tVNS for Autism
This article takes an in depth look at the theoretical reasons to use tVNS for autism disorders. The recommended frequencies are here “A recent tVNS study in migraine patients showed that although both 1 and 25 Hz tVNS can improve clinical outcome in patients with chronic migraine, 1 Hz tVNS can produce greater improvement than…
Read MoreTVNS in Tinnitus Patients, HRV study
As some of my patients know, I’ve been using tVNS, or transcutaneous vagal nerve stimulation in some of my patients. I do it by stimulating the ear in the cymba concha region. Some patients have opted to take a device home with a custom electrode that I make for them. This paper corroborates the efficacy…

Frøkjaer JB1,2, Bergmann S1,2, Brock C3,4, Madzak A1, Farmer AD3,5,6, Ellrich J7, Drewes AM2,3. Author information Abstract BACKGROUND: The parasympathetic nervous system, whose main neural substrate is the vagus nerve, exerts a fundamental antinociceptive role…

This has been a satisfying case. Blood pressure and anxiety are well under control and her HRV data is interesting also. I’ve been treating her for a few months and we are exploring use of the customized ear stim device that I’ve been prototyping for home use to help decrease stress levels. In this…
Read MoreChronic Fatigue Syndrome: HRV, Moxibustion and Acupuncture
In this new study from Gerhard Litscher (friend of blog) hrv-moxa-and-chronic-fatigue-litscher, they compare a control group (healthy volunteers), acupuncture group, and moxibustion group. They then compare their chronic fatigue scores, their HRV scores before during and after acupuncture at the 4th and 10th visit. He was kind enough to send me the article in…
Read MoretVNS (Transcutaneous Vagal Nerve Stimulation) for Depression: Improves Default Mode Network
I have done some tVNS similar to that described here in the clinic. The stress (HRV) results are consistent within a patient, but not across patients groups. I’m not sure why, but I’m working on it. Biol Psychiatry. 2016 Feb 15;79(4):266-73. doi: 10.1016/j.biopsych.2015.03.025. Epub 2015 Apr 2. Transcutaneous Vagus Nerve Stimulation Modulates Default Mode…
Read MoreVagal Nerve Stimulation in Pediatric Epilepsy Patients
This is a very interesting article in that, intermittent vagus nerve stimulation lead to decreased parasympathetic tone. Apparently children with epilepsy can have too much vagal tone and if you decrease it, it leads to better adaptability. Dev Med Child Neurol. 2011 Dec;53(12):1143-9. Autonomic effects of refractory epilepsy on heart rate variability in children: influence…
Read MoreScooped! Ear Stimulation and HRV
Turns out someone has done part of my study! Granted, they didn’t incorporate acupuncture and they used a slightly different part of the ear, AND 30hz instead of 2 hz. They showed an increase in HRV in their subjects, which I have not consistently shown in the clinic. Noninvasive vagus nerve stimulation in healthy…
