Summary
This pilot study tested a small device that stimulates nerves in the ear to help people with cyclic vomiting syndrome, a condition causing repeated bouts of severe nausea and vomiting. Forty-seven children and adults used the device either during an episode or daily for six weeks. Researchers measured changes in nausea, vomiting, and pain to see if the device could provide relief.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- percutaneous electrical nerve field stimulator (ear device)
- What this could lead to
- If it works, this could offer a non-drug option to reduce nausea and vomiting during episodes of cyclic vomiting syndrome.
- What could go wrong
- This is a small pilot study with only 47 participants, so results may not apply to everyone. The device may not work better than a sham (placebo) treatment.
