Ear stimulation for capsaicin-induced pain
Part of Brain & nervous system clinical trials.
This study tests whether a gentle electrical stimulation of a nerve in your ear (called transcutaneous auricular vagus nerve stimulation, or TaVNS) can change how your body feels pain caused by a hot pepper extract (capsaicin). It may help researchers find new ways to manage pain without medication.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You are right-handed.
- You are generally healthy with no history of chronic pain.
- You have no metal implants (like a pacemaker) that could interfere with the nerve stimulation.
- You are not allergic to capsaicin (the substance that makes chili peppers hot).

This study tests whether a small device that stimulates a nerve in your ear (called vagus nerve stimulation) can reduce the amount of strong pain medication you need after major abdominal surgery. The goal is to see if it helps manage pain better with fewer side effects.
This study tests whether a mild electrical stimulation of a nerve in your ear can change how you feel pain from a capsaicin (chili pepper) patch on your leg. It may help researchers understand how to treat pain without drugs.
This study tests a gentle stimulation device placed on the ear to see if it helps reduce fibromyalgia pain. It may offer a drug-free option for pain relief.
This trial uses a mild stimulation device on the ear to try to reduce nerve pain after a spinal cord injury. It aims to see if this non-drug approach can help people with chronic nerve pain.
This trial tests whether a gentle electrical stimulation of a nerve in the ear can reduce pain and inflammation in people with psoriatic arthritis. If you have moderate to high disease activity despite stable treatment, you may be able to join.
This study tests a device that sends gentle electrical pulses to your ear to help reduce pain and prevent it from becoming more widespread. It may be an option if you have rheumatoid arthritis and chronic pain that isn't fully controlled by your current medications.
