish I had been able to spend a bit more time with him. He seems interested in the same things I am. In my next post, I will link to a more recent study….
Read MoreEar Stimulation (TAVNS) to slow down aging process
It seems we’re finding uses for TAVNS everywhere! They call it “tickling” which I think is great marketing. Come to think of it, I should be doing more of it for myself, in addition to acupuncture… I’m adding an update here to emphasize an interesting takeaway. Subjects in this study who had higher sympathetic activity…
Read MoreTAVNS Parameters and Devices: DyAnsys
In going through previous blog posts concerning TAVNS, I came across this recent post about a company called Dyansys. Their device incorporates my dream project of having an HRV device attached to a peripheral stim device. There are aspects of this device I really like. One tracks the HRV during attachment. Apparently if the sympathetic…

In the spirit of “there’s no bad data only bad hypotheses” I share this data. This is from a long time patient (>3 years) who comes monthly for cosmetic acupuncture. I’ve tried TAVNS on her a few times and the results show in increase in her sympathetic/parasympathetic balance to a dramatic degree. Not once, not…
