Investigating the Use of taVNS to Treat Insomnia in Individuals With Breast Cancer (taVNS-insomnia-BC)

Transcutaneous auricular vagus nerve stimulation (taVNS) is a form of transcutaneous electrical nerve stimulation (TENS) applied to peripheral nerves, considered a low-risk procedure. It involves the use of standard neurostimulation electrodes placed on the surface of the external ear. The taVNS method delivers low-intensity, pulsed electrical currents with a peak current amplitude of \<4 mA, which is significantly lower than those used in most over-the-counter TENS devices for pain relief or muscle stimulation. By targeting the auricular branches of the vagus nerve, taVNS aims to stimulate specific neural pathways associated with various indications and intended uses. This non-invasive approach has broad applications in research, medical device treatments, health products, and cosmetic or lifestyle products.
