Auricular Vagal Stim RAVANS and Migraine

By | August 14th, 2017|Autonomic Nervous System|

Ancient Medicine Made Modern This study looks at using interictal (between migraine attacks) auricular stimulation coordinated with exhalation with detailed analysis of brain regions affected.  As far as I can tell, they don't show actual reduction in migraine attacks, but infer that it might happen from the brain changes and connectivity noted.  The [...]

Modulation of brainstem activity and connectivity by respiratory-gated auricular vagal afferent nerve stimulation in migraine patients.

By | August 4th, 2017|Acupuncture research, Autonomic Nervous System|

Ancient Medicine Made Modern: Scientific Solutions, Remarkable Results 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, [...]

Evoked Pressure Pain Sensitivity Is Associated with Differential Analgesic Response to Verum and Sham Acupuncture in Fibromyalgia

By | April 5th, 2017|Acupuncture research|

Ancient Medicine Made Modern: Scientific Solutions for Remarkable Results 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 [...]

Transcutaneous Vagal Nerve Stimulation (RAVANS) fMRI in Migraineurs

By | April 4th, 2017|Acupuncture research|

Ancient Medicine Made Modern: Scientific Solutions, Remarkable Results 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 [...]

Hypothalamus and Amygdala Response to Acupuncture Stimuli in Carpal Tunnel Syndrome

By | August 8th, 2016|Acupuncture research, Autonomic Nervous System|

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. Abstract: Brain processing of acupuncture stimuli in chronic neuropathic pain patients may underlie its beneficial effects. We used fMRI to evaluate verum and [...]

Acupuncture Stimulation and EEG fMRI

By | March 14th, 2015|Acupuncture research|

Ancient Medicine Made Modern 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 [...]

Innvervation of the External Ear

By | January 18th, 2015|Acupuncture research, Autonomic Nervous System, Heart Rate Variability|

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 [...]

Electrical Ear Stim leads to Smaller Infarct Size in Rats

By | January 14th, 2015|Acupuncture research|

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 [...]

Phantom Needling: Novel Sham Acupuncture Technique

By | August 10th, 2014|Acupuncture research, Autonomic Nervous System, Heart Rate Variability, Stress|

Fractals in Nature: HRV Is One of Them A Vitaly Napadow article which explores using a video camera to suggest that a patient is getting acupuncture, when in fact they are not.  There are many interesting findings.  A key finding that affects my work and conclusions is that vagal enhancement seems to accompany [...]

Acupuncture Evoked Response in Contralateral Somatosensory Cortex Reflects Peripheral Nerve Pathology of Carpal Tunnel Syndrome.

Migraine and Brain Regions

By | March 11th, 2014|Fitness and Health|

Acupuncture Helps With Migraines The reason I'm citing this article is that acupuncture acts on the limbic system.  Migraine, preceded by cortical spreading depression, shows increased connectivity in the limbic/viscerosensory network.  This may give rationale for acupuncture's effectiveness in some migraine cases. Cephalalgia. 2013 Nov;33(15):1264-8. doi: 10.1177/0333102413490344. Epub 2013 May 29. The missing link: [...]

Brain Activation in Acupuncture Local and Distal for Carpal Tunnel Syndrome

By | February 16th, 2014|Acupuncture research|

Whole article is here. If I ever get around to learning all the brain areas, I might be able to comment better on this study.  Fascinating that the local and distal both worked better than the sham acupuncture on the affected limb. Evid Based Complement Alternat Med. 2013;2013:795906. Acupuncture-evoked response in somatosensory and prefrontal cortices predicts [...]

Auricular Stimulation for Pelvic Pain Control

By | May 26th, 2012|Acupuncture research, Autonomic Nervous System|

Friend of blog, Vitaly Napadow, has an interesting study looking at ear stimulation for pelvic pain.  His group used transcutaneous-vagus nerve stimulation (t-VNS) synchronized with the exhalation phase of respiration to study the response to chronic pelvic pain.  They compared this synchronized auricular stim to non-vagal auricular stim.  This is a patient population characterized by [...]
