New Taipei City, Tamsui DistrictAges 20 years+ - NCT06744413Recruiting
Prehabilitation to improve heart rate variability before cancer surgery
This trial tests whether a personalized prehabilitation program, delivered via a smartphone app, can improve heart rate variability (a measure of nervous system health) in people preparing for major cancer surgery. Participation may help you recover better after surgery.
CataniaAges 18 years+ - NCT06687057Recruiting
Heart rate training for anxiety and stomach issues
This study tests whether a special breathing and heart-rate training program (called HRV biofeedback) can help people who have both anxiety and a sensitive stomach or bowel (functional gastrointestinal disorder). If you often feel anxious and have belly discomfort without a clear medical cause, this training might improve both your digestion and your mood.
MilanAges 18 years+ - NCT06591533Recruiting
Music therapy for children during breathing tube removal
This study uses music therapy to help children stay calm and have stable vital signs while their breathing tube is removed. It may help reduce stress during this important step.
Bogotá, Bogota D.C.Ages 1 month–17 years - NCT06537258Recruiting
Heart rate and stress in teens with IBD
This study tests whether a virtual program can help teens with IBD who also have depression or anxiety. It looks at how stress affects the body through heart rate patterns and aims to improve both gut and emotional health.
Atlanta, GeorgiaAges 13–18 - NCT06011018Recruiting
Mirror Therapy with Electrical Stimulation or Sound Beats after Stroke
This study tests if combining mirror therapy with either gentle electrical stimulation or special sound beats can help improve leg movement and brain activity after a stroke. It is designed for people who had their first stroke at least 6 months ago and have some movement in their leg.
Kaohsiung CityAges 20–80 - NCT06445933Recruiting
Vitamin B6 for depression in pregnancy and after birth
This trial tests whether taking Vitamin B6 can help prevent depression in pregnant women and new mothers. If you are between 24 and 28 weeks pregnant and have no history of mental health conditions, you may be able to join.
TaipeiAges 20–50 - NCT06455527Recruiting
Heart-guided brain stimulation for depression
This trial tests whether a non-invasive brain stimulation technique called tDCS, guided by your heart rate, can help improve depression symptoms. If you have mild to moderate depression and are not on medication, you may be eligible.

Common questions
- Are there clinical trials for heart rate variability?
- Yes. Clin2 currently lists 74 recruiting heart rate variability studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a heart rate variability trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a heart rate variability trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
