An earlier blog on Health Rising featured an astonishing story of a woman whose very severe fibromyalgia was largely ameliorated by a vagus nerve stimulator implant. MeSH Prevention and treatment information (HHS). The effects of tVNS parameters on autonomic function in 48 healthy participants were investigated using heart rate variability (HRV) and microneurography. The response to taVNS showed parameter specificity with few nonresponders to the tonic paradigm responding to the burst paradigm. Therefore, a selective test of VN function may be very useful. Neurology Today. There are a number of branching nerves that come in contact with the heart, lungs, larynx, stomach and ears. Active tVNS significantly increased HRV in healthy participants (P = 0.026) indicating a shift in cardiac autonomic function toward parasympathetic predominance. The invention involves the use of an energy source comprising magnetic and/or electrical energy that is transmitted non-invasively to, or in close proximity to, a selected nerve to temporarily stimulate, block and/or modulate the signals in the selected nerve such that neural pathways are vagus nerve. Stimulation via the auricular branch of the vagus nerve of the left tragus was delivered three times per day for 9 months.
