Ear stimulation and heart rate measurement study
This study tests how long a gentle ear stimulation affects heart rate variability, which is a measure of how your heart responds to stress. It may help understand the body's nervous system better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 40 years old
- You are generally healthy with no heart or nerve conditions
- You can avoid caffeine, nicotine, and heavy exercise before the test
- You have no ear infections or skin problems in your ear
- You are willing to try a mild ear stimulation device

This study tests a small device that stimulates a nerve in your ear (not invasive, no needles) for different lengths of time to see how it affects your body. It is for healthy adults and does not involve any drug or surgery.
This trial tests how different electric stimulation settings on the ear (via a small device) affect healthy adults' nervous system functions. It's a research study, not a treatment, to help understand optimal stimulation parameters for future therapies.
This study tests how stimulating a nerve in the ear affects heart rate and stress responses. It may help researchers understand ways to improve heart and nervous system health.
This study compares two ways of measuring heart rate variability (a sign of how well your nervous system is working) during a gentle nerve stimulation therapy. It looks for healthy volunteers to see if a simple arm measurement works as well as a chest measurement.
This trial studies healthy adults to see how heart rate and blood pressure change. It may help researchers understand normal heart function.
This study tests how reliably a small ear-stimulation device measures heart-rhythm patterns. Researchers want to see if the device gives consistent readings across multiple measurement sessions, which could help doctors monitor heart health in the future.
