Ozone gel plus sound waves could soothe stubborn shoulder pain
NCT ID NCT07316738
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether applying an ozonated gel with ultrasound (phonophoresis) can reduce pain and improve shoulder function in people with chronic supraspinatus tendinitis. Forty adults aged 30-60 with mild to moderate tendon issues will receive either the ozone gel treatment or standard care (heat and exercises) for four weeks. Researchers will measure pain, range of motion, and disability before and after treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ozonated gel
- What this could lead to
- If it works, this could offer a new, non-invasive way to ease shoulder pain and improve movement for people with chronic tendinitis.
- What could go wrong
- This is a small, early-stage trial with only 40 people. The treatment may not prove more effective than standard care, and results may not apply to everyone.
