Read MoretVNS in PTSD patients: Ability to reduce startle and improve HRV
This study evaluates the startle response in patients with PTSD after TaVNS (Transcutaneous Auricular Vagal Nerve Stimulation). They showed less startle and improved HRV compared to sham during head tilt provocation. They made custom ear electrodes, as I’ve been doing in the clinic. This reminds me of one of my favorite articles of all time…
