(TaVNS =Transcutaneous Auricular Vagus Nerve Stimulation) We have discussed this patient’s case before and here. She is still having trouble with congestion, but her stress levels continue to decrease. She is using a custom electrode I made for her at home a few times a week. So this blog post is an update showing her continuing improvement. I am noticing this more and more that the reduction in Lfnorm (sympathetic activity) is more pronounced with TaVNS than an increase in Parasympathetic Activity (HFnorm). I think this is because LF norm reflects sympathetic activity and some parasympathetic activity. It is also possible that activating the Auricular Branch of the Vagus Nerve (TaVNS) affects the brain in a way to feedback on the sympathetic arm of the autonomic nervous system. Patient is receiving Acupuncture in addition to TaVNS.
