Auricular Vagal Stimulation for Cardiac Baroreflex Hypersensitivity in Healthy Young Men
This study looks at TaVNS (Transcutaneous Auricular Vagal Nerve Stimulation) versus sham in healthy males. This study shows that cardiac baroreceptivity improves with TaVNS, but not with sham. Also that Heart Rate and LF/HF decrease with TaVNS but not with sham. Nice! Brain Stimul. 2017 May 19. Non-invasive vagus nerve stimulation acutely improves spontaneous cardiac…
Read MoreTranscutaneous Vagal Nerve Stimulation (RAVANS) fMRI in Migraineurs
I have been exploring Transcutaneous Vagal Nerve Stimulation (tVNS) by way of auricular cymba concha stimulation as an adjunct to acupuncture treatment for over two years. This article by friend of blog Vitaly Napadow, looks at TVNS in migraineurs. They up the ante a bit by synchronizing the stimulation (30hz, non-painful stimulation) with exhalation. This…
Read MoretVNS 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 MoreEar Stim Increases Acetylcholine, animal study
This study is looking at learning and memory improvement with auricular stimulation (estim) in animals. As the first sentence says, “Ear acupuncture enhances the secretion of acetylcholine, which has anti-inflammatory effects.” I’ve been using ear stim in the clinic as many patients know. It is purported to enhance vagal activity which leads to acetylcholine release….
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…
Read MoreAcupuncture for Vertigo, Autonomics and HRV: Sh.Ga
This data is from a new patient who has intractable vertigo. Patients with vertigo tend to have higher stress levels in general, and if that improves it may help since treating vertigo can be challenging. She is a 70+ woman who appears younger than her stated age and is otherwise healthy except for this problem….
Read MoreClinical Cases: TVNS only Ma.Mi, Te. Ca
These data sets are in two patients who showed some improvement in their autonomic balance with estim, or Transcutaneous Vagal Nerve Stimulation (TVNS) as shown by HRV. I wanted to see what their data would look like without the needling, just estim. In both cases, they showed improved autonomic balance with lowered sympathetic activity and…
Read MoreTVNS and Depression
This study looks at tVNS and depression. I’ve been studying Transcutaneous vagal nerve stimulation in the clinic. It involves a small ear electrode in addition to traditional acupuncture treatment. In my latest paper submission-journal-of-medical-acupuncture-one-manuscript-for-blog, I show some of the data from these patients. Some feel that it enhances the acupuncture treatment and have opted…
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 MoreAuricular vagus nerve stimulation (TaVNS) and HRV
This study finds that auricular vagus nerve stimulation (which I am currently studying in the clinic along with hrv) leads to improved hrv. I haven’t found that consistently at all. At least not yet… Brain Stimul. 2014 Nov-Dec;7(6):871-7. doi: 10.1016/j.brs.2014.07.031. Epub 2014 Jul 16. Non-invasive vagus nerve stimulation in healthy humans reduces sympathetic nerve activity….
