Tiny study peers inside shoulder tendons after exercise
NCT ID NCT07489937
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to understand how the shoulder tendon changes right after two different exercise programs. Researchers will use ultrasound to measure tendon thickness before and after exercise in 24 adults, some with shoulder pain and some without. The goal is to see which exercise program causes less tendon change and pain, which could guide future rehab advice.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Isotonic exercise program
- What this could lead to
- If successful, this could help design better exercise programs for shoulder pain and recovery.
- What could go wrong
- This is a small, early-stage study with only 24 participants, so results may not apply to everyone. It measures short-term tendon changes, not long-term outcomes.
