Could a simple wristband replace drugs for severe morning sickness?
NCT ID NCT07613814
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a vibratory wristband worn on the inner wrist for 15-20 minutes to reduce nausea and vomiting in 240 pregnant women with hyperemesis gravidarum (severe morning sickness). The device stimulates a pressure point (P6) thought to calm the stomach. Researchers measured symptom changes using a standard questionnaire. If effective, it could offer a non-drug option for managing this debilitating condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vibratory Emesis Massage wristband (device)
- What this could lead to
- If it works, this could offer pregnant women a simple, drug-free way to reduce severe nausea and vomiting at home.
- What could go wrong
- This is a small, single-hospital study with no blinding, so results may not apply broadly. The device may not work for everyone or could cause mild skin irritation.

Inclusion Criteria: * Pregnant women diagnosed with emesis gravidarum or hyperemesis gravidarum. * Gestational age within the first, second, or third trimester (with a focus on those experiencing active nausea and vomiting symptoms). * Aged between 18 and 45 years. * Admitted to or receiving care at Prof. Dr. Chairuddin Panusunan Lubis Hospital, University of North Sumatra. * Willing to participate in the study and capable of providing written informed consent. Exclusion Criteria: * Pregnant women with severe medical complications unrelated to hyperemesis (e.g., severe cardiovascular disease, active skin infections, or open wounds at the Pericardium 6 / P6 acupoint area on the wrist). * Patients receiving concurrent alternative non-pharmacological therapies for nausea and vomiting that could confound the study results. * Patients who are unable to complete the assigned 15-to-20-minute Vibratory Emesis Massage (MVE) sessions due to acute physical or cognitive distress. * Participants who choose to withdraw from the hospital treatment or study protocol before the post-test evaluation is completed.
