Home-Based Auricular Transcutaneous Vagus Nerve Stimulation (tVNS) for Sleep Quality and Psycho-Academic Outcomes in Health Sciences Students
Starting soon · Not applicable · Has a placebo group
Conditions studied: Sleep Disturbances, Insomnia, Stress
In brief
This study aims to evaluate the efficacy, safety, and feasibility of a home-based auricular transcutaneous vagus nerve stimulation (tVNS) program in Health Sciences university students with poor sleep quality. Participants will be randomly assigned (1:1) to receive either active auricular stimulation (cymba conchae/tragus) or a control stimulation applied to the earlobe. The intervention will be self-administered at home using a low-frequency TENS-like device for 60 minutes per session, 5 sessions per week for 3 weeks. Sleep quality will be primarily assessed using the Pittsburgh Sleep Quality Index (PSQI) before and after the intervention. Secondary outcomes include insomnia severity, daytime sleepiness, perceived stress, anxiety, quality of life, and psycho-academic outcomes.
