electroCore Inc. has announced the publication of a peer-reviewed paper detailing a controlled study on its proprietary TAC-STIM™ non-invasive transcutaneous vagal nerve stimulation (tVNS) device. The research, which involved 70 active-duty United States Air Force trainees, demonstrated that the TAC-STIM device significantly enhanced operational performance, resilience, and skill acquisition during the most intensive phase of Military Qualification Training. These benefits, including improved mood and sustained resilience, were observed across four consecutive days. The findings, described as the first of their kind in an active-duty operational setting, will be presented at the Applied Human Factors and Ergonomics (AHFE2025) Conference on December 8, 2025.
