Effect of Vagal Nerve Stimulation on Anxiety and Sleep Disturbances among Geriatric Population: A Pilot Study

Abstract

Background: Anxiety during the COVID-19 pandemic has been a significant concern for people of all age groups,
including geriatric individuals. The elderly population has faced unique challenges during this time, which can
contribute to increased anxiety levels. The uncertainty and fear surrounding the pandemic can lead to increased
anxiety and stress, which can negatively impact sleep quality and duration.
Purpose: The aim of this study is to find out the effect of vagal nerve stimulation on anxiety and sleep disturbances
among geriatric population.
Methodology: Using the Purposive Sampling method, a total of 20 individuals were chosen based on the inclusion
and exclusion criteria. The participants were divided into two groups using the closed envelope method, and they
took part in therapy sessions lasting 30 minutes, three times per week for a period of four weeks. The control group
received Jacobson’s progressive relaxation technique, whereas the experimental group received non-invasive
Transcutaneous auricular vagal nerve stimulation.
Result: With a p value of 0.001, transcutaneous auricular vagal nerve activation significantly improved sleep
quality and reduced anxiety after 4 weeks.
Conclusion: Study showed that transcutaneous vagal nerve stimulation was effective in reducing Anxiety and
improving sleep quality in geriatric population.
