Can a simple stretch beat foam rolling for flexibility?
NCT ID NCT07078734
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests two techniques—a therapist-assisted stretch called the Mulligan straight leg raise and self-administered foam rolling—to see which better improves hamstring flexibility in healthy young adults with tight hamstrings. Participants will be randomly assigned to one of the two methods, and flexibility will be measured immediately after using standard tests. The goal is to find a quick, effective way to ease muscle tightness that can contribute to back pain and other issues.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Foam roller and therapist-assisted Mulligan straight leg raise technique
- What this could lead to
- If one technique proves more effective, it could point to a simple, drug-free way to improve flexibility and reduce the risk of related problems like low back pain.
- What could go wrong
- This is a small, early-stage study in healthy young adults, so results may not apply to everyone. The effects are measured immediately, so long-term benefits are unknown.
