Insulin gel and ultrasound: a new combo to fight joint inflammation?
NCT ID NCT07790757
First seen Aug 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This trial tests whether applying insulin gel to the skin, combined with therapeutic ultrasound (a technique called phonophoresis), can reduce pain and improve function in people with shoulder joint inflammation. Researchers compare a standard insulin gel with a nano-formulated version that may absorb better. Sixty adults aged 40 to 60 with shoulder inflammation or mild osteoarthritis will receive one of the two gels during physiotherapy sessions. The study measures pain scores, shoulder mobility, and quality of life over 12 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Topical insulin gel (standard and nano-formulated) applied with phonophoresis (ultrasound)
- What this could lead to
- If it works, this could offer a new, non-invasive way to reduce joint inflammation and improve shoulder function without injections or surgery.
- What could go wrong
- This is an early-phase trial with only 60 participants, so results may not apply broadly. Insulin can cause low blood sugar or skin irritation, and the nano-formulation may not absorb as expected.
