研究概览
简要总结
The purpose of this research study is to investigate the effects of different forms of a gentle form of electrical stimulation applied to the ear, known as transcutaneous auricular vagus nerve stimulation (taVNS). The research team is interested in how the different forms affect comfort and tolerability, as well as how well it works.

结局指标
主要结局
Tolerability Measured by Tolerability Questionnaire
时间窗: 3 hours
Tolerability will be assessed with a questionnaire with scores ranging from 0 -10 (with 0 being no irritation or discomfort and 10 being the worst possible irritation or discomfort) for irritation from tingling/tickling/pricking during taVNS.
Tolerability Measured by Self-report
时间窗: 3 hours
The number of participants who reported mild pain with the intervention.
次要结局
- Change in Heart Rate Variability (HRV)(Baseline and 3 hours)
