There…
Read MoreImpact of sex and depressed mood on the central regulation of cardiac autonomic function
I think it reads better using “gender” not “sex”. But the conclusion is interesting nonetheless. I didn’t realize that depression and other mental conditions were more correlated with heart disease in women than men. I’m glad they included HFnorm values, something I can understand. The full article is behind a paywall, so not available to…
Read MoreRAVANS:TAVNS exhalation synchronized stimulation
This study by friend of blog Vitaly Napadow, looks at TAVNS (type of ear stim I use in the clinic) and the effect of timing with breathing, exhalation versus inhalation. They are also able to calculate second by second HF HRV. This detailed level of HRV monitoring is way beyond my capabilities. It gives me…
Read MoreModulation of brainstem activity and connectivity by respiratory-gated auricular vagal afferent nerve stimulation in migraine patients.
This study combines two key areas I’m interested in. One is using auricular vagal stimulation, and the other is migraine. Napadow has been a colleague of mine for over 10 years and he does brilliant work. He’s an expert in brain imaging and fMRI. Frankly, I’ve hesitated to use ear stim in migraine patients because…
Read MoreEvoked Pressure Pain Sensitivity Is Associated with Differential Analgesic Response to Verum and Sham Acupuncture in Fibromyalgia
This is an important observation and conclusion, that not all patients are alike in their response to needling. Some patients prefer, if not require light needling. I did a poster presentation on this very topic in Stockholm. The more general take away, is that there is definitely a role for “precision medicine” in acupuncture; better…
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 MoreHypothalamus and Amygdala Response to Acupuncture Stimuli in Carpal Tunnel Syndrome
This article is almost 10 years old, but apparently I’ve never posted it on the blog. It’s pertinent to the autonomic piece of the puzzle that I’m trying to solve re:acupuncture results. Hypothalamus and Amygdala Response to Acupuncture Stimuli in Carpal Tunnel Syndrome V Napadow,1,2 N Kettner,2 J Liu,1 M Li,1 KK Kwong,1 M Vangel,1 N Makris,3 J Audette,4 and KKS Hui1 Abstract Brain…
Read MoreAcupuncture Stimulation and EEG fMRI
Carefully done study in healthy volunteers looking at stimulation of St36 compared to nonacupuncture points. Mu wavelength increases with acupuncture stim, not with stim to nonacupuncture points. This suggests that there is a pain inhibitory effect through the mu activity that is triggered by acupuncture at acupuncture points, but not at nearby points. Full…
Read MoreInnvervation of the External Ear
This is a paper giving backup data for my current work on Heart Rate Variability and Ear Acupuncture. It dissects and identifies various contributions to ear innervation from the Auricular branch of the vagus, the Greater Auricular Nerve, and the Auriculo temporal nerve. Peuker_Clin_Anat_2002 In my recent work, I’ve been needling the cavum concha. According…
Read MoreElectrical Ear Stim leads to Smaller Infarct Size in Rats
This is of interest since my recent bedside research has been looking at the effects of ear stim on the last 5 minutes of acupuncture treatment. In general, I do see a decrease in LF/HF, or decrease in stress response with ear stim. Bain Stimul. 2015 Jan-Feb;8(1):7-12. doi: 10.1016/j.brs.2014.09.009. Epub 2014 Sep 28. Electrical Stimulation…
